When it comes to knowing when something is wrong with your car, dashboard warning lights are your vehicle’s way of talking to you.
Whether it be just a door not closed right or that check-engine light you can’t ignore, for all of those dashboard warning lights, if they light up every time you start your vehicle, and they do a quick test to make sure things are good and they all go out, that is a good thing.
But, if even one light stays on that indicates a clear problem. If one or more of those dashboard lights don’t even come on at all, now you have a problem, because if any of those dashboard warning lights don’t come on at all, then you can’t know for sure if anything is wrong.
If you don’t know the meaning of these warning lights, or you ignore them, in the best case scenario, something small will quickly escalate into something much bigger, and wallet draining, not to mention potentially dangerous.
Even the most on top of the car owners can get completely bogged down trying to decipher what these warning lights are saying.
“They’re all so different and so mysterious it makes it easy for us to ignore them”, but even if you think you are good, its good to know what these warnings mean just in case you have to pull over and call for help.
Types of Car dashboard warning lights
Those funny little symbols that turn on your car dashboard are meant to help you. Think of them as the car saying “Hey, pay attention, something is happening.
Some of the dashboard symbols are just indicators of functions or services, such as lights being on or cruise control being engaged. Others are safety indicators such as blind spot monitoring, or lane departure warnings, and others serve to indicate something mechanical is going on such as low tire pressure or engine temperature warnings.
Next, colors can be a huge deal with warning lights….
Green or blue lights: If you see blue or green lights illuminated on your dash everything is good. It means the system is on and it is functioning properly. Think of high beams or cruise control – don’t panic about these – they are just informational.
Yellow or orange lights: When you’re cruising along and see an amber or orange light, this is your car saying “Hey, I’m getting close to needing something.” It’s meant to remind you that at some point, there will be services or repairs due, don’t panic because they don’t require immediate action as the lights I will explain next. It could be a fast indicator that your engine coolant level is low, or something is going on with your engine!
Red lights: Now that we have normalized the yellow lights… sorry but red is no joke! If you see any red light flashing on your dashboard – pull over to the side of the road and figure out what is going on. Ignoring a red dash light, is bad, and likely going to lead you to some very expensive repairs or potentially an accident. Some red lights are no-brainers for safety – like ‘forget your seatbelt?’ where others are indicating a potential mechanical failure – like low engine oil pressure, or a failure of the braking system.
Your car’s dashboard is filled with over 100 possible symbols, and the designs and meanings will vary from car-to-car. If the meaning of a warning light is ever unclear, just refer to the owner’s manual for your car.
So be aware that every vehicle is different, and therefore, the dashboards and symbols discussed in this guide may differ from your vehicle.
We hope that you have found this guide useful, remember it is always best to consult your trusted owner’s manual. Don’t worry if some of these lights illuminate momentarily when starting your car – this is part of your car’s systems doing a self-check. If a warning light stays illuminated, you should be observant and see if there is an issue.
Common Warning Lights on Your Car’s Dashboard
- Check Engine Light
- Battery Alert Light
- Engine Coolant Temperature Warning
- Transmission Temperature Warning Light
- Oil Pressure Warning Light
- Tire Pressure Warning Light
- Brake Warning Light
- Traction Control Warnings Light
- Airbag Warning Light
- Anti-lock Brake System Warning Light
- Low Fuel Indicator Light
- Automatic Shift Lock or Engine Start Indicator Light
- Security Indicator Light
- Washer Fluid Indicator Light
- Lane Departure Warning Light
#1. Check Engine Light
Let’s start with the worst of the worst. The check engine light is often shaped like a silhouetted engine, or, in some even harder to miss cases, it will say “CHECK ENGINE” in big, bold, capital letters, and any car guy will beg you to take a picture of a parked car type of hate for the check engine light the most.
There are multiple reasons why it looks scary, but the light has more than one possible meaning since it can be anything related to your car engine and exhaust system.
It could be something as small as a wire that is connected loosely, or a loose or damaged gas cap, or if you’re looking REALLY dumb, a badly worn out O2 sensor. Or it could be something way bigger and more concerning wrong with the car engine itself.
If the check engine light comes on while you are driving, and everything seems to be alright with the car itself, don’t panic, but don’t ignore it either. If the light is illuminated, get the vehicle to a mechanic to run a diagnostic and fix the problem.
Since 1996, all new cars and light trucks sold in the United States have to legally have an On-Board Diagnostic (OBD) system. The OBD is built-in computer that detects emissions and monitors main engine component conditions.
It’s much easier to diagnose a problem with an OBD scan than relying solely on a mechanic’s understanding, you could tighten the cap and fix it yourself. You’ll also save a big, nasty, emission-spitting car from driving its way into oblivion, or within a few thousand miles.
So as described, there exists many reasons why the check engine light may come on the car. Clearly, be sure to see a qualified mechanic for a proper assessment and possible repair.
Some of the most common problems are:
- Loose or damaged gas cap.
- Faulty oxygen sensor.
- Malfunctioning catalytic converter.
- Damaged spark plugs or ignition coil.
- Failing mass airflow sensor.
- Broken or damaged vacuum hose.
- Malfunctioning EGR valve.
- Faulty thermostat.
Lastly, if the light comes on and the vehicle suddenly starts to perform erratic actions and strange noises begin to exist that weren’t there before, stop the vehicle and request a tow.
This means that there is likely a far more serious problem at hand, possibly a misfire that could permanently ruin your car engine. A flashing check engine light means simply that the car is putting you at risk while possibly ruining the powertrain of your car too.
#2. Battery Alert Warning Light
The battery warning light on your vehicle’s dashboard warns you that there’s a problem with your car’s battery or charging system. When you first start your car, your battery light may come on – that’s OK! It’s normal for your battery light to come on when you first turn your vehicle on and will turn off shortly after you start your vehicle.
If your low battery warning light turns on while you’re driving, your battery is no longer being charged by the alternator and you’re running strictly on battery power. This means your car will only run-on whatever charge is in the battery until it eventually runs out and shuts off your car.
The first thing to do is turn off any electrical systems in your car that you can. That means turn off the stereo, air conditioning, heated seats, and anything else that you charge in the car.
You should also turn off your headlights if you believe you can drive without them and can see well enough to do so. This preserves battery life.
A glowing battery light could be indicative of several issues including;
- A loose or corroded battery cable
- An issue with the alternator or voltage regulator
- Damaged plates or cells in the battery
- Faulty wiring in the electrical charging system of the vehicle.
Essentially, a battery light on that dash means there is a battery charging issue. Your vehicle is not receiving adequate voltage from the car battery for it to operate.
Don’t be misled by a situation where the battery light comes on, but the car starts and drives normally. An issue with the battery may be a long-term issue or there could be potential defects with the wiring, alternator or other relevant componentry of the vehicles electrical system.
You should address the issue by immediately bringing your vehicle to a mechanic so they can diagnose and repair the issue.

#3. Engine Temperature Warning Light
The engine temperature warning light (a symbol that looks like a thermometer or the word “TEMP”) is on when the engine’s temperature is too high – your engine is overheating.
If your vehicle’s cooling system is operating correctly, this should never happen. However, you may discover engine overheating caused by some failure in the cooling system (too little coolant can also lead to overheating) that results in damage in the engine.
This engine damage can be severe, and often irreparable, so it is important to take action quickly.
The light will typically give you at least some momentary warning of the serious problem. You should watch the light for the next mile or two, and if the light is still on after, you should stop and turn the engine off.
In any case, it is better to call your local service center, or service on-site service.
#4. Transmission Temperature Warning Light
If the transmission temperature warning light illuminates, the internal components of your transmission are at a critical temperature that my lead to damage. If it lights, you will need to be careful about steep climbs and stop and go driving conditions.
The ideal maximum transmission temperature is 200 degrees Fahrenheit, at which point every 20 degrees higher than 200 will cut the transmission lifespan in half. This could be due to excessive towing weight, low transmission fluid level, or more seriously significant wear on the internal components of the transmission.
The color of the transmission temperature warning light will also inform the urgency of the situation, with red being a more urgent condition that requires immediate attention.
Although you will be doing more damage to your vehicle if you continue to drive with the transmission temperature warning light illuminated, you will ultimately need to have your vehicle inspected by a mechanic as soon as you can to diagnose and repair the identified condition.
#5. Oil Pressure Warning Light
Typically, an oil pressure warning light looks like a genie lamp or an old fashion oil can. This warning light is indicating there is an issue with your engine oil, it could be a low engine oil or low engine oil pressure in the system.
This light will come on the dashboard when the oil pressure in the engine is low and this could be a major problem. If this oil pressure warning light comes on, you should turn off the vehicle and not use the vehicle again until it is fixed. Driving the vehicle with low oil pressure could destroy your engine very quickly.
It is suggested that after driving, give the car approximately 10 minutes before checking the oil level while parked on a semi-level surface.
If the dipstick shows that the oil levels are low and by adding oil turns the light off, then all is not lost. If that doesn’t turn off the light, or the light comes on shortly after adding oil, then have the issue checked as soon as possible.
There are several other possibilities when the oil pressure warning light comes on. Generally, the most common reasons why the low oil pressure light comes on is because of low oil, a faulty oil pump, or possibly major engine issue.
To help prevent the oil pressure warning light from turning on, it is advised that you provide routine maintenance to the vehicle which includes scheduled routine oil changes.
#6. Tire Pressure Warning Light
If your tire pressure warning light is on, either your tires are too low or too high. The light is typically yellow or amber in color, and looks like a cross-section view of a tire with an exclamation point and/or the letters TPMS in it.
When the light is on, it indicates your tires may be underinflated, risking unnecessary tire wear, and possibility of tire failure. You should check your tire pressure from your owner’s manual or tire sticker and check the pressure, adding or removing air from your tires until they are within the recommended range.
For most passenger cars, you will find a recommendation of 32 to 35 psi for the recommended tire pressure when the tires are cold.
If your tire pressure is within specification and appears to have no leaks, but your TPMS warning light is lit, you can attempt to reset your TPMS system by simply driving the vehicle for a minimum of 10 minutes at a speed of 15 mph or higher. If your TPMS light is flashing for a minute and then remains on, the TPMS system has a fault.
#7. Brake Warning Light
The car’s brake warning light can mean many things. The most common reasons that the brake warning light turns on are low fluid levels or the parking brake is engaged.
The brake warning light will also turn on if the brake pads are close to worn out and need to be replaced soon. If the light repeatedly turns off/on or flickers when turning, then that is likely the cause.
If driving your vehicle and the brake warning light comes on, all you can do is find a safe spot to pull over and turn off your car.
After stopping your vehicle and turning it off, first confirm the emergency brake is released. There is no reason good enough to ignore the brake warning light while driving. Ignoring the brake warning light while driving will likely cause further damage to the braking system and can be dangerous.
At this point, it is better to be safe and damage the tow company than to damage your car any further. For this reason, it’s best to have the car towed to a mechanic you trust. Again, since the brake warning light can mean many things, a brake specialist being able to identify the real problem before any other warning lights come on is your best bet.
#8. Traction Control Malfunction Warning Light
The Traction Control Malfunction Light indicates there is a fault in the traction control system.
A traction control system helps keep your vehicle under control when one or more wheels lose traction while driving. An array of faults can cause this light to turn on, including but not limited to, a faulty ABS system, wheel speed sensors, or reductor ring.
This likely won’t affect your day-to-day driving, but I would get it checked as soon as you can to ensure that your vehicle will be able to perform safely when driving in adverse conditions.
#9. Airbag Warning Light
The airbag light can come on because one of your airbags is not working, or your entire airbag system is faulty. This indicates it is likely unsafe to drive with the airbag light on.
If the airbag is not deployed during a crash, on your way to get it fixed, your risk of injury or death will be unimaginably high. Figuring this out is not always straightforward, so it is often easiest for the experts to assist you.
You should get your car checked out as soon as possible! The airbags your car possess are designed to protect you during an accident, so ensure they are working properly.
#10. Anti-lock Brake System Warning Light
ABS stands for anti-lock braking system and when the ABS warning light is on in your car’s instrument cluster, it indicates a system malfunction which has deactivated the vehicle’s anti-lock braking system.
The regular brakes on your vehicle should work fine, this feature just stops braking when you press the brake pedal too aggressively. The anti-lock brakes also stop the wheels from locking up when you brake.
In addition, if your car has stability control and traction control, these systems will also be disabled due to the fact they both rely on the same wheel speed sensors as the ABS itself.
The four most common causes that will activate the ABS light in a car include; ABS module failure, fluid reservoir levels are low, wheel speed sensor failure, or the system is turned off.
#11. Low Fuel Warning Light
A lit dashboard light in the shape of a fuel pump indicates to you that your fuel tank is low.
The only purpose of the low fuel warning light is to let the drivers know when their fuel tank is low. When the yellow gas pump symbol is lit, you need to go to a gas station to replenish the fuel measure in your car’s tank.
Your car’s drivability will not be compromised, and you can still drive your car safely, just do not make a habit of it, how far would you want to drive before refilling your tank? The issue is not being out of fuel and being stranded.
If your light is still on when the fuel tank is full, you could require servicing on your fuel level sensor. Make sure to try premium gasoline as well. Regular gasoline is often lower quality and can contain more contaminants, or contain some water, which is what most likely will affect your fuel level sensor.
If you need further help, it is preferable to take your car to the mechanic.
#12. Automatic Shift Lock or Engine Start Indicator Light
The automatic shift lock light is a shift lock release indicator for your car or vehicle with an automatic transmission. Also referred to as the engine start indicator warning light, it serves two, not so different purposes: (1) this light will come on to let you know that you must first depress the brake to start the ignition of the vehicle, or (2) to shift from neutral into gear.
For your safety, automatic transmissions have a shift lock system that locks out the transmission’s shifting from P (Park) to R (Reverse) when the brake pedal is not depressed. To shift the transmission from P (Park) to R (Reverse): Press the brake pedal and hold it down.
So, just press down on the brake pedal, and then you can change the next gear or start the ignition, whatever you intend to do.
#13. Security Indicator Light
The security indicator light turns on when the key is out from the ignition switch. This indicates that the immobilizer is working. Which means that if someone tries to steal your car, they cannot start the engine.
Some cars have an alarm system too. When you enter a key in the ignition the chip in the that key is scanned, if it matches the code set in the security system, the light will turn off and the immobilizer will turn off also.
If you see the light keep flashing, something is wrong with that key or the security system. When vehicle is stationary, follow the vehicles instructions to disable the security system. If it is a malfunction, the security system will not function properly until repaired.
#14. Washer Fluid Indicator Light
The washer fluid indicator light on your dashboard is a warning for low washer fluid (you need to refill soon). Generally, it is a yellow color with a windshield light showing on the car dashboard. If you do not keep fluid in the tank, the tank will dry out.
Pop the hood of your car and find the windshield washer fluid reservoir. It is generally a white plastic container filled with a blue fluid (which may be a different shade of blue for each brand).
If you see that the windshield washer fluid tank is low or empty, refill it with windshield washer fluid (which is available at almost any gas station or auto repair shop). It should have been noticed the low washer fluid light was illuminated to indicate it was low or empty
Once you have completed the steps of refilling your windshield washer fluid reservoir and closed the windshield washer fluid reservoir as well as the hood of your car, you can use the handle and wash your windows. I would suspect you would have already seen that the washer fluid symbol has deactivated.
#15. Lane Departure Warning Light
The Lane Departure Warning Light is a vehicle safety feature that warns the driver when the vehicle is detected to be drifting out of its current lane without signaling. The warning may be a flashing light and/or a beeping sound from the direction of the drift.
Some systems may also provide a gentle vibration of the steering wheel or driver’s seat. The light would probably be a steady black and white if the lane-keeping system is not ready, would be green if the system is ready, and if the vehicle does drift out of its lane, the system would be gently turning the steering wheel to get the vehicle back into the lane.
It detects the lane markers with either cameras and/or sensors and alerts the driver when the tire departs the lane marker.
Car Dashboard safety symbols
Dashboard safety symbols are indicators that show up on a car’s dashboard to notify drivers of potential problems or safety issues. The symbols can also include warning lights for low fuel, low oil pressure, tire pressure, and engine problems.
The red symbols are concerning and mean you should stop driving immediately! The yellow/orange symbols action needed can be more flexible with priority but require some attention. Drivers must learn these symbols and what they mean for their own safety!
#16. Power Steering Warning Light
The power steering warning light is a red or yellow steering wheel that is typically located on a car’s dashboard next to an exclamation mark. The light indicates to the driver that the power steering system has failed and that they need to check for what caused the light to come on. The cause can vary based on the type of power steering system the car has.
For hydraulic power steering systems, an most common cause for the power steering warning light to come on is a leak in the system resulting in low fluid.
By contrast, EPS on the dashboard in electric power steering systems could prove more difficult to diagnose as there are no fluids to leak. For an electric power steering system, the electrical problem may primarily be with the battery or the alternator. If you have an electric power steering system, it is wise to pop the hood and check the battery or check the alternator.
If the power steering warning light comes on, it would be best to pull over when possible and check for what is wrong. Driving with a failed power steering system could continue to cause safety issues and make the car difficult to steer.
#17. Seat Belt Warning Light
Seat belt warning light tells if a passenger is properly wearing their seat belt or not. The light should go out when the seat belts are secured.
If the seat belt warning light stays on, first consider if the seat belt is secured. Auto makers have a seat belt sensor in the seat belt buckle of both the driver’s seat and front passenger seat.
It also has an occupancy or weight sensor to confirm you have a passenger in the car. If the light stays on and the seat belt is buckled, you may have an issue with the seat belt switch or a connector sending the signal to your car.
A common fix, is to first try to clean out the seat belt buckle. Other option is to buy some electric contact cleaner, and spray it in the seat belt buckle. If that doesn’t work, you will likely need to see your mechanic.
#18. Parking Brake Warning Light
The parking brake warning light indicates that the parking brake/emergency brake is set and must be released before driving. Depending on the brand of vehicle, the light may illuminate in red or orange.
If the light stays illuminated after the parking brake is released, or if it goes off and on while driving, this may indicate that the brake fluid must be checked for top-up. But if the light still stays illuminated after topping-up brake fluid, the brake system must be further investigated by a qualified professional repair.
If you see an illuminated wrench under the parking brake warning light, this means the parking brake requires service. You cannot operate the vehicle while the parking brake is engaged because this may inflict serious damage to the vehicle.
If the brake warning light is on it can be helpful to have a brake professional look at the brake system to identify the actual problem before other warning signs are illuminated.
#19. Master Warning Light/General Warning Light
The Master Warning Light alerts you to an issue in one or more of your vehicle’s advanced systems. When it activates, a specific system message appears shortly after on the car’s information display, usually accompanied by additional warning lights.
What the master warning light indicates and its possible triggers depend on the make and model of your vehicle.
#20. Side Air Bag Off warning light
The Side Air Bag Off warning light on the instrument panel indicates that the passenger-side airbag has been temporarily turned off.
The passenger-side airbag is turned off when the front passenger seat is unoccupied or when the passenger is not in a safe position.
#21. Reduced Power Warning Light
The Reduced Power Warning light indicates that something has reduced fuel and/or air to the engine. The light usually is activated when maintenance or repair is required on the car and does not indicate the vehicle is about to have a catastrophic failure. While this could be a good time to perform an oil change.
When the light is on, the engine is not producing all the power it should. The Reduced Engine Power warning light is initiated by the vehicle’s computer system when it detects a failure in one of the components of the vehicle.
The reduced engine power mode is sometimes referred to as “limp mode.” When vehicles experience a reduced engine power mode condition, the performance of the engine is limited.
#22. Traction Control Warnings Light
When your traction control light flashes or stays on, it is a sign that your tires are losing contact with the road. Your tires may lose traction due to wet roads, icy conditions, or dirt. This may trigger the traction control system and stabilize your car while the traction control light is illuminated as a warning.
The traction control systems are equipped with sensors to detect when a car is about to lose traction. When the system detects a potential loss of traction, it reduces engine power to the wheel.
The system should help the car retain traction so that it stays on the road. If you have a TCS light illuminated on your dashboard, this indicates there is a situation with the traction control system.
#23. Traction Control Off Warning Light
The TCS symbol on the dashboard indicates that your vehicle’s traction control system has been disengaged.
#24. Steering Wheel Lock Warning Light
An indicator light that is illuminated means the steering wheel lock is on and locked in place. The steering lock light is not to be confused with a power steering warning light, which indicates there is an actual steering problem.
To disengage the steering lock, insert the key into the ignition and turn it to at least first position while turning the steering wheel back and forth. You should not need to use excessive force to turn the key to turn and unlock the steering wheel.
The steering wheel lock warning light should illuminate only when the ignition is turned off and the steering lock is engaged. If the steering lock warning light is on outside those parameters, have the vehicle checked by a qualified mechanic.
#25. Trailer Tow Hitch Warning
Typically, the trailer tow hitch indicator light could come on for a few different reasons. Depending on what kind of vehicle you are in this light could mean that the tow hitch is unlocked or that there is a problem with the lighting circuit.
Some vehicles also have an indicator to show that you will have an additional load on the lightening circuit.
#26. Service Vehicle Soon Warning Light
If you see the Service Vehicle warning light come on, then it’s a good idea to get your car checked out by a qualified mechanic. That warning light tells you that there could be a problem with your engine, transmission, fuel, ignition, emissions, or your car’s computers.
First, let’s be clear – you don’t want to take a chance by ignoring that warning light, especially if you could be facing an issue that involves safety, and your brakes & lights. If you see the light on the dashboard is amber; you might have a little more time before needing to have your vehicle checked, but you really should do it as soon as you are able.
#27. Press Clutch Pedal Warning Light
The Press Clutch Pedal warning light is a yellow light showing a shoe with a circle around it, that comes on the dashboard of vehicles with manual transmission as reminder to press the clutch pedal before you start the engine. When the clutch pedal is pressed, the light should go out and you can begin driving.
Bonus Tip: This is not to be confused with the brake pedal warning light (green), which indicates that the brake pedal should be pressed and held if the gear lever should be moved from park.
#28. Powertrain Fault
The wrench warning light on Ford vehicles symbolizes the powertrain malfunction indicator. If illuminated, this is a warning that your vehicle’s computer has detected a problem with either your vehicle’s powertrain, or all-wheel drive (AWD).
A powertrain malfunction light should be taken seriously, because the consequences of ignoring a serious problem can cost you a lot more in repairs to your engine, transmission or powertrain in the long term.
If you experience a performance change in your vehicle like: Engine shaking or reduced performance, consider having the vehicle towed directly to an authorized dealer instead of just driving it yourself.
#29. A/T P Warning Light
The A/T P warning light is an A/T Park (P) indicator warning symbol. This light will come on when a vehicles 4 wheel drive shifter is in the neutral (N) position. You will not be able to engage drive gear until you have manually selected either the 4 Low or the 4 High options.
It could also indicate there is a fault in the park gear of the automatic transmission, which would warrant assistance/diagnosis, and secure the hand/parking brake to the vehicle is secure in the event of a faulty park gear!
#30. Overdrive Light
Overdrive (O/D), you have another gear usually the highest gear in the transmission system. This allows your car to travel at higher speeds with reduced engine RPMs, engine wear, and improved fuel economy.
The O/D OFF light illuminated on your dashboard means the overdrive has been engaged/disengaged and it is usually you or someone else who has done it by hitting O/D on the gearshift. When this happens, your car will no longer shift to the highest gear ratio it can achieve, but remain in a lower gear.
The O/D OFF Light being off means the over-drive function is now engaged, allowing shifts between any gear, whenever needed.
If the O/D OFF light is blinking or flashing, this indicates a problem with the transmission system.
#31. Oil Change Reminder
Oil Change Reminder warning light indicates that oil life has expired and that it is time for an oil change.
Maintenance reminder is self-explanatory. It is always best to make an appointment with an authorized service center where they will take care of the oil change and as part of that service being, will reset your reminder light.

#32. Information Warning Light
The information warning light will illuminate if a message is stored in the information display. It will be a red or amber in color indicating the severity of the information, and it will stay on until the condition described in the display is repaired.
#33. Icy Road Warning Light
The icy road warning light is illustrated as a snowflake on your vehicle’s dashboard with the road lane markers.
It is a warning to the driver that the temperature of the outside air is nearing freezing, i.e., around 35°F or 3°C, and the chance of an icy road ahead exists.
Therefore, it is up to the driver to take precautions and slow the vehicle down.
#34. Gas/Fuel Cap
If your fuel cap light is illuminating it means the computer has detected a leak in the system, and most likely, a loose gas cap. If this light comes on while you are driving, it is best to pull over into a safe location to securely re-fastened the cap, and the light should go out within a day or two.
If the light continues to illuminate, it is advisable to examine the fuel filler neck or gas cap with a certified technician.
The warning light can also mean that the fuel cap is broken, has been lost, or is not put on properly.
#35. Electronic Stability Program (ESP) Warning Light
If the Electronic Stability Program (ESP) warning light has turned on, it indicates that there is something wrong with your electronic stability program system, or you are simply driving on a slippery surface. Under most circumstances, the ESP light will come on while driving a slippery surface, or it will come on when the car initially loses traction.
If the warning light is flashing, this means that the ESP traction control is working to stabilize the vehicle.
If the light is steady, or the light flashes on and off, this can indicate a problem with the system, which could be anything from a steering angle sensor fault to a brake pedal switch fault.
#36. Electric Park Brake Warning Light
Electric parking brake, commonly abbreviated to ‘EPB’ is an advanced version of a standard parking brake (or handbrake). Sometimes people refer to this system as an ‘Electronic Parking Brake.’ It is technically a sub-part of the advanced ‘Brake by Wire’ systems.
The Electric Park Brake warning light is both an Electric Park Brake on Indicator and Fault Indicator. If you see the light while the brake is engaged and ignition is on it may indicate a fault. In most normal circumstances, if the Electric Park Brake warning light goes off the system is working correctly.
If the warning light continues to flash and/or is on while driving this may be an indication of a problem with your electric parking brake. If this is the case, please have the vehicle checked as soon as possible.
#37. Distance Warning
The distance warning light alerts you that your car is going to collide with another car or obstruct an object. When this light comes on, it means the computer has detected an object on the road ahead that is closing at a rapid pace in the same direction as travel.
This does not have to be a car; rather it could be a big object laying on the road. Look for something on the ground when there are no vehicles ahead of you.
#38. Clogged Air Filter light
The Clogged Air Filter Warning Light has one purpose, to inform the driver of decreased airflow into the engine. If this light comes on, you should replace or at least have the air filter inspected. After the filter is replaced you may need to turn the warning light out using a reset button.
A clogged air can cause engine misfires, rough idle and hard starting. Refer to the owner’s manual of your automobile or search online for the placement of the button for resetting the light.
#39. Child Safety Lock Warning
The child safety lock warning light on the dashboard indicates that the child safety locks are engaged. When the child safety locks are engaged, the rear doors cannot be opened from the inside of the vehicle to prevent children from accidentally pulling the door handle while a vehicle is moving.
In order to turn off the child safety lock warning light you need to turn off the child safety locks.
#40. Catalytic Converter Warning Light
The catalytic converter warning light is intended to alert the driver that the catalytic converter is overheating, or that it is not functioning properly. Inside the catalytic converter, it has a honeycomb shape, that increases the contact surface area with the air.
Over time, the metal can break down and restrict the flow of air, our holes will get clogged; hence into the restriction for the catalytic converter, when the catalytic converter isn’t functioning properly, it may turn the check engine light on.
It is generally not advisable to drive with the check engine light on, especially if you have a bad DPF and catalytic converter.
#41. Low Brake Fluid Warning Light
This warning light indicates that the brake fluid is at a low level in the vehicle, this could happen if you have a leak in the braking system, or worn break pads. If your warning light lights up, you should pull over safely and check the brake fluid level. If it is low, you can top the brake fluid up with correct brake fluid.
However, before putting new brake fluid in check the old brake fluid to see if it is dirty or discolored, you may need to flush them. If the warning light comes on again after adding brake fluid you will need to have your brake system inspected for other possible problems by a professional.
#42. Brake Pads Warning Light
This is warning light is indicating that brake pads are worn and will need to be replaced soon. It may also activate if the master cylinder’s sensor detects a low brake fluid level.
The light is generally depicted as a circle encased in dotted brackets. If the light illuminates, you should have your brake pads inspected and possibly replaced to ensure you have sufficient braking safety during normal driving conditions.
#43. Brake Lights Warning
