Tire Pressure Warning Light
The tire pressure warning light, also known as the Tire Pressure Monitoring System (TPMS) symbol, indicates an issue with your tire pressure. If the symbol is solid, it suggests that one or more of your tires have low or high pressure. If the symbol flashes briefly upon starting the vehicle and then stays even if your tires are properly inflated, there may be a problem with the TPMS sensors.
The TPMS typically displays a warning light on the dashboard, indicating which tire or tires are affected and the amount of pressure loss. In some cases, such as with newer BMWs, you may receive a message indicating whether it is safe to continue driving.
Driving with improperly inflated tires is unsafe and can lead to tire damage and uneven wear. It is recommended to stop as soon as possible and adjust the tire pressure to the correct level. Drive to an auto repair shop so they can also inspect the TPMS sensors and provide a quote for any necessary repairs. While a malfunctioning TPMS won’t affect tire performance, it will prevent the system from alerting you about low tire pressure.
Washer Fluid Indicator Light
The washer fluid reminder light resembles the motion of windshield wipers and indicates that the washer fluid in your car is low and needs to be refilled.
Fortunately, this is a problem that can be easily addressed at home. As soon as the light illuminates, filling up the washer fluid reservoir with the appropriate fluid is recommended. It is a good practice to keep a bottle of all-season washer fluid in your garage for such occasions.
Engine Temperature Warning Light
The engine temperature warning light is designed to indicate when your engine is overheating. It can appear in different forms, such as a thermometer symbol. When you start the car, the light may initially illuminate in blue, indicating the engine is still cold. However, if it turns red, it signifies that the engine temperature has exceeded safe levels.
It can be triggered by various issues, such as low coolant levels due to leaks, a malfunctioning coolant pump, or a faulty thermostat. More severe cases may indicate significant problems like a blown head gasket or a damaged radiator.
When the engine temperature warning light comes on, it is important to take immediate action.

Allowing the transmission to cool down is necessary before attempting to drive again. It is recommended to seek professional help by taking your vehicle to a repair shop as soon as possible to diagnose and address the underlying cause of the overheating. If the warning light persists and you have a considerable distance to travel, it is advisable to call for a tow to avoid further damage to the transmission.
Traction Control Light
The traction control light indicates that your vehicle’s traction control system is activated. The traction control system utilizes the anti-lock brake system (ABS) to monitor and regulate the speed of individual wheels. If it detects wheel slip, it applies the brakes to that specific wheel to help regain traction. This feature is particularly useful when driving in slippery conditions such as rain or snow.
If the traction control light is illuminated, it means that the system is active and helps to maintain traction. It is important to be aware of the potentially slippery conditions and adjust your driving accordingly. Continue driving, but exercise caution and be mindful of the road conditions to ensure safe and controlled driving.
Lane Departure Warning Light
The lane departure warning light is a safety feature present in many modern cars. It illuminates the dashboard and may emit a beeping sound when it detects that the vehicle is drifting out of the lane.
If the lane departure warning light comes on and you are unintentionally drifting out of your lane, correct your steering to stay within the lane. Paying attention to the road and avoiding distractions is important to ensure safe and accurate driving. However, it is normal for the light to activate when intentionally changing lanes.
Being knowledgeable about the dashboard lights makes it easier to identify problems and determine how quickly they need to be resolved. Familiarize yourself with the symbols by referring to your car’s owner’s manual. Additionally, learning about these symbols can help you discover hidden features your car may have.
