Car dashboards have become increasingly complex, with a multitude of lights and symbols designed to alert drivers to potential issues.
Deciphering the meaning of those flashing car dashboard warning lights can be confusing.
Common Car Warning Lights and Their Meanings
Battery Warning Light
This light, typically shaped like a battery, indicates a problem with your car’s charging system. If it comes on while your engine is running, it could signal a faulty alternator, battery, or a loose connection.
Oil Pressure Warning Light
This light, often depicted as an oil can or a pressure gauge, warns of low oil pressure. If it illuminates, you should stop driving immediately and check your oil level. Continuing to drive can cause severe engine damage.
Engine Temperature Warning Light
This light, usually shaped like a thermometer or a radiator, indicates that your engine is overheating. If it comes on, stop driving as soon as possible and allow your engine to cool down. Overheating can lead to serious engine problems.
Brake Warning Light
This light, typically shaped like a circle with an exclamation mark, indicates a problem with your braking system. It could signal low brake fluid levels, a faulty brake light, or a problem with the parking brake.
ABS Warning Light
This light, often depicted as a circle with letters “ABS,” indicates a problem with your anti-lock brake system. If it comes on, your ABS may not function as intended, but your regular brakes should still work.
Check Engine Light
The check engine light, also known as the service engine soon light, can indicate a variety of issues. It could be something minor, like a loose gas cap, or something more serious, like a sensor malfunction or engine problems. If the light comes on, it’s recommended to have your vehicle checked by a mechanic.
Airbag Warning Light
This light, typically shaped like a steering wheel with an airbag symbol, indicates a potential problem with your airbag system. If it comes on, have your vehicle inspected by a professional as soon as possible
What to Do When Car Warning Lights Come On
If a car dashboard warning light illuminates, don’t panic. However, it’s important to take the issue seriously and address it promptly. Here are some general guidelines:
| Stop Safely: If the warning light indicates a serious problem, such as low oil pressure or overheating, stop driving as soon as possible in a safe location. |
| Check the Manual: Consult your car’s owner’s manual for specific information on the warning light and the recommended course of action. |
| Don’t Ignore the Issue: Avoid driving with a warning light illuminated, as it could lead to further damage or safety hazards. |

| Door ajar indicator: A small icon of an open door indicates that a door or the trunk is open. |
| Fuel gauge: This symbol shows the remaining fuel level in your tank. |
| Headlight indicator: A symbol of a headlight indicates whether your headlights are on. |
| High beam indicator: A symbol of a headlight with one beam higher than the other indicates when your high beams are on. |
| Turn signal indicators: Arrows pointing left or right indicate the direction of your turn signal. |
| Cruise control indicator: A symbol of a car with a speed limit set indicates that cruise control is activated. |
| Wiper/washer fluid indicator: A symbol of a windshield with water droplets indicates the wiper and washer fluid status. |
| Temperature gauge: This symbol shows the engine’s coolant temperature. |
| Transmission gear indicator: This symbol shows the current gear selected in your transmission. |
