Common Warning Lights and Their General Meanings:
* Check Engine Light (usually an engine icon): This is the most common warning light. It indicates a problem with the engine or emission control system. It could be something minor (loose gas cap) or something serious (faulty sensor or catalytic converter). A diagnostic scan tool is needed to get a specific code to diagnose the issue.
* Brake System Warning Light (usually a circle with an exclamation point inside): This usually indicates a problem with the braking system, such as low brake fluid, a faulty brake light, or a problem with the anti-lock braking system (ABS).
* ABS Warning Light (usually an ABS acronym or an icon of a car with skidding wheels): Indicates a problem with the anti-lock braking system. Your brakes will still function, but ABS will be disabled.
* Airbag Warning Light (usually a picture of a person with an airbag deploying): Indicates a problem with the airbag system. This requires immediate attention from a qualified mechanic.
* Security Warning Light (often a key or a lock icon): Indicates a problem with the vehicle's security system.
* Battery Warning Light (usually a battery icon): Indicates a problem with the charging system or the battery itself.
* Oil Pressure Warning Light (usually an oil can icon): This is a very serious warning indicating low oil pressure. Stop driving immediately and check your oil level. Driving with low oil pressure can severely damage the engine.
* Temperature Warning Light (usually a thermometer icon): Indicates the engine is overheating. Pull over safely and let the engine cool down before proceeding.
* Low Fuel Warning Light (usually a fuel pump icon): Indicates that your fuel level is low.
* Seatbelt Warning Light (usually a picture of a seatbelt): Reminds you to fasten your seatbelt.
* Traction Control Warning Light (usually a car with skidding wheels and a line underneath): Indicates a problem with the traction control system.
* Tire Pressure Monitoring System (TPMS) Warning Light (usually a picture of a tire with an exclamation point): Indicates that one or more tires have low pressure.
