Understanding how to check warning lights in your car is essential for maintaining vehicle safety and performance. Drivers often encounter dashboard warning lights that indicate various issues, ranging from minor alerts to serious malfunctions. This guide will help you identify these lights, understand their meanings, and determine the appropriate actions to take.

Understanding Dashboard Warning Lights

Dashboard warning lights are color-coded signals that alert drivers to potential problems with their vehicles. The three primary colors used are:

  • Red: Indicates a serious issue that requires immediate attention. You should stop driving as soon as it is safe.

  • Yellow/Amber: Signals a less urgent problem that needs to be checked soon. Driving is generally safe, but you should seek repairs promptly.

  • Green/Blue: These lights indicate that a system is functioning normally or is currently in use.

Recognizing these colors can help you prioritize your response when a warning light appears.
