Warning Lights, Gauges, and Indicators
WARNING lights and gauges can signal that something is wrong before it becomes
serious enough to cause an expensive repair or replacement. Paying attention to
the warning lights and gauges could prevent injury.
WARNING lights come on when there could be a problem with a vehicle function.
Some warning lights come on briefly when the engine is started to indicate they
are working.
Gauges can indicate when there could be a problem with a vehicle function. Often gauges and warning lights work together to indicate a problem with the vehicle.
When one of the warning lights comes on and stays on while driving, or when one of the gauges shows there may be a problem, check the section that explains what to do. Follow this manual's advice. Waiting to do repairs can be costly and even dangerous.
