GMC Terrain: Warning Lights, Gauges, and Indicators / Warning Lights, Gauges, and Indicators

GMC Terrain 2018-2026 Owners Manual / Instruments and Controls / Warning Lights, Gauges, and Indicators / 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.

Some warning lights come on briefly when the engine is started to indicate they are working. 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. Waiting to do repairs can be costly and even dangerous.
