GMC Terrain. Wait-to-Start Light

For diesel engines, the Wait to Start light shows that the engine glow plug system is operating and indicates when the engine can be started.

The rapid-heat glow plug system causes the Wait to Start light to stay on for a shorter time than most diesel engines.

For more information, see Starting the Engine.
