Diagnostic Aids

WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.

A chime will sound if the drivers door is opened while in Autostop as a reminder that the engine is not in the OFF mode.

Engine OFF and AUTO STOP modes are indicated on the tachometer display.

When the tachometer needle indicates OFF, the engine is not running and will remain Off until the ignition key is placed in the Crank position or a remote vehicle start request is received from the keyless entry transmitter. Autostop is not allowed with a remote vehicle start.
When the tachometer needle indicates AUTO STOP, the engine is not running but may Autostart at any time without notice.
