2009 GMC YUKON HYBRID door lock

Auto Stop
The vehicle has an Auto Stop feature. After a successful
engine start, the engine may turn off and operate in the
Auto Stop mode. Some of the vehicle conditions that
allow the engine to stop running and enter the Auto Stop
mode are:
•Ignition switch is in the ON/RUN position.
•The hood is closed.
•The gear selector is in P (Park), N (Neutral) or
D (Drive).
•The hybrid battery is at an acceptable state of
charge.
•The hybrid battery voltage, temperature or power
limits are not exceeded. In very hot conditions,
Auto Stop may be unavailable until the hybrid battery
has cooled.
•The engine is at operating temperature.
If you are on an incline, the hybrid drive motor can help
keep the vehicle from rolling backwards, even if the
engine is in Auto Stop.With your foot off the brake and the vehicle on level
ground, the hybrid drive motor may cause the vehicle
to roll slowly forward, even when the engine is in
Auto Stop.
Keep your foot firmly on the brake pedal until you are
ready for the vehicle to move.
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 START position
or a remote vehicle start is performed. When the
tachometer needle indicates AUTO STOP, the hybrid
system is on, the engine is not running, but may
Auto Start at any time without notice. SeeTachometer
on page 3-4for more information.
A chime will sound if the driver door is opened while
in Auto Stop as a reminder that the ignition switch is
not in the LOCK/OFF position. Always turn the ignition
switch to LOCK/OFF and remove the key from the
ignition switch when exiting the vehicle.
