Retained Accessory Power (Rap); Starting The Engine - GMC 2008 Envoy Denali Owner's Manual

Key In the Ignition
Never leave your vehicle with the keys inside. If you
leave the key in the ignition and park your vehicle, a
chime will sound, when you open the driver's door.
Remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.

These vehicle accessories can be used for up to
20 minutes after the engine is turned off:
•

2-22
These features will work when the key is in ON/RUN
or ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF, these features continue to
work for up to 20 minutes, or until a door is opened.

Starting the Engine

Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position – this
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice: Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
