Automatic Transmission Operation - GMC 2008 Envoy Denali Owner's Manual

Automatic Transmission Operation

PARK (P): This position locks the rear wheels. It is the
best position to use when you start the engine
because your vehicle cannot move easily.
2-26
There are several different
positions for your gear shift
lever.
CAUTION:
{
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
See Shifting Into PARK (P) on page 2-34. If you
are pulling a trailer, see Towing a Trailer on
page 4-45.
