Buick Enclave 2008 Owner's Manual page 112

PARK (P): This position locks your front wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.
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 2-36. If you are pulling a trailer, see
Towing a Trailer on page 4-29.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brake first and then press the
shift lever button before you can shift from PARK (P)
when the ignition key is in ON/RUN. If you cannot
shift out of PARK (P), ease pressure on the shift lever,
then push the shift lever all the way into PARK (P)
as you maintain brake application. Then press the
shift lever button and move the shift lever into another
gear. See Shifting Out of PARK (P) on page 2-37.
REVERSE (R): Use this gear to back up.
Notice: Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission, see If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-19.
