GMC 2008 Canyon - Manual (Page 104)

There are several different positions for your shift lever.
PARK (P): This position locks your rear 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)
(Automatic Transmission) on page 2-34. If you
are pulling a trailer, see Towing a Trailer
on page 4-44.
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 brakes before you can shift from
PARK (P) when the ignition key is in ON. If you cannot
shift out of PARK (P), ease pressure on the shift lever by
pushing the shift lever all the way into PARK (P) as you
maintain brake application. Then move the shift lever into
another gear. See Shifting Out of PARK (P) (Automatic
Transmission) on page 2-36.
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 4-30.
NEUTRAL (N): In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only.
