Automatic Transmission Operation - GMC 2010 Canyon Crew Cab Owner's Manual

Automatic Transmission Operation

The vehicle has a shift lever on the steering column.
It features an electronic shift position indicator within the
instrument cluster. This display is powered anytime
the shift lever is capable of being moved out of P (Park).
This means that if the ignition is turned off, but not in
LOCK/OFF, there will be a small current drain on
the battery which could discharge the battery over a
period of time. If you need to leave the key in the ignition
but not in LOCK/OFF for an extended period, it is
recommended that you disconnect the battery cable
from the battery to prevent discharging the battery.
There are several different positions for the shift lever.
P (Park): This position locks the rear wheels. It is
the best position to use when you start the engine
because the vehicle cannot move easily.
WARNING:
{
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park (Automatic Transmission) on page 3-31.
If you are pulling a trailer, see Towing a Trailer on
page 5-48.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must fully
apply the brake pedal before you can shift from P (Park)
when the ignition key is in ON/RUN. If you cannot
shift out of P (Park), ease pressure on the shift lever by
pushing the shift lever all the way into P (Park) as
you maintain brake application. Then move the shift
lever into another gear. See Shifting Out of Park
(Automatic Transmission) on page 3-32.
