Pontiac G3 2010 Owner's Manual page 127

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 29.
Ensure that the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to
apply the brake pedal before you can shift from P (Park)
when the key is in ON/RUN. If you cannot shift out of
P (Park) while holding the brake pedal down, see
Shifting Out of Park on page 3 30.
R (Reverse) : Use this gear to back up.
When shifting from N (Neutral) to R (Reverse), you need
to apply the brake pedal and push the release button on
the front of the shifter.
Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice or sand without damaging the transmission, see If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 5 13.
N (Neutral) : In this position, the engine does not
connect with the wheels. To restart the engine while the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
