Saturn 2009 ASTRA - Manual (Page 152)

Automatic Transmission
Operation
If the vehicle has an automatic
transmission, the shift lever
is located on the console between
the seats.
The vehicle may also have an
electronic shift position indicator that
displays the position of the shift
lever. This indicator is located above
the trip odometer on the instrument
panel cluster.
P (Park): This position locks the
front wheels. It is the best position to
use when the engine is started
because the vehicle cannot move
easily.
{ CAUTION
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 on page 8-11.
Make sure the shift lever is fully in
P (Park) before starting the
engine. The vehicle has an
automatic transmission shift lock
control system. The regular brakes
must be applied before you can
shift from P (Park) when the ignition
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 8-12.
R (Reverse): Use this gear to
back up.
Notice: 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 Rocking Your Vehicle to Get
It Out on page 8-29.
