Chevrolet 2008 Optra Owner's Manual page 95

Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. The regular
brakes must be applied before you can shift from
PARK (P) when the ignition key is in ON/RUN. If you
cannot shift out of PARK (P) while holding the brake
pedal down, see Shifting Out of PARK (P) on page 2-30.
REVERSE (R): Use this gear to back up.
When shifting from NEUTRAL (N) to REVERSE (R),
you must press down on the shift lever while shifting.
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 the transmission, see
If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-17.
NEUTRAL (N): In this position, the engine does not
connect with the wheels. To restart while you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
CAUTION:
{
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is firmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice: Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
DRIVE (D): This position is for normal driving.
Notice: If your vehicle seems to start up rather
slowly or not shift gears when you go faster, and
you continue to drive your vehicle that way, you
could damage the transmission. Have your vehicle
serviced right away.
