Chevrolet 1999 S10 Pickup Owner's Manual page 77

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.
Don't 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 won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
See "Shifting Into PARK (P)" in the Index.
If you're pulling a trailer, see "Towing a Trailer"
in the Index.
Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has a
-
Brake Transmission Shift Interlock (BTSI). You have
to fully apply your regular brakes before you can shift
from PARK (P) when the ignition key is in RUN. If you
cannot shift out of PARK (P), ease pressure on the shift
--
lever push the shift lever all the way into PARK (P) as
you maintain brake application. Then move the shift
lever into the gear you wish. See "Shifting Out of
PARK (P)" in the Index.
REVERSE (R): Use this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle
is moving forward could damage your
transmission. 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
"Stuck In Sand, Mud, Ice or Snow" in the Index.
