Chevrolet 1998 Tracker Owner's Manual page 87

It can be 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've 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 ) .
If you
have four-wheel drive and your transfer
case is
in NEUTRAL (N), your vehicle will be free to roll,
even if your shift lever
is
in
PARK (P). So, be sure the
transfer case is in
a
drive gear
--
not in NEUTRAL (N).
Always set your parking brake. Follow the proper steps
to be sure your vehicle won't move. See "Shifting Into
PARK (P)" in the Index.
If you're pulling
a trailer, see "Towing
a Trailer" in
the Index.
