Chevrolet 1996 Tahoe Owner's Manual page 89

A
CAUTION:
A
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.
