Chevrolet TRACKER 2003 Manual page 85

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
There are several different positions for your shift lever.
It is dangerous to get out
o f
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.
PARK (P): This position locks your rear wheels.
It's
the
best position to use when you start your engine
because your vehicle can't move easily.
