Engine Coolant Heater (Option)
In very cold weather, 0°F
(- 18 O C) or colder, the
engine coolant heater
can help.
You’ll get easier starting and better fuel economy during
engine warm-up. Usually, the coolant heater should be
plugged in a minimum of four hours prior
to starting
your vehicle.
To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
-
/! CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire.
You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt AC outlet.
If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.

4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine
parts. If you don’t, it could be damaged.
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
GM 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.
