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.
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.

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.
