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 1 10-volt AC outlet.
I
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 Chevrolet dealer in the area where you'll be
parking your vehicle. The dealer can give you the best
advice for that particular area.
Automatic Transaxle Operation
Your Chevrolet may be equipped with a three-speed
automatic or
a
four-speed automatic transaxle.
The
shift lever is located on the console between the seats.
There are six different positions for the shift lever on the
three-speed automatic and seven positions for the
four-speed automatic transaxles. While PARK (P),
REVERSE
(R)
and NEUTRAL (N) operate identically
for both transaxles, the forward gear positions represent
different gearing and operation. See "Forward Gears
(3-Speed)" or "Forward-Gears (4-Speed)" later in
this section.
