Engine Coolant Heater (Option)
In very cold weather, 0 OF (- 1 8 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 1 10-volt outlet.
NOTICE:
After you’ve used the coolant heater, be sure to
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 weather, the kind
of oil
you have, and some other things. Instead
of trying to list
everything here, we
ask that you contact your Pontiac
dealer in the area where you’ll
be parking your vehicle.
The dealer can give
you the best advice for that
particular area.

2.
3.
Get the vehicles cbse enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your Pontiac, and the bad grounding could
damage the electrical systems.
You could be injured
if the vehicles roll. Set the
parking brake firmly on each vehicle. Put an
automatic transaxle
in PARK (P) or a manual
transaxle in NEUTRAL
(N).
Turn off the ignition on both vehicles. Turn off all
lamps that aren’t needed, and radios. This will avoid
sparks and help save both batteries. And it could
save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged.
The repairs wouldn’t be covered by
your warranty.
4.. Open the hoods and locate the batteries.
5. Find the positive (+) and negative (-) terminals on
each battery. Your Pontiac has a remote positive
(+)
jump starting terminal. The terminal is on the same
side
of the engine compartment as your battery. You
should always use the remote positive (+) terminal
instead
of the positive (+) terminal on your battery.
To uncover the remote positive (+) terminal, lift the
red plastic cap.

If you get the overheat warning with no sign of steam,
try this for
a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
3. If you’re in a traffic jam, shift to NEUTRAL (N);
speed and open the window as necessary.
otherwise, shift to the highest gear while
driving
-- DRIVE (D) or THIRD (3).
If you no longer have the overheat warning, you can
drive.
Just to be safe, drive slower for about ten minutes.
If the warning doesn’t come back on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning,
turn ofSthe engine and get everyone out
of the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.

Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center.
An electrical overload
will cause the lamps
to go on and off, or in some cases
to remain
off. If this happens, have your headlamp
system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse.
If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed.
