1997 PONTIAC GRAND AM open hood

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.
A 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 Pontiac dealer in the area where you’ll be parking
your vehicle. The dealer can give you the best advice for
that particular area.

Low Coolant Warning Light
If this light comes on and
stays on, the vehicle should
be promptly pulled off the
road and the coolant level
checked. See “Engine
Coolant” in the Index.
If there are visible signs of steam see “Engine
Overheating” in the Index before opening the hood.
Malfunction Indicator Lamp
(Check Engine Light)
Your Pontiac is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
CHECK
ENGINE
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) The CHECK
ENGINE light
comes on
to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle.
This
system is also designed to assist your service technician
in correctly diagnosing
any malfunction.

2. Get the vehicles close 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).
3. Turn off the ignition on both vehicles, Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn off all lamps that aren’t needed as well
as radios. This will avoid sparks and help save both
batteries. In addition,
it could save your radio!
I NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
A CAUTION:
I -i
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
‘4. Open the hoods and locate the batteries. Find the
positive
(+) and negative (-) terminals on each battery.

Engine Overheating
You will find a coolant temperature gage and a low
coolant warning light on your Pontiac’s instrument
panel. See “Engine Coolant Temperature Gage”
and
“Low Coolant Warning Light” in the Index.
If Steam Is Coming From Your Engine
A CAUTION:
I
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before
you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire.
You or
others could be badly burned. Stop your engine
if
it overheats, and get out of the vehicle until the
engine is cool.
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be covered
by your warranty.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@) or
DRIVE (D) for automatic transaxles.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 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.
