Engine Coolant Heater
Your vehicle may have an engine coolant heater. In very
cold weather,
0°F (-1 8°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
prior to starting your vehicle. At temperatures above
32°F (OOC), use of the coolant heater is not required.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the eieciricai cord.
The electrical cord is located on the driver’s side
of the engine compartment.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
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
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label),
it is designed to operate on fuels that meet California
specifications. If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on (see
Malfunction Indicator Lamp on page 3-47 )
and your vehicle may fail a smog-check test. If this
occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work properly.
You should not have to add anything to your fuel. Gasolines containing
oxygenates, such as ethers and
ethanol, and reformulated gasolines may be available in
your area to contribute to clean air. General Motors
recommends that you use these gasolines, particularly
if they comply with the specifications described earlier.
Notice: Your vehicle was not designed for fuel
that contains methanol. Don’t use fuel containing
methanol.
It can corrode metal parts in your fuel
system and also damage the plastic and rubber
parts. That damage wouldn’t be covered under
your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors does
not recommend the use of such gasolines. Fuels
containing MMT can reduce the life of spark plugs and
the performance of the emission control system may
be affected. The malfunction indicator lamp may turn on.
If this occurs, return to your authorized GM dealer
for service.

Checking Things Under
the Hood Hood Release
To open the hood, do the following:
I
A'CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing and tools away
from any underhood electric fan.
1
L
Things that burn can get on hot engine parts
and start
a fire. These include liquids like fuel,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that
will burn onto a hot engine.
1. Pull the hood release handle, located on the
driver's side under the instrument panel.
2. Go to the front of the vehicle and push up on the
underhood release, located near the center under
the grille.

If Steam Is Coming From Your Engine
Steam fr n a rheated engine 4 urn
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.
See “Overheated Engine Protection Operating
Mode”
in the Index for information on driving
to a safe place
in an emergency.
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. See “Overheated Engine Protection
Operating Mode”
in the Index for information on
driving to a safe place in an emergency.

If No Steam Is Coming From
Your Engine
If you get an engine 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:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. If your air conditioner is on, 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 (D) or
THIRD
(3).
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, idle the engine for
three minutes while you’re parked. If you still have the
warning,
turn off the engine and get everyone out of
the vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to
lift the hood but to get service
help right away.

Notice: If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
3.
4.
Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlet. Turn
off
the radio and all lamps that aren’t needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
Open the hoods and locate the batteries. Find the
positive
(+) and negative (-) terminal locations on
each vehicle.
You will not need to access your battery for jump
starting. Your vehicle has a remote positive
(+)
jump starting terminal for that purpose. The terminal is located
under a tethered cap at
the front of the underhood
fuse block. See
Engine
Compartment Overview
on page
5- 12 for more
information on location.
Squeeze the tabs and pull up
on the cap to access
the remote positive
(+) terminal. You should always
use the remote positive
(+) terminal instead of the
positive (+) terminal on your battery.
An electric fan can start up ever !hen the
engine is not running and can injure you.
Keep hands, clothing and tools away from any
underhood electric fan.
