1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
NOTICE:
If the other system isn't a 12-volt system with a
negative ground, both vehicles can be damaged.
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 vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved.
Put an automatic transaxle in PARK (P) and a
manual transaxle in NEUTRAL before setting the
parking brake.2. 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 the radios. This will avoid sparks and help save
both batteries. In addition, it could save the radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.

3. Open the hoods and locate the batteries. You'll also
need to open the power distribution fuse block cover
to access the positive (+) terminal on the battery
(see arrow).
CAUTION:
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.
CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight
if you need more light.
Be sure the battery has enough water. You don't
need to add water to the ACDelco battery
installed in every new GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take
care of that first. If you don't, explosive gas could
be present.
Battery fluid contains acid that can burn you.
Don't get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.

4. Check that the jumper cables don't have loose or
missing insulation. If they do, you could get a shock.
The vehicles could also be damaged.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go
to positive (+) and negative (
-) will go to a heavy,
unpainted metal part on the engine of the vehicle
with the dead battery. Don't connect positive (+) to
negative (
-) or you will get a short that would
damage the battery and maybe other parts, too.
Also, don't connect negative (
-) to negative (-).
CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Connect the red positive (+) cable to the positive (+)
terminal of the vehicle with the dead battery.

6. Don't let the other
end of the positive
cable touch metal.
Connect it to the
positive (+) terminal
of the good battery.
Now connect the
negative (
-) cable to
the good battery's
negative (
-) terminal.Don't let the other end of the negative (
-) cable
touch anything until the next step. The other end of
the negative (
-) cable doesn't go to the dead battery.
It goes to a heavy unpainted metal part on the engine
of the vehicle with the dead battery.
7. Attach the cable at least 18 inches (45 cm) away from
the dead battery, but not near engine parts that move.
A good spot to attach the
negative (
-) cable is on
the bracket between the
engine coolant surge tank
and the engine block.
8. Now start the vehicle with the good battery and run
the engine for a while.
9. Try to start the vehicle with the dead battery.
If it won't start after a few tries, it probably
needs service.

10. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don't touch
each other or any other metal.
Jumper Cable Removal
A. Heavy, Unpainted Metal Engine Part
B. Good Battery
C. Dead BatteryTo disconnect the jumper cables from both vehicles,
do the following:
1. Disconnect the black negative (
-) cable from the
heavy, unpainted metal engine part on the vehicle
that had the dead battery.
2. Disconnect the black negative (
-) cable from
the negative (
-) terminal on the vehicle with the
good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
When a power loss occurs, there are steps that
must be followed to calibrate the Electronic Throttle
Control (ETC). If these steps are not done, the
engine will not run properly. For information
regarding these steps, see ªBatteryº in the Index.
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.

Engine Overheating
You will find the warning light about a hot engine on the
instrument panel.
If Steam Is Coming From Your Engine
CAUTION:
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.

5-10 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. Dial temperature control to the highest heat setting
and open the windows, as necessary.
3. If you're in a traffic jam, shift to NEUTRAL (N);
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
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.
You may decide not to lift the hood but to get service
help right away.

Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
A. Coolant Surge Tank with Pressure Cap
B. Electric Engine Fans
CAUTION:
An electric engine cooling fan under the hood 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.
If the coolant inside the coolant surge tank is boiling,
don't do anything else until it cools down.
