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 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 in
the jump start procedure. Put an automatic transaxle
in PARK (P) or a manual transaxle in NEUTRAL
before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. 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!
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. Find the
positive (+) and negative (
-) terminals on each battery.
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.

5. Your vehicle has a
remote positive (+)
jump starting terminal.
The terminal is under a
tethered cap at the front
of the underhood fuse
and relay center. See
ªEngine Compartment
Overviewº in the Index
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.
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.

5-6
CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
6. Check that the jumper cables don't have loose or
missing insulation. If they do, you could get a shock.
The vehicles could be damaged, too.
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 engine part or a body metal surface.
Don't connect positive (+) to negative (
-) or you will
get a short that would damage the battery and maybe
other parts, too. And don't connect negative (
-)
to negative (
-) on the dead battery, as this can
cause sparks.7. Connect the red positive (+) cable to the positive (+)
terminal of the vehicle with the dead battery. Use a
remote positive (+) terminal if the vehicle has one.
8. Don't let the other end
touch metal. Connect it
to the positive (+)
terminal of the good
battery. Use a remote
positive (+) terminal if
the vehicle has one.

5-7
9. Now connect the
black negative (
-) cable
to the good battery's
negative (
-) terminal.
Don't let the other end 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.
10. Attach the cable at least
18 inches (45 cm) away
from the dead battery,
but not near engine
parts that move.
The electrical connection is just as good there, but the
chance of sparks getting back to the battery is much less.
11. Now start the vehicle with the good battery and
run the engine for a while.
12. Try to start the vehicle with the dead battery.
If it won't start after a few tries, it probably
needs service.

5-8
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.
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº and ªRecreational Vehicle Towingº in
the Index.

5-9
Engine Overheating
You will find an engine coolant temperature gage on
the instrument panel cluster. See ªEngine Coolant
Temperature Gageº in the Index. You also have an
engine coolant temperature warning message on the
instrument panel cluster. See ªEngine Coolant
Temperature Warning Messageº in the Index.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle
to be driven to a safe place in an emergency situation.
Should an overheated engine condition exist, an
overheat protection mode which alternates firing groups
of cylinders helps prevent engine damage. In this mode,
you will notice a significant loss in power and engine
performance. The temperature gage will indicate an
overheat condition exists. Towing a trailer in the
overheat protection mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss and change the oil.
See ªEngine Oilº in the Index.

5-10 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. See ªOverheated Engine
Protection Operating Modeº in the Index.

5-11
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 ªOverheated
Engine Protection Operating Modeº in the Index.
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 ªOverheated
Engine Protection Operating Modeº listed previously in
this section.
You may decide not to lift the hood but to get service
help right away.

5-12
Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
A. Radiator Pressure Cap
B. Electric Engine Cooling Fans
C. Coolant Recovery Tank
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 recovery tank is boiling,
don't do anything else until it cools down.

5-13
When the engine is cold, the coolant level should be at
or above the FULL COLD mark. If it isn't, you may
have a leak in the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cooling system.
CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them.
If you do, you can be burned.
Don't run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
See ªOverheated Engine Protection Operating
Modeº in the Index.
