The terminal is located
under a tethered cap
at the front of the
underhood fuse block.
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:
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.

5-17 How to Add Coolant to the Radiator
1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise until
it first stops. (Don't press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop.
A hiss means there is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.
The following steps will tell you how to use the jack and
change a tire.

The tools you'll be using include the jack (A),
extension (B) and folding wrench (C).
The compact spare tire is located under the vehicle,
ahead of the rear bumper. See ªCompact Spare Tireº
later in this section for more information about the
compact spare. To remove the compact spare tire,
do the following:A. Hoist Shaft
B. Hoist Assembly
C. Retainer
D. Compact Spare TireE. Extension
(Chisel End)
F. Folding Wrench
1. Attach the folding wrench to the extension and insert
the chisel end on an angle through the hole in the
rear bumper and into the hoist shaft.
2. Turn the folding wrench counterclockwise to lower
the compact spare tire to the ground. Continue to
turn the wrench so the compact spare tire can be
pulled out from under the vehicle.

3. To remove the compact spare tire from the cable, tilt
the retainer at the end of the cable so it can be pulled
up through the wheel opening.4. If your vehicle is an all
-wheel-drive vehicle, after
removing the compact spare tire, turn the wrench
clockwise to raise the cable back up.
On an AWD vehicle, you can not store a full
-size
tire under the vehicle. It should be stowed inside
the vehicle by the cable provided. See ªStoring the
Flat Tire on an All
-Wheel-Drive Vehicleº later in
this section.
If you have a front
-wheel-drive vehicle, the hoist
is used to store a full
-size or a flat road tire under the
vehicle. See ªStoring the Spare Tire and Toolsº and
ªStoring the Flat Tire on a Front
-Wheel-Drive
Vehicleº later in this section.
If the compact spare tire will not lower, check under the
vehicle to see if the tire is hanging loose and the cable
end and spring under the wheel plate are missing. If so,
the secondary latch system is engaged. See ªSecondary
Latch Systemº later in this section.
To continue changing the flat tire see ªRemoving
the Flat Tire and Installing the Spare Tireº later in
this section.

1. Place the jack under the vehicle, ahead of the rear
bumper. Position the center lift point of the jack
under the center of the compact spare tire.
2. Turn the folding wrench clockwise to raise the jack
until it lifts the secondary latch devise under the
wheel plate.
3. Keep raising the jack until the compact spare tire
stops moving upward and is held firmly in place, this
lets you know that the secondary latch has released.4. Lower the jack by turning the folding wrench
counterclockwise. Keep lowering the jack until the
compact spare tire is resting on the folding wrench.
5. Grasp the compact spare tire with both hands and
pull it out from under the vehicle.
6. Reach under the vehicle and remove the folding
wrench and jack.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or flat tire using the
hoist assembly until it has been repaired or replaced.

5-28 Removing the Flat Tire and Installing
the Spare Tire
1. Loosen the wheel
nuts
-- but do
not remove
them
-- using the
folding wrench.
(Turn the handle about 180 degrees, then flip the
handle back to the starting position. This avoids
taking the wrench off the lug nut for each turn.)
For wheels with a wheel lock key, use the wheel lock
key between the lock nut and folding wrench. The
key is supplied in the front passenger door pocket.
NOTICE:
To help avoid damage to the lock nut or the
wheel lock key, do not use an impact wrench
with this key.

3. Attach the folding
wrench to the jack,
and turn the wrench
clockwise to raise the
jack head a few inches.
4. Raise the vehicle by turning the folding wrench
clockwise in the jack. Raise the vehicle far enough
off the ground so there is enough room for the
compact spare tire to fit.
5. Remove all the wheel nuts and take off the flat tire.
6. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.
