5. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare
tire to t.
6. Remove all the wheel nuts and take off the at tire.
{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.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
5-77

8. Place the spare on the wheel-mounting surface.
{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.
9. Put the nuts on by
hand. Make sure the
rounded end is
toward the wheel.
10. Tighten each nut by hand until the wheel is held
against the hub. If a nut can’t be turned by hand,
use the wheel wrench and see your dealer as soon
as possible.11. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.

2. If visible, rst try to tighten the cable by turning the
wheel wrench clockwise until you hear two clicks or
feel it skip twice. You cannot overtighten the cable.
3. Loosen the cable by turning the wheel wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times.
If the spare tire lowers to the ground, continue with
Step 2 ofRemoving the Spare Tire and Tools on
page 5-72.
5. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable is exposed.
6. Attach the jack handle, extension(s) and the wheel
wrench to the jack and place it under the vehicle
towards the front of the rear bumper. Position
the center lift point of the jack under the center of
the spare tire.
7. Turn the wrench clockwise to raise the jack until it
lifts the end tting.
8. Continue raising the jack until the spare tire stops
moving upward and is held rmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.
5-81

{CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing up. If the
spare tire is stored with the valve stem
pointing downward, its secondary latch won’t
work properly and the spare tire could loosen
and suddenly fall from your vehicle. If this
happened when your vehicle was being driven,
the tire might contact a person or another
vehicle, causing injury and, of course, damage
to itself as well. Be sure the
underbody-mounted spare tire is stored with
its valve stem pointing up.
Notice:An aluminum wheel with a at tire should
always be stored under the vehicle with the
hoist. However, storing it that way for an extended
period could damage the wheel. To avoid this,
always stow the wheel properly with the valve stem
pointing up and have the wheel repaired as soon
as possible.Follow this diagram to store the underbody-mounted
spare.
A. Wheel Wrench
B. Hoist Shaft
C. Extension(s)
D. Retainer
E. Spare or Flat Tire
(Valve Stem
Pointed Up)
1. Put the tire on the ground at the rear of the vehicle,
with the valve stem pointed up and to the rear.
2. Pull the retainer (D) through the wheel.
3. Put the socket end of the extension (C), on an
45 degree angle downward, through the hole in
the rear bumper and into the hoist shaft (B).
4. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench (A)
clockwise until you hear two clicks or feel it
skip twice. This indicates that the tire is secure and
the cable is tight. The spare tire hoist cannot be
overtightened.

Care of Safety Belts
Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate
protection. Clean safety belts only with mild
soap and lukewarm water.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather frequent application may be required. See
Recommended Fluids and Lubricants on page 6-12.
Washing Your Vehicle
The paint nish on the vehicle provides beauty, depth of
color, gloss retention, and durability.
The best way to preserve the vehicle’s nish is to keep it
clean by washing it often with lukewarm or cold water.
Do not wash the vehicle in the direct rays of the sun. Use
a car washing soap. Do not use strong soaps or chemical
detergents. Be sure to rinse the vehicle well, removing all
soap residue completely. GM-approved cleaning
products can be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 5-94. Do not use
cleaning agents that are petroleum based, or that contain
acid or abrasives. All cleaning agents should be ushed
promptly and not allowed to dry on the surface, or they
could stain. Dry the nish with a soft, clean chamois or an
all-cotton towel to avoid surface scratches and
water spotting.
High pressure car washes may cause water to enter
the vehicle.
5-89

Windshield, Backglass, and Wiper
Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade or
windshield.
Clean the outside of the windshield with a full-strength
glass cleaning liquid. The windshield is clean if beads do
not form when you rinse it with water.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by
wiping vigorously with a cloth soaked in full-strength
windshield washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Aluminum Wheels
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or cleaners
that contain acid on aluminum or chrome-plated
wheels, you could damage the surface of the
wheel(s). The repairs would not be covered by your
warranty. Use only GM-approved cleaners on
aluminum or chrome-plated wheels.
Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may then
be applied.
Notice:Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not
be covered by your warranty. Use chrome polish on
chrome wheels only.

(c)Visually inspect hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
ttings and clamps; replace with genuine GM parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(e)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
(The airbag system does not need regular maintenance.)
(f)Lubricate all key lock cylinders, hood latch assembly,
secondary latch, pivots, spring anchor, release pawl,
rear compartment hinges, outer liftgate handle pivot
points, rear door detent link, roller mechanism, liftgate
handle pivot points, latch bolt, fuel door hinge, cargo
door hinge, locks and folding seat hardware. More
frequent lubrication may be required when exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better and not stick or squeak.(g)Check vent hose at transfer case for kinks and
proper installation.
(h)Change automatic transmission uid and lter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
(i)Drain, ush and rell cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-25 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap and ller neck. Pressure test the cooling
system and pressure cap.
(j)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the uid level checked. Add uid if needed.
(k)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.
