{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 will not 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 at or spare tire.
A. Wheel Wrench
B. Hoist Shaft
C. Extension
D. Retainer
E. Spare or Flat Tire
(Valve Stem
Pointed Up)
1. Put the tire (E) on the ground at the rear of
the vehicle.
2. Remove the hubcap, if the vehicle has one,
from the at tire by tapping the backside of
the hubcap with the wheel wrench (A). Store in
a safe location until the at tire is repaired.
Once the tire is repaired, replace the hubcap.

Do not clean your vehicle using the following
cleaners or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
Never apply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior and
does not improve the effectiveness of soil
removal.
Use only mild, neutral-pH soaps. Avoid
laundry detergents or dishwashing soaps with
degreasers. Using too much soap will leave
a residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result
from the use of many organic solvents such
as naptha, alcohol, etc.
Fabric/Carpet
Use a vacuum cleaner with a soft brush
attachment frequently to remove dust and loose
dirt. A canister vacuum with a beater bar in
the nozzle may only be used on oor carpet and
carpeted oor mats. For soils, always try to remove
them rst with plain water or club soda. Before
cleaning, gently remove as much of the soil
as possible using one of the following techniques:
For liquids: gently blot the remaining soil
with a paper towel. Allow the soil to absorb
into the paper towel until no more can
be removed.
For solid dry soils: remove as much as
possible and then vacuum.
To clean, use the following instructions:
1. Saturate a lint-free, clean white cloth with
water or club soda.
2. Wring the cloth to remove excess moisture.
483

3. Start on the outside edge of the soil and
gently rub toward the center. Continue
cleaning, using a clean area of the cloth
each time it becomes soiled.
4. Continue to gently rub the soiled area until
the cleaning cloth remains clean.
5. If the soil is not completely removed, use a
mild soap solution and repeat the cleaning
process that was used with plain water.
If any of the soil remains, a commercial fabric
cleaner or spot lifter may be necessary. When a
commercial upholstery cleaner or spot lifter is to be
used, test a small hidden area for colorfastness
rst. If the locally cleaned area gives any
impression that a ring formation may result,
clean the entire surface.
After the cleaning process has been completed,
a paper towel can be used to blot excess moisture
from the fabric or carpet.Leather
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is
necessary, a soft cloth dampened with a mild soap
solution can be used. Allow the leather to dry
naturally. Do not use heat to dry. Never use steam
to clean leather. Never use spot lifters or spot
removers on leather. Many commercial leather
cleaners and coatings that are sold to preserve
and protect leather may permanently change
the appearance and feel of your leather and are
not recommended. Do not use silicone or
wax-based products, or those containing organic
solvents to clean your vehicle’s interior because
they can alter the appearance by increasing
the gloss in a non-uniform manner. Never use
shoe polish on your leather.
484

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. Approved cleaning products can
be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 490.Donot
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.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and
a car washing soap to clean exterior lamps
and lenses. Follow instructions underWashing
Your Vehicle on page 486.
Finish Care
Occasional waxing or mild polishing of your
vehicle by hand may be necessary to remove
residue from the paint nish. You can get
GM-approved cleaning products from your dealer.
SeeVehicle Care/Appearance Materials on
page 490.
If your vehicle has a “basecoat/clearcoat” paint
nish, the clearcoat gives more depth and gloss to
the colored basecoat. Always use waxes and
polishes that are non-abrasive and made for a
basecoat/clearcoat paint nish.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
nish may damage it. Use only non-abrasive
waxes and polishes that are made for a
basecoat/clearcoat paint nish on your vehicle.

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.
The surface of these wheels is similar to the
painted surface of the vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because the surface could
be damaged. Do not use chrome polish on
aluminum wheels.Notice:If you drive your vehicle through an
automatic car wash that has silicone carbide
tire cleaning brushes, you could damage
the aluminum or chrome-plated wheels. The
repairs would not be covered by your warranty.
Never drive a vehicle equipped with aluminum
or chrome-plated wheels through an
automatic car wash that uses silicone carbide
tire cleaning brushes.
Do not take the vehicle through an automatic car
wash that has silicone carbide tire cleaning
brushes. These brushes can also damage the
surface of these wheels.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the
paint nish and/or tires. When applying a tire
dressing, always wipe off any overspray
from all painted surfaces on your vehicle.

(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)Inspect hoses for cracks, chang, leaks, 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

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 405 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.
