{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after 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 needed, to
get all the rust or dirt off.
9. Remove any rust or
dirt from the wheel
bolts, mounting
surfaces and
spare wheel.10. Place the compact spare tire 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.
11. Install the wheel nuts with the rounded end of
the nuts toward the wheel. Tighten each nut
by hand clockwise until the wheel is held
against the hub.
12. Lower the vehicle by turning the wheel
wrench counterclockwise. Lower the jack
completely.

Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its
best if it is cleaned often. Although not always
visible, dust and dirt can accumulate on your
upholstery. Dirt can damage carpet, fabric, leather,
and plastic surfaces. Regular vacuuming is
recommended to remove particles from your
upholstery. It is important to keep your upholstery
from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes of
heat that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and
garments that transfer color to your home
furnishings may also transfer color to your
vehicle’s interior.When cleaning your vehicle’s interior, only use
cleaners specifically designed for the surfaces
being cleaned. Permanent damage may result
from using cleaners on surfaces for which
they were not intended. Use glass cleaner only on
glass. Remove any accidental over-spray from
other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when
cleaning glass surfaces on your vehicle, you
could scratch the glass and/or cause damage
to the integrated radio antenna and the
rear window defogger. When cleaning the
glass on your vehicle, use only a soft cloth and
glass cleaner.
335
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to
all safety instructions on the label. While cleaning
your vehicle’s interior, maintain adequate
ventilation by opening your vehicle’s doors and
windows.
Dust may be removed from small buttons and
knobs using a small brush with soft bristles.
Your dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you
can also obtain a product from your dealer to
remove odors from your vehicle’s upholstery.
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.
336
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 floor carpet and
carpeted floor mats. For soils, always try to remove
them first 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.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
first. 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.
337
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 339.
Finish Care
Occasional waxing or mild polishing of the vehicle
by hand may be necessary to remove residue
from the paint finish. Approved cleaning products
can be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 343.
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.
The vehicle has a basecoat/clearcoat paint
finish. 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 finish.Foreign materials such as calcium chloride and
other salts, ice melting agents, road oil and
tar, tree sap, bird droppings, chemicals from
industrial chimneys, etc., can damage the vehicle’s
finish if they remain on painted surfaces. Wash
the vehicle as soon as possible. If necessary, use
non-abrasive cleaners that are marked safe for
painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging,
weather, and chemical fallout that can take their
toll over a period of years. To help keep the
paint finish looking new, keep the vehicle in a
garage or covered whenever possible.
Windshield 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 glass
cleaning liquid or powder and water solution.
The windshield is clean if beads do not form when
it is rinsed with water.
340
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close
areas of the frame should be loosened before being
flushed. Your dealer or an underbody car washing
system can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can
create a chemical fallout. Airborne pollutants can
fall upon and attack painted surfaces on the
vehicle. This damage can take two forms: blotchy,
ring-shaped discolorations, and small, irregular
dark spots etched into the paint surface.
Although no defect in the paint job causes this, GM
will repair, at no charge to the owner, the surfaces
of new vehicles damaged by this fallout condition
within 12 months or 12,000 miles (20 000 km) of
purchase, whichever occurs first.
