{WARNING
Rust or dirt on a wheel, or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. When
you change a wheel, remove
any rust or dirt from 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.Tightening Wheel Lug Nuts
{WARNING
Never use oil or grease on studs
or the threads of the wheel nuts.
If you do, the wheel nuts might
come loose and the wheel could
fall off, causing a crash.
{WARNING
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead
to a crash. Be sure to use the
correct wheel nuts. If you have
to replace them, be sure to get
new GM original equipment
wheel nuts. Notice:
Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage.
To avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification.
Tighten the wheel lug nuts firmly in
a crisscross sequence as shown.

Vehicle Care 10-87
Do not wash the vehicle in direct
sunlight. Use a car washing soap.
Do not use cleaning agents that
are petroleum based or that contain
acid or abrasives, as they can
damage the paint, metal or plastic
on the vehicle. Approved cleaning
products can be obtained from your
dealer. Follow all manufacturers'
directions regarding correct
product usage, necessary safety
precautions and appropriate
disposal of any vehicle care
product.
Rinse the vehicle well, before
washing and after to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.Notice:
If you drive the vehicle
through an automatic car wash
that does not have enough
clearance for the wide rear tires
and wheels, you could damage
the vehicle. Verify with the
manager of the car wash that the
vehicle will fit before entering the
car wash or use a touchless
car wash.
High pressure car washes may
cause water to enter the vehicle.
Avoid using high pressure washes
closer than 12 inches (30 cm) to
the surface of the vehicle. Use of
power washers exceeding 1,200 psi
(8 274 kPa) can result in damage or
removal of paint and decals.
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 under “Washing
the Vehicle”.
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.
If 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.
Notice: Machine compounding
or aggressive polishing on a
basecoat/clearcoat paint finish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint finish on the
vehicle.
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

10-90 Vehicle Care
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, we will repair, at no
charge to the owner, the surfaces
of new vehicles damaged by this
fallout condition within 12 months
or 20 000 km (12,000 miles) of
purchase, whichever occurs first.
Interior Care
The vehicle's interior will continue to
look its best if it is cleaned often.
Although not always visible, dust
and dirt can accumulate on the
upholstery. Dirt can damage
carpet, fabric, leather, and plastic
surfaces. Regular vacuuming isrecommended to remove particles
from the upholstery. It is important to
keep the upholstery from becoming
and remaining heavily soiled. Soils
should be removed as quickly as
possible. The 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 home
furnishings may also transfer color
to the vehicle's interior.
When cleaning the 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:
Using abrasive cleaners
when cleaning glass surfaces on
the vehicle, could scratch the
glass and/or cause damage to
the rear window defogger. When
cleaning the glass on the vehicle,
use only a soft cloth and glass
cleaner.
Many cleaners contain solvents that
may become concentrated in the
vehicle's breathing space. Before
using cleaners, read and adhere to
all safety instructions on the label.
While cleaning the vehicle's interior,
maintain adequate ventilation by
opening the vehicle's doors and
windows.
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Products that remove odors from
the vehicle's upholstery and clean
the vehicle's glass can be obtained
from your dealer.

Vehicle Care 10-91
Do not clean the vehicle using:
.A knife or any other sharp object
to remove a soil from any interior
surface.
.A stiff brush. It can cause
damage to the vehicle's interior
surfaces.
.Heavy pressure or aggressive
rubbing with a cleaning cloth.
Use of heavy pressure can
damage the interior and does
not improve the effectiveness
of soil removal.
.Laundry detergents or
dishwashing soaps with
degreasers can leave residue
that streaks and attracts dirt.
For liquid cleaners, about
20 drops per gallon (3.78 L) of
water is a good guide. Use only
mild, neutral-pH soaps.
.Too much cleaner that saturates
the upholstery.
.Organic solvents such as
naptha, alcohol, etc. that can
damage the vehicle's interior.
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 any soil, always try to remove it
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:
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.

Coated Moldings
These moldings are around the
hatch opening in the rear area.
.When lightly soiled, wipe with a
sponge or soft lint-free cloth
dampened with water.
.When heavily soiled, use warm
soapy water.
Leather
A soft cloth dampened with water
can 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 topreserve and protect leather
may permanently change the
appearance and feel of the leather
and are not recommended. Do not
use silicone or wax-based products,
or those containing organic
solvents to clean the vehicle's
interior because they can alter the
appearance by increasing the gloss
in a non-uniform manner. Never use
shoe polish on leather.Instrument Panel, Vinyl and
other Plastic Surfaces
A soft cloth dampened with water
may be used to remove dust.
If a more thorough cleaning is
necessary, a clean soft cloth
dampened with a mild soap solution
can be used to gently remove
dust and dirt. Never use spot lifters
or removers on plastic surfaces.
Many commercial cleaners and
coatings that are sold to preserveand protect soft plastic surfaces
may permanently change the
appearance and feel of the interior
and are not recommended. Do not
use silicone or wax-based products,
or those containing organic solvents
to clean the vehicle's interior
because they can alter the
appearance by increasing the
gloss in a non-uniform manner.
Some commercial products may
increase gloss on the instrument
panel. The increase in gloss may
cause annoying reflections in the
windshield and even make it difficult
to see through the windshield under
certain conditions.
Cargo Cover and
Convenience Net
Wash with warm water and mild
detergent, rinse with cold water
and tumble dry on low. Do not use
chlorine bleach.
