Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See the
warranty manual for information
regarding the tire warranty and
where to get service. For
additional information refer to the
tire manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much flexing.
There could be a blowout
and a serious crash. See
Vehicle Load Limits 0191.

302 VEHICLE CARE
If using an automatic car wash, follow
the car wash instructions. The
windshield wiper and rear window
wiper, if equipped, must be off.
Remove any accessories that may be
damaged or interfere with the car
wash equipment.
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.
Finish Care
Application of aftermarket clearcoat
sealant/wax materials is not
recommended. If painted surfaces are
damaged, see your dealer to have the
damage assessed and repaired. 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, usenon-abrasive cleaners that are marked
safe for painted surfaces to remove
foreign matter.
Occasional hand waxing or mild
polishing should be done to remove
residue from the paint finish. See your
dealer for approved cleaning products.
Do not apply waxes or polishes to
uncoated plastic, vinyl, rubber, decals,
simulated wood, or flat paint as
damage can occur.
Caution
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.
To keep the paint finish looking new,
keep the vehicle garaged or covered
whenever possible. Protecting Exterior Bright Metal
Moldings
Caution
Failure to clean and protect the
bright metal moldings can result in
a hazy white finish or pitting. This
damage would not be covered by
the vehicle warranty.
The bright metal moldings on the
vehicle are aluminum, chrome,
or stainless steel. To prevent damage,
always follow these cleaning
instructions:
. Be sure the molding is cool to the
touch before applying any cleaning
solution.
. Use only approved cleaning
solutions for aluminum, chrome,
or stainless steel. Some cleaners
are highly acidic or contain
alkaline substances and can
damage the moldings.
. Always dilute a concentrated
cleaner according to the
manufacturer’s instructions.

306 VEHICLE CARE
Before using cleaners, read and follow
all safety instructions on the label.
While cleaning the interior, open the
doors and windows to get proper
ventilation.
To prevent damage, do not clean the
interior using the following cleaners
or techniques:
.Never use a razor or any other
sharp object to remove soil from
any interior surface.
. Never use a brush with stiff
bristles.
. Never rub any surface aggressively
or with too much pressure.
. Do not use laundry detergents or
dishwashing soaps with
degreasers. For liquid cleaners, use
approximately 20 drops per 3.8 L
(1 gal) of water. A concentrated
soap solution will create streaks
and attract dirt. Do not use
solutions that contain strong or
caustic soap.
. Do not heavily saturate the
upholstery when cleaning. .
Do not use solvents or cleaners
containing solvents.
Interior Glass
To clean, use a terry cloth fabric
dampened with water. Wipe droplets
left behind with a clean dry cloth.
If necessary, use a commercial glass
cleaner after cleaning with plain water.
Caution
To prevent scratching, never use
abrasive cleaners on automotive
glass. Abrasive cleaners or
aggressive cleaning may damage
the rear window defogger.
Cleaning the windshield with water
during the first three to six months of
ownership will reduce tendency to fog.
Speaker Covers
Vacuum around a speaker cover
gently, so that the speaker will not be
damaged. Clean spots with water and
mild soap.
Coated Moldings
Coated moldings should be cleaned.
. When lightly soiled, wipe with a
sponge or soft, lint-free cloth
dampened with water.
. When heavily soiled, use warm
soapy water.
Fabric/Carpet/Suede
Start by vacuuming the surface using
a soft brush attachment. If a rotating
vacuum brush attachment is being
used, only use it on the floor carpet.
Before cleaning, gently remove as
much of the soil as possible:
.Gently blot liquids with a paper
towel. Continue blotting until no
more soil can be removed.
. For solid soils, remove as much as
possible prior to vacuuming.
To clean: 1. Saturate a clean, lint-free colorfast cloth with water.
Microfiber cloth is recommended
to prevent lint transfer to the
fabric or carpet.

VEHICLE CARE 307
2. Remove excess moisture bygently wringing until water does
not drip from the cleaning cloth.
3. Start on the outside edge of the soil and gently rub toward the
center. Fold the cleaning cloth to
a clean area frequently to
prevent forcing the soil in to the
fabric.
4. Continue gently rubbing the soiled area until there is no
longer any color transfer from
the soil to the cleaning cloth.
5. If the soil is not completely removed, use a mild soap
solution followed only by plain
water.
If the soil is not completely removed,
it may be necessary to use a
commercial upholstery cleaner or spot
lifter. Test a small hidden area for
colorfastness before using a
commercial upholstery cleaner or spot
lifter. If ring formation occurs, clean
the entire fabric or carpet.
After cleaning, use a paper towel to
blot excess moisture.Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays
Use a microfiber cloth on high gloss
surfaces or vehicle displays. First, use
a soft bristle brush to remove dirt that
can scratch the surface. Then gently
clean by rubbing with a microfiber
cloth. Never use window cleaners or
solvents. Periodically hand wash the
microfiber cloth separately, using mild
soap. Do not use bleach or fabric
softener. Rinse thoroughly and air dry
before next use.
Caution
Do not attach a device with a
suction cup to the display. This may
cause damage and would not be
covered by the vehicle warranty.
Instrument Panel, Leather, Vinyl,
Other Plastic Surfaces, Low
Gloss Paint Surfaces, and
Natural Open Pore Wood
Surfaces
Use a soft microfiber cloth dampened
with water to remove dust and loose
dirt. For a more thorough cleaning,
use a soft microfiber cloth dampened
with a mild soap solution.
Caution
Soaking or saturating leather,
especially perforated leather, as well
as other interior surfaces, may
cause permanent damage. Wipe
excess moisture from these surfaces
after cleaning and allow them to
dry naturally. Never use heat,
steam, or spot removers. Do not use
cleaners that contain silicone or
wax-based products. Cleaners
containing these solvents can
permanently change the appearance
and feel of leather or soft trim, and
are not recommended.

Footnotes—Maintenance Schedule
Additional Required Services -
Normal
(1) Vehicles with different size front
and rear tires do not have tire
rotation. See Tire Rotation0284.
(2) Or every two years, whichever
comes first. More frequent passenger
compartment air filter replacement
may be needed if driving in areas with
heavy traffic, poor air quality, high
dust levels, or environmental
allergens. Passenger compartment air
filter replacement may also be needed
if there is reduced airf low, window
fogging, or odors. Your GM dealer can
help determine when to replace the
filter. (3)
Visually check all fuel and vapor
lines and hoses for proper attachment,
connection, routing, and condition.
(4) Or every two years, whichever
comes first. If driving in dusty
conditions, inspect the filter at each
oil change or more often as needed.
(5) Or every five years, whichever
comes first. See Cooling System0255.
(6) Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate
the transfer case fluid. Contaminated
fluid will decrease the life of the
transfer case and/or axles and should
be replaced. (7)
Or every 10 years, whichever
comes first. Inspect for fraying,
excessive cracking, or damage; replace,
if needed.
(8) Replace brake fluid every five
years. See Brake Fluid 0262.
