400 VEHICLE CARE
Hand Wash
Rinse the vehicle well, before and after
washing, 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.
Cleaning Underhood Components
Caution
Do not power wash any component
under the hood that has this
e
symbol.
This could cause damage to the
vehicle that would not be covered
by the vehicle warranty.
Avoid using solvents or abrasive
cleaners that may harm underhood
components. GM recommends using
only water to clean underhood
components.
If using a pressure washer, ensure the
following criteria is met:
.Water pressure must be kept below
14 000 KPa (2,000 PSI).
.Water temperature must be below
80 °C (180 °F).
.A spray nozzle with a 40 degree
wide angle spray pattern or wider
must be used, and must be kept at
least 30 cm (1 ft) away from all
surfaces.
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.
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
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. Occasional hand waxing or mild
polishing should be done to remove
residue from the paint finish. See your
dealer for approved cleaning products.
Caution
Do not apply waxes or polishes to
uncoated plastic, vinyl, rubber,
decals, simulated wood, or matte
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.

manufacturer’s instructions.
.Do not use cleaners that are not
intended for automotive use.
.Use a nonabrasive wax on the
vehicle after washing to protect and
extend the molding finish.
Carbon Fiber Care
Carbon fiber composite parts can be
washed and waxed like any other
parts. Use a clear or black pigmented
wax. See Composite Materials 0237.
Cleaning Exterior Lamps/Lenses,
Emblems, Decals, and Stripes
Use only lukewarm or cold water, a
soft cloth, and a car washing soap to
clean exterior lamps, lenses, emblems,
decals, and stripes. Follow instructions
under "Washing the Vehicle"
previously in this section.
Lamp covers are made of plastic, and
some have a UV protective coating. Do
not clean or wipe lamp covers when
dry. This can cause scratches to the
surface of the lamp cover.
Do not use any of the following items
on lamp covers:
.Abrasive or caustic agents.
.Washer fluids and other cleaning
agents in higher concentrations
than suggested by the manufacturer.
.Solvents, alcohols, fuels, or other
harsh cleaners.
.Ice scrapers or other hard items.
.Aftermarket appearance caps or
covers while the lamps are
illuminated, due to excessive heat
generated.
Caution
Failure to clean lamps properly can
cause damage to the lamp cover
that would not be covered by the
vehicle warranty.
Caution
Using wax on low gloss black finish
stripes can increase the gloss level
and create a non-uniform finish.
Clean low gloss stripes with soap
and water only.
Air Intakes
Clear debris from the air intakes
between the hood and windshield
when washing the vehicle.

402 VEHICLE CARE
Shutter System
The vehicle may have a shutter
system designed to help improve fuel
economy. Always keep the shutter
system clear of debris, snow and ice.
If the check engine light is activated,
please check to see if the shutter
system is clear of debris, snow or ice.
Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.
Clean rubber wiper blades using a
lint-free cloth or paper towel soaked
with windshield washer fluid or a mild
detergent. Wash the windshieldthoroughly when cleaning the blades.
Bugs, road grime, sap, and a buildup
of vehicle wash/wax treatments may
cause wiper streaking.
Replace the wiper blades if they are
worn or damaged. Damage can be
caused by extreme dusty conditions,
sand, salt, heat, sun, snow, and ice.
Weatherstrips
Apply weatherstrip lubricant on
weatherstrips to make them last
longer, seal better, and not stick or
squeak. Lubricate weatherstrips at
least once a year. Hot, dry climates
may require more frequent
application. Black marks from rubber
material on painted surfaces can be
removed by rubbing with a clean
cloth. See
Recommended Fluids and
Lubricants 0420.
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Caution
Using petroleum-based tire dressing
products on the vehicle may
damage the paint finish and/or
tires. When applying a tire dressing,
always wipe off any overspray from
all painted surfaces on the vehicle.
Wheels and Wheel Trim
Use a soft, clean cloth with mild soap
and water to clean the wheels. After
rinsing thoroughly with clean water,
dry with a soft, clean towel. A wax
may then be applied.
Caution
Chrome wheels and chrome wheel
trim may be damaged if the vehicle
is not washed after driving on roads
that have been sprayed with
magnesium chloride or calcium
chloride. These are used on roads
for conditions such as dust control.
Always wash the chrome with soap
and water after exposure.

VEHICLE CARE 403
Caution
To avoid surface damage on wheels
and wheel trim, do not use strong
soaps, chemicals, abrasive polishes,
cleaners, or brushes. Use only GM
approved cleaners. Do not drive the
vehicle through an automatic car
wash that uses silicon carbide tire/
wheel cleaning brushes. Damage
could occur and the repairs would
not be covered by the vehicle
warranty.
Brake System
Visually inspect brake lines and hoses
for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake
pads for wear and rotors for surface
condition. Inspect brake linings/shoes
for wear or cracks. Inspect all other
brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering, suspension,
and chassis components for damaged,
loose, or missing parts or signs of
wear at least once a year.Inspect power steering for proper
attachment, connections, binding,
leaks, cracks, chafing, etc.
Visually check constant velocity joint
boots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood
hinges, liftgate hinges, and the steel
fuel door hinges, unless the
components are plastic. Applying
silicone grease on weatherstrips with a
clean cloth will make them last
longer, seal better, and not stick or
squeak.
Underbody Maintenance
Every six months, use plain water to
flush any corrosive materials from the
underbody. Take care to thoroughly
clean any areas where mud and other
debris can collect.
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 fluid. Contaminated fluid will
decrease the life of the transfer case
and/or axles and should be replaced.
Sheet Metal Damage
If the vehicle is damaged and requires
sheet metal repair or replacement,
make sure the body repair shop
applies anti-corrosion material to
parts repaired or replaced to restore
corrosion protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoid
corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon and
attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface. See
“Finish Care”previously in
this section.

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.
Vinyl/Rubber
If equipped with vinyl floor and
rubber floor mats, use a soft cloth
and/or brush dampened with water to
remove dust and loose dirt. For more
thorough cleaning, use a mild soap
and water solution.
{Warning
Do not use cleaners that contain
silicone, wax-based products,
or cleaners that increase gloss on
vinyl/rubber floor and mats. These
cleaners can permanently change
the appearance and feel of the
vinyl/rubber and can make the floor
slippery. Your foot could slip while
operating the vehicle, and you
could lose control, resulting in a
crash. You or others could be
injured.
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.
2. Remove excess moisture by gently 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 into 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.
