2009 GMC ACADIA Owner's Manual

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 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.
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 underWashing
Your Vehicle on page 5-84.
Finish Care
Occasional waxing or mild polishing
of the vehicle by hand may be
necessary to remove residue from
the paint nish. Approved cleaning
products can be obtained from
your dealer/retailer.
If the 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 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
damage the vehicle’s nish 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 nish looking
new, keep the vehicle garaged or
covered whenever possible.
Service and Appearance Care 5-85

Protecting Exterior Bright
Metal Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Washing with water is all
that is usually needed. However,
chrome polish may be used
on chrome or stainless steel trim,
if necessary.
Use special care with aluminum
trim. To avoid damaging protective
trim, never use auto or chrome
polish, steam or caustic soap
to clean aluminum. A coating of
wax, rubbed to high polish, is
recommended for all bright
metal parts.Windshield, Backglass,
and Wiper Blades
Clean the outside of the windshield
and backglass with glass cleaner.
Clean the rubber blades using a lint
free cloth or paper towel soaked with
windshield washer uid or a mild
detergent. Wash the windshield
thoroughly when you clean 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.
Wipers can be damaged by:
Extreme dusty conditions
Sand and salt
Heat and sun
Snow and ice, without proper
removal
Aluminum or
Chrome-Plated Wheels
and Trim
The vehicle may have either
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:Chrome wheels and
other chrome trim may be
damaged if the vehicle is not
washed after driving on roads
that have been sprayed with
magnesium, calcium or sodium
chloride. These chlorides are
used on roads for conditions
such as ice and dust. Always
wash the vehicle’s chrome with
soap and water after exposure.
5-86 Service and Appearance Care

Notice:Using strong soaps,
chemicals, abrasive polishes,
cleaners, brushes, or cleaners
that contain acid on aluminum
or chrome-plated wheels,
could damage the surface of
the wheel(s). The repairs would
not be covered by the warranty.
Use only approved cleaners
on aluminum or chrome-plated
wheels.
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 they could damage
the surface. Do not use chrome
polish on aluminum wheels.Notice:Using chrome polish on
aluminum wheels could damage
the wheels. The repairs would
not be covered by the warranty.
Use chrome polish on chrome
wheels only.
Use chrome polish only on
chrome-plated wheels, but avoid
any painted surface of the wheel,
and buff off immediately after
application.
Notice:Driving the vehicle
through an automatic car wash
that has silicone carbide tire
cleaning brushes, could damage
the aluminum or chrome-plated
wheels. The repairs would not be
covered by the warranty. Never
drive a vehicle equipped with
aluminum or chrome-plated
wheels through an automatic car
wash that uses silicone carbide
tire cleaning brushes.Tires
To clean the tires, use a stiff brush
with tire cleaner.
Notice:Using petroleum-based
tire dressing products on the
vehicle may damage the paint
nish and/or tires. When applying
a tire dressing, always wipe off
any overspray from all painted
surfaces on the vehicle.
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.
Service and Appearance Care 5-87

Finish Damage
Any stone chips, fractures or deep
scratches in the nish should be
repaired right away. Bare metal will
corrode quickly and may develop
into major repair expense.
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer/retailer.
Larger areas of nish damage
can be corrected in your dealer’s/
retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect
on the underbody. If these are not
removed, corrosion and rust can
develop on the underbody parts such
as fuel lines, frame, oor pan, and
exhaust system even though they
have corrosion protection.At least every spring, ush 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 ushed. Your dealer/retailer
or an underbody car washing
system can do this.
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 12,000 miles (20 000 km) of
purchase, whichever occurs rst.

Windshield Wiper Fuses
The windshield wiper motor is
protected by a circuit breaker and a
fuse. If the motor overheats due
to heavy snow or ice, the wiper will
stop until the motor cools. If the
overload is caused by some
electrical problem, have it xed.
Power Windows and
Other Power Options
Circuit breakers in the fuse block
protect the power windows and
other power accessories. When the
current load is too heavy, the
circuit breaker opens and closes,
protecting the circuit until the
problem is xed or goes away.
Fuses and Circuit
Breakers
The wiring circuits in your vehicle
are protected from short circuits
by a combination of fuses, circuit
breakers and fusible thermal
links. This greatly reduces the
chance of res caused by electrical
problems.
Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
you replace a bad fuse with a new
one of the identical size and rating.Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
you can.
Instrument Panel Fuse
Block
The instrument panel fuse block
is located under the instrument
panel on the passenger side of the
vehicle. Pull down on the cover
to access the fuse block.
