HUMMER H3 2009 Owners Manual

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 to
preserve 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
preserve and 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 reections in
the windshield and even make
it difficult to see through the
windshield under certain conditions.
Care of Safety Belts
Keep belts clean and dry.
{CAUTION
Do not bleach or dye safety belts.
It may severely weaken them.
In a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Service and Appearance Care 5-85

Weatherstrips
Silicone grease on weatherstrips will
make them last longer, seal better,
and not stick or squeak. Apply
silicone grease with a clean cloth.
During very cold, damp weather
frequent application may be
required. SeeRecommended Fluids
and Lubricants on page 6-12.
Washing Your Vehicle
The best way to preserve the
vehicle’s nish is to keep it clean by
washing it often.
Notice:Certain cleaners contain
chemicals that can damage the
emblems or nameplates on the
vehicle. Check the cleaning
product label. If it states that it
should not be used on plastic
parts, do not use it on the vehicle
or damage may occur and it would
not be covered by the warranty.
Do not wash the vehicle in direct
sunlight. Use a car washing soap.
Do not use cleaning agents that arepetroleum 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/retailer. 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 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 5-86.
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.
5-86 Service and Appearance Care

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.
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
Service and Appearance Care 5-87

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.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.
5-88 Service and Appearance Care

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.
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.
Service and Appearance Care 5-89

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.
Vehicle Identication
Vehicle Identication
Number (VIN)
This is the legal identier for your
vehicle. It appears on a plate in
the front corner of the instrument
panel, on the driver side. It can
be seen through the windshield from
outside the vehicle. The VIN also
appears on the Vehicle Certication
and Service Parts labels and the
certicates of title and registration.
Engine Identication
The eighth character in the VIN
is the engine code. This code helps
identify the vehicle’s engine,
specications, and replacement
parts. See “Engine Specications”
underCapacities and Specifications
on page 5-96for your vehicle’s
engine code.
Service Parts

Electrical System
Add-On Electrical
Equipment
Notice:Do not add anything
electrical to the vehicle unless you
check with your dealer/retailer
rst. Some electrical equipment
can damage the vehicle and the
damage would not be covered by
the vehicle’s warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle’s battery, even if the vehicle
is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing Your Airbag-Equipped
Vehicle on page 1-58.
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 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.
Power and Heated Seat
Circuit Breakers
There is a circuit breaker located
underneath the driver’s side
front seat that controls the power
and heated seat functions.
Fuses and Circuit
Breakers
The wiring circuits in your vehicle
are protected from short circuits by a
combination of fuses and circuit
breakers. 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.
If you ever have a problem on the
road and do not have a spare
fuse, you can borrow one that has
the same amperage. Just pick some
feature of your vehicle that you
can get along without — like the
radio or cigarette lighter — and use
its fuse, if it is the correct amperage.
Replace it as soon as you can.
