2007 HUMMER H2 Owners Manual

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 495.
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. SeeVehicle
Care/Appearance Materials on page 501.
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 your vehicle.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.
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 in a
garage or covered whenever possible.
497

Windshield, Backglass, and Wiper
Blades
If the windshield is not clear after using the
windshield washer, or if the wiper blade chatters
when running, wax, sap or other material may
be on the blade or windshield.
Clean the outside of the windshield with a
full-strength glass cleaning liquid. The windshield
is clean if beads do not form when you rinse it
with water.
Grime from the windshield will stick to the wiper
blades and affect their performance. Clean the
blade by wiping vigorously with a cloth soaked
in full-strength windshield washer solvent.
Then rinse the blade with water.
Check the wiper blades and clean them as
necessary; replace blades that look worn.
Aluminum Wheels
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use only
GM-approved cleaners on 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:Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
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 the surface could
be damaged. Do not use chrome polish on
aluminum wheels.
498

Notice:If you drive your vehicle through an
automatic car wash that has silicone carbide
tire cleaning brushes, you could damage
the aluminum or chrome-plated wheels.
The repairs would not be covered by your
warranty. Never drive a vehicle equipped with
aluminum or chrome-plated wheels through
an automatic car wash that uses silicone
carbide tire cleaning brushes.
Do not take the vehicle through an automatic car
wash that has silicone carbide tire cleaning
brushes. These brushes can also damage the
surface of these wheels.
Tires
To clean the tires, use a stiff brush with tire
cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the
paint nish and/or tires. When applying a tire
dressing, always wipe off any overspray
from all painted surfaces on your 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 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.
Larger areas of nish damage can be corrected in
your dealer’s body and paint shop.
499

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 or
an underbody car washing system can do this
for you.
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,
GM 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’s side. You can see
it if you look through the windshield from outside
your vehicle. The VIN also appears on the
Certication/Tire 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 will help you identify your vehicle’s
engine, specications, and replacement parts.
Service Parts Identication Label
You will nd this label on the inside of the glove
box. It is very helpful if you ever need to order
parts. On this label, you will nd the following:
VIN
Model designation
Paint information
Production options and special equipment
Do not remove this label from the vehicle.
502

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 88.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., the wiper will
stop until the motor cools. If the overload is
caused by some electrical problem and not snow,
etc., be sure to get 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.
503

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.
If you ever have a problem on the road and
don’t 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.
Instrument Panel Fuse Block
The fuse block access
door is located on the
driver’s side edge of
the instrument panel.
Pull off the cover to
access the fuse block.
To remove fuses if you don’t have a fuse extractor,
hold the end of the fuse between your thumb
and index nger and pull straight out.
You may have spare fuses located behind the
fuse block access door. These can be used
to replace a bad fuse. However, make sure it is
of the correct amperage.
