Tow HUMMER H3 2008 Workshop Manual

Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be used
on oor carpet and carpeted oor mats. For soils, always
try to remove them rst with plain water or club soda.
Before cleaning, gently remove as much of the soil as
possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper
towel. Allow the soil to absorb into the paper towel
until no more can be removed.
For solid dry soils: remove as much as possible and
then vacuum.
To clean, use the following instructions:
1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub
toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process
that was used with plain water.If any of the soil remains, a commercial fabric cleaner or
spot lifter may be necessary. When a commercial
upholstery cleaner or spot lifter is to be used, test a
small hidden area for colorfastness rst. If the locally
cleaned area gives any impression that a ring formation
may result, clean the entire surface.
After the cleaning process has been completed, a paper
towel can be used to blot excess moisture from the
fabric or carpet.
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 your leather and are
not recommended. Do not use silicone or wax-based
products, or those containing organic solvents to clean
your vehicle’s interior because they can alter the
appearance by increasing the gloss in a non-uniform
manner. Never use shoe polish on leather.

Washing Your Vehicle
The best way to preserve your 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 your
vehicle. Check the cleaning product label. If it states
that it should not be used on plastic parts, do not
use it on your 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
are petroleum based or that contain acid or abrasives,
as they can damage the paint, metal or plastic on
your vehicle. Approved cleaning products can be
obtained from your dealer/retailer. SeeVehicle
Care/Appearance Materials on page 5-99. 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 5-95.

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
Your 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 you do not wash your vehicle 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 your vehicle’s chrome
with soap and water after exposure.
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 approved cleaners on aluminum
or chrome-plated wheels.
The surface of these wheels is similar to the painted
surface of your vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because you could damage the surface. Do not
use chrome polish on aluminum wheels.

(d)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades, if
contaminated. Replace wiper blades that are worn or
damaged. See Windshield Wiper Blade Replacement on
page 5-52 and Windshield, Backglass, and Wiper
Blades on page 5-97 for more information.
(e)Make sure the safety belt reminder light and safety
belt assemblies are working properly. Look for any
other loose or damaged safety belt system parts. If you
see anything that might keep a safety belt system
from doing its job, have it repaired. Have any torn or
frayed safety belts replaced. Also see Checking
the Restraint Systems on page 1-69.
(f)Lubricate all key lock cylinders, hood latch assembly,
secondary latch, pivots, spring anchor, release pawl,
rear compartment hinges, outer swing-gate handle pivot
points, rear door detent link, roller mechanism,
swing-gate handle pivot points, latch bolt, fuel door
hinge, locks, and folding seat hardware. More frequent
lubrication may be required when exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.(g)Check vent hose at transfer case for kinks and
proper installation.
(h)Change automatic transmission fluid and filter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i)Drain, flush, and refill cooling system. This service
can be complex; you should have your dealer/retailer
perform this service. See Engine Coolant on page 5-27
for what to use. Inspect hoses. Clean radiator,
condenser, pressure cap, and filler neck. Pressure test
the cooling system and pressure cap.
(j)A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the fluid level checked. Add fluid if needed.
(k)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.

Insuring Your Vehicle
Protect your investment in your GM vehicle with
comprehensive and collision insurance coverage. There
are signicant differences in the quality of coverage
afforded by various insurance policy terms. Many
insurance policies provide reduced protection to your
GM vehicle by limiting compensation for damage repairs
by using aftermarket collision parts. Some insurance
companies will not specify aftermarket collision
parts. When purchasing insurance, we recommend that
you assure your vehicle will be repaired with GM
original equipment collision parts. If such insurance
coverage is not available from your current insurance
carrier, consider switching to another insurance carrier.
If your vehicle is leased, the leasing company may
require you to have insurance that assures repairs with
Genuine GM Original Equipment Manufacturer (OEM)
parts or Genuine Manufacturer replacement parts. Read
your lease carefully, as you may be charged at the
end of your lease for poor quality repairs.
If a Crash Occurs
Here is what to do if you are involved in a crash.
Try to relax and then check to make sure you are
all right. If you are uninjured, make sure that no
one else in your vehicle, or the other vehicle,
is injured.
If there has been an injury, call emergency services
for help. Do not leave the scene of a crash until all
matters have been taken care of. Move your
vehicle only if its position puts you in danger or you
are instructed to move it by a police officer.
Give only the necessary and requested information
to police and other parties involved in the crash.
Do not discuss your personal condition, mental
frame of mind, or anything unrelated to the crash.
This will help guard against post-crash legal action.
If you need roadside assistance, call GM Roadside
Assistance. SeeRoadside Assistance Program on
page 7-6for more information.
If your vehicle cannot be driven, know where the
towing service will be taking it. Get a card from
the tow truck operator or write down the driver’s
name, the service’s name, and the phone number.
7-12

Remove any valuables from your vehicle before it is
towed away. Make sure this includes your insurance
information and registration if you keep these
items in your vehicle.
Gather the important information you will need from
the other driver. Things like name, address, phone
number, driver’s license number, vehicle license
plate, vehicle make, model and model year, Vehicle
Identication Number (VIN), insurance company
and policy number, and a general description of the
damage to the other vehicle.
If possible, call your insurance company from the
scene of the crash. They will walk you through
the information they will need. If they ask for
a police report, phone or go to the police
department headquarters the next day and you can
get a copy of the report for a nominal fee. In
some states/provinces with “no fault” insurance
laws, a report may not be necessary. This is
especially true if there are no injuries and both
vehicles are driveable.
Choose a reputable collision repair facility for your
vehicle. Whether you select a dealer/retailer or a
private collision repair facility to x the damage,
make sure you are comfortable with them.
Remember, you will have to feel comfortable with
their work for a long time.
Once you have an estimate, read it carefully and
make sure you understand what work will be
performed on your vehicle. If you have a question,
ask for an explanation. Reputable shops welcome
this opportunity.
7-13

Managing the Vehicle Damage Repair
Process
In the event that your vehicle requires damage repairs,
GM recommends that you take an active role in its
repair. If you have a pre-determined repair facility of
choice, take your vehicle there, or have it towed there.
Specify to the facility that any required replacement
collision parts be original equipment parts, either new
Genuine GM parts or recycled original GM parts.
Remember, recycled parts will not be covered by your
GM vehicle warranty.
Insurance pays the bill for the repair, but you must live
with the repair. Depending on your policy limits, your
insurance company may initially value the repair using
aftermarket parts. Discuss this with your repair
professional, and insist on Genuine GM parts. Remember
if your vehicle is leased you may be obligated to have the
vehicle repaired with Genuine GM parts, even if your
insurance coverage does not pay the full cost.
If another party’s insurance company is paying for the
repairs, you are not obligated to accept a repair
valuation based on that insurance company’s collision
policy repair limits, as you have no contractual limits with
that company. In such cases, you can have control of
the repair and parts choices as long as cost stays within
reasonable limits.
Reporting Safety Defects
Reporting Safety Defects to the
United States Government
If you believe that your vehicle has a defect which
could cause a crash or could cause injury or
death, you should immediately inform the National
Highway Traffic Safety Administration (NHTSA)
in addition to notifying General Motors.
If NHTSA receives similar complaints, it may open
an investigation, and if it nds that a safety defect
exists in a group of vehicles, it may order a recall
and remedy campaign. However, NHTSA cannot
become involved in individual problems between
you, your dealer/retailer, or General Motors.
To contact NHTSA, you may call the Vehicle
Safety Hotline toll-free at 1-888-327-4236
(TTY: 1-800-424-9153); go to
http://www.safercar.gov; or write to:
Administrator, NHTSA
400 Seventh Street, SW.
Washington D.C., 20590
