tow HUMMER H2 2005 Repair Manual

Make sure the spare tire is stored securely. Push, pull,
and then try to rotate or turn the tire. If it moves,
use the ratchet/wheel wrench to tighten the cable. See
Changing a Flat Tire on page 5-70.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeeScheduled Maintenance
on page 6-4.
When rotating your tires, always use the correct rotation
pattern shown here.
Do not include the spare tire in your tire rotation.After the tires have been rotated, adjust the front and
rear ination pressures as shown on the tire and loading
information label. SeeLoading Your Vehicle on
page 4-58andInation - Tire Pressure on page 5-60,
for more information. Make certain that all wheel
nuts are properly tightened. See “Wheel Nut Torque”
underCapacities and Specications on page 5-112.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off. SeeChanging a Flat
Tire on page 5-70.

If your vehicle is equipped with the air suspension
system, load leveling will not function with the inator
hose attached to the inator outlet.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions,
and inate any object only to its
recommended pressure.
If a Tire Goes Flat
It’s unusual for a tire to “blowout” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the at tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a at tire.
If a tire goes at, the next part shows how to use your
jacking equipment to change a at tire safely.

7. Remove all the wheel
nuts and take off the
at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to, to
get all the rust or dirt off.8. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.
5-83

9. After mounting the
spare, put the wheel
nuts back on with
the rounded end of
the nuts toward
the wheel.
10. Tighten each wheel nut by hand. Then use the
ratchet/wheel wrench to tighten the nuts, with
the UP mark facing you, clockwise until the wheel is
held against the hub.
You will not be tightening the nuts fully yet.

Washing Your Vehicle
The paint nish on the vehicle provides beauty, depth of
color, gloss retention, and durability.
The best way to preserve the vehicle’s nish is to keep it
clean by washing it often with lukewarm or cold water.
Do not wash the vehicle in the direct rays of the sun.
Use a car washing soap. Do not use strong soaps
or chemical detergents. Be sure to rinse the vehicle well,
removing all soap residue completely. GM-approved
cleaning products can be obtained from your dealer. See
Vehicle Care/Appearance Materials on page 5-100.
Do not use cleaning agents that are petroleum based,
or that contain acid or abrasives. All cleaning agents
should be ushed promptly and not allowed to dry on the
surface, or 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.
The overall height, width, and underbody clearances of
the HUMMER H2 are similar to current General
Motors’ full-size light duty trucks. This means a
HUMMER H2 should t in a standard car wash. But, if
your vehicle has added accessories like roof-mounted
lamps or a roof basket, it might not t properly in a
standard car wash.Notice:Certain add-on accessories can change the
dimensions of your vehicle. If you’ve added items
to the outside of your vehicle, it might not t
properly in a standard car wash. Your vehicle and
the car wash could be damaged. To help prevent
damage, know how accessories have changed the
dimensions of your vehicle and check with the
car wash manager before entering a car wash.
Notice:If you drive your vehicle through an
automatic car wash that does not have enough
clearance for any roof-mounted accessories (such
as off-road lamps or a roof basket) on your vehicle,
you can damage your vehicle. To avoid damaging
your vehicle in a car wash, remove any
roof-mounted accessories if you can, and do not
use an automatic car wash while roof-mounted
accessories are on your vehicle. SeePower Winch
Platform on page 4-57andOff-Road Lamps on
page 3-16for more information.
Also seeLuggage Carrier on page 2-55for
more information.

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
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.
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.
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.

(c)Visually inspect hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
ttings and clamps; replace with genuine GM parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(e)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
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 look for any opened or broken air bag
coverings, and have them repaired or replaced. (The air
bag system does not need regular maintenance.)
(f)Lubricate all key lock cylinders, hood latch assembly,
secondary latch, pivots, spring anchor, release pawl,
rear compartment hinges, outer liftgate handle pivot
points, rear door detent link, roller mechanism, liftgate
handle pivot points, latch bolt, fuel door hinge, cargo
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.SUT spare tire carrier hinge: Inspect for leaks and
lubricate if required. Remove the setscrew at the hinge
casting and add lubricant, moving the hinge back
and forth periodically, until lubricant can be seen coming
from the setscrew opening. Install setscrew and
tighten to 7 ft lb (9Y). SeeRecommended uids and
Lubricants on page 6-12for what lubricant to use.
(g)Check vent hose at transfer case for kinks and
proper installation.
(h)Change automatic transmission uid and lter 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, ush and rell cooling system. See Engine
Coolant on page 5-24for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ller neck.
Pressure test the cooling system and pressure cap.
(j)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the uid level checked. Add uid if needed.
