2009 HUMMER H3 tire pressure

Vehicles equipped with a tire
pressure monitoring system may
give an inaccurate low-pressure
warning if non-TPC spec rated
tires are installed on your
vehicle. Non-TPC Spec rated
tires may give a low-pressure
warning that is higher or lower
than the proper warning level
you would get with TPC
Spec rated tires. SeeTire
Pressure Monitor System on
page 5-52.
Your vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label.
SeeLoading the Vehicle
on page 4-35, for more
information about the Tire and
Loading Information Label
and its location on your vehicle.Different Size Tires and
Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires,
this could affect the way your vehicle
performs, including its braking,
ride and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as anti-lock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{CAUTION
If you add different sized
wheels, your vehicle may not
provide an acceptable level of
performance and safety if tires not
recommended for those wheels
are selected. You may increase
the chance that you will crash and
suffer serious injury. Only use GM
specic wheel and tire systems
developed for your vehicle, and
have them properly installed by a
GM certied technician.
SeeBuying New Tires on page 5-59
andAccessories and Modifications
on page 5-3for additional
information.

Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can
sometimes be repaired). See your
dealer/retailer if any of these
conditions exist.
Your dealer/retailer will know the
kind of wheel you need.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one
it replaces.If you need to replace any of your
wheels, wheel bolts, wheel nuts,
or Tire Pressure Monitor System
(TPMS) sensors, replace them only
with new GM original equipment
parts. This way, you will be sure
to have the right wheel, wheel bolts,
wheel nuts, and TPMS sensors
for your vehicle.
{CAUTION
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
on your vehicle can be dangerous.
It could affect the braking and
handling of your vehicle, make
your tires lose air and make you
lose control. You could have a
collision in which you or others
could be injured. Always use the
correct wheel, wheel bolts, and
wheel nuts for replacement.Notice:The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
SeeChanging a Flat Tire on
page 5-66for more information.
Used Replacement Wheels
{CAUTION
Putting a used wheel on the
vehicle is dangerous. You cannot
know how it has been used or how
far it has been driven. It could fail
suddenly and cause a crash. If you
have to replace a wheel, use a
new GM original equipment wheel.

To store the jack tool bag and jack:
1. Return the tools to the jack
tool bag.
2. Secure the tool bag to the jack
by securely wrapping the straps
around the jack. Then, slide
the straps through the rings on
the bag and secure.
3. Reinstall the wing nut retainer to
fasten the jack and tool bag
under the rear seat.
Make sure that the wing nut
passes through the tool bag and
the jack before tightening it.
4. Turn the wing nut retainer
clockwise to secure.Spare Tire
The vehicle, when new, had a
fully-inated spare tire. A spare tire
may lose air over time, so check
its ination pressure regularly.
SeeInflation - Tire Pressure on
page 5-51andLoading the Vehicle
on page 4-35for information
regarding proper tire ination and
loading your vehicle. For instruction
on how to remove, install or store
a spare tire, seeRemoving the Flat
Tire and Installing the Spare Tire
on page 5-72andStoring a Flat or
Spare Tire and Tools (H3) on
page 5-78orStoring a Flat or Spare
Tire and Tools (H3T) on page 5-80.
After installing the spare tire on
your vehicle, you should stop
as soon as possible and make sure
the spare is correctly inated.The spare tire does not have a Tire
Pressure Monitor System sensor.
You may get a low pressure warning
light. SeeTire Pressure Monitor
Operation on page 5-54. Have the
damaged or at road tire repaired or
replaced as soon as you can.
Do not mix tires and wheels of
different sizes, because they will not
t. Keep your spare tire and its
wheel together.

Owner Checks and
Services
These owner checks and services
should be performed at the
intervals specied to help ensure
vehicle safety, dependability,
and emission control performance.
Your dealer/retailer can assist
with these checks and services.
Be sure any necessary repairs are
completed at once. Whenever
any uids or lubricants are added
to the vehicle, make sure they
are the proper ones, as shown
inRecommended Fluids and
Lubricants on page 6-12.
At Each Fuel Fill
It is important to perform these
underhood checks at each fuel fill.
Engine Oil Level Check
Notice:It is important to check
the engine oil regularly and
keep it at the proper level.
Failure to keep the engine oil
at the proper level can cause
damage to the engine not covered
by the vehicle warranty.
Check the engine oil level and
add the proper oil if necessary.
SeeEngine Oil on page 5-13.
Engine Coolant Level Check
Check the engine coolant level
and add DEX-COOL®coolant
mixture if necessary. SeeEngine
Coolant on page 5-23.
Windshield Washer Fluid
Level Check
Check the windshield washer uid
level in the windshield washer
uid reservoir and add the proper
uid if necessary.
At Least Once a Month
Tire Ination Check
Inspect the vehicle’s tires and make
sure they are inated to the correct
pressures. Do not forget to check
the spare tire. SeeInflation - Tire
Pressure on page 5-51. Check to
make sure the spare tire is stored
securely. SeeChanging a Flat Tire
on page 5-66.
Tire Wear Inspection
Tire rotation may be required for
high mileage highway drivers prior to
the Engine Oil Life System service
notication. Check the tires for
wear and, if necessary, rotate the
tires. SeeTire Inspection and
Rotation on page 5-57.
Maintenance Schedule 6-9

This data can help provide a better
understanding of the circumstances
in which crashes and injuries occur.
Important:EDR data is recorded
by your vehicle only if a non-trivial
crash situation occurs; no data
is recorded by the EDR under
normal driving conditions and no
personal data (e.g., name, gender,
age, and crash location) is
recorded. However, other parties,
such as law enforcement, could
combine the EDR data with the type
of personally identifying data
routinely acquired during a crash
investigation.
To read data recorded by an EDR,
special equipment is required,
and access to the vehicle or the
EDR is needed. In addition to
the vehicle manufacturer, other
parties, such as law enforcement,
that have the special equipment, can
read the information if they have
access to the vehicle or the EDR.GM will not access this data or
share it with others except: with the
consent of the vehicle owner or,
if the vehicle is leased, with
the consent of the lessee; in
response to an official request of
police or similar government office;
as part of GM’s defense of
litigation through the discovery
process; or, as required by law. Data
that GM collects or receives may
also be used for GM research needs
or may be made available to
others for research purposes, where
a need is shown and the data is
not tied to a specic vehicle
or vehicle owner.
OnStar®
If your vehicle has OnStar and you
subscribe to the OnStar services,
please refer to the OnStar Terms and
Conditions for information on data
collection and use. See alsoOnStar
®
System on page 2-39in this manual
for more information.
Navigation System
If your vehicle has a navigation
system, use of the system may
result in the storage of destinations,
addresses, telephone numbers, and
other trip information. Refer to the
navigation system operating manual
for information on stored data and for
deletion instructions.
Radio Frequency
Identication (RFID)
RFID technology is used in some
vehicles for functions such as
tire pressure monitoring and ignition
system security, as well as in
connection with conveniences such
as key fobs for remote door
locking/unlocking and starting, and
in-vehicle transmitters for garage
door openers. RFID technology in
GM vehicles does not use or record
personal information or link with
any other GM system containing
personal information.
