2009 HUMMER H3 spare tire

CAUTION (Continued)
So if you do not use proper care
before backing up, you could
hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in
vehicle damage, injury, or death.
Even though the vehicle has the
RVC system, always check
carefully before backing up by
checking behind and around
the vehicle.Rear Vision Camera Location
The image on the screen is provided
by the camera located on the rear
bumper.The image from the camera that
appears on the screen appears
farther than the actual distance.
The area displayed by the camera
is limited. The camera does not
display objects which are close to
either corner of the bumper or under
the bumper. On the H3, the spare
tire and carrier extends rearward
of the rear bumper. The area
displayed on the screen may vary
according to vehicle orientation
or road conditions. View of H3 Camera Location

The following illustration shows the
eld of view that the camera
provides.Notice:The spare tire extends
farther away from rear of the
vehicle than the trailer hitch
shown on rear vision camera
display. The spare tire could hit
an object even though there
appears to be enough distance
on the display between the trailer
hitch and objects behind you
causing vehicle or property
damage. Do not use this system
to judge the distance between
the spare tire and objects
behind you.

that uid levels are where they
should be, and that the spare tire
is fully inated.
Be sure to read all the
information about
four-wheel-drive vehicles in this
manual.
Make sure all underbody shields,
if the vehicle has them, are
properly attached.

off-roading where you will be
driving or check with law
enforcement people in the area.
Be sure to get the necessary
permission if you will be on
private land.
Loading Your Vehicle for
Off-Road Driving
{CAUTION
Cargo on the load oor piled
higher than the seatbacks
can be thrown forward during
a sudden stop. You or your
passengers could be injured.
Keep cargo below the top of
the seatbacks.
Unsecured cargo on the load
oor can be tossed about
when driving over rough
terrain. You or your
passengers can be struck by
ying objects. Secure the
cargo properly.
(Continued)
CAUTION (Continued)
Heavy loads on the roof raise
the vehicle’s center of gravity,
making it more likely to roll
over. You can be seriously or
fatally injured if the vehicle
rolls over. Put heavy loads
inside the cargo area, not on
the roof. Keep cargo in the
cargo area as far forward and
low as possible.
There are some important things to
remember about how to load
your vehicle.
The heaviest things should be on
the oor, forward of the rear axle.
Put heavier items as far forward
as you can.
Be sure the load is properly
secured, so things are not tossed
around.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo carried in it, and the people
who will be riding in the vehicle.If
there are a lot of options, equipment,
passengers or cargo in the vehicle,
it will reduce the tongue weight
the vehicle can carry, which will also
reduce the trailer weight the
vehicle can tow. If towing a trailer,
the tongue load must be added
to the GVW because the vehicle will
be carrying that weight, too. See
Loading the Vehicle on page 4-35
for more information about the
vehicle’s maximum load capacity.The trailer tongue weight (A) should
be 10 percent to 15 percent of
the total loaded trailer weight (B), up
to a maximum of 500 lbs (227 kg)
with a weight carrying hitch or
a weight distributing hitch.
Do not exceed the maximum
allowable tongue weight for the
vehicle. Choose the shortest hitch
extension that will position the
hitch ball closest to the vehicle.
This will help reduce the effect of
trailer tongue weight on the
rear axle.If the spare tire carrier is mounted
on the back of the vehicle and
the hitch extension is too short,
the spare tire may interfere
with trailer coupling or trailer tongue
jack operation on some types of
trailers.
After loading the trailer, weigh the
trailer and then the tongue,
separately, to see if the weights are
proper. If they aren’t, adjustments
might be made by moving some
items around in the trailer.

Front Axle
It is not necessary to regularly
check front axle uid unless a leak
is suspected or an unusual noise
is heard. A uid loss could indicate
a problem.
It is recommended that the front
axle uid be checked and lled by
your dealer/retailer.
Headlamp Aiming
The vehicle may have a visual
optical headlamp aiming system.
The aim has been preset at
the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim
may be affected and adjustment
may be necessary.
If oncoming vehicles ash their
high beams at you, this may also
mean the vertical aim needs to
be adjusted.
It is recommended that the vehicle
is taken to your dealer/retailer
for service if the headlamps need to
be re-aimed. It is possible however,
to re-aim the headlamps as
described.The vehicle should be:Placed so the headlamps are
25 ft. (7.6 m) from a light
colored wall or other at surface.
On a level surface which is level
all the way to a wall.
Placed so it is at a right angle to
the wall or other at surface.
Clear of any snow, ice, or
mudonit.
Fully assembled, the tires
properly inated, and all other
work stopped while headlamp
aiming is being performed.
Normally loaded with the spare
tire in its original location and a
full tank of fuel and one person or
160 lbs (75 kg) sitting on the
driver seat.

Ination - Tire Pressure
Tires need the correct amount of
air pressure to operate effectively.
Notice:Do not let anyone tell
you that under-ination or
over-ination is all right. It is
not. If your tires do not have
enough air (under-ination),
you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air
(over-ination), you can get
the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road
hazardsA vehicle specic Tire and
Loading Information label is
attached to your vehicle.
This label shows your vehicle’s
original equipment tires and
the correct ination pressures for
your tires when they are cold.
The recommended cold tire
ination pressure, shown on the
label, is the minimum amount
of air pressure needed to
support your vehicle’s maximum
load carrying capacity.
For additional information
regarding how much weight your
vehicle can carry, and an
example of the Tire and Loading
Information label, seeLoading
the Vehicle on page 4-35.
How you load your vehicle
affects vehicle handling and ride
comfort. Never load your vehicle
with more weight than it was
designed to carry.When to Check
Check your tires once a month
or more. Also check the tire
pressure of the spare tire. If your
vehicle has a compact spare
tire, it should be at 60 psi
(420 kPa). SeeSpare Tire on
page 5-82for additional
information.
How to Check
Use a good quality pocket-type
gage to check tire pressure.
You cannot tell if your tires are
properly inated simply by
looking at them. Radial tires may
look properly inated even
when they are underinated.
Check the tire’s ination
pressure when the tires are
cold. Cold means your vehicle
has been sitting for at least
three hours or driven no more
than 1 mile (1.6 km).
Service and Appearance Care 5-51

Remove the valve cap from
the tire valve stem. Press the tire
gage rmly onto the valve to
get a pressure measurement.
If the cold tire ination pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the ination pressure is low,
add air until you reach the
recommended amount.
If you overll the tire, release air
by pushing on the metal stem
in the center of the tire valve.
Recheck the tire pressure
with the tire gage.
Be sure to put the valve caps
back on the valve stems.
They help prevent leaks by
keeping out dirt and moisture.Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your vehicle’s
tires and transmit tire pressure
readings to a receiver located in
the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inated to
the ination pressure recommended
by the vehicle manufacturer on
the vehicle placard or tire ination
pressure label. (If your vehicle
has tires of a different size than
the size indicated on the vehicle
placard or tire ination pressure
label, you should determine the
proper tire ination pressure
for those tires.)As an added safety feature, your
vehicle has been equipped with
a tire pressure monitoring system
(TPMS) that illuminates a low
tire pressure telltale when one or
more of your tires is signicantly
under-inated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inate them
to the proper pressure. Driving on a
signicantly under-inated tire
causes the tire to overheat and can
lead to tire failure. Under-ination
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle’s handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if under-ination
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
