2007 HUMMER H2 Owners Manual

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your 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.
Tire Chains
Notice:Use tire chains only where legal and
only when you must. Use only SAE Class U-type
chains that are the proper size for your tires.
Install them on the rear axle tires and tighten
them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions. If you can
hear the chains contacting your vehicle, stop
and retighten them. If the contact continues,
slow down until it stops. Driving too fast or
spinning the wheels with chains on will
damage your vehicle.

Accessory Inator
Your vehicle may have an accessory inator
system. You can inate things like basketballs and
bicycle tires. You can also use it to bring your
tire pressure up to the proper pressure. The engine
must be running and the gearshift lever must be
in PARK (P) for the inator to operate.
The accessory inator
is located in the rear
compartment on
the passenger’s side
of the vehicle.The accessory inator
kit includes a hose and
three nozzle adapters.
To use the accessory inator, do the following:
1. Attach the appropriate nozzle adapter
to the end of the hose.
2. Attach that end of the hose to the object you
wish to inate.
3. Remove the dust cover and attach the hose
to the outlet.
466

The accessory inator hose also has a built-in
air pressure gage. As soon as you start to
inate an object it will automatically read the
current pressure.
4. Press and release the switch to turn the
accessory inator on. The indicator light
will remain on while the inator is running.When you are nished using the inator, press and
release the switch to turn it off. Place the inator kit
tools and the hose back in the pouch.
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 is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
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 would 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
the jacking equipment to change a at tire safely.
Changing a Flat Tire
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place.
Turn on your hazard warning ashers.
468

{CAUTION:
Changing a tire can be dangerous.
The vehicle can slip off the jack and roll
over or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Be sure the transfer case is in a
drive gear—not in NEUTRAL.
4. Turn off the engine and do not restart
while the vehicle is raised.
5. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not
move, you can put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire on
the other side, at the opposite end of the
vehicle.When you have a at tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
The following steps will tell you next how to use
the jack and change a tire.
