2007 HUMMER H2 climate control

Ashtray(s) and Cigarette Lighter
If your vehicle has an ashtray, it is removable and
ts into the front cupholder. Pull up on the
ashtray door to open it.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle. Never
put ammable items in the ashtray.
To remove the ashtray, pull it out from the
console. To reinstall the ashtray, slide it back to
the original position.
To use the cigarette lighter, if equipped, push it in
all the way, and let go. When it’s ready, it will
pop back out by itself.
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in
while it is heating.

instrument panel outlets.
)(Bi-Level):This setting will deliver warmer air
to the oor and cooler air to the instrument
panel outlets.
6(Floor):This setting will deliver air to the
oor outlets.
-(Defog):See “Defogging and Defrosting” later
in this section.
@(Recirculation):Press this button to limit the
amount of outside air entering your vehicle. The
light on the recirculation button will glow. This is
helpful when you are trying to limit odors entering
your vehicle and for maximum air conditioning

revert to the auto recirculation function.
If you select recirculation while in defrost, defog or
oor, the light in the button will ash and then go out
to let you know that this is not allowed. This is
normal and helps to prevent fogging.
When the weather is cool or damp, operating the
system in recirculation for extended periods of time
may cause fogging of the vehicle’s windows. To
clear the fog, select either defog or front defrost.
You may also notice that the A/C compressor will
run while in recirculation mode. This is normal and
helps to prevent fogging.
9(Off):Press this button to turn off the entire
climate control system. Outside air will still enter the
vehicle, and will be directed to the oor. This
direction can be changed by pressing the mode

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform to
federal safety requirements and additional General
Motors Tire Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based
on the wear rate of the tire when tested under
controlled conditions on a specied government
test course. For example, a tire graded 150 would
wear one and a half (1.5) times as well on the
government course as a tire graded 100. The
relative performance of tires depends upon the
actual conditions of their use, however, and may
depart signicantly from the norm due to variations
in driving habits, service practices, and differences
in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA,
A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured under
controlled conditions on specied government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.
Warning:The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
