the vehicle. The airflow can be set
between modes.
To change the current mode, select
one of the following:
H (Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is directed to the
instrument panel outlets, and the
remaining air to the floor outlets
and the defroster and side window
outlets. Cooler air is directed to the
upper outlets and warmer air to the
floor outlets. [
(Floor): Air is directed to the
floor outlets, side window outlets,
and defroster. Recirculation is not
available in this mode.
/ (Floor/Defog): This clears the
windows of fog and moisture. Air is
directed to the windshield, side
window, and floor outlets. The
system runs the air conditioning
unless the outside temperature is
near freezing or below. Recirculation
is not available in this mode.

fuel economy while still maintaining
the selected temperature.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.

9-54 Driving and Operating
When the vehicle is started and
begins to move, the system
performs several diagnostic checks
to insure there are no problems.
The system may be heard or felt
while it is working. This is normal
and does not mean there is a
problem with the vehicle.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. SeeCruise Control
on
page 9‑57.
If there is a problem detected with
StabiliTrak, a SERVICE STAB SYS
message displays on the Driver
Information Center (DIC). See
Driver Information Center (DIC)
on
page 5‑18for more information.
When this message is displayed,
the system is not working. Adjust
your driving accordingly. StabiliTrak comes on automatically
whenever the vehicle is started and
resets itself at each ignition cycle.
However, when the transfer case is
placed in Four‐Wheel‐Low Lock
mode, StabiliTrak is automatically
disabled. See

page 9‑46for more information.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle
is stuck in sand, mud, ice, or snow,
and it is necessary to “rock”the
vehicle to attempt to free it. See If
the Vehicle is Stuck
on page 9‑26.

Insuring Your Vehicle
Protect your investment in
your HUMMER vehicle with
comprehensive and collision
insurance coverage. There are
significant differences in the
quality of coverage afforded by
various insurance policy terms.
Many insurance policies provide
reduced protection to your
HUMMER vehicle by limiting
compensation for damage repairs
by using aftermarket collision parts.
Some insurance companies will not
specify aftermarket collision parts.
When purchasing insurance, we
recommend that you assure your
vehicle will be repaired with original
equipment collision parts. If such
insurance coverage is not available
from your current insurance carrier,
consider switching to another
insurance carrier.If your vehicle is leased, the leasing
company may require you to have
insurance that assures repairs
with Genuine Original Equipment
Manufacturer (OEM) parts or
Genuine Manufacturer replacement
parts. Read your lease carefully, as
you may be charged at the end of
your lease for poor quality repairs.
If a Crash Occurs
If there has been an injury, call
emergency services for help. Do not
leave the scene of a crash until all
matters have been taken care of.
Move the vehicle only if its position
puts you in danger, or you are
instructed to move it by a police
officer.
Give only the necessary information
to police and other parties involved
in the crash.

Roadside Service on page 13‑5.Gather the following information:
.Driver's name, address, phone
number
.Driver's license number
