7-2 Infotainment System
Theft-Deterrent Feature
THEFTLOCK®is designed to
discourage theft of the vehicle's
radio by learning a portion of the
Vehicle Identification Number (VIN).
The radio does not operate and
LOCKED displays if the radio is
stolen or moved to a different
vehicle.
When the ignition is in the off
position, a blinking red light on the
upper left side of the radio indicates
that THEFTLOCK
®is armed.

Air Delivery Mode Control: Turn
clockwise or counterclockwise to
change the direction of the airflow in
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.
0 (Defrost): This clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield and side window
outlets. The system runs the air
conditioning system unless the
outside temperature is near or
below freezing. Recirculation is
not available in this mode.
Do not drive the vehicle until all the
windows are clear. #
(Air Conditioning): Press to
turn the air conditioning system
on or off. An indicator light comes
on when the air conditioning is
turned on. This system cools and
dehumidifies the air entering the
vehicle.
The air conditioning will not
function if the fan is turned off.
If air conditioning is selected with
fan off, the indicator light flashes
three times and then turns off.
A slight change in engine
performance may occur when the
air conditioning compressor shuts
off and turns on again. This is
normal. The system is designed
to make adjustments to help with
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.

Use the air outlets located in the
center and on the side of the

the airflow from left to right.Operation Tips.Use the recirculation mode for
maximum air conditioning
performance.
.Clear away any ice, snow or
leaves from the air inlets at the
base of the windshield that may
block the flow of air into the
vehicle.
.Use of non-HUMMER approved
hood deflectors may adversely
affect the performance of the
system.
.Keep the path under the front

Steering in Emergencies
There are times when steering can
be more effective than braking. For
example, you come over a hill and
find a truck stopped in your lane,
or a car suddenly pulls out from
nowhere, or a child darts out from
between parked cars and stops right
in front of you. These problems can
be avoided by braking—if you can
stop in time. But sometimes you
cannot stop in time because there
is no room. That is the time for
evasive action —steering around
the problem.
The vehicle can perform very well
in emergencies like these. First
apply the brakes. See Braking
on
page 9‑3. It is better to remove
as much speed as possible from
a collision. Then steer around
the problem, to the left or right
depending on the space available.
An emergency like this requires
close attention and a quick decision.
If holding the steering wheel at the
recommended 9 and 3 o'clock
positions, it can be turned a full
180 degrees very quickly without
removing either hand. But you have
to act fast, steer quickly, and just as
quickly straighten the wheel once
you have avoided the object.
The fact that such emergency
situations are always possible is a
good reason to practice defensive
driving at all times and wear safety
belts properly.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving.
If the level of the shoulder is
only slightly below the pavement,
recovery should be fairly easy.
Ease off the accelerator and
then, if there is nothing in the
way, steer so that the vehicle
straddles the edge of the pavement.
