Fog Lamps
Use fog lamps for better vision in foggy or misty
conditions.
The fog lamps control is located on the
multifunction lever next to the exterior lamp
control.
-(Fog Lamps):Turning the band to this
position will turn the fog lamps on.
When you turn the fog lamps on, the fog lamp
light will appear on the instrument panel cluster to
indicate that the fog lamps and the parking
lamps are on.
If you turn the high-beam headlamps on, the fog
lamps will turn off. They will turn on again
when you switch to low-beam headlamps.
The ignition must be on for the fog lamps to
operate. The fog lamps will turn off when the
ignition is turned off.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off
for you. A light sensor on top of the instrument
panel makes the Twilight Sentinel
®work, so
be sure it is not covered.
With Twilight Sentinel
®you will see the following
happen:
When it is dark enough outside, the front turn
signal lamps (DRL) will go off, and the
headlamps and parking lamps will come on.
The other lamps that come on with headlamps
will also come on.
When it is bright enough outside, the
headlamps will go off, and the front turn signal
lamps (DRL) will come on, as long as the
exterior lamp switch is in the AUTO position.
If you start your vehicle in a dark garage,
the automatic headlamp system will come on
immediately. Once you leave the garage, it will
take about one minute for the automatic headlamp
system to change to DRL if it is light outside.

How the System Works
URPA comes on automatically when the shift lever
is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). When
the system comes on, the three lights on the
display will illuminate to let you know that
the system is working. URPA senses how close
your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located
on the rear bumper. When you shift into
REVERSE (R) and an object is detected, the
following will occur in sequence depending on the
distance from the object:
At 5 feet (1.5 m) a chime will sound and
one amber light will be lit;
at 40 inches (1.0 m) both amber lights will be lit;
at 20 inches (0.5 m) a continuous chime will
sound and all three lights (amber/amber/red)
will be lit; and
at 1 foot (0.3 m) a continuous chime will sound
and all three lights (amber/amber/red) will ash.
URPA can detect objects 3 inches (7.6 cm) and
wider, and at least 10 inches (25.4 cm) tall, but it
cannot detect objects that are above trunklevel. In order for the rear sensors to recognize an
object, it must be within operating range.
If the URPA system is not functioning properly, the
display will ash red, indicating that there is a
problem. The light will also ash red while driving if
a trailer is attached to your vehicle, or a bicycle or
object is on the back of, or hanging out of your
trunk. The light will continue to ash until the trailer
or the object is removed and your vehicle is driven
forward at least 15 mph (25 km/h).
It may also ash red if the ultrasonic sensors are
not kept clean. So be sure to keep your rear
bumper free of mud, dirt, snow, ice and slush or
materials such as paint or the system may
not work properly. If after cleaning the rear bumper
and driving forward at least 15 mph (25 km/h),
the display continues to ash red, see your dealer.
For cleaning instructions, seeWashing Your
Vehicle on page 446.
It may also ash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph
(5 km/h). Other conditions that may affect system
performance include things like the vibrations
from a jackhammer or the compression of
air brakes on a very large truck.

Automatic Operation
AUTO (Automatic):When this button is pressed
and the temperature is set, the system will
automatically control the inside temperature, the
air delivery mode, the air conditioning compressor
and the fan speed. AUTO will appear on the
display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable
setting between 70°F (21°C) and 80°F (27°C).
An initial setting of 73°F (23°C) is suggested.
Choosing the warmest or coldest temperature
setting will not cause the system to heat or cool
any faster. If you set the system at the warmest
or coldest temperature setting, the system will
remain in manual mode at that temperature and
it will not go into automatic mode.
In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air
into your vehicle until warmer air is available.
The system will start out blowing air at the oor
but may change modes automatically asthe vehicle warms up to maintain the chosen
temperature setting. The length of time
needed for warm up will depend on the outside
temperature and the length of time that has
elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take
from 10 to 30 minutes. Then adjust the
temperature, if necessary.
You can switch from English to metric units
through the Driver Information Center (DIC). See
DIC Controls and Displays on page 204for
more information.
The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
Do not cover the solar sensor located in the
center of the instrument panel, near the
windshield. For more information on the solar
sensor, see “Sensors” later in this section.
179

A/C OFF (Air Conditioning):Press this button to
turn off the air conditioning compressor. Press
AUTO to return to automatic operation. The
compressor cannot be turned off in either the
defrost or oor/defog mode.
((Heated/Cooled Seat):Press this button to
turn the feature on. The button on the left controls
the driver’s seat and the button on the right
controls the passenger’s seat. Each press of the
button will take you to a different setting. The
settings available in order are HI HEAT, LO HEAT,
OFF, HI COOL, LO COOL and OFF. You will be
able to feel the temperature change in a few
minutes.
The feature will automatically turn off when the
vehicle is turned off.
?(Recirculation):Press this button to turn the
recirculation mode on or off. The air conditioning
compressor also comes on. This mode keeps
outside air from coming in the vehicle. It can be
used to prevent outside air and odors from
entering your vehicle or to help cool the air inside
your vehicle more quickly.Recirculation is not available in defrost or
oor/defog modes.
Using recirculation for long periods of time may
cause the air inside your vehicle to become
too dry. To prevent this from happening, after the
air in your vehicle has cooled, turn the
recirculation mode off.
Sensors
There are sensors to measure the temperature
and sun’s effect on passenger comfort.
The solar sensor on your vehicle monitors the
solar radiation then uses the information to
maintain the selected temperature when operating
in AUTO mode by initiating needed adjustments
to the temperature, the fan speed and the air
delivery system. The system may also supply
cooler air to the side of the vehicle facing the sun.
The recirculation mode will also be activated,
as necessary. Do not cover the solar sensor
located on the top of the instrument panel near
the windshield or the system will not work properly.
181

There is also a sensor located behind the front
bumper. This sensor reads the outside air
temperature and helps maintain the temperature
inside the vehicle. The outside temperature will be
displayed in the navigation system only when
the engine is running. Any cover on the front of the
vehicle could give a false reading of the
temperature.
If the outside temperature goes up, the display
temperature will not change until:
The vehicle’s speed is above 15 mph
(24 km/h) for ve minutes.
The vehicle’s speed is above 32 mph
(51 km/h) for two and one-half minutes.
These delays prevent false readings. If the
temperature goes down, the outside temperature
will be shown when you start the vehicle. If it
has been turned off for less than three hours, the
temperature will be recalled from the previous
vehicle operation.
There is also an inside temperature sensor
located to the left of the ignition button. The
automatic climate control system uses this sensor
to receive information, so if you block or cover
it, the system will not function properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to
clear fog or frost from your windshield. Use the
oor/defog mode to clear the windows of fog or
moisture and warm the passengers. Use defrost to
remove fog or frost from the windshield more
quickly.
-(Floor/Defog):Press the mode button until the
defog mode appears on the display. This mode
directs the air between the windshield, oor outlets
and side windows. When you select this mode,
the system turns off recirculation and runs the air
conditioning compressor unless the outside
temperature is near or below freezing.
1(Defrost):Press this button to direct most of
the air to the windshield, with some air directed
to the side windows. In this mode, the system will
automatically turn off the recirculation and run
the air conditioning compressor, unless the outside
temperature is near or below freezing. Do not
drive the vehicle until all the windows are clear.

Magnetic Ride Control
Magnetic Ride Control automatically adjusts the
ride of your vehicle. Automatic ride control is
achieved through a computer used to control and
monitor the suspension system. The controller
receives input from various sensors to determine
the proper system response. If the controller
detects a problem within the system, the DIC will
display a SERVICE RIDE CONTROL message.
SeeDIC Warnings and Messages on page 206for
more information. See your dealer for service.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It
works like a standard axle most of the time, but
when one of the rear wheels has no traction
and the other does, this feature will allow
the wheel with traction to move the vehicle.
StabiliTrak®System
The StabiliTrak®System is a computer controlled
system that helps the driver maintain directional
control of the vehicle in difficult driving conditions.
This is accomplished by selectively applying
any one of the vehicle’s brakes.
When you rst start your vehicle and begin to
drive away (6 mph (10 km/h)), especially during
cold weather, the message STABILITRAK
WARMING may be displayed in the Driver
Information Center (DIC), the instrument panel
cluster light will be on, and a chime will sound.

Some road hazards can damage a tire beyond
repair. This damage could occur even before you
have driven on the tire in a deated condition.
When a tire has been damaged, or if you
have driven any distance on a run-at tire, check
with an authorized run-at tire service center
to determine whether the tire can be repaired or
should be replaced. To maintain your vehicle’s
run-at feature, all replacement tires must
be self-supporting tires. As soon as possible,
contact the nearest authorized GM or run-at
servicing facility for inspection and repair or
replacement. To locate the nearest GM or run-at
servicing facility, call Roadside Assistance. For
phone numbers and Roadside Service details see
Roadside Service on page 487.
{CAUTION:
Run-at tires are constructed differently
than other tires and could explode during
improper service. You or others could be
injured or killed if you attempt to repair,
replace, dismount, or mount a run-at tire.
Let only an authorized run-at service
center repair, replace, dismount, and
mount run-at tires.
The valve stems on your run-at tires have
sensors that are part of the Tire Pressure Monitor
System (TPMS). SeeTire Pressure Monitor
System on page 423. These sensors contain
batteries which are designed to last for 10 years
under normal driving conditions. See your dealer if
you ever need to have a wheel replaced, or if
the sensors ever need replacement.
Notice:Using liquid sealants can damage the
tire valves and tire pressure monitor sensors in
your vehicle’s run-at tires. This damage would
not be covered by warranty. Do not use liquid
sealants in your vehicle’s run-at tires.
