You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Operation
and Displays on page 3-60for 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.
Manual Operation
wPWRx(Power/Temperature):Press the PWR
button on the left side of the climate control panel to turn
the entire climate control system on or off. Press the
up or down arrow on the switch to manually increase or
decrease the temperature inside the vehicle.
Press the PWR button on the right side of the climate
control panel to turn the passenger’s climate control
system on or off. Press the up or down arrow on
the switch to manually increase or decrease the
temperature for the passenger.
If the passenger’s PWR button is off, the driver’s
temperature switch controls the temperature for the
entire vehicle.
«9ª(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-42
andScheduled Maintenance on page 7-4.
ªN«(Mode):Pressing the switch and changing the
mode cancels automatic operation and places the
system in manual mode. Press the AUTO button to
return to automatic operation.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
%(Bi-Level):This mode directs about half of the air to
the instrument panel outlets, and then directs most of the
remaining air to the oor outlets. In automatic operation,
cooler air is directed to the upper outlets and warmer air
to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the side window
outlets, and some of the air directed to the windshield.
The mode switch can also be used to select the
defog mode. Information on defogging and defrosting
can be found later in this section.

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.
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.
3-40

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.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
=(Rear Window Defogger):Press this button to
turn the rear window defogger on or off. Be sure to
clear as much snow from the rear window as possible.
The rear window defogger will turn off about 10 minutes
after the button is pressed when traveling less than
30 mph (48 km/h). If turned on again, the defogger
will only run for about ve minutes before turning off.
The defogger can also be turned off by pressing
the button again or by turning off the engine.
The heated outside rearview mirrors will heat to
help clear fog or frost from the surface of the
mirrors when the rear window defogger is on.

Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will ash for
several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
belt is already buckled, neither the chime nor the
light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol. The
system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag
sensor, the pretensioners, the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-36.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
The light should go out
and the system is ready.
If the airbag readiness light stays on after you start
the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.

REDUCED ENGINE POWER
This message displays when the vehicle is reducing
engine power because the transmission is being placed
in gear under conditions that may cause damage to
the vehicle’s engine, transmission, or ability to
accelerate. Reduced engine power can affect the
vehicle’s ability to accelerate. If this message is on,
but there is no reduction in performance, proceed
to your destination. The performance may be reduced
the next time the vehicle is driven. The vehicle may
be driven at a reduced speed while this message is on,
but acceleration and speed may be reduced. Anytime
this message stays on, the vehicle should be taken
to your dealer/retailer for service as soon as possible.
RIGHT DOOR AJAR
This message displays anytime the engine is running,
the transmission is not in PARK (P), and the passenger
door is open or ajar. A chime sounds if the vehicle’s
speed is greater than 3 mph (5 km/h).
SERVICE A/C
This message displays when the electronic sensors that
control the air conditioning and heating systems are
no longer working. Have the climate control system
serviced by your dealer/retailer if you notice a drop in
heating and air conditioning efficiency.
SERVICE ABS (Antilock Brake System)
If this message displays when you are driving, stop
as soon as possible and turn the ignition off. Then start
the engine again to reset the system. If the message
stays on, or comes back on again while you are driving,
your vehicle is in need of service. See your
dealer/retailer.
If the SERVICE ABS message is being displayed, the
Traction Control System (TCS) and StabiliTrak
®System
will also be disabled. The Driver Information Center
will scroll three messages: SERVICE ABS, SERVICE
TRACTION SYS, and SERVICE STABILITRAK, and the
antilock brake system and traction control warning
lights on the instrument panel cluster will be illuminated.
SeeAntilock Brake System Warning Light on page 3-51
andTraction Control System (TCS) Warning Light on
page 3-52. The driver can acknowledge these messages
by pressing the RESET button three times. When the

Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modifications
on page 6-3for more information.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 3-63for 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.

will not have to be replaced. If you drive on a deated
run-at tire for 25 miles (40 km) or less and at speeds of
55 mph (90 km/h) or less, there is a good chance that
the tire can be repaired. The tire can operate effectively
with no air pressure for up to 100 miles (160 km) at
speeds up to 55 mph (90 km/h), but the tire would then
have to be replaced. When a tire is lled with air, it
provides a cushion between the road and the wheel.
Because you will not have this cushion when driving on
a deated tire, try to avoid potholes that could damage
your wheel and require replacement of it.
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 seeRoadside Service on page 8-7.
{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 6-61. These
sensors contain batteries which are designed to last
for 10 years under normal driving conditions. See your
dealer/retailer if you ever need to have a wheel
replaced, or if the sensors ever need replacement.

How to Check
Use a good quality pocket-type gage to check
tire pressure. You cannot tell if your tires are
properly inated simply by looking at them. Radial
tires may look properly inated even when they
are under-inated. Check the tire’s ination
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
ination pressure is low, add air until you reach the
recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure readings
to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inated to the ination
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire ination pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire ination
pressure label, you should determine the proper
tire ination pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is signicantly under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inate them to the proper
pressure. Driving on a signicantly under-inated tire
causes the tire to overheat and can lead to tire failure.
Under-ination also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling
and stopping ability.
6-61

Tire Pressure Monitor Operation
The Tire Pressure Monitor System (TPMS) is designed
to warn the driver when a low tire pressure condition
exists. TPMS sensors are mounted onto each tire
and wheel assembly on your vehicle. The TPMS
sensors monitor the air pressure in the vehicle’s tires
and transmits the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the
low tire pressure warning
light, located in the
instrument panel cluster.
At the same time a message to check the pressure in a
specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light
and the DIC warning message appear at each ignition
cycle until the tires are inated to the correct ination
pressure. Using the DIC, tire pressure levels canbe viewed by the driver. For additional information and
details about the DIC operation and displays see
DIC Operation and Displays on page 3-60andDIC
Warnings and Messages on page 3-63.
The low tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct ination pressure for
your vehicle’s tires when they are cold. SeeLoading
Your Vehicle on page 5-22, for an example of the
Tire and Loading Information label and its location on
your vehicle. Also seeInflation - Tire Pressure on
page 6-60for additional information.
Your vehicle’s TPMS can warn you about a low tire
pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation on
page 6-65,When It Is Time for New Tires on page 6-66,
andTires on page 6-52.
Notice:Liquid tire sealants could damage the
Tire Pressure Monitor System (TPMS) sensors.
Sensor damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.
