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 5-91.
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.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
Accessory Power Outlets
Your vehicle is equipped with accessory power outlets.
The outlets can be used to plug in electrical equipment
such as a cellular telephone, CB radio, etc.
If you have a vehicle with a center storage compartment
located on the instrument panel, you may have an
accessory power outlet in the storage drawer. There is
also an outlet on the front passenger’s seat near
the umbrella tray.There are two accessory power outlets in the rear seat
area located on the door armrests next to the ashtrays.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover it with
the protective cap.
The accessory power outlet will only operate when the
ignition is in ACCESSORY or ON and for 10 minutes
after turning the ignition OFF. If you would like the
accessory power outlet to operate regardless of ignition
position, and for extended periods of time, see your
dealer for more information.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain accessory power plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem see your dealer for additional information on the
accessory power outlets.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.

Manual Operation
yMODEz:Pressing the MODE switch and changing
the mode cancels automatic operation and places the
system in manual mode. Press AUTO to return to
automatic operation.
To change the current mode, select one of the following:
F(Vent):This mode directs air to the instrument
panel outlets.
*(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets.
Some air may be directed toward the windshield.
In automatic operation, cooler air is directed to the upper
outlets and warmer air to the oor outlets.
7(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets, for the side windows, and a little air directed to
the windshield.
The MODE switch can also be used to select the
oor/defog mode. Information on defogging and
defrosting can be found later in this section.
y9z(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 3-36
andScheduled Maintenance on page 6-4.
?(Recirculation):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 heat or cool the air inside your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. When the button is pressed, an indicator
light will come on. The air-conditioning compressor also
comes on.
Driver’s Temperature Knob:Press this knob to turn
the entire climate control system on or off. Turn this
knob clockwise or counterclockwise to manually
increase or decrease the temperature inside your
vehicle.
3-31

yPASS TEMPz(Passenger’s Temperature):
Press this switch to turn the passengers’ climate control
systems on. Press this switch to manually increase
or decrease the temperature for the front passenger.
PASS OFF (Passenger’s Climate Control):Press this
button to turn all passenger climate control systems off.
If the passenger’s temperature switch is turned off, the
driver’s temperature knob will control the temperature for
the entire vehicle.
A/C (Air Conditioning):Press this button to override
the automatic system and turn the air-conditioning
system on or off. When in AUTO the air-conditioning
compressor will come on automatically, as necessary.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.For quick cool down on hot days:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
6. Open all outlets.
Using these settings together 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.
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.
If your vehicle has the memory option, it can be used to
recall your climate control settings. For more information,
seeClimate Controls Personalization on page 3-39.
3-32

Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside your vehicle, then uses the
information to maintain the selected temperature 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 in the
middle of the instrument panel, near the windshield,
or the system will not work properly.There is also a sensor located behind the front grill.
This sensor reads the outside air temperature and helps
to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could cause a
false reading in the temperature.
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
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use the defrost mode (FRONT) to
remove fog or frost from the windshield more quickly.
yMODEz:Press this button until the oor/defog
symbol appears on the display.
.(Floor/Defog):This mode directs the air equally
between the windshield and the oor outlets. When you
select this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in
the oor/defog mode.
3-33

1FRONT (Defrost):Pressing FRONT directs most of
the air to the windshield and the side window outlets, with
some air directed to the oor outlets. In this mode, the
system will automatically turn off recirculation and run
the air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode. 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
ignition is in ON.
=REAR: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 approximately
10 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately
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 mirror when the
REAR button is pressed.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow. Use the thumbwheel
located next to the outlets to turn them on and off.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
3-34

*(Bi-Level):This mode directs half the air to the
upper outlets, and then directs the remaining air to the
oor outlets.
7(Floor):This mode directs the air to the oor
outlets.
y9z(Fan):Pressing this switch cancels automatic
operation and places the system in manual mode.
Press this switch to increase or decrease the fan speed.
Press the MODE switch until AUTO is displayed to
return to automatic operation.
yTEMPz(Temperature):Press this switch to
increase or decrease the temperature for the rear seat
passengers.
For cool air to be sent to the rear of the vehicle, the
air-conditioning system on the main climate-control
panel must be on. If it is not on, then the temperature in
the rear of the vehicle will remain at cabin temperature.
Be sure to keep the area under the front seats clear
of any objects so that the air inside of your vehicle can
circulate effectively.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/lter, it may need to
be changed periodically. For how often to change the
passenger compartment air lter, seeScheduled
Maintenance on page 6-4.
The access panel for the passenger compartment air
lter is located under the hood near the windshield,
on the passenger’s side of the vehicle.

Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions and
may damage the emission control system on your
vehicle. Diagnosis and service may be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see “If the
Light Is On Steady” following. If the light is still ashing,
follow the previous steps, and see your dealer for
service as soon as possible.

CHECK GAS CAP – 61:This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it is on properly.
CHECK OIL LEVEL – 36:For correct operation of the
low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message may
appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground
with the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been
off for a few minutes and your vehicle is on a level
surface. Then check the dipstick and add oil if
necessary. SeeEngine Oil on page 5-14.
CHECK TIRE PRESSURE – 144:This message is
displayed when the Tire Pressure Monitor (TPM) system
detects a low or high tire pressure condition in one or
more of the road tires.By pressing the INFO button up or down, the DIC
display will show which tire or tires do not have the
correct ination pressure. The system will display the air
pressure, the tire location (LF, RF, RR or LR), and
LOW TIRE if the air pressure is low or HIGH TIRE if the
air pressure is high. The tire pressure information is
available in English or metric measurements. For
example, a driver’s side front tire that is low may be
shown as: 22 PSI LF TIRE LOW.
The correct tire ination pressure should be set to those
shown on the Tire and Loading Information label. See
Loading Your Vehicle on page 4-30for the location
of this label. For more information regarding proper tire
ination, seeInation - Tire Pressure on page 5-65.
If a tire is low, you should stop as soon as possible
and inspect your tire(s) for damage. If a tire is at,
seeIf a Tire Goes Flat on page 5-76.
Once the TPM system detects the low or high tire
pressure condition, the message CHECK TIRE
PRESSURE will be displayed whenever you start the
engine. To remove or clear the CHECK TIRE
PRESSURE message, you will need to set the tire(s) to
the proper tire pressure. SeeInation - Tire Pressure
on page 5-65. SeeTire Pressure Monitor Operation on
page 5-68for more information.
