E. Air ConditioningF. Heated Seat
G. Fan Control
H. Defrost
I. Rear Window Defogger
J. Air Delivery Mode
ControlAUTO (Automatic):The system automatically
controls the fan speed, air delivery, air conditioning
and recirculation modes in order to heat or cool the
vehicle to the desired temperature.
To place the system in automatic mode:
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting,
generally, between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. If the system is set at the warmest
temperature setting, the system will try to
continuously heat the vehicle and will not adjust
the system down as the vehicle warms up.
To avoid blowing cold air in cold weather, the
system delays turning on the fan until warm air
is available. The system starts out blowing air
at the oor, but can automatically change modes
as the vehicle warms up to maintain the chosen
temperature setting. The length of time needed for
warm up depends on the outside temperature and
the length of time that has elapsed since the 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.
The display can be changed from English to metric units

Sensors
The solar sensor located on the instrument panel, near
the windshield, monitors the solar heat.
The interior temperature sensor located on the
instrument panel to the right of the steering wheel,
measures the temperature of the air inside the vehicle.
The climate control system uses the information
from these sensors to adjust the temperature, the fan
speed and the air delivery, in order to maintain the
selected temperature. The system may also supply
cooler air to the side of the vehicle facing the sun.
Do not cover the sensors or the automatic climate
control system will not work properly.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airow.
Turn the thumbwheel towards the vehicle door to open
the outlets and allow the maximum amount of air to
enter your vehicle. Turn the thumbwheel towards
the center console to close the outlets and minimize
the amount of air entering the vehicle.
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.
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,
seePassenger Compartment Air Filter on page 3-54.

Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air lter. There are two types of lters
available. There is a standard dust lter that traps small
particles including pollen. There is, also, a dust/odor lter
available that traps dust and pollen and uses a charcoal
element to help reduce many offensive odors from
entering your vehicle. The lter will need to be changed
periodically. For information on when to change the
passenger compartment air lter, seeScheduled
Maintenance on page 6-4.
Notice:Driving without a passenger compartment
air lter in place can cause water and small particles,
like paper and leaves, to be pulled into your climate
control system which may cause damage to it. Make
sure you always replace the old lter with a new one.The access panel for the passenger compartment air
lter is located under the hood near the windshield, on the
passenger side of the vehicle. SeeEngine Compartment
Overview on page 5-12for more information on location.
SeeDoing Your Own Service Work on page 5-4for
information on doing your own service work.
To access the passenger compartment air lter:
1. Pull back the rubber hood seal from the edge of the
leaf screen vent cover.
2. Remove the three fasteners that hold the lter
cover in place and slide the cover off.
3. To access the lter, remove the water deector by
lifting the outboard edge of the deector to release
the retention tab.

4. Lift the inboard edge of the deector to release the
retention tab.
5. Lift and slide the water deector toward the inboard
side and remove it.
6. The top edge of the lter should be visible. Reach
in and lift the lter out, pulling upward and toward
the front of the vehicle.
7. Insert the new air lter by sliding it back into place.
Make sure the arrow on the lter is pointing toward
the passenger compartment.
Reverse steps 1 through 3 to reinstall the water
deector, lter cover and the hood seal.Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there may
be a problem, check the section that explains what to do.
Follow this manual’s advice. Waiting to do repairs can be
costly and even dangerous.
