Automatic Operation
AUTO (Automatic):The system
automatically controls fan speed, air
delivery, and air conditioning in
order to heat or cool the vehicle to
the desired temperature. When the
indicator light is on, the system is in
full automatic operation. If the air
delivery mode or fan setting is
manually adjusted, the auto
indicator turns off and displays will
show the selected settings.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting between
21°C (70°F) and 27°C (80°F).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster.
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 floor, 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.
English can be changed to metric
units through the Driver Information
Center (DIC). See Driver
Information Center (DIC)
on
page 5‑27.
Q/R(Temperature Control):
The temperature can be adjusted
separately for the driver and the
passenger. Press to increase or
decrease the automatic temperature
settings.
PASS (Passenger Climate
Control): Press to set a different
temperature for the passenger. Then adjust the passenger
temperature buttons to a
comfortable setting.
Pressing the PASS button again
automatically sets the passenger's
temperature to the driver's setting.
Turning the passenger's
temperature display off does not
shut the passenger's climate control
system off.
Manual Operation
O(Power):
Press to turn the
climate control system on or off.
When the climate control system is
turned off the air inlet defaults to
outside air.
D C(Fan Control): Press the
buttons to increase or decrease the
fan speed. Pressing either button
cancels automatic fan control. Press
AUTO to return to automatic
operation. The blower may reduce

If the airflow seems low when the
fan speed is at the highest setting,
the passenger compartment air filter
might need to be replaced. For more
information, seePassenger
Compartment Air Filter
on
page 8‑6and Scheduled
Maintenance on page 11‑3.
H G(Air Delivery Mode Control):
Press the buttons to change the
direction of the airflow. The current
mode appears in the display screen.
Changing the mode cancels the
automatic air delivery. Press AUTO
to return to automatic operation.
The outboard air outlets always
receive some airflow in every mode,
except defrost.
To change the current mode, select
one of the following:
Y(Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets. In automatic operation, cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
[(Floor):
Air is directed to the
floor outlets, with some air directed
to the windshield and outboard
outlets.
-(Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor, and
side window outlets. When this
mode is selected, the system turns
off recirculation and runs the
air-conditioning compressor unless
the outside temperature is at or
below freezing. If recirculation is
selected while in defog mode, it is
cancelled after 10 minutes.
0(Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield, with some air directed to
the side windows. In this mode, the
system automatically turns off
recirculation and runs the air-conditioning compressor, unless
the outside temperature is at or
below freezing.
This mode can also cause the fan
speed and air temperature to
increase.
#(Air Conditioning):
Press to
turn the air conditioning system on
or off and override the automatic
system. When in AUTO, the air
conditioning compressor comes on
automatically, as needed.
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.
M(Recirculation): Press to turn
on recirculation. An indicator light
comes on. Air is recirculated inside
the vehicle. It helps to quickly cool
the air inside the vehicle or prevent
outside air and odors from entering.
Press the AUTO button to have the
system select the best air delivery
mode for the temperature setting.

Recirculation is not available in the
defrost mode and automatically
turns off 10 minutes after defog is
selected. This helps to limit window
fogging in the vehicle.
Using recirculation for long periods
of time could cause the air inside
the vehicle to become too dry or
stuffy. To prevent this from
happening, after the air in the
vehicle has cooled, select outside
air or press the auto button.
F(Outside Air):Press to turn
on the outside air. An indicator light
turns on. The outside air mode pulls
fresh air from outside the vehicle.
Outside air is always selected in
defrost mode to prevent fogging.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog or frost
from the rear window. It only works
when the ignition is in ON/RUN.
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger stays on
for about 15 minutes, before turning
off if the vehicle is moving at a
slower speed. At higher speeds, the
rear window defogger may stay on
continuously. With each additional
press, the defogger runs for about
10 minutes. The defogger can also
be turned off by turning off the
engine.
The heated outside rearview mirrors
turn on when the rear window
defogger button is on and helps to
clear fog or frost from the surface of
the mirrors. See Heated Mirrors
on
page 2‑27.
Notice: Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect your radio's ability to pick up stations
clearly. The repairs wouldn't be
covered by your warranty.
z/{(Heated and Ventilated
Seats): Press to heat or ventilate
the seat. See Heated and Ventilated
Front Seats on page 3‑12.
Remote Start Climate Control
Operation: For vehicles with
remote vehicle start, the climate
control system automatically heats
and cools the vehicle based on the
temperature inside and outside of
the vehicle. The climate control
displays will be blank. See Remote
Vehicle Start on page 2‑11.
In cold weather the windshield
defroster and/or rear window
defogger automatically turn on.
If the vehicle has heated seats, they
will also turn on.
When the ignition is turned to ON/
RUN, the climate control system
returns to the settings used before
the vehicle was last turned off. The
heated seats will turn off,
if equipped.

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 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.
The recirculation mode will also be
activated, as necessary.Do not cover the sensors or the
automatic climate control system will
not work properly.
Air Quality Sensor
For vehicles with an air quality
sensor, the climate control system
adjusts to limit some exhaust fumes
from being pulled inside your
vehicle.
Press the AUTO button on the
climate control to activate the air
quality sensor. The recirculation
indicator light comes on when poor
quality air is detected. The air
quality sensor will not maintain
recirculation for an extended period
to prevent the air inside the vehicle
from becoming too dry or stuffy.

8-6 Climate Controls
Under certain conditions, the air
quality sensor will not activate
recirculation, such as during cold
weather or with odors, like skunk. To
limit odors manually, press
Muntil
the condition has passed.
The air quality sensor system does
not protect against carbon monoxide
(CO), which you cannot see or
smell. See Engine Exhaust
on
page 9‑24.
Air Vents
Use the air outlets located in the
center and on the side of the
instrument panel to direct the
airflow. Use the thumbwheels near
the air outlets to open or close off
the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.Use of non‐GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter traps most of the dust and
pollen from the air entering the
vehicle. The filter will need to be
changed periodically. See
Scheduled Maintenance
on
page 11‑3.
Using the climate control system
without the passenger air filter
installed could let water or other
debris enter the system. This could
cause a water leak or noises. Make
sure a new air filter is installed after
removing the old one.

Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Service
on page 13‑7. To get help
and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
(Continued)
WARNING (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in the
Index.(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (Carbon
Monoxide) gas to get inside. CO
could overcome you and kill you.
You cannot see it or smell it, so
you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.
Run the engine for short periods
only as needed to keep warm, but
be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you

use spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production
tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one and
a half (1½) times as well on the
government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart significantly from the
norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.Traction
–AA, A, B, C
The traction grades, from
highest to lowest, are AA, A, B,
and C. Those grades represent
the tire's ability to stop on wet
pavement as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning, or peak traction
characteristics.
