Fan
9
(Fan):Turn the knob by this symbol, located on
the left side of the climate control panel, clockwise
or counterclockwise to increase or decrease the fan
speed. The fan speed will be temporarily reduced
between the transition to a new mode. The fan will
resume the original speed when the transition to the
new mode is complete.
9(Off):Turn the knob to this position to turn the
climate control system off. Only the heated seat
and/or rear defrost can be operated when the fan
is off.
Mode
Turn the middle knob to select the following modes:
H(Vent) (Outside Air):This mode directs
outside air to the instrument panel outlets. If driving
in city traffic, and the vehicle is stopped and
idling, or the weather is hot, press the recirculation
button. To prevent the air inside the vehicle
from becoming stale, be sure to turn off
recirculation periodically.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets, and the remaining
air to the oor outlets. Some air may be directed
toward the windshield. Slightly cooler air is directed
to the instrument panel outlets and warmer air is
directed to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed toward
the side window outlets and a little air directed to
the windshield.
In this mode, the system will automatically use
outside air. The air conditioning compressor will
be engaged unless the outside temperature
is 40°F (4°C) or below.
Recirculation cannot be selected when in this
mode even though the indicator light comes on
when the recirculation button is pressed.
The middle knob on the climate control panel can
also be used to select the defog or defrost mode.

Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the cool
window glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear frost or fog from the windshield.
Use the defog mode to clear the windows of
condensation and to warm the vehicle’s occupants.
Use the defrost mode to remove frost or
condensation from the windshield quickly.
See “Rear Window Defogger” later in this section
for information on clearing the rear window of
fog or ice.
.(Floor/Defog):Use the oor/defog mode to
clear the windows of fog or moisture and to
warm the passengers. This mode directs the air
equally between the windshield and the oor
outlets, along with some directed to the side
window outlets.
This mode will automatically use outside air. The
air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or
below. Recirculation cannot be selected when
in this mode even though the indicator light comes
on when the recirculation button is pressed.
1(Defrost):Use the defrost mode to remove
fog or frost from the windshield more quickly. This
mode directs most of the air to the windshield
and the side window outlets, with some air directed
to the oor outlets. This mode has a timer and
will shut off after ve minutes.
This mode will automatically use outside air. The
air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or
below. Recirculation cannot be selected when
in this mode even though the indicator light comes
on when the recirculation button is pressed.
Temperature
The knob on the right of the climate control panel
is the temperature adjustment that can be used
with any of the climate control modes.
Turn the knob clockwise for warmer settings and
counterclockwise for colder settings.
159

Air Conditioning
#
(Air Conditioner):Press this button to turn
the air conditioning compressor on or off. An
indicator light to the right of the button will come
on. This button has no control over the air
conditioning compressor when in Floor/Defog and
Defrost modes. The instrument panel brightness
control may have to be adjusted to the highest
setting in order to see the indicator. See
Instrument Panel Brightness on page 147for
additional information.
On hot days during the vehicle’s initial start-up,
open the windows to let hot inside air escape; then
close them. This helps to reduce the time it
takes for the vehicle to cool down. It also helps
the system to operate more efficiently.
For quicker cool down on hot days, do the
following:
1. Select any mode setting between vent and
the setting before defrost.
2. Select the air conditioner.
3. Select the coolest temperature.
4. Select the highest climate control fan speed.Using these settings will set recirculation for quicker
cool down (the light indicator will not turn on).
If outside air is desired, press the recirculation
button twice.
Using these settings together for long periods of
time may cause the air inside the vehicle to
become too dry. To prevent this from happening,
after ve minutes the recirculation door will
open slightly to allow some outside air into the
vehicle.
The air conditioning system removes moisture
from the air, so sometimes there may be a small
amount of water dripping underneath the
vehicle while it is idling or after the engine is
turned off. This is normal.
Recirculation
h
(Recirculation):Press this button to
activate the recirculation mode. With this selection,
inside air is recirculated into the vehicle. This
mode reduces outside air and odors from entering
the vehicle. It may also help to heat or cool the
air inside the vehicle more quickly.
160

Dual Automatic Climate Control
System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):Turn both the fan and mode
knob to AUTO for automatic control of the inside
temperature, the air delivery mode and the fan
speed. You may notice a delay of two to
three minutes before the fan comes on when the
automatic operation is used in cold weather.For the automatic system to function, the
temperature must be set between 60°F (15°C) and
90°F (32°C).
1. Adjust the temperature to a comfortable
setting.
2. Press the PASS button to turn the passenger
climate control system on and off. When the
passenger system is off, the driver’s
temperature setting is also used for the
passenger and the passenger display is off.
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 as the vehicle
warms up to maintain the chosen temperature
setting. The length of time needed for the air to
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.

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 the defrost mode to remove fog
or frost from the windshield more quickly.
-(Floor/Defog):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. Pressing the recirculation button,
while in this mode, will have no effect other than
turning on the indicator light.
1(Defrost):This mode directs 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. Pressing the
recirculation button, while in this mode, will have no
affect other than turning on the indicator light.
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 and off. Be
sure to clear as much snow from the rear window
as possible.
The rear window defogger will turn off about
20 minutes after the button is pressed. If turned
on again, the defogger will only run for about
20 minutes before turning off. The defogger can
also be turned off by pressing the button again or
by turning off the engine.
Do not drive the vehicle until all the windows are
clear.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.

Outlet Adjustment
Turn the air outlets, located in the middle and at
each outboard side of the instrument panel,
to adjust the direction of the airow.
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 the 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 the
vehicle more effectively.
If the airow seems low when the fan is at the
highest setting, the passenger compartment
air lter may need to be replaced. See
“Passenger Compartment Air Filter” following,
for more information.
Passenger Compartment Air Filter
The passenger compartment air lter is located
near the passenger’s side windshield wiper
arm, under the inlet grille.
The lter traps most of the pollen from entering
the climate control system. Similar to the engine’s
air lter, it may need to be changed periodically
to insure system performance. SeeScheduled
Maintenance on page 473for more information.
To change the passenger compartment air
lter, do the following:
1. Turn the ignition to ACC and the windshield
wipers on.
2. Turn the ignition to OFF when the windshield
wipers are in the upright position.
3. Raise the hood.
4. Disconnect the windshield washer pump hose
from the fender rail and the air inlet grille.
5. Remove the hood weather-strip from the
passenger’s side of the vehicle, peeling it
back halfway.

SeeBuying New Tires on page 416and
Accessories and Modications on page 336for
additional information.
Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary 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 conformto federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a comparative rating based
on the wear rate of the tire when tested under
controlled conditions on a specied government
test course. For example, a tire graded 150 would
wear one and a half (1.5) 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 signicantly 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 specied government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.

{CAUTION:
Idling the engine in a closed-in place or
with the climate control system off can
cause deadly carbon monoxide (CO). See
Engine Exhaust on page 119.
6. Start the vehicle. SeeStarting the Engine on
page 107for more information. The vehicle
must be running while using the air
compressor.
{CAUTION:
Inating something too much can make it
explode, and you or others could be
injured. Be sure to read the inator
instructions, and inate the tire to its
recommended pressure. Do not exceed
36 psi (248 kPa).7. Move the inator kit switch to the I (on)
position.
The inator kit will force sealant and air into
the tire. Sealant may leak from the puncture
hole until the vehicle is driven and the hole
has sealed.
8. Make sure there is a proper connection
between the tire valve stem and the
sealant lling hose by looking at the air
pressure gage. If there is not a pressure
reading while the compressor is running, the
connection between the inator kit and
the tire is bad.
Check the attachment between the sealant
lling hose and the tire valve stem.
