Comfort Controls
Heater and Air Conditioning Comfort
Controls
Fan Knob
The knob on the left side of the control panel adjusts the
fan speed. To increase airflow, turn the knob clockwise.
To decrease airflow, turn it counterclockwise. To turn
the fan off, turn the knob to OFF.Temperature Knob
The middle knob on the control panel lets you select the
temperature of the air flowing into the passenger area.
Turn the knob clockwise toward the red area for warmer
air. Turn the knob counterclockwise toward the blue area
for cooler air.
Mode Knob
The right knob on the control panel allows you to
choose the direction of air delivery.
(Vent): This mode directs the air through the
instrument panel outlets and the center floor console
outlets.
(Bi-Level): Air is delivered through the
instrument panel outlets and center floor console outlets,
as well as the floor outlets. The air flow can be divided
between panel and floor depending upon where the knob
is placed. Pressing the A/C button while in this mode
causes cooler air to come out of the instrument panel
outlets and center floor console outlets and warmer air
to come out of the floor outlets.

3-5 Heating
The heater works best if you keep your windows closed
while using it. On cold days, use the floor or bi
-level
modes with the temperature knob in the red area.
On cold days, approximately 32
F (
-0
C) or lower you
may experience differences in how the transmission
shifts until the engine is warm. This feature
automatically reduces the time it takes for the engine to
reach normal operating temperature and shortens the
time it takes the heater to reach full output.
If you use the engine coolant heater before starting your
engine in cold weather, 20
F (
-8
C) or lower, the
heating system will produce warmer air faster to heat the
passenger compartment.
The use of an engine coolant heater also reduces the
time it takes for the engine to reach normal operating
temperature. For more information, see ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
On cool, humid days, use blend mode to keep the
windshield and side windows clear. Use defrost mode to
remove fog or ice from the windshield in extremely
humid or cold conditions. Use defrost mode with the
temperature knob toward the red area and the fan knob
turned all the way clockwise.

3-8
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, turn the
fan knob all the way toward the red area for a few
moments before driving. This helps clear the intake
ducts of snow and moisture, and reduces the chance
of fogging the inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

The use of non
-GM approved hood air deflectors
may adversely affect the performance of the heating
and air conditioning system.
Passenger Compartment Air Filter
Your vehicle is equipped with a passenger compartment
air filter, which filters outside air entering the vehicle.
For information on replacing the filter see ªPassenger
Compartment Air Filterº in the Index.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
ªRetained Accessory Powerº in the Index.
Setting the Clock for Systems with HR and
MN Buttons

control ring allows for more volume compensation at
faster vehicle speeds. Then, as you drive, SCV
