3-8 Defogging and Defrosting
On cool, humid days, use defog to keep the windshield
and side windows clear. Use defrost to remove fog or ice
from the windshield in extremely humid or cold
conditions. Use defrost with the temperature knob
toward the red area and the fan control turned all the
way to the right.
Rear Window Defogger
Do not remove the rear window with the rear defogger
on. You may see a discharge spark coming from
the latch area if you remove the window with the
defroster on.
The lines running across the rear window are the rear
window defogger lines. The lines warm the glass.
To turn on the rear
window defogger, press
this button located below
the mode knob.The rear window defogger will only work if the ignition
is in RUN. For best results, clear the window of as much
snow or ice as possible first.
The defogger will shut itself off after several minutes.
If you need additional warming time, press the button
again. You can turn the defogger off at any time by
pressing the button.
If your vehicle is equipped with heated outside mirrors,
the rear window defogger button will also activate the
heated outside mirrors.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.

3-9 Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use outside air to direct outside air
through your vehicle. Air will flow through the
instrument panel outlets.
Your vehicle's ventilation system supplies outside air to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air
inlet grilles, through the vehicle, and out of the air
exhaust valves.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running, unless you have the
recirculation button pressed in. For more information on
the recirculation button, see ªAir Conditioningº earlier
in this section.
Your vehicle has air
outlets in the center and
on the sides of the
instrument panel.
You can move the outlets from side
-to-side or up and
down to direct the flow of air. The driver's and
passenger's side outlets have shut
-off thumbwheels.
Turn the thumbwheels to the left to shut off air flow or
to the right to allow air flow. When you close an outlet,
it will increase the flow of air coming out of any outlets
that are open. The center outlet does not completely shut
off airflow.
Your vehicle also has outlets located on the headliner for
the rear seat passengers.
To use these vents, press on the individual slats to
open the vent. Turn the entire vent in the direction you
want to direct airflow. Push the slats to close them and
block airflow.

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 to the right 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.
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 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 off. See ªRetained
Accessory Power (RAP)º in the Index.

knob clockwise to adjust the SCV. Then, as you drive,
SCV automatically increases the volume, as necessary,
to overcome noise at any particular speed. The volume
level should always sound the same to you as you drive.
If you don't want to use SCV, turn the control all the
way down. Each notch on the control ring allows for
more volume compensation at faster vehicle speeds.

this button to turn on the rear seat audio display on the
main radio. Press it again to turn the rear seat audio
display off.
