Comfort Controls
This section tells you how to make your air system
work for you. With these systems, you can control the
ventilation and heating in your vehicle. Your vehicle
also has the flow
-through ventilation system described
later in this section.
Climate Control System
Fan Knob
The left knob selects the force of air you want.
Turn the knob clockwise to increase fan speed and
counterclockwise to decrease fan speed. To turn the
fan off, turn the mode knob all the way counterclockwise
to OFF. In any other setting, the fan will run continuously
with the ignition on. The fan must be on to run the air
conditioning compressor.
Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward
red (clockwise) for warmer air. Turn it toward blue
(counterclockwise) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow. For each setting, set the
temperature to a comfortable setting.

3-3
(Maximum): For maximum cooling use this setting
to recirculate much of the air inside your vehicle and
send it through the instrument panel outlets. The air
conditioning compressor will run automatically in this
setting when it is needed to help cool the air in the
vehicle. Operation in this mode during periods of high
humidity and cool outside temperatures may result in
increased window fogging. If window fogging is
experienced, select the defrost mode.
(Vent): This setting brings in outside air and directs
it through the instrument panel outlets.
(Bi-Level): This setting brings in outside air
and directs it two ways. Some air is directed through
the instrument panel outlets. Most of the air is directed
through the floor ducts and a little to the defrost and
side window vents.
(Floor): This setting sends most of the air
through the ducts near the floor. The rest comes out
of the defroster and side window vents.
(Defog): This setting allows half of the air to go
to the floor ducts and half to the defroster and side
window vents.
(Defrost): This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting when
it is needed to help dry the air in the vehicle. The A/C
indicator light will also be on in the setting.
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioner
compressor. The indicator light above the button will
glow when the air conditioning compressor is running.
You don't have to press the button to run the compressor
in maximum or defrost.
It is normal for the A/C indicator light to come on while
in defrost.
Running the compressor will help reduce vehicle
interior fogging.

3-4 Air Conditioning
On very hot days, open the windows long enough to
let hot, inside air escape. This reduces the time it takes
for your vehicle to cool down, which should help
fuel economy.
For quick cool
-down on very hot days, use the
maximum mode setting with the temperature knob
all the way in the blue area. If this setting is used for
long periods of time, the air in your vehicle may become
too dry. The best cool
-down happens if you start in
one of the other modes and then switch to maximum.
For normal cooling on hot days, use vent with the
temperature knob in the blue area and the A/C button
pressed in. The system will bring in outside air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use bi
-level with the temperature knob in the
middle and the A/C button pressed in. The system will
bring in outside air and direct slightly warmer air to
your lower body. You may notice this temperature
difference more at some times than others.
Heating
On cold days, use floor with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting
Your system has two settings for clearing the front
and side windows. To defrost the windows quickly,
use defrost with the temperature knob all the way
in the red area. To warm passengers while keeping the
windows clean, use defog.

3-5
To defog the side windows, set the right control to
bi
-level and the fan control to the highest setting.
To defog the side windows while using the air
conditioner, set the right control to bi
-level, the fan
control to the highest setting, and press the A/C button.
For both systems, aim the side vents toward the side
windows. For increased airflow to the side vents, close
the center vents.
Rear Window Defogger (If Equipped)
Press the button located
under the air conditioning
button to turn the defogger
on. It will turn itself off
after about 10 minutes.The rear window defogger uses a warming grid to
remove fog from the rear window. It is designed to
clear the center of the rear window first.
If you turn it on again, the defogger will only run for
about five minutes before turning off. You can also turn
it off by pressing the button again.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.NOTICE:
Don't use a razor blade or anything 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.

3-6 Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use vent to direct outside air through
your vehicle. Your vehicle also has the flow
-through
ventilation system.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
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, adjust the
mode knob to floor and the fan to the highest speed
for a few moments before driving off. 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 circulate throughout
your vehicle.

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.
