FRONT: This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts and the side window vents.
The air conditioning compressor will run automatically
in this setting unless the outside temperature is below
40
F (4
C). (Even when the compressor is running, you
can control the temperature.)
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a quick cool
-down on very hot days, use MAX with
the temperature knob and lever 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.
For normal cooling on hot days, use NORM with the
temperature knob and lever in the blue area. 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
-LEV and set the temperature knob to a
comfortable setting. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than others.Heating
On cold days, use HTR with the temperature knob and
lever all the way in the red area. The system will bring
in outside air, heat it and send it to the floor ducts.
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.
Ventilation
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 described later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and side
windows. To defrost the windows quickly, use FRONT with
the temperature knob all the way in the red area.
For maximum defroster performance, set both driver and
passenger temperature controls to the warmest setting.
To warm passengers while keeping the windows clear,
use BLEND.

The amber light indicates the same temperature as
set for the driver.

The red lights indicate a warmer temperature than
that of the driver.

The blue lights indicate a cooler temperature than
that of the driver.
Manual Control
If you prefer to manually control the heating, cooling
and ventilation in your vehicle, you can select airflow
direction, fan speed, outside or recirculated air and air
compressor operation with the following buttons:
AIR FLOW: This control has several settings to control
the direction of airflow when the system is not in AUTO.
To access the various modes available, continue to press
the AIR FLOW rocker button up or down until the
desired mode appears in the display:

WINDSHIELD/FLOOR: This setting directs half
of the air to the floor ducts and half to the defroster
and side window vents.

MID/FLOOR: This setting directs half of the air
through the instrument panel outlets. Most of the
remaining air is directed through the floor ducts and
a little to the defroster and side window vents.
MID: This setting directs air through the instrument
panel outlets.

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.
FRONT: This setting brings in outside air and directs
most of the air through the defrost vent. Some of the air also
goes to the floor ducts and the side window defogger outlets.
The indicator on the button will light and WINDSHIELD
will be lit in the display. The air conditioning compressor will
run automatically in this setting unless the outside
temperature is below 40F (4C).
VENT: This pushbutton turns the air conditioning
compressor on and off. The indicator is lit when the
compressor is turned off. Recirculation is not permitted
when the compressor is off. The system will try to control
the temperature automatically, but without the compressor.
VENT is not permitted in FRONT defrost mode. If the
VENT button is pushed while in FRONT defrost mode,
the indicator will light for one second and then turn off.

3-9
RECIRC: This setting recirculates much of the air
inside your vehicle. This setting is not permitted in
FRONT defrost mode and is only permitted in
WINDSHIELD/FLOOR mode if the compressor is
turned on. The indicator light will be lit when
recirculation is engaged, but will light for one second
and then turn off if selected when not permitted.
Heating (Engine Coolant Heater)
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, press the
FRONT button; set the temperature to 90
F (32
C),
select high fan speed and turn the DUAL button off. To
warm passengers while keeping the windows clear, push
the AIR FLOW button until WINDSHIELD/FLOOR
appears in the display. Select fan speed for comfort and
windshield clearing performance.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window. Press the button to
turn the rear defogger on. It will turn itself off after
about 10 minutes. If you turn it on again, the rear
defogger will only run for about five minutes before
turning off. You can also turn it off by pressing the
button again. The picture above on the left refers to the
defogger button that is found on a Manual Single Zone
Climate Control system or Dual ComforTemp Climate
Control system; the button on the right is found on the
Dual Automatic ComforTemp Climate Control system.

3-32 Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still
tightened to the fender.
Backglass Antenna (If Equipped)
Your AM-FM antenna is integrated with your rear
window defogger, located in the rear window. Be sure
that the inside surface of the rear window is not
scratched and that the lines on the glass are not
damaged. If the inside surface is damaged, it could
interfere with radio reception. Also, for proper radio
reception, the antenna connector at the top
-center of the
rear window needs to be properly attached to the post on
the glass.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the rear defogger grid and affect your radio's
ability to pick up stations clearly. The repairs
wouldn't be covered by your warranty.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.
