3. When the system is set up for your comfort level, it is
not necessary to change the settings. You will experience
the greatest efficiency by simply allowing the system to
function automatically.
NOTE:
•It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible.
•The temperature can be displayed in U.S. or Metric
units by selecting the US/M customer-programmable
feature. Refer to the “Electronic Vehicle Information
Center (EVIC) — Customer-Programmable Features
(SETUP)” in this section of the manual.
To provide you with maximum comfort in the Automatic
mode, during cold start-ups the blower fan will remain
on low until the engine warms up. The blower will
increase in speed and transition into Auto mode.
Manual Operation
This system offers a full complement of manual override
features.
NOTE: Each of these features operate independently
from each other. If any one feature is controlled manually,
temperature control will continue to operate automati-
cally.
There are seven fixed blower speeds.
Use the outer dial control to regulate
the amount of air forced through the
system in any mode you select. The
blower speed increases as you move
the control clockwise and decreases
when you move the control counter-
clockwise.

The blower fan speed can be set to any fixed speed by
adjusting the blower control outer dial. The fan will now
operate at a fixed speed until additional speeds are
selected. This allows the front occupants to control the
volume of air circulated in the vehicle and cancel the
Auto mode.
The operator can also select the direction of the airflow
by selecting one of the following positions.
Panel ModeAir comes from the outlets in the instrument panel.
Each of these outlets can be individually adjusted to
direct the flow of air. The air vanes of the center outlets
and outboard outlets can be moved up and down or side
to side to regulate airflow direction. There is a shut off
wheel located below the air vanes to shut off or adjust the
amount of airflow from these outlets. Bi-Level Mode
Air comes from the instrument panel outlets, floor
outlets and defrost outlets.
NOTE: In many temperature positions, the BI-LEVEL
mode is designed to provide cooler air out of the panel
outlets and warmer air from the floor outlets.
Floor Mode Air comes from the floor outlets. A slight amount of
air is directed through the defrost and side window
demister outlets.
Mix Mode Air comes from the floor, defrost and side window
demist outlets. This mode works best in cold or
snowy conditions. It allows you to stay comfortable
while keeping the windshield clear.
332 UNDERSTANDING YOUR INSTRUMENT PANEL

Defrost ModeAir comes from the windshield and side window
demist outlets. Use Defrost mode with maximum
temperature settings for best windshield and side win-
dow defrosting. When the defrost mode is selected, the
blower will automatically default to medium-high unless
the blower is controlled manually.
NOTE: While operating in the other modes, the system
will not automatically sense the presence of fog, mist or
ice on the windshield. Defrost mode must be manually
selected to clear the windshield and side glass.
Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the operator
to manually activate or deactivate the air conditioning
system. When in A/C mode and the ATC is set to a cool
temperature, dehumidified air flows through the air
outlets. If Economy mode is desired, press the A/C
button to turn off the A/C mode in the ATC display and
deactivate the A/C system. NOTE:
•If the system is in Mix, Floor or Defrost Mode, the A/C
can be turned off, but the A/C system shall remain
active to prevent fogging of the windows.
•If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed.
Recirculation Control
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the RECIRCULATION control button.
Recirculation mode should only be used temporarily. The
recirculation LED will illuminate when this button is
selected. Push the button a second time to turn off the
Recirculation mode LED and allow outside air into the
vehicle.4
UNDERSTANDING YOUR INSTRUMENT PANEL 333

NOTE:In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in the Floor/Defrost Mix and
Defrost modes to improve window clearing operation.
Recirculation will be disabled automatically if these
modes are selected.
Operating Tips
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases,
turning the air conditioning (pressing the A/C button) on
will clear the fog. Adjust the temperature control, air
direction, and blower speed to maintain comfort. As the temperature gets colder, it may be necessary to
direct air onto the windshield. Adjust the temperature
control and blower speed to maintain comfort. Higher
blower speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by selecting the
DEFROST mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
