3. When the system is set up for your
comfort level, it is not necessary to
change the settings. You will experi-
ence the greatest efficiency by simply
allowing the system to function auto-
matically.
NOTE:
• It is not necessary to move the
temperature settings for cold or
hot vehicles. The system auto-
matically adjusts the tempera-
ture, mode and fan speed to pro-
vide comfort as quickly as
possible.
• The temperature can be dis-
played in English or Metric units
by selecting the “Display Units
of
Measure
in”
customer-
programmable feature. Refer to
the “Electronic Vehicle Informa-
tion Center (EVIC) — Customer-
Programmable Features” in this
Section.
To provide you with maximum com-
fort in the automatic mode, during
cold start-ups, the blower fan will re-
main on low until the engine warms
up. The fan will engage immediately
if the Defrost mode is selected, or by
changing the front blower knob set-
ting.
Manual Operation Override
This system offers a full complement
of manual override features. The
AUTO symbol in the front ATC dis-
play will be turned off when the sys-
tem is being used in the manual mode.
NOTE:
If not operating in AUTO
mode, the system will not auto-
matically sense the presence of fog,
mist or ice on the windshield. DE-
FROST 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 acti-
vate or deactivate the air conditioning
system. When in A/C mode and the
ATC is set to a cool temperature, de-
humidified 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 hu-
midity, or if rapid cooling is
desired, you may wish to
recirculate interior air by pressing the
Recirculation control button. Recir-
culation mode should only be used
temporarily. A LED will illuminate on
the Recirculation control button when
Recirculation mode is selected. Push
the button a second time to turn off
the Recirculation mode LED and al-
low outside air into the vehicle.
