Recirculation
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. The
recirculation indicator will illuminate when this button is
selected. Push the button a second time to turn off the
Recirculation mode and allow outside air into the vehicle.
NOTE: In cold weather, use of Recirculation mode may
lead to excessive window fogging. The recirculation
feature may be unavailable (soft button greyed out) if
conditions exist that could create fogging on the inside of
the windshield. On systems with Manual Climate Con-
trols, the Recirculation mode is not allowed in Defrost
mode to improve window clearing operation. Recircula-
tion will be disabled automatically if this mode is se-
lected. Attempting to use Recirculation while in this
mode will cause the LED in the control button to blink
and then turn off.
Automatic Temperature Control (ATC)
Automatic Operation
1. Press the AUTO hard-key or soft-key button on the
Automatic Temperature Control (ATC) Panel.
2. Next, adjust the temperature you would like the
system to maintain by adjusting the driver and pas-
senger temperature hard or soft control buttons. Once
the desired temperature is displayed, the system will
achieve and automatically maintain that comfort level.
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 automatically.
