0 (Defrost): This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshield
and side window outlets. When selected, the system
automatically turns off recirculation and runs the
air conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation
cannot be selected while in the defrost mode. Do not
drive the vehicle until all the windows are clear.
For professional vehicles, air will be allowed to flow
through the rear outlets. For quicker defrost, press the
AUX button on the front climate control system so that
the light is not lit.
# (Air Conditioning): Press to turn the air
conditioning system on or off and override the automatic
system. When in AUTO, the air conditioning compressor
comes on automatically, as necessary. To avoid window
fogging on rainy and humid days at temperatures above
freezing, run the air conditioning.
The air conditioning system removes moisture from
the air, so a small amount of water may drip under
the vehicle while idling or after turning off the engine.
This is normal.
: (Outside Air): Press to turn the outside air mode
on or off. An indicator light comes on to show it is on.
Air is pulled from outside the vehicle. Pressing
? will
cancel this mode.
? (Recirculation): Press to turn the recirculation
mode on or off. An indicator light below the button
comes on to show that this mode is on. This mode
recirculates and helps to quickly cool the air inside the
vehicle. It can be used to prevent outside air and odors
from entering the vehicle. This mode cannot be selected
while in the defog or defrost modes. If you try to select
the recirculation mode, the indicator light flashes three
times and turns off.
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.
AUX: For vehicles with a rear climate control system,
press to turn the rear climate control fan on for
automatic operation. After the AUX button is pressed,
the indicator light comes on. Press the button again to
turn the auxiliary fan off. See Rear Climate Control
System on page 4‑42.
PASS (Passenger Climate Control): Press to turn the
passenger climate control systems on or off. When the
passenger climate control system is on, the passenger
temperature setting is displayed. The temperature
selected by the front passenger also controls the rear
system air temperature unless the rear seat passengers
select their own comfort setting.
