56 GETTING TO KNOW YOUR VEHICLE
NOTE:
The system uses R-1234yf (refrigerant) which
does not pollute the environment in the event of
accidental leakage. Under no circumstances is
the use of R-134a (refrigerant) allowed.
Rapid Window Demisting (MAX-Defrost Function)
Push the MAX-defrost button to activate (LED
on) the windshield and side window demisting
function.
The Climate Control system carries out the
following operations:
Turns on the air conditioning compressor when
environmental conditions are suitable
Turns air recirculation off
Sets blower fan to the maximum speed and
displays the fan speed (Blower Control Indi-
cator LED illuminated)
Directs air flow to windshield and front side
window diffusers
Activates the heated rear window defrost
Activates the heated windshield (if equipped)
When the function is activated, the AUTO button
LED turns off. With the function activated, the
only possible manual adjustments are pushing
the A/C control button, adjusting the fan speed
and turning the heated rear window off.
When the Recirculation Control or AUTO buttons
are pushed, the Climate Control system will
deactivate the Front Defrost (MAX-DEF) func-
tion.
Selecting the footwell/windshield or only wind-
shield distribution activates the Climate Control
system compressor and the air recirculation is
set to outside air intake.
This logic guarantees optimum visibility at the
windows. Max-defrost is also available in
manual mode.
Climate Control System Compressor
Push the A/C Control button to activate/deacti-
vate the compressor (activation is indicated by
the LED on the button turning on).
The system remembers that the compressor
has been turned off, even after the engine has
stopped.
Pushing the A/C button will stop AUTO mode
(AUTO LED will turn off). To restore automatic
control of compressor, push the AUTO button
again.
NOTE:
With the compressor off, air cannot be intro-
duced to the passenger compartment with a
temperature lower than the outside temperature.
Under certain environmental conditions,
windows could fog rapidly since the air is not
dehumidified.
Turning Off The Climate Control System
Push the ON/OFF button.
With the Climate Control system off:
Air recirculation is on, isolating the passenger
compartment from the outside
The A/C compressor is off
The blower is off
The heated rear window can be activated/
deactivated
NOTE:
The Climate Control unit stores the temperatures
set before the system was turned off and restores
them when one of the following knobs/buttons are
pushed:
