conditioning, and recirculation in
order to heat or cool the vehicle to the desired temperature.
When the AUTO indicator light is on,
the system is in full automatic
operation.
If the air delivery mode, fan speed,

indicator turns off.
To improve fuel efficiency and to cool
the vehicle faster, recirculation may
be automatically selected in warm

activation.
● Open all air vents to allow optimised air distribution in
Automatic mode.
● Set the preselected temperature.
Recommended temperature is
22 °C.
Temperature preselection
Set temperature to the desired value. It is indicated on the display in thetemperature control.
For reasons of comfort, change
temperature only in small increments.
If the minimum temperature Lo is set,
the climate control system runs at
maximum cooling, if cooling A/C is
active.
If the maximum temperature Hi is set,
the climate control system runs at
maximum heating.
Recommended temperature is 22 °C .Note
If A/C is switched on, reducing the
set cabin temperature can cause the
engine to restart from an Autostop or inhibit an Autostop.

Press 4 to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.9 Warning
Driving with recirculation mode for
a prolonged period of time can
make you sleepy. Periodically turn
to the outside air mode for fresh
air.
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the
vehicle occupants to feel drowsy.
In warm and very humid ambient air
conditions, the windscreen may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate V.

Climate control107ServiceFor optimal cooling performance, it is
recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
