temperature is above a specific level. Therefore condensation may form
and drip from under the vehicle.

112Climate controlIf no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
The display will indicate ACON when
cooling is activated or ACOFF when

Air recirculation mode 4Press 4 to activate the air
recirculation mode. The LED in the
button illuminates to indicate
activation.
Press 4 again to deactivate
recirculation mode.9 Warning
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 from inside.
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 s.
Basic settings
Some settings can be changed in the Settings menu in the Info-Display.

Climate control113Air vents
Adjustable air vents At least one air vent must be open
while the cooling is on.
To open the vent, turn the adjuster
wheel towards the bigger W symbol.
Adjust the air amount at the vent
outlet by turning the adjuster wheel.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel towards the smaller W symbol.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.
Maintenance

The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.

114Climate controlAir conditioning regularoperation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service For 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
Note
Refrigerant R-134a contains
fluorinated greenhouse gases.
