from entering.
Touching 4 deactivates air
recirculation. Press AUTO to return to
automatic operation; recirculation
runs automatically as needed.
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.
Remote heating and cooling
Operated by pressing O on the
electronic key.
The climate control system will default
to an appropriate heating or cooling
mode and the rear window heating
will turn on in the event of cold outside temperatures.

Climate control145Air vents
Adjustable air vents At least one air vent must be open
while cooling is on.
Direct the flow of air by tilting and
swivelling the slats.
The airflow may be restricted if the
slats are directed towards the
windows. Keep the air vents open for proper system performance.
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.

146Climate controlMaintenanceAir intake
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.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Additionally, an active carbon filter
reduces odours.
Air conditioning regular
operation
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
