Climate control151Temperature preselection
Set the preselected temperatures
separately for driver and front
passenger to the desired value using
the left and right rotary knob. The knob on the passenger side changes
the temperature for the passenger
side. The knob on the driver's side
changes the temperature for the
driver's side or for both sides
depending on activation of
synchronisation SYNC.
Recommended temperature is 22 °C .
Temperature is indicated in displays
beside the rotary knobs and as pop-
up in the Info Display.
If the minimum temperature Lo is set,
the climate control system runs at
maximum cooling, if cooling A/C is
switched on.
If the maximum temperature Hi is set,
the climate control system runs at maximum heating.

and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.

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
● cabin air filter check
