temperature.
The automatic climate control achieves this
temperature as quickly as possible, if needed
by using the maximum cooling or heating ca‐
pacity, and then keeps it constant.
Do not rapidly switch between different tem‐
perature settings. Otherwise, the automatic cli‐
mate control will not have sufficient time to ad‐
just the set temperature.
Cooling function
The car's interior can only be cooled with the
engine running.
Press button.
The air will be cooled and dehumidified and,
depending on the temperature setting,
warmed again.
Depending on the weather, the windshield and
side windows may fog up briefly when the en‐

ops that exits underneath the vehicle.
Maximum cooling Press button.
The system is set to the lowest tem‐
perature, optimum air flow and air circulation mode.
Air flows out of the vents to the upper body re‐
gion. The vents need to be open for this.
The function is available above an external
temperature of approx. 32 ℉/0 ℃ and with the
engine running is indicated.
Adjust air flow with the program active.
AUTO program Press button.
Air flow, air distribution and tempera‐
ture are controlled automatically.
Depending on the selected temperature,
AUTO intensity program and outside influen‐
ces, the air is directed to the windshield, side
windows, upper body, and into the footwell.
The cooling function, refer to page 168, is
switched on automatically with the AUTO pro‐
gram.
At the same time, a condensation sensor con‐
trols the program so as to prevent window
condensation as much as possible.Seite 168ControlsClimate control168

within the vehicle.
Press button repeatedly to select an
operating mode:▷LEDs off: outside air flows in continuously.▷Left LED on, automatic recirculated-air
control: a sensor detects pollutants in the
outside air and shuts off automatically.▷Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is per‐
manently blocked.
With constant recirculated-air mode, the air
quality in the car's interior deteriorates and the
fogging of the windows increases.
If the windows are fogged over, switch off the
recirculated-air mode and press the AUTO
button on the driver's side to utilize the con‐
densation sensor. Make sure that air can flow
to the windshield.
