Auxiliary heating and ventilation
Usage
Decrease the temperature
Increase temperature
The auxiliary heater heats the vehicle interior and the
engine.
The temperature can also be set using two fin-
gers in the progress bar under the temperature set-
ting area.
The auxiliary ventilation makes it possible to supply
fresh air to the vehicle interior when the engine is
switched off. As a result, the interior temperature is
lowered, e.g. when the vehicle is parked in the sun.
The rear temperature can also be set on the dis-
play in the centre console at the rear.
With a temperature setting outside of the number
range, one of the following icons will be displayed in
