Fig. 68 Manual air conditioner: Controls
The rotary controls and switches are used to control the functions. The LED in the corresponding button lights up when the function is switched on.
For a comfortable climate inside the vehicle:
  • In the summer, adjust the temperature to just a few degrees below the outside temperature
  • Do not turn the blower up too high
  • Do not point the air outlets directly at the occupants
Key-coded settings
Certain settings will be automatically stored and assigned to the remote control key in use.
  • Manual air conditioner: Seat heating (driver s side), A/C button.
Adjusting the blower speed
The rotary control -1- can be used to adjust the blower speed in small steps. You should leave the blower on at a low setting to prevent the windows from misting up. To demist the windows, we recommend that you increase the blower speed and set control -3- to .
A/C Switching air cooling* on/off
The air cooling system only works when the blower is switched on. When the air cooling is switched off, the air is neither cooled nor dehumidified. The windows may mist up as a result. The air cooling is switched off automatically at low outside temperatures.
/ Adjusting the temperature
The rotary control -2- can be used to adjust the temperature in small steps.
Adjusting the air distribution
The rotary control -3- can be used to adjust the air distribution.
At the setting, the windscreen and side windows are defrosted or demisted. The air recirculation is switched off, but can be switched on again manually by pressing the button.
The round air outlets in the dashboard can be adjusted link►.
To prevent the front side windows from misting up in wet weather, it s a good idea to open the side air outlets and point them to the side.
Switching air recirculation on/off
In air recirculation mode, the air from the interior of the vehicle is filtered and recirculated. This setting prevents fumes etc. from entering the interior. We recommend switching on the air recirculation mode when driving through a tunnel or in traffic queues ►.
The air recirculation mode is switched off when the control is in the defrost position .
REAR Switching rear window heating on/off
If rear window heating is activated with the ignition switched on, the battery management determines whether or not the battery charge level is sufficient for the rear window heating to be switched on. Otherwise the rear window heating operates when the engine is running, and switches off automatically after about 10 - 20 minutes, depending on the outside temperature.
To switch on the rear window heating permanently, press and hold the REAR button for at least two seconds. This setting will be stored for approximately 15 minutes after the ignition is switched off.
WARNING
For reasons of safety you should not leave the air recirculation switched on for too long. This mode prevents fresh air from entering the vehicle, so the windows can mist over if the air cooling is switched off. Bad visibility can cause an accident.
