Warm feet and a cool head:
stratified interior air temperature
for fatigue-free driving
The air emerging from the facia and
door grilles can be varied in tempera-
ture (except when maximum cooling is
required):
Knurled turn to right – warmer
wheel 1 turn to left – cooler.
Micro-filter
Fresh air is drawn in through a micro-
filter. This filters out up to 100
X of all
pollen and up to 60 X of dust particles
in the air.
Change the filter at the car's regular
servicing intervals. If airflow is notice-
ably lower than usual, this may indi-
cate that the filter should be renewed
earlier.
Press the button: When the telltale
light is on, the heated rear window is
operating at full heat output (rapid
demisting).
When the telltale light goes out, the
heated rear window has switched
over automatically to a low rating in
order to save power. It cuts out com-
pletely after about 20 minutes unless
switched off previously.
If necessary, press the button again:
This will start a new rapid demisting
cycle.
To switch off: If the telltale light is on,
press the button.
Whenever the engine is restarted, the
heated rear window has to be
switched on again if still required.
