Automatic Climate Control
4 “ AUTO-HI” button:
Fast heating or cooling of
vehicle interior.
Air conditioning, air distribution
and blower control are the same
as in position “3” “ AUTO-LO” .
The blower, however, operates
at a higher speed.
5 “ BI-LEVEL” button:
Forfogged-up windows.
During heating and cooling op­
erations air is channelled to the
windshield and to the footwell.
During the cooling operation
air also enters via the center
swivelling outlets 8.
The vehicle interior is cooled
practically free of draft with
more air being blown into the
footwell. The blower then oper­
ates at a higher speed than
“AUTO-LO” .
We recommend this position
at low ambient temperatures.
“ DEF” button:
For iced-up windows.
Independent of the position of
the temperature selector wheel
air heated to maximum tem­
perature is channelled to the
windshield.
For the side windows, open
swivelling outlets 9.
Refrigerant compressor switch:
Switching the air conditioning
compressor on and off.
The compressor can be
switched off completely in the
positions “AUTO-LO” and
“AUTO-HI” , e. g. if no cooling
is required because of low
ambient temperatures (fuel
economy).
Fresh air is supplied to the
footwell if the refrigerant com­
pressor is switched off while
the system is working in the
cooling mode.
Fresh air enters the vehicle through
the openings in front of the wind­
shield (keep free of snow) and is
emitted through the ventilation
openings below the rear window
if the side windows are closed. Do
not cover up ventilation openings
with clothes etc.
Important!
In order to keep the air condi­
tioning section of the climate
control system in good working
condition at all times, it is
necessary to operate the A /C com­
pressor briefly at least once a
month even during the seasons it
is normally not required. Switch
compressor switch to “ ON” and
depress “ AUTO-LO” or “ AUTO-HI”
button. Make sure that the ambient
temperature is above 36° F (2° C)
since the A /C compressor will
not operate below this temperature.
