Automatic air conditioning

When a button is pressed, the corre-
sponding LED lights up if the system
was switched on at airflow volume
selector wheel (3).
Temperature selectors for left
and right sides of car
The temperature control is
switched on and off at the
rotary knob on the driver's
side:
Left-hand limit position: no heating
effect, maximum cooling output, tem-
perature control off.
As the control is turned to the right,
away from the detent position: tem-
perature control cuts in.
Right-hand limit position (detent):
maximum heating output, temperature
control off (also emergency position if
a fault develops in the electronic tem-
perature control system).
The scales are merely intended as a
guide to the interior temperature. The
selected setting is reached as quickly
as possible and does not normally
need to be adjusted subsequently.
Alter settings by only small amounts
at a time, to avoid undesirable tem-
perature fluctuations.
On/off switch and airflow vol-
ume selector
Position 0: system is switched
off, air intake closed.
Turned to the right as far as first
detent: system switched on, minimum
airflow.
Turned farther to the right: airflow
increases.
Right-hand limit position (detent):
maximum airflow volume (also emer-
gency position if a fault develops in
the electronic blower control system)
Program buttons for air distribu-
tion to left and right sides of car
Automatic air distribution
With only a few exceptions,
this program can be used
in all normal driving condi-
tions.
Depending on actual temperatures,
the air inlets are opened and closed
automatically.
To ensure freedom from fatigue, the
system works according to the warm
feet - cool heat principle.
However, the air emerging from the
facia grilles can be varied separately
in temperature; see next page.
To ensure that this program can oper-
ate effectively, some of the outlet
grilles on the facia and the doors must
be open and the airflow volume selec-
tor should be turned past the first
detent.
Air distribution through all grilles
and outlets – no automatic con-
trol
This program is recommended
in warm weather, for instance,
if extra ventilation or cooling of
the footwell areas is needed.
