When the rear window de-
froster is activated, the indica-
tor lamp comes on. The rear window
defroster switches off automatically.

Residual heat mode

The heat which is stored in
the engine is utilized for
heating the interior when the engine has
been switched off (while waiting at a
railroad crossing, for instance). In igni-
tion key position 1, you can alter the
settings of the automatic climate con-
trol. In ignition key position 0, the sys-
tem automatically directs heated air to
the windshield, side windows and foot-
wells.
This function may be activated
when the outside temperature is
below approx. 597 (156), the engine
is at operating temperature, and the
battery is adequately
required.<
Draft-free ventilation
You can adjust the blower controls for
the upper body area to select the opti-
mum airflow rates and directions for
your personal requirements:
Use rotary dial 1 to open and close the
airflow through an infinitely-variable
range. You can also use the levers 2 to
change the direction of the airflow.
Set the outlets so that the air flows past
you and does not flow directly on you.
Rotary dial 3 allows you to temper the
air flow from these outlets by adding
heat or cooling as desired:
Turn toward blue – colder
Turn toward red – warmer
charged.<
Rear passenger area ventilation
Rotary dial 1 opens the outlets in an in-
finitely-variable range. You can vary the
temperature of the air as it flows out us-
ing rotary dial 3 in the same manner as
for the front rotary dial.
You can change the direction of the air
flow with levers 2.
