Heating, cooling and air distribution
within the vehicle's interior will be
automatically controlled. This is
accomplished with the temperature
selector (1), the pushbuttons (2) and
the fan control buttons (3).
The adjustable air outlets (6) and (8)
can be variably opened and closed, or
moved to direct the flow of air as
desired.
The air flow can be increased or
decreased by rotating controls (5)
and (7).
With the exterior lamps turned on
(except standing lamps), the symbols
on all buttons light up. Each button
shines brighter when depressed.
Notes:
The automatic climate control oper­
ates properly only if all windows and
the sliding roof are closed.
Air outlets (6) and (8) must not all be
closed at the same time.
The automatic climate control removes
considerable moisture from the air
during operation in the cooling mode.
It is normal for water to drip on the
ground through ducts in the middle
area of the underbody.
