Heating, cooling and air dis­
tribution within the vehicle's in­
terior will be automatically con­
trolled. This is accomplished with
the temperature selector (1), the
pushbuttons (2) and the fan con­
trol 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
operates properly only if all win­
dows 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.
