Automatic Climate Control
The automatic climate control is
designed to maintain the desired
temperature in the vehicle interior.
Heating, cooling and air distribution
(top, center, bottom) are controlled
automatically. The blower speeds
will be varied automatically
depending on the push button
setting, operating and temperature
conditions.
The automatic climate control is
operational only if the engine is
running.
For adaptation to the weather con
ditions various functions can be
selected with the pushbuttons. Air
outlets 8 — 9 must then be adjusted
as required. Buttons 2 - 6 can be
pressed only individually. The
indicator lights in the individual
buttons come on if the buttons are
pressed and the vehicle lighting is
switched on.
1 Temperature selector wheel
The desired temperature in the
vehicle interior can be set with
the selector wheel.
Normally only one adjustment is
necessary for the entire year.
If required to be altered, only
slight adjustments should be
made to this temperature
setting.
2 “ OFF” button:
Switching off the automatic
climate control.
Simultaneously the fresh air
supply to the vehicle interior is
cut off. This position can be
briefly selected in the case of
odorous or dust annoyances or
when passing through an auto
matic car wash.
3 “ AUTO-LO” button:
Normal vehicle operation.
This setting will provide heating
or cooling of the vehicle’s
interior depending on the
selector wheel setting and the
outside temperature. If heating
is required, the fresh air supply
and the blower will remain in the
off position until the engine
cooling water is slightly warmed
up. Only then will warm air
enter the interior of the vehicle
and be distributed mainly to the
footwell outlets. A small amount
of air is directed to the wind
shield to ensure defogging
under normal weather con
ditions. For the defogging of the
side windows, air can be di
verted from the side outlets 9.
The center outlets 8 remain
closed during heating operation.
If cooling of the interior is
required, the blower will start
immediately regardless of
engine temperature. The air is
routed via center outlets 8 into
the vehicle’s interior and addi
tionally via the side outlets 9.
No air is allowed to flow to the
windshield and to the footwell.
The blower speed will be auto
matically reduced in several
steps in the heating or cooling
cycle as the interior temperature
approaches the preselected
temperature on the temperature
wheel 1.
