AC operating units
The operating units of the THERMATIC two-zone auto-
matic air conditioning and the THERMOTRONIC three-
zone comfort automatic air conditioning have been
completely redesigned. Modifications have been
made to the styling and to the controls.
The new operating units are modular in design.
The rocker switches at the bottom of the operating
units control the following functions:
• Interior temperature for driver and front passenger
• Blower output in various stages
• Air distribution in the desired areas of the vehicle
• Air flow via various ventilation modes, "Diffuse",
"Medium" and "Focussed"
(with THERMOTRONIC)
i Note
Each ventilation mode can only be selected in
automatic mode.

The ventilation modes allow the air flow and air distri-
bution to be adjusted more specifically.
• "Diffuse" air flow: The air flow is kept relatively low
and is not directed at the occupants if possible.
• "Medium" air flow: The air flow is approximately the
same as in conventional automatic mode.
• "Focussed" air flow: The air flow is kept slightly
higher and more focussed.
In the middle across the full width of each operating
unit is the display, where the settings of the automatic
air conditioning are shown.
