Automatic climate control *
Air conditioning
The air is cooled and
dehumidified and —
depending on the temperature setting —
warmed again. Depending on the
weather, the windshield may fog over
briefly when the engine is started. You
can reduce condensation forming on
the windows by switching on the air
conditioning.
During air conditioning condensa-
tion forms, which then exits under
the vehicle. That traces of water on the
ground are therefore normal.

Maximum cooling
You will get maximum cool-
ing capacity using this pro-
gram if the engine is running and the
outside temperature is above approx.
41
7/56.
The temperature display 9 jumps to
60
7/166, the system switches over
to the recirculated-air mode, and the
maximum air supply flows from the ven-
tilation grills only. That is why you need
to keep these open if you select this
program.
AUC Automatic recirculated-air
control
You can respond to
unpleasant odors or pollut-
ants in the immediate environment by
shutting off the supply of outside air.
The system then recirculates the air
currently within the vehicle. In AUC
operating mode, a sensor detects pol-
lutants in the external air and controls
the shut-off automatically.
Press the button repeatedly to run
through the following control sequence
> Indicator lamps off: outside air supply
operational
> Left indicator lamp on, AUC mode:
the system recognizes pollutants in
the outside air and blocks the flow of
air when necessary. The system then
recirculates the air currently within
the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
> Right-hand indicator lamp on: the
outside air supply into the vehicle is
completely blocked. The system then
recirculates the air currently within
the vehicle.
With the button on the steering wheel
you can also switch between Off and
recirculated-air mode or AUC and recir-
culated-air mode, refer to page
23 .
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.

Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear win-
dow defroster switches off automati-
cally.
Residual heat
Press button when the motor
is switched off, but warm.
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.
This function may be activated when
the outside temperature is below
approx. 59
7/156, the engine is at
operating temperature, and the battery
is adequately charged. The LED on the
button will light up when all conditions
have been met.
