body. Therefore, open these vents for maxi-
mum cooling.
AUC Automatic recirculated-air
control/recirculated-air mode
You can respond to pollutants or
unpleasant odors in the immediate
environment by suspending the
supply of outside air. The system then recircu-
lates the air currently within the vehicle. During
AUC operation, a sensor detects pollutants in
the outside air and controls the shut-off auto-
matically.
By pressing the button repeatedly, you can
request three operating modes:
> LED off: outside air flows in continuously.
> Right LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
> Left LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air volume as
required.
The recirculated-air mode should not be used
over an extended period of time, as the air qual-
ity inside the vehicle deteriorates continu-
ously.
<
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
> up to 15 minutes after switching off the
engine
> with engine at operating temperature
> with sufficient battery voltage
> at an outside temperature below 77 7/
25 6
The LED lights up when the function is
switched on.
From radio readiness the interior temperature,
the air volume and the air distribution can be
set.
Switching off automatic climate control
The air volume, the heater and the
cooling function are all switched
off.
You can restart the automatic cli-
mate control by pressing any of its buttons
except the REST button.
Front ventilation
1 Knurled wheels to smoothly open and close
air vents
2 Levers to change the air vent direction
Do not drop any foreign objects into the
vent outlets, otherwise these could be
catapulted outwards and lead to injuries. <
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, for instance, if the interior
has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
