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 recirculates the air currently within the
vehicle. During AUC operation, a sensor
detects pollutants in the outside air and con-
trols the shut-off automatically.
By pressing the button repeatedly, you can
request three operating modes:
> LED off: outside air flows in continuously.
> Left LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
> Right 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.
Switching on residual heat utilization
Pressing the right side switches on the residual
heat utilization when the following conditions
are met:
> up to 15 minutes after switching off the
engine
> with the engine at operating temperature
> with sufficient battery voltage
> at an outside temperature below 77 7/
25 6
REST appears on the display of the automatic
climate control when the residual heat utiliza-
tion is switched on.
From radio readiness the interior temperature,
the air volume and the air distribution can be
set.
If the conditions for the residual heat utili-
zation are met, no display appears.
<
Switching off residual heat utilization
You can select the lowest blower speed by
pressing and holding the left side. Pressing
again switches off the residual heat utilization.
REST disappears from the display of the auto-
matic climate control.
Switching off automatic climate control
You can select the lowest blower
speed by pressing and holding the
left side. Pressing again switches
off the automatic climate control. The air vol-
ume, the heater and the cooling function are all
switched off.
You can switch on the system again by pressing
any button of the automatic climate control.
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
air vents, otherwise these could be cata-
pulted outwards and lead to injuries. <
