A congenial climate

rently within the vehicle. AUC executes this
function automatically.

Press the button repeatedly to run through
the following control sequence:

Indicator lamps off: outside air flows
into the vehicle continuously

Right indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required.
Depending upon air quality require-
ments, in the automatic mode the sys-
tem alternates between its outside-air
and recirculated-air modes

Left indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is continuously blocked.

If condensation starts to form on the
inside window surfaces during opera-

tion 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 a longer period of time, as the air
quality inside the vehicle deteriorates con-
tinuously.

Residual heat mode

If you press this button with the
engine switched off, the system
uses the warmth stored in the
engine to heat the interior, for
instance, while the vehicle is

stationary at a school to pick up a child.
You can adjust the automatic climate con-
trol settings as of ignition key position 2.

Provided that the engine has warmed to its
normal operating temperature and the bat-
tery is charged, you can use this function
for up to 15 minutes after switching off the
ignition. The LED within the button lights up
to confirm compliance with both of these
conditions.

The air volume, the heater and
