turning control knob Aclockwise to the
desired position (except position 0).
RSet the temperature to 72 ‡ (22 †).
RRecommendation for avoiding misted
windows at low exterior temperatures
or in rain:switch on the ¿cooling with
dehumidification function (
Ypage 138).
Set air distribution to ¯and if possible
switch off PandO (
Ypage 140).
Deactivate air-recirculation mode e
(
Ypage 143).
Set airflow control Ato a setting between
3 and 6(
Ypage 140).
RRecommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3
and 6(
Ypage 140).
RRecommendation for a constant vehi-
cle interior temperature: set airflow con-
trol Ato a setting between 1and 3
(
Ypage 140).
RRecommendation for air distribution in winter: select the Oand¯ settings
(
Ypage 140).
Recommendation for air distribution in
summer: select the PorP and

ROnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g.
if there are unpleasant outsid e od
ors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RIf you change the settings of the climate
control system, the climate status display
appears for approximately three seconds
at the bottom of the screen in the Audio/
COMAND display (see separate operating

Depending on the configuration, the climate
settings can also be influenced in drive pro-
gram I.
If you have selected drive program Cor S, the
climate settings are not affected.
