Optimum use of 3-zone automatic cli-
mate control
Automatic climate control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your automatic climate control.
RActivate climate control using the Ãand
¿ buttons on the control panel of the
climate control. The indicator lamps in
the à and¿ buttons light up.
RIn automatic mode, the ñbutton on the
climate control panel may be used to addi- tionally adjust the airflow (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
RSet the temperature to 72 ‡ (22 †).
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 outside odors 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.
138Overview of climate control systems
Climate control

RUse the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp in theábutton goes out.
RUse the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac-
tivated with the ignition switched off.
RVehicles with COMAND: if you change the
settings of the climate control system, the
climate status display appears for three
seconds at the bottom of the screen in the
COMAND display. See also the separate
COMAND operating instructions. You will
see the current settings of the various cli-
mate control functions.
ECO start/stop function
During automatic engine switch-off, the cli-
mate control only operates at a reduced capa-
city. If you require full climate control capa-
city, the ECO start/stop function can be
deactivated by pressing the ECO button
(
Ypage 156).

Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
