Dual-zone automatic climate control
The following contains notes and recommen-
dations on optimum use of dual-zone climate
control.
RActivate climate control using the Ã
rocker switch. The indicator lamp above
the à rocker switch lights up. The "Cool-
ing with air dehumidification" function is
not activated automatically in automatic mode. If necessary, activate this function
(
Ypage 142).
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.

Problems with the "Cooling with air dehumidification" function
ProblemPossible causes/consequences andMSolutions
The indicator lamp over
the¿ rocker switch
flashes three times or
remains off. The cool-
ing with air dehumidifi-
cation function can
also no longer be acti-
vated using Audio 20 or
COMAND (see the sep-

Setting climate control to automatic
General notes
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. The "Cooling with air
dehumidification" function must be activated
manually in automatic mode. If necessary,
"Cooling with air dehumidification" can also
be deactivated.
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.
Automatic control
XTurn the SmartKey to position 2in the igni-
tion lock (
Ypage 153).
XSet the desired temperature using the
w rocker switch on the front control
unit.
or
XSet the desired temperature using
Audio 20 or COMAND (see the separate
operating instructions).
XTo activate: press rocker switch Ãup
or down.
The indicator lamp above the Ãrocker
switch lights up.
XTo switch to manual operation: press the
H rocker switch up or down.
or
XSet the airflow using Audio 20 or COMAND
(see the separate operating instructions).
or
XPress the top or bottom section of the _
rocker switch.
or
XSet the air distribution using Audio 20 or
COMAND (see the separate operating
instructions).

In automatic mode, if you adjust the airflow or
air distribution manually, the indicator lamp
above theÃrocker switch goes out. The
function which has not been changed man-
ually, however, continues to be controlled

tion switches back to automatic mode, the
indicator lamp above the Ãrocker switch
lights up again.

Rear window defroster
General notes
The rear window defroster has a high current draw. You should therefore switch it off as
soon as the rear window is clear. Otherwise,
the rear window defroster switches off auto-
matically after several minutes.

dow defroster may switch off.

Problems with the rear window defroster
ProblemPossible causes/consequences andMSolutions
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated.The battery has not been sufficiently charged.
XSwitch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.

defroster can be activated again.
Switching air-recirculation mode
on/off
General notes
You can also temporarily deactivate the flow
of fresh air manually if unpleasant odors are
entering the vehicle from outside. The air
already inside the vehicle will then be recir-
culated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
Switching on/off
