Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 34). Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the "demist windscreen" function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. Optimum operation is only achieved when the side windows and the roof
are closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 149).
i Ventilate the vehicle for a brief period
during warm weather. This will speed up the cooling process, and the desired vehicle
interior temperature will be reached more
quickly. i
An hour after the key has been removed,
it is possible that the residual heat function may be activated automatically in order to
dry the air-conditioning system. The vehicleis then ventilated for 30 minutes to dry the air-conditioning system. 140

THERMOTRONIC automatic climate
control
Automatic climate control The following contains instructions and rec-
ommendations to enable you to get the most
out of your THERMOTRONIC automatic cli-
mate control.
R Activate climate control using the Ãand
¿ buttons on the control panel of the climate control. The indicator lamps in
the
à and¿ buttons light up.
R In 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.
R Set the temperature to 22 †.
R Only use the "Windscreen demisting" func-
tion briefly until the windscreen is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or Overview of climate control systems
141Climate control

when in a tunnel. The windows could oth-
erwise mist up, as no fresh air is drawn into
the vehicle in air-recirculation mode.
R Use 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 the ábutton goes out.
R Use 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.
R Vehicles with COMAND Online: 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 Online operating
instructions. You will see the current set-
tings of the various climate control func-
tions.
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
(Y page 160). Operating the climate control system
Switching climate control on/off
General notes When the climate control is switched off, the
air supply and air circulation are also
switched off. The windows could mist up.
Therefore, only switch off climate control
briefly.
i Activate climate control primarily using
the à button (Y page 144). Activating/deactivating X

with air dehumidification function
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 mist up more quickly. Therefore,
only switch off cooling with air dehumidifica-
tion for a short period.
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 cooling mode is active. Thisis normal and not a sign that there is a mal-
function. 142

goes out. The cooling
with air dehumidifica-
tion system cannot be
switched on. Cooling with air dehumidification has been deactivated due to a
malfunction.
X Visit a qualified specialist workshop. Setting climate control to automatic
mode
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. If desired, cooling with
air dehumidification can 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 mist up more quickly. Therefore,
only switch off cooling with air dehumidifica-
tion for a short period.

Possible causes/consequences and
M
MSolutions The rear window heat-
ing has switched off
prematurely or cannot
be activated. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heat-
ing can be activated again. Activating/deactivating air-recircula-
tion mode
General notes If you switch on air-recirculation mode, the
windows can mist up more quickly, in partic-
ular at low temperatures. Only use air-recir-
culation mode briefly to prevent the windows
misting up.
