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 24). 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
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control
regulates the temperature and the humidity
of the vehicle interior and filters out undesir-
able substances from the air.
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control is only operational when the engine is running.
Optimum operation is only achieved with the
side windows and panorama sliding sunroof
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 137).
Always keep the ventilation flaps behind the
side panelling clear (Y page 120). Otherwise,
the vehicle will not be ventilated correctly. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 90). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. With THERMOTRONIC auto- matic climate control, gaseous pollutants
and odours will also be reduced. A clogged
filter reduces the amount of air supplied to
the vehicle interior. For this reason, you
should always observe the interval for
replacing the filter, which is specified in the Service Booklet. As this depends on envi-
ronmental conditions, e.g. heavy air pollu-
tion, the interval may be shorter than statedin the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed in order to
dry the automatic climate control. The vehi- cle is then ventilated for 30 minutes. 126

R Recommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3
and 6(Y page 133).
R Recommendation for a constant vehi-
cle interior temperature: set airflow con-
trol Ato a setting between 1and 3
(Y page 133).
R Recommendation for air distribution in
winter: select the Oand¯ settings
(Y page 133).
Recommendation for air distribution in
summer: select the PorP and

out of your THERMOTRONIC automatic cli-
mate control.
R Activate climate control using the Ãand
¿ buttons. The indicator lamps in the
à and¿ buttons light up.
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
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. Overview of climate control systems

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 the full climate control out-
put, you can switch off the ECO start/stop
function by pressing the ECO button
(Y page 151). 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.

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 deactivate the "Cooling with air-dehu-
midification" function 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 cooling mode is active. Thisis normal and not a sign that there is a mal-
function. 130

mode
General notes Only THERMOTRONIC automatic climate con-
trol features the "Control climate control
automatically" function.
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,

Problem
Possible causes/consequences and
M
MSolutions The rear window heat-
ing has switched off
prematurely or cannot
be activated. The battery has not been sufficiently charged.
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 You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
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.
The operation of air-recirculation mode is thesame for all control panels.
