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 25). Overview of climate control systems
General 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 activate air-recirculation mode only briefly
R activate the "Cooling with air dehumidifica-
tion" function
R activate the windscreen demisting function
briefly, if required
The air-conditioning system/
THERMOTRONIC automatic climate control
regulates the temperature and the humidity
of the vehicle interior and filters undesirable
substances from the air.
The air-conditioning system/
THERMOTRONIC automatic climate control
can only be operated when the engine is run-
ning. 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 155).
Always keep the ventilation flaps behind the
side panelling clear (Y page 136). 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 102).
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 stated in the Service Booklet.
i Vehicles with auxiliary heating:
under
certain environmental conditions, the
residual heat function may be activated
automatically an hour after the key has
been removed in order to dry the automatic climate control. When the automatic cli-
mate control drying function is active, the
blue LED lamp is lit in the rocker switch in
the centre console. The vehicle is then ven-
tilated for 30 minutes.
Vehicles without auxiliary heating:
under certain environmental conditions,
the residual heat function may be activated automatically an hour after the key has
been removed in order to dry the automatic
climate control. The vehicle is then ventila-
ted for 30 minutes. 144

system
Air-conditioning system Below, you can find a number of tips and rec-
ommendations for optimum use of the air-
conditioning system.
R Switch on the air-conditioning system by
turning control knob Aclockwise to the
desired position (except position 0).
R Set the temperature to 22 †.
R Recommendation for avoiding misted
windows at low exterior temperatures
or in rain: switch on the ¿cooling with
dehumidification function (Y page 149).
Set air distribution to ¯and if possible
switch off PandO (Ypage 151).
Deactivate air-recirculation mode e
(Y page 154). Set airflow control
Ato a setting between
3 and 6(Y page 151).
R Recommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3
and 6(Y page 151).
R Recommendation for a constant vehi-
cle interior temperature: set airflow con-
trol Ato a setting between 1and 3
(Y page 151).
R Recommendation for air distribution in
winter: select the Oand¯ settings
(Y page 151).
Recommendation for air distribution in
summer: select the PorP and
¯ settings (Y page 151).
R Only use the "Windscreen demisting" func-
tion briefly until the windscreen is clear
again. Overview of climate control systems
145Climate control

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 If 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
instructions). You will see the current set-
tings of the various climate control func-
tions.
DYNAMIC SELECT button (except
Mercedes-AMG vehicles) You can choose between various drive pro-
grams with the DYNAMIC SELECT button
(Y page 174).
If you have selected drive program E:
R when heating, the electrical heater booster
is deactivated and in the warming-up phase
heat output is reduced
R the rear window heating running time is
reduced
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.
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 171). 146
