Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
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 or THERMOTRONIC automatic climate control regulates the temper-ature and the humidity of the vehicle interior andfilters undesirable substances from the air.
The air-conditioning system or THERMOTRONIC automatic climate control can only be operatedwhen the engine is running. Optimum operation
is only achieved with the side windows and pan- orama sliding sunroof closed.
The "Residual heat" function can only be
switched on or off if the ignition is switched off
(Y page 137).
Always keep the ventilation flaps behind the
side panelling clear (Y page 122). Otherwise the
vehicle will not be ventilated correctly.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 98). This will speed up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. With THERMOTRONIC automatic
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 Book-
let. As this depends on environmental condi-
tions, e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet.
i Vehicles with auxiliary heating:
Under
certain environmental conditions, the resid-
ual heat function may be activated automati-
cally an hour after the ignition key has been
removed in order to dry the automatic climate control. The blue LED on the rocker switch in
the centre console lights up when the active
function to dry the automatic climate control is on. The vehicle is then ventilated for
30 minutes.
Vehicles without auxiliary heating: Under
certain environmental conditions, the resid-
ual heat function may be activated automati-
cally an hour after the ignition key has been
removed in order to dry the automatic climate control. The vehicle is then ventilated for
30 minutes. 128

Air-conditioning system Below, you can find a number of tips and rec-
ommendations for optimum use of the air-con-
ditioning system.
R Switch on the air-conditioning system by turn-
ing 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 dehu-
midification function (Y page 132).
Set air distribution to ¯and if possible
switch off PandO( Ypage 133).
Deactivate air-recirculation mode e
(Y page 135).
Set airflow control Ato a setting between 3
and 6(Y page 134). R
Recommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3and
6 (Y page 134).
R Recommendation for a constant vehicle
interior temperature: set airflow controlA
to a setting between 1and 3(Y page 134).
R Recommendation for air distribution in
winter: select the Oand¯ settings
(Y page 133).
Recommendation for air distribution in
summer: select the PorP and¯
settings (Y page 133).
R Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use the "Air-recirculation mode" function only
briefly, e.g. if there are unpleasant outside
odours or when in a tunnel. The windows
could otherwise mist up as no fresh air is
drawn into the vehicle in air-recirculation
mode.

trol system, the climate status display Overview of climate control systems

THERMOTRONIC automatic climate
control
Automatic climate control The following contains instructions and recom-
mendations to enable you to get the most out of
your THERMOTRONIC automatic climate con-
trol.
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 Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use the "Air-recirculation mode" function only
briefly, e.g. if there are unpleasant outside
odours or when in a tunnel. The windows
could otherwise mist up as no fresh air is
drawn into the vehicle in air-recirculation
mode.
R Use the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side as well. The indicator
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 be switched on or off only with
the ignition switched off.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display; see separate operating
instructions. You will see the current settings of the various climate control functions.
DYNAMIC SELECT button (except
Mercedes-AMG vehicles) You can choose between various drive programs
with the DYNAMIC SELECT button
(Y page 151). 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 set-
tings can also be influenced in drive program I.
If you have selected drive program Cor S, the
climate settings are not affected.
ECO start/stop function During automatic engine stop, the climate con-
trol operates only at a reduced capacity. If you
require the full climate control output, you can
switch off the ECO start/stop function by press-
ing the ECO button (Y page 149). Operating the climate control sys-
