Overview of climate control systems
General notes
The THERMATIC automatic climate control is
available with one or two climate control zones. As dual-zone automatic climate control, the
temperature can be regulated separately on the
driver's side and front-passenger side.
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 switch on "Cooling with dehumidification"
R activate the "Windscreen demisting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The "Cooling with dehumidification" function is
available only when the engine is running. Opti- mum climate control is achieved only with the
side windows and roof closed.
The integrated filter filters out most particles of
dust and soot and completely filters out pollen.
It also reduces gaseous pollutants and odours. 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 Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 95). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the key
has been removed depending on various fac-
tors, e.g. the outside temperature. The vehi-
cle is then ventilated for 30 minutes to dry the
automatic climate control. Control panel for THERMATIC automatic climate control

control
Optimum use of automatic climate con-
trol The following contains notes and recommenda-
tions on how best to use THERMATIC automatic
climate control.
R Activate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
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.
DYNAMIC SELECT switch (except
Mercedes-AMG vehicles) You can choose between various drive programs
with the DYNAMIC SELECT switch:
R manual transmission (Y page 141)
R automatic transmission (Y page 141)
If you have selected drive program E:
R during heating, the electrical heater booster
is deactivated and heat output is reduced as a
result
R the rear window heating running time is
reduced If you have selected drive program
C,Sor S+,
the current climate settings are maintained.
ECO start/stop function During automatic engine switch-off, the climate
control operates only at a reduced capacity. If
you require the full climate control output, you
can switch off the ECO start/stop function by
pressing the ECO button (Y page 139). Operating the climate control system
Switching the climate control on/off
General notes When climate control is switched off, the air
supply and air circulation are also switched off.
The windows could mist up. Therefore, switch
off climate control only briefly.
Switch on climate control primarily using the
à rocker switch (Y page 127).
Activating/deactivating X
Turn the key to position 2in the ignition lock
(Y page 133).
X To switch on: set the airflow to level 1or
higher using the Hrocker switch.
X To switch off: set the airflow to level 0using
the H rocker switch. 126
Operating the climate control systemClimate control

Activating/deactivating cooling with air dehumidification
General notes If you deactivate the "Cooling with dehumidification" function, the air inside the vehicle will not be
cooled during warm weather. The air inside the vehicle will also not be dehumidified. The windows
can mist up more quickly. Therefore, deactivate the "Cooling with dehumidification" function only
briefly.
The "Cooling with dehumidification" function is available only when the engine is running. 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. This is normal
and not a sign that there is a malfunction.
Activating/deactivating X
Press rocker switch ¿up or down.
The indicator lamp above the rocker switch lights up or goes out.
Problems with the "Cooling with dehumidification" function Problem
Possible causes/consequences and
M MSolutions The indicator lamp above
rocker switch
¿ remains off. The
"Cooling with dehumidi-
fication" function can no
longer be activated via
the multimedia system
(Y page 289). The cooling with dehumidification function has been deactivated due
to a malfunction.
X Consult a qualified specialist workshop. Setting climate control to automatic
mode
General notes In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature of the dispensed air, the airflow and the air dis- tribution.
During automatic controlling, the "Cooling with
air dehumidification" function is activated.
The system automatically detects whether the
soft top is open or closed and automatically
adjusts the air settings depending on the soft
top status. Automatic control X

Activate the "Cooling with air dehumidifica-
tion" function with the ¿rocker switch.
X Switch on automatic mode using the Ã
rocker switch.
X If the windows continue to mist up, activate
the "Windscreen demisting" function using
the ¬ rocker switch. i
You should select this setting only until the
windscreen is clear again.
Windows misted up on the outside X
Switch on the windscreen wipers.
X Switch on automatic mode using the Ã
rocker switch.
i If you clean the windows regularly, they do
not mist up as quickly. Rear window heating
General notes The rear window heating has a high current
draw. You should therefore switch it off as soon
as the window is clear. It otherwise switches off
automatically after several minutes.
If the battery voltage is too low, the rear window heating may switch off.
Switching the sound on/off X
Turn the key to position 2in the ignition lock
(Y page 133).
X Press the ¤rocker switch up or down.
The indicator lamp above the ¤rocker
switch lights up or goes out.
Problems with the rear window heating Problem
Possible causes/consequences and
M MSolutions The rear window heating
has switched off prema-
turely or cannot be acti-
vated. 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 heating
can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can also temporarily deactivate the flow of
fresh air manually if unpleasant odours are
entering the vehicle from outside. The air already inside the vehicle will then be recircula-
ted.
If you activate air-recirculation mode, the win-
dows can mist up more quickly, particularly at
low outside temperatures. Use air-recirculation
mode only briefly to prevent the windows from
misting up. Operating the climate control system
