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. 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 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). Operating the climate control system
Switching the 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.

Activating/deactivating cooling with
air dehumidification
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.

X Visit a qualified specialist workshop. Setting climate control to automatic
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,
only deactivate the "Cooling with air-dehu-
midification" function briefly.

screen and the side windows.
i You should only select the "Windscreen
demisting" function until the windscreen is clear again.

on/off
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 activate air-recirculation mode, the win-
dows can mist up more quickly, in particular
at low temperatures. Only use air-recircula-
tion mode briefly to prevent the windows
misting up.
The operation of air-recirculation mode is the same for all control panels.

General notes The residual heat function is only available
with THERMOTRONIC automatic climate con-
trol.
It is possible to make use of the residual heat of the engine to continue heating the vehicle
for approximately 30 minute safter the engine
has been switched off. The heating time
depends on the set interior temperature.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
i You cannot use the ventilation to cool the
vehicle interior to a temperature lower than the outside temperature. Operating the climate control system
