automatic climate control
The following contains notes and recommenda-
tions on optimum use of THERMATIC automatic climate control.
R Activate climate control using the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Set the temperature to 22 †.
R Only use the "Windscreen demisting" function
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 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 above the ábutton goes out.
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. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control only operates 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 151).128

Information on using THERMOTRONIC
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 above the
à and¿ buttons light up.
R In automatic mode, you can also use the ñ
button to set a climate mode (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
R Set the temperature to 22 †.
R Only use the "Windscreen demisting" function
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 otherwise mist up as no fresh air is drawn into the vehicle inair-recirculation mode.
R Use the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side and the rear compart-
ment as well. The indicator lamp above the
á button 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 only be activated or deactivated 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. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control only operates 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 151). 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.
i Switch on climate control primarily using
the à button (Y page 132).
In the rear-compartment, you can also switch
climate control on/off using the Ãand^
buttons.

air dehumidification
General notes If you deactivate the "Cooling with air dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can mist up
more quickly. Therefore, only deactivate the
"Cooling with air dehumidification" function
briefly.
The "Cooling with air dehumidification" function
is only available 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 malfunc-
tion. 130
