Optimum use of automatic climate
control
Optimum use of the automatic climate
control
The following contains notes and recommenda-
tions on optimum use of the dual-zone or 3-zone
automatic climate control.
RYou can switch on climate control by using the
à and¿ orà andÁ buttons.
The indicator lamps in the Ãand
¿ buttons or the ÃandÁ buttons
light up.
RVehicles with 3-zone climate control: in
automatic mode, you can also use the
ñ button to set a climate mode (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
RVehicles with 3-zone climate control: use
the ZONE function to adopt the temperature
settings on the driver's side for the front-
passenger side and the rear compartment as
well. The indicator lamp above the ábut-
ton goes out.
RVehicles with 3-zone climate control: use
the "residual heat" function if you want to heat
or ventilate the vehicle interior when the igni-
tion is switched off. The residual heat function
can only be activated or deactivated with the
ignition switched off.
RIf 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 system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
