Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 135).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 90). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly. If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 142).
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci-
fied.
iVehicles with ionization of the interior
air and air filter: in addition to ionization, the
vehicle has an air filter with anti-allergenic
properties that contribute to improved air fil-
tration.
iIt is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey
has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-
tilated for 30 minutes.

Optimum use of automatic climate
control
The following contains notes and recommenda-
tions on optimum use of the dual-zone auto-
matic climate control or 3-zone automatic cli-
mate control.
RYou can switch on climate control by using the
Ãand¿ orà andÁ buttons.
The indicator lamps in the Ãand
¿ buttons or the ÃandÁ buttons
light up.
RVehicles with 3-zone automatic 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 automatic climate
control: use the ZONE function to adopt the
temperature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the á button goes out.
RVehicles with 3-zone automatic climate
control: use the "residual heat" function if
you want to heat or ventilate the vehicle inte- rior when the ignition is switched off. The
residual heat function can only be activated or
deacti
vated 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 (
Ypage 145).

General notes
When the climate control is switched off, the air
supply and air circulation are also switched off.
The windows could fog up. Therefore, switch off
climate control only briefly
Activate climate control primarily using the
à button (
Ypage 132).
In the rear compartment, you can also switch
climate control on and off using the Ãand
^ buttons.
Activating/deactivating
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 140).
XTo activate: press theÃbutton.

up. Airflow and air distribution are set to auto-
matic mode.
XTo deactivate: press the^button.
The indicator lamp in the ^button lights
up.
