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.
Climate control can only be operated when the
engine is running. Optimum operation is only
achieved with the side windows and roof closed.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 120).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 88). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
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.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.
iIt is possible that the residual heat function
may be activated automatically an hour after
the SmartKey is removed. The vehicle is then
ventilated for 30 minutes to dry the automatic
climate control.

Optimum use of automatic climate
control
Climate control system
Below, you can find a number of notes and rec-
ommendations to help you use climate control
optimally.
RActivate climate control using the Ãand
¿ buttons. The indicator lamps above the
à and¿ buttons light up.
RIn automatic mode, you can also use the ñ
button to set the climate mode (FOCUS,
MEDIUM or DIFFUSE). The MEDIUM level is
recommended.
RSet the temperature to 72 ‡ (22 †).
Overview of climate control systems115
Climate control
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.
RUse 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.
RVehicles with 3-zone automatic climate con-
trol: 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.
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.
ECO start/stop function
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 127).

trol
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
iActivate climate control primarily using the
à button (Ypage 117).
Activating/deactivating
XTurn the SmartKey to position 2in the ignition
lock (Ypage 123).

Switching cooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will not
be cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up more
quickly. Therefore, deactivate the cooling with air-dehumidification function only 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 it is in cooling mode. This is normal
and not a sign that there is a malfunction.
Activating/deactivating
XTo activate: press the¿button.
The indicator lamp in the ¿button lights up.
XTo deactivate: press the¿button.
The indicator lamp in the ¿button goes out. The "Cooling with air dehumidification" function
