Notes on using 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 †).
118Overview of climate control systems
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 131).

The windows could fog up. Therefore, switch off
climate control only briefly
iActivate climate control primarily using the
à button (Ypage 120).

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.
Switching on/off
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
has a delayed switch-off feature.
Problems with the "Cooling with air dehumidification" function
ProblemPossible causes/consequences and MSolutions
The indicator lamp in the
¿button flashes
three times or remains
off. The "Cooling with air
dehumidification" func-
tion cannot be switched
on.Cooling with air dehumidification has been deactivated due to a mal-
function.

Setting climate control to automatic
General notes
In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
The "Cooling with air dehumidification" function
is activated automatically in automatic mode.

Defrosting the windshield
You can use this function to defrost the wind-
shield or to clear a fogged up windshield or side
windows on the inside.
Switch off the "Windshield defrosting" function
as soon as the windshield is clear again.
XTurn the SmartKey to position 2in the ignition
lock (Ypage 127).
XTo activate: press the¬button.
