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: R
switch off climate control only briefly R
switch on air-recirculation mode only briefly R
switch on the cooling with air dehumidifica-
tion function R
activate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The "Cooling with air dehumidification" function
is only available when the engine is running.
Optimum climate control is only achieved with
the side windows and roof closed.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated ( Y
page 134). The integrated filter filters out most particles 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 condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Maintenance Book-
let.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature ( Y
page 91). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the Smart-
Key has been removed depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the automatic climate control.

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, 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 it is in cooling mode. This is normal
and not a sign that there is a malfunction.
Activating/deactivating X
Press the Z rocker switch up or down.
The indicator lamp above the rocker switch lights up or goes out.
Problems with the "Cooling with air dehumidification" function Problem
Possible causes/consequences and P Solutions
The indicator lamp above
the Z rocker switch
remains off. The cooling
with air dehumidification
function cannot be acti-
vated via the multimedia
system any longer
( Y
page 273). Cooling with air dehumidification has been deactivated due to a mal-
function. X
Visit a qualified specialist workshop.
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.
During automatic controlling, the "Cooling with
air dehumidification" function is activated.

tion lock ( Y

MEDIUM medium airflow, standard setting
DIFFUS El ow airflow, slightly warmer and draft-
free settingX
To set: set the climate mode using the mul-
timedia system ( Y
page 272).
Setting the temperature Dual-zone automatic climate control: different
temperatures can be set for the driver's and
front-passenger sides. X
Turn the SmartKey to position H in the igni-
tion lock ( Y

To increase or reduce: press rocker switch

The climate control system switches to the
following functions: R
high airflow R

i If necessary, the "Cooling with air dehumid-
ification" function is activated. In this case,
the indicator lamp above the Z rocker
switch remains switched off. X
To switch off: press rocker switch d up or
down.
The indicator lamp above the d rocker
switch goes out. The previously selected set-
tings are restored. Air-recirculation mode
remains deactivated.
Defrosting the windows
Windows fogged up on the inside X
Activate the "Cooling with air dehumidifica-
tion" function with the Z rocker switch.X
Switch on automatic mode using the X
rocker switch. X
If the windows continue to fog up, activate the
"Windshield defrosting" function using the
d rocker switch. i You should only select this setting until the
windshield is clear again.
Windows fogged up on the outside X
Activate the windshield wipers. X
Switch on automatic mode using the X
rocker switch.
i If you clean the windows regularly, they do
not fog up so quickly.
Rear window defroster
General notes The rear window defroster has a high current
draw. You should therefore switch it off as soon
as the rear window is clear. Otherwise, the rear
window defroster switches off automatically
after several minutes.
If the battery voltage is too low, the rear window
defroster may switch off.
Activating/deactivating X
Turn the SmartKey to position H in the igni-
tion lock ( Y
page 132). X
Press rocker switch l up or down.
The indicator lamp above rocker switch l
lights up or goes out.
Problems with the rear window defroster Problem
Possible causes/consequences and P Solutions
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The battery has not been sufficiently charged. X
Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window defroster
can be activated again.
Switching air-recirculation mode
on/off
General notes
You can also temporarily deactivate the flow of
fresh air manually if unpleasant odors are enter-
ing the vehicle from outside. The air already
inside the vehicle will then be recirculated. If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.Operating the climate control systems 127
