to detect and rectify malfunctions and to opti-
mize vehicle functions. Most of these data are
volatile and processed only in the vehicle itself.
Only a small part of the data is stored in event or
malfunction memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees or third parties. Services can include
repair services, maintenance processes, war-
ranty cases and quality assurance measures.
The data is read out via the legally prescribed
diagnostics connection in the vehicle. The rele-
vant offices in the service network or third par-
ties collect, process and use the data. These
data document the vehicle's technical states,
are used to help in finding malfunctions and
improving quality and are sent to the manufac-
turer where necessary. In addition, the manu-
facturer is subject to product liability. The man-
ufacturer needs technical data from vehicles for
this purpose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com-
fort and infotainment functions yourself as part
of the s
elected equipment.
These include, for example:
Rmultimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
Raddress book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
Rnavigation destinations that have been
entered
Rdata about using Internet services
These data can be saved locally in the vehicle or are located on a device that you have connected
to the vehicle. If this data is saved in the vehicle,
you can delete it at any time. These data are sent
to third parties only at your request, particularly
when you use online services in accordance with
the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the piece of equipment in ques-
tion, these can include, for example:
Rseat and steering wheel position settings
Rsuspension and climate control settings
Rcustom settings such as interior lighting If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile
end device to the vehicle. You can control this by
means
of th
e control elements integrated in the
vehicle. The smartphone's picture and sound
can be output via the multimedia system. Spe-
cific items of information are also sent to your
smartphone.
Depending on the type of integration, this can
include:
Rgeneral vehicle information
Rposition data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
There is no additional interaction between the
smartphone and the vehicle, particularly active
access to vehicle data. The type of additional
data processing is determined by the provider of
the app being used. Whether you can configure settings for it and, if so, which ones, depends on
the app and your smartphone's operating sys-
tem.
Service provider
Wireless network connection
If your vehicle has a wireless network connec-
tion, data can be exchanged between your vehi- cle and other systems. The wireless network
connection is made possible by the vehicle's
own transmitter and receiver or by mobile devi-
ces that you have brought into the vehicle (e.g.
smartphones). Online functions can be used via
this wireless network connection. These include
online services and applications/Apps provided
by the manufacturer or other providers.
Services provided by the manufacturer
In the case of the manufacturer's online serv-
ices, the manufacturer describes the functions
in a suitable place and the associated informa-
tion subject to data protection legislation. Per-
sonal data can be used in order to provide online
services. The data exchange for this takes place
via a secure connection, e.g. with the manufac-turer's IT systems intended for the purpose. Col-
lecting, processing and using personal data
beyond the provision of services is permitted
only on the basis of a statutory permit or decla-
ration of consent.

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.

matic climate control or 3-zone automatic cli-
mate control.
RYou can switch on climate control by using the
Ãand¿ orÃ 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).
