R Operating state

nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, such as:
R Operating states of system components (e.g.
fill levels, battery status, tire pressure)
R Status messages concerning the vehicle or its
individual components (e.g. wheel rpm/
speed, deceleration, lateral acceleration, indi- cation of whether seat belts are fastened)
R Malfunctions and defects in important system
components (e.g. lights, brakes)
R Information about events leading to vehicle
damage
R System responses in special driving situa-
tions (e.g. air bag deployment, intervention of
stability control systems)
R Ambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit
function, this data is used by manufacturers to
detect and rectify malfunctions and to optimize vehicle functions. Most of this data is volatile
and processed only in the vehicle itself. Only a
small part of the data is stored in event or mal-
function memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees (e.g. workshops, manufacturers) or
third parties (e.g. breakdown services). Services
can include repair services, maintenance pro-
cesses, warranty cases and quality assurance
measures. The data are read out via the con-
nection for the diagnostics connection in the
vehicle, which is required by law. The relevant
offices in the service network or third parties
collect, process and use the data. This data
documents the vehicle's technical states, is
used to help in finding malfunctions and improv-
ing quality and is sent to the manufacturer
where necessary. In addition, the manufacturer is subject to product liability. The manufacturerneeds technical data from vehicles for this pur-
pose.
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 selected equipment. These include, for example:
R Multimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
R Address book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
R Navigation destinations that have been
entered
R Data about using Internet services
This data can be saved locally in the vehicle or
located on a device that you have connected to
the vehicle (e.g. smartphone, USB memory stick or MP3 player). If this data is saved in the vehi-
cle, you can delete it at any time. This data is
sent to third parties only at your request, par-
ticularly when you use online services in accord- ance with the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the equipment in question, these can include:
R Seat and steering wheel position settings
R Suspension and climate control settings
R Custom 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 the 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:
R General vehicle information
R Position 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. Data stored in the vehicle

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
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
(Y page 135).
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 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 (Y page 142).
i The 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.
i Vehicles with ionization of the interior
air with air filter: in addition to ionization,
the vehicle has an air filter with anti-allergenic properties that contribute to improved air fil-
tration.
i It 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. Control panel for dual-zone automatic climate control

matic climate control or 3-zone automatic cli-
mate control.
R You can switch on climate control by using the
0058 and005A or0058 and0056 buttons.
The indicator lamps in the 0058and
005A buttons or the 0058and0056 buttons
light up.
R Vehicles with 3-zone automatic climate
control: in automatic mode, you can also use
the 00F0 button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The MEDIUM
level is recommended.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" function
briefly until the windshield is clear again.
R Only 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.
R Vehicles 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 00D6 button goes out.
R Vehicles 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
deactivated with the ignition switched off.
R If 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 (Y page 145). Operating the climate control sys-
