properly, the central locking system
will not work.
Passive locking
Automatic locking 3 28.
Confirmation
Operation of central locking system is confirmed by the hazard warning
flashers. A precondition is that the
setting is activated in the vehicle
personalisation 3 123.
Fault
If the central locking cannot be
operated or the engine cannot be
started, the cause may be one of the
following:
● Fault in electronic key.
● Electronic key is out of reception range.
● The battery voltage is too low.● Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
To rectify the cause of the fault,
change the position of the electronic
key.
Manual unlocking 3 26.
Memorised settings
Whenever the ignition is switched off, some of the following settings are
automatically memorised by the
currently used remote control unit or
the electronic key:
● automatic climate control
● lighting
● Infotainment system
● central locking system
● FlexRide interactive driving system
● comfort settingsThe saved settings are automatically
used the next time the ignition is
switched on with the memorised
electronic key 3 23.
A precondition is that Personalisation
by Driver is activated in the personal
settings of the Info Display. This must
be set for each electronic key which is
used. The status change is available
only after locking and unlocking the
vehicle.
The assigned memory position of the power seat is automatically recalled
when switching on ignition and Auto
Memory Recall is activated in the Info
Display for the memorised electronic
key.

304Customer informationVehicle data recording
and privacy
Event data recorders
Electronic control units are installed in
your vehicle. Control units process
data which is received by vehicle
sensors, for example, or which they
generate themselves or exchange
amongst themselves. Some control
units are necessary for the safe
functioning of your vehicle, others
assist you while you drive (driver
assistance systems), while others
provide comfort or infotainment
functions.
The following contains general
information about data processing in
the vehicle. You will find additional
information as to which specific data
is uploaded, stored and passed on to third parties and for what purpose in
your vehicle under the key word Data Protection closely linked to the
references for the affected functional
characteristics in the relevant owner's manual or in the general terms of
sale. These are also available online.Operating data in the vehicle
Control units process data for
operation of the vehicle.
This data includes, e.g.: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate,
"seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient, not
stored for longer than an operational
cycle, and only processed on board
the vehicle itself. Control units often
include data storage (including the vehicle key). This is used to allowinformation to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.Depending on technical equipment
level, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used when necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.
