replacement
Replace the battery as soon as the
range reduces.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Key with foldaway key section
Extend the key and open the unit.
Replace the battery (battery type CR 2032), paying attention to the
installation position. Close the unit
and synchronise.
Key with fixed key section

workshop.
Memorised settings
Whenever the ignition is switched off,
the following settings are
automatically memorised by the
remote control unit:
● lighting
● Infotainment system
● central locking system
● Sport mode settings
● comfort settings
The saved settings are automatically
used the next time the ignition is
switched on with the memorised key
of the remote control unit 3 197.
A precondition is that Personalisation
by Driver is activated in the personal
settings of the Info-Display. This must
be set for each remote control unit
which is used. The status change is
available only after locking and
unlocking the vehicle.
Vehicle personalisation 3 123.
Central locking system Unlocks and locks doors, load
compartment and fuel filler flap.
Instruments and controls123Battery voltageWhen the vehicle battery voltage isrunning low, a warning message will
appear in the Driver Information
Centre.
1. Switch off immediately any electrical consumers which are
not required for a safe ride, e.g.
seat heating, heated rear window or other main consumers.
2. Charge the vehicle battery by driving continuously for a while or
by using a charging device.
The warning message will disappear
after the engine has been started two
times consecutively without a voltage drop.
If the vehicle battery cannot be
recharged, have the cause of the fault
remedied by a workshop.Vehicle personalisation
The vehicle's behaviour can be
personalised by changing the settings
in the Info-Display.
Some of the personal settings for
different drivers can be memorised
individually for each vehicle key.

Battery discharge protection

battery when the ignition is switched
off, some interior lights are switched
off automatically after some time.
Customer information327This data includes, for example:● Vehicle status information (e.g. wheel rotation rate, speed,
movement delay, lateral
acceleration, "seatbelts
fastened" display),
● Ambient conditions (e.g. temperature, rain sensor,
distance sensor).
Most of this data is volatile and is processed only in the vehicle itself,and not beyond the operating time.
Moreover, many control units include
data storage device (amongst others the vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.
The following information, for
example, is stored:
● System component operating states (e.g. fill level, tyre
pressure, battery status),
● State of charge of the high voltage battery, estimated range
(in the case of electric vehicles),● Faults and defects in important system components (e.g. lights,
brakes),
● System reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems),
● Information on events damaging the vehicle.
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, the operating data saved can be read together withthe vehicle identification number andused if necessary. Staff working for
the service net-work (e.g. garages,
manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance
processes, warranty cases and
quality assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which has been read
out documents the technical conditionof the vehicle or individual
components and assists with fault
diagnosis, compliance with warranty
obligations and quality improvement.
This data, in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.
Comfort and infotainment
functions
Comfort settings and custom settings can be stored in the vehicle and
changed at any time.
