Electronic key synchronisation
The electronic key synchronises itself automatically during every starting
procedure.
Fault
If the central locking cannot be
operated or the propulsion system
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 20.Memorised settings
Whenever the vehicle is switched off, the following settings are
automatically memorised by the
electronic key:
● automatic climate control
● lighting
● Infotainment system
● central locking system
● comfort settings
The saved settings are automatically
used the next time the vehicle is
switched on with the memorised
electronic key 3 19.
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.

Central locking system Unlocks and locks doors and load
compartment.A pull on an interior door handle
unlocks the respective door. Pulling
the handle once more opens the door.
Note
In the event of an accident in which
airbags or belt pretensioners are
deployed, the vehicle is
automatically unlocked.
Note
A short time after unlocking with the
remote control the doors are locked
automatically if no door has been
opened. A precondition is that the
setting is activated in the vehicle

90Instruments and controlsSome important messages may
appear additionally in the Info
Display. Some messages only pop-
up for a few seconds.
Warning chimes If several warnings appear at the
same time, only one warning chime will sound.
When starting the propulsion
system or whilst driving
The warning chime regarding not
fastened seat belts has priority over
any other warning chime.
● If seat belt is not fastened.
● If a door or the tailgate is not fully
closed when starting off.
● If a certain speed is exceeded with parking brake applied.
● If approaching a vehicle ahead too rapidly.
● If a programmed speed or speed
limit is exceeded.
● If a warning message appears in the Driver Information Centre.● If the electronic key is not in thepassenger compartment.
● If the parking assist detects an object.
● If an unintended lane change occurs.
● If safety function of the power tailgate detects obstacles in the
moving area.
When the vehicle is parked and /
or the driver's door is opened
● With exterior lights on.
Battery voltage
When the voltage of the 12 V vehicle
battery is running low, a warning
message will appear in the Driver
Information Centre.
1. Switch off any electrical consumers which are not requiredfor a safe drive, e.g. seat heating,
heated rear window or other main
consumers.
2. Charge the 12 V vehicle battery by
driving continuously for a while or
by using a charging device.The warning message will disappear
after the vehicle has been started
twice without a voltage drop.
If the 12 V vehicle battery cannot be
recharged, have the cause of the fault remedied by a workshop.
Lighting105Lighting features
Entry lighting Low beam and the interior lights turn
on briefly by pressing ( on the
electronic key. The lights turn off
immediately when POWERm is
pressed or automatically after a brief period.
Exit lighting The low beam and the reversing light
come on by doing the following:
1. Switch off the vehicle.
2. Open the driver's door.
3. Pull the stalk briefly and release.
Some interior lights come on when
the vehicle is switched off. The
exterior and the interior lights remain
on after the door is closed for a brief
period and then turn off.
Activation, deactivation and duration
of this function can be changed in the
Info Display.
Vehicle personalisation 3 91.Battery discharge protection
Vehicle battery state of charge
function
The vehicle battery saver feature is
designed to protect the 12 V vehicle
battery. If any interior light is left on and the vehicle is switched off, thevehicle battery discharge protection
system automatically turns the lights
off after approx. 10 minutes.
If the exterior lights are left on, they
turn off when the vehicle is switched
off. If the sidelights are switched on
when the vehicle is switched off, the
sidelights remain on until they are
manually switched off.
260Customer informationThis 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 with the 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.
