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 ignition is switched off, some functions of the following
settings may be automatically
memorised by the remote control unit
or 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.

Indicates vehicle speed.
Odometer
The total recorded distance is
displayed in km.
Battery gauge
This displays the high voltage battery state of charge. The value in the
centre is an estimate of how far the
vehicle can be driven on the
remaining charge based on driving
habits and conditions learned over several days.
The maximum value is shown above
the display and the minimum value
below the display. The values
indicate the longest and shortest
possible range as estimated from
current vehicle conditions and climate
settings.
The mileage estimate and maximum
and minimum numbers are affected
by climate control system usage.
Estimated range may increase or
decrease based on changes in
climate control energy consumption.
A trend bar on the far left indicates
how recent driving habits, vehicle
conditions and climate settings are
affecting the range prediction.
When the high voltage battery state of charge is very low the estimated
range value in the centre will change
to Low . Maximum and minimum
ranges will no longer be displayed.
Additional alerts may display and a
sound may also be heard at low state
of charge.

Energy details
The Energy details screen displays
how energy is being used since the
last time the high voltage battery was
fully charged. It includes Driving and
accessories , Climate settings and
Battery conditioning . The circle graph
displays these percentages. Energy
used and Distance travelled are also
displayed on the screen.
Range Impacts Since Last Full
Charge
This screen provides an estimate of
the factors that influence energy
usage since the last full charge of the
high voltage battery. A positive
number is desired to reach the
vehicle’s electric economy rating.
● Technique includes speed,
acceleration, and braking.
● Terrain includes road conditions,
such as hills, rain, and snow and
may be affected by wind and tyre pressure.
88Instruments and controls●Climate settings includes how the
heating and air conditioning are
used. Using fan only settings will
help reduce your climate setting
losses.
● Outside temperature includes the
effect that hot or cold air has on
vehicle aerodynamics.
The individual vehicle range impacts
provide an understanding of how electric economy are different from
day-to-day, even when travelling the
same route.
All values are reset after a complete
charge and may not be stable until
approximately 16 km have been
driven.Efficiency History
The Efficiency History graph shows
the average economy over the last
50 km.
The present bar provides the average economy for the current 5 km.
