26Keys, doors and windowsPassive lockingOn vehicles with electronic key
system, this feature locks the vehicle
automatically after several seconds if
an electronic key has been
recognised previously inside the
vehicle, all doors have then been
closed and the electronic key does
not remain within the vehicle.
If the electronic key remains in the
vehicle or the vehicle is not off,
passive locking will not be permitted.
If there have been two or more
electronic keys in the vehicle and the
vehicle was on once, the feature locks the vehicle if just one electronic key is
taken out of the vehicle.
To prevent passive locking of the
vehicle e.g. when passengers remain in the vehicle, the system must be
disabled.
To disable the system, press the
central locking button ( for a few
seconds while one door is open. The function remains disabled until the
central locking button ) is pressed or

Odometer
The total recorded distance is

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 as estimated from
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 upon changes in
climate control energy consumption.
A trend bar on the far left indicates
how recent vehicle conditions and
climate settings are affecting the
learned 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.
