waste. They must be disposed of at
an appropriate recycling collection
point.

Discharge protection
Battery voltage
When the vehicle battery voltage is
running low, a warning message will
appear in the Driver Information
Centre.
When the vehicle is being driven, the
load reduction function temporarily
deactivates certain functions, e.g. the
heated rear window.
The deactivated functions are
reactivated automatically as soon as
conditions permit.

required due to battery condition, the
power output of the generator must
be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.

The power outlets are deactivated in
the event of low vehicle battery
voltage.Warning label
