open ventilation holes in the vicinity of
the positive terminal. If a ventilation
hole is open in this area, it must be
closed off with a dummy cap, and the ventilation in the vicinity of the
negative terminal must be opened.

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.
Idle boost
If charging of the vehicle battery is
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.

total maximum time of about
40 minutes after ignition is switched
off.
Deactivating power saving mode
Power saving mode is deactivated
automatically when the engine is
restarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutesDiesel fuel system bleeding
If the tank has been run dry, the diesel fuel system must be bled. Switch on
the ignition three times for
