Automatic consumer disconnection
The intelligent vehicle electrical system automatically implements a range of
measures to prevent the battery from discharging when high demands are
made on it:
the idling speed is increased so that the alternator provides more elec-
tricity.
where necessary, the power of the most powerful consumers is reduced
or even completely disconnected.

Booklet "Maintenance
On starting the engine, the power supply from the 12-volt sockets and the
cigarette lighter may be interrupted for a short time.
The on-board management programme cannot always prevent the battery
from running flat. For example, if the ignition is left on for a long period with
the engine off or if the side lights or parking lights are left on while the vehicle
is stationary.
Why does the battery run flat?
When stationary for a long time without starting the engine, particularly if
the ignition is switched on.
Use of electrical consumers with the engine switched off.
If the auxiliary heater is running
WARNING
Incorrectly securing the battery or using the wrong battery can cause
short-circuits, fire and serious injuries.
Always use only maintenance free batteries that do not run flat alone
and whose properties, specifications and size correspond to the standard
battery. The specifications are indicated on the battery case.
WARNING
A highly explosive mixture of gases is released when the battery is under
charge.
The batteries should be charged in a well-ventilated room only.
Never charge a frozen or recently thawed battery. A flat battery can
freeze at temperatures around 0°C (+32°F).
Always replace a battery which has frozen.
Battery cables not correctly connected may cause a short circuit.
Reconnect first the positive cable and then the negative cable.
