charging when the battery is put under high levels of strain. This manifests it-
terminal self by the following.

The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.

Where necessary, large convenience consumers such as seat heaters and
rear window heaters have their power limited or are shut off completely in
the event of an emergency.
CAUTION
Despite such intervention by the vehicle electric system management, the
■
vehicle battery may be drained. For example, when the ignition is switched on
a long time with the engine turned off or the side or parking lights are turned
on during longer parking.
Consumers that are supplied via a 12-V power socket can cause the vehicle
■
battery to discharge when the ignition is switched off.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is
often not aware of it having taken place.
