Read and observe and
The vehicle's electrical system automatically prevents the battery from dis-
charging when the battery is being heavily used. This manifests itself by the
following.
▶
The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
▶
Where appropriate large convenience consumers, e.g. seat heaters, rear win-
dow heaters, have their power limited or in case of emergency shut off com-
pletely.

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 which are supplied via a 12 V socket can cause the vehicle battery
■
to discharge when the ignition is switched off.
Note
Driving comfort is not disrupted by any shutting off of consumers. Often the
driver is not aware of it having taken place.
