voltage, amperage and be the same size. Suitable vehicle battery types can be

Automatic load deactivation


First read and observe the introductory information and safety warn-
ings on page 168.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This may be noticed from
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 vehi-
■
cle 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 bat-
■
tery to discharge when the ignition is switched off.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is of-
ten not aware of it having taken place.
