Automatic switch-off for electrical consumers
The intelligent vehicle electrical system automati-cally implements a range of measures to prevent the battery from discharging under high loads:
• The idling speed is increased so that the alter-nator provides more electricity.
• The performance of large electrical consumers may be reduced or they may be switched off com-pletely.
• The supply of electricity to the 12-volt sockets and the cigarette lighter is interrupted temporarily while the engine is being started.
The vehicle electrical system cannot always pre-vent the vehicle battery from discharging. For ex-ample, if the ignition is left on for an extended peri-od of time with the engine off, or if the parking light is left on when the vehicle is parked for an exten-ded period.
What can cause the vehicle battery to discharge?
• Long periods at a standstill in which the engine is not running, especially if the ignition is switched on.
• The use of electrical consumers when the en-gine is switched off.
• When the supplementary heater is in operation =>page 332.
