3.8 Preservation of vehicle battery for long periods out of use
If a vehicle is subjected to long periods out of use, the battery will be gradually discharged by electrical consumers (clock, tachograph, cigarette lighter or radio) and thereby permanently damaged.
To avoid this kind of damage, the wiring harness is separated by a connector in the factory and reconnected on vehicle delivery and handover.
Should vehicles be subjected to the same periods out of use at custom body manufacturers, the connector should be separated again.
