	Checking
1	Check condition of battery		AR54.10-P-1129SY
	Removing
2	Remove cover of engine compartment prefuse box (F32/3)
	Charging
3	Connect charger positive terminal (1) to charging terminal point (4) of engine compartment prefuse box (F32/3)
4	Connect charger ground terminal (2) to ground terminal point (3) on wheel well and switch on charger	Do not connect with incorrect polarity, risk of short-circuit. Use a charger with at least 30 A charging current and 13.5 V charging voltage, otherwise the on-board electrical system battery could be partially discharged.
5	Charge on-board electrical system battery (G1)	Discharged AGM batteries which have a voltage below 7 V may not be "recognized" depending on the type of charger. A second charged battery (with a rated voltage of 12 V) must therefore be connected in parallel to the AGM battery before charging. Normal charging: Charging current max. 10 % of battery capacity: e.g. max. 10 A charging current for a 100 Ah battery. Rapid charging: charging current max. 50 % of battery capacity for 30 min: e.g. max. 50 A charging current for a 100 Ah battery.
6	Disconnect battery charger	Always switch off charger beforehand in order to prevent arcing.
