If a normal or quick charger is used to charge the battery, the battery must be disconnected from the vehicle electrical system and removed. This prevents damage to paintwork and upholstery.
IMPORTANT:
In order to prevent malfunctions on the intelligent battery sensor (IBS), the charging terminals in the engine compartment must be used without fail on vehicles with IBS (from E60). On other vehicles, we recommend the charging terminals in the engine compartment are used.
