BMW 3 Owners & Service Manuals

BMW 3: Labels

Three signs are attached to the housing of the high-voltage battery unit: 1 type plate and 2 warning stickers. The type plate provides logistical information (e.g. part number) and the key technical data (e.g. nominal voltage). The warning stickers point to the lithium-ion technology on the one hand, and on the other to the high electrical voltage that exists in the high-voltage battery unit. They thus raise awareness of the potential dangers involved.

The type plate is now also legible with the high-voltage battery installed.
