3.4 Split or separated high-voltage battery
The voltage within the high-voltage battery cannot in principle be switched off. The high-voltage battery is, however,
designed to be intrinsically safe on the inside. This includes, for example, an adequate touching protection. All high-
voltage cables can be plugged in and are highlighted in orange. In case of a damaged high-voltage battery, a damaged
touching protection needs to be assumed.
In this very improbable case, electrical and thermal danger by the high-voltage battery need to be assumed. Adequate
personal protective equipment is required.
The elements of the high-voltage battery should be lifted from the ground with insulating material (for example wood). If
any elements are held together only by individual lines, disconnecting and/or cutting through the lines may be
recommended. Disconnect and/or cut through lines one by one in order to provide dangerous short circuits.
The elements can be lifted onto a truck with insulating facing on the loading platform and then be covered with an
insulating cover. Install an adequate high-voltage sign with a corresponding note.
First recovery of the vehicle with damaged high-voltage battery is secured by law.

4 Towing
When towing away a severely damaged vehicle, the following points need to be kept in mind:
.
The vehicle must not be pulled or towed. Transportation is possible exclusively on a truck. Any other variants of towing
away a vehicle are forbidden. Pulling the vehicle out of the danger area is possible. Securing the vehicle via its wheels is
After recovery out of water:
- Observe vehicle thoroughly.
- Store vehicle outdoors with sufficient clearance to combustible material!
- Provide clear access for fire brigade.
- Observe notes on towing away inside the rescue manual, the emergency services data sheet and/or the
Owner's Handbook.
- The vehicle may only be towed away be trained personnel.
- The high-voltage system is to be switched off before transporting (de-energised).
- Insulating tensioning straps and lifting gear are to be used.
- Not specifically trained persons are to be kept away.
- If the vehicle does not stand on its own wheels, adequate insulation material is to be used. The vehicle body
may not have any metallic contact to the loading platform.
- The elements of the high-voltage battery can be lifted onto a truck with insulating facing on the loading
platform and then be covered with an insulating cover.
- The vehicle is to be secured sufficiently in order to avoid further damage to the high-voltage battery due to
movement.
- If the vehicle can be repaired, it should be transported to the nearest BMW authorised workshop if possible.
