BMW 3: Designation and identification
Designation of electrical machines
The electrical machine designation is used in the technical documentation for clear identification of the electrical machine. However, the identification of the electrical machine is relevant for Service.
Identification of the electrical machine
The electrical machines have an identification to ensure clear identification and classification. This identification is also necessary for approval by government authorities. The identification of the electrical machines is equivalent to the identification of the combustion engines. The serial number of the electrical machine can be found under the electrical machine identification on the electrical machine. This consecutive number, in conjunction with the identification, permits clear identification of each individual electrical machine.
The identification of the electrical machine in a G20 PHEV is as follows: GC1P25A.

System limits
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not be
detected.
Deceleration
The system does not decelerate in the following
situations:
For pedestrians or similarly slow-moving road
users.
For red tr
