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.

Concept
A speed limit can be set that when reached will
cause a warning to be issued.
General information
The warning is repeated if the vehicle speed exceeds
the set speed limit again, after it has dropped
below it by 3 mph/5 km/h.
Adjusting
Via iDrive:
1. "CAR".
2. "Settings".
3. "General settin
