Battery
Return used batteries to a
recycling point or your authorized
BMW center. Maintain the battery in
an upright position for transport and
storage. Secure the battery against
falling over in transit.<
Removal and installation
Do not disconnect the battery
when the engine is running. Dis-
connecting the battery cable when the
engine is running will cause a voltage
surge which will damage the vehicle's
onboard electronics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repairs and disposal may only be
performed by specially-trained person-
nel.<
When removing the battery, first dis-
connect the negative terminal, then the
positive terminal. Remove the protec-
tive bar 1 and unscrew the threaded
connection of the battery bracket 2.
When installing the battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery, be sure
that it is mounted properly. Install
and secure the protective bar. If the
battery is not mounted and fastened
properly, it will not be adequately
secured in case of an accident.<
