Battery
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 that will damage the vehicle's on-
board 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 per-
formed by specially-trained person-
nel.<
BMW 750iL: Please contact your autho-
rized BMW center for additional infor-
mation.
BMW 740i/L: When removing the bat-
tery, disconnect the negative terminal
first, then the positive terminal.
Unscrew the battery retaining clamp
(arrow).
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. If the
battery is not mounted properly, it will
not be adequately secured in case of an
accident.<
