BatteryMaintenanceThe battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions.
Please consult your BMW center
whenever you have any questions
concerning the battery. The battery is
completely maintenance-free; the fol-
lowing section is provided for your
information only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems. cle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment. For
terminal locations, refer to Jump-start-
ing on page 147.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery against tilting during trans-
port.<
FusesYou will find the fuses and information
on their respective allocation in the
glove compartment behind a panel with
two snap clips.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<
