Battery FusesRemoval and installation
Do not disconnect the battery
cables when the engine is running.
If you do so, the ensuing voltage surge
will damage the vehicle's onboard elec-
tronics.
Do not make any modifications in the
wires leading to the positive terminal. If
you do so, the battery safety terminal's
safety function will no longer be guaran-
teed. Repair and disposal must be
performed by trained technicians only.<
When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Unscrew the battery retaining clamp.
When installing the battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery and
cover, be sure that they are
mounted properly. If this is not done,
the battery will not be adequately
secured in case of an accident.<
If an electrical accessory fails, switch it
off and check the fuse.
The fuse box (electrical distribution
center), which contains spare fuses,
relays and plastic tweezers, is located
on the left-hand side of the engine
compartment.
1 Press the retaining flap in and lift off
the cover.
2 Use the plastic tweezers to remove
the fuse for the accessory or equip-
ment that has stopped working.
3 If the fuse is burned through ("blown"),
the metal strip will have melted and
separated. Replace the blown fuse
with a new fuse of the same ampere
rating (color code).36mde795
A listing of the fuses, their respective
ampere ratings and the equipment in
their circuits is provided on the cover of
the fuse box.
When you close the fuse box, be sure
that the cover is seated securely.
Do not attempt to repair a burned
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.<
If a fuse burns through again, have the
source of the fault checked and
corrected by a BMW center.
