Battery FusesCharging the battery Charge the battery in the vehicle only
when the engine is not running.
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can cause fire
or personal injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If you intend to store the vehicle for
longer than 12 weeks, remove the
battery, charge it and store it in a cool
and dust-free room where there is no
danger of freezing. During storage,
have the battery recharged every
3 months. Also recharge the battery
before it is reinstalled. If this is not
done, the battery will not be service-
able. Every time the battery is drained,
especially over extended periods, its
service life is reduced.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright
position for transport and storage.
Secure the battery to prevent it from
tilting during transport.<
Storage periods during which
the battery is disconnected are
not taken into consideration by the
Service Interval Display for changing
the brake fluid.
For this reason, be sure that the brake
fluid is changed every two years,
regardless of the information displayed.
Read and comply with the information
on page 138 covering this subject.<
If an electrical accessory should fail,
switch it off and check the fuse. In glove compartment1 Open the glove compartment and
turn the two white quick-release
fasteners outward. Spare fuses and
plastic tweezers are located on the
fuse holder.
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 it with a new fuse
of the same ampere rating (color
code).460de062

Self-diagnostics All of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically; the driver
does not have to perform any extra
operations or adjustments.
The indicator lamps also come on
briefly after the ignition has been turned
on.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, sliding/tilt sunroof, etc.) is
constantly analyzed by current
measurements in their relays.460de177
In the same manner, the electrical
resistance of the airbag ignition genera-
tors and all of the remaining airbag
components is measured at all times.
Any fault in this system would be
detected immediately by a current fluc-
tuation that would necessarily accom-
pany it. The fault would be indicated
immediately by the airbag warning
lamp.
Even after you shut off the engine, the
overall functional status of your vehicle
is monitored. For example, all of the
flaps of the heating and ventilation
system travel to the nearest limit posi-
tion. This action ensures that the
system will be able to provide
defrosting, regardless of other circum-
stances, e. g. if a malfunction in the air
conditioner/climate control system
should occur during the night while the
vehicle is parked.
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors move all air condi-
tioner/automatic climate control flaps to
their limit stops in both directions. The
limit positions and the return travel
paths are checked in this manner in
order to ensure that appropriate adjust-
ments for the operating elements can
be made at any time.You will hear the sounds of the air flaps
as the air conditioning system/auto-
matic climate control carry out their
self-diagnostic functions after the igni-
tion has been turned off. All of the other
self-diagnostics functions operate
silently in the background.
Any possible defects detected during
these self-diagnostics can be read out
by your BMW center and quickly
corrected during the vehicle's next
regularly scheduled maintenance.
