Battery
A highly-explosive gas is
generated when the battery is
charged.
If you happen to get acid in your
eyes, rinse thoroughly for
15 minutes with clear water.
Following that, consult a physician
immediately. If you get acid spray on
your skin or clothing, rinse with plenty
of water. If electrolyte is accidentally
swallowed, consult a physician immedi-
ately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
Maintenance
The battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
Charge condition
You can read the charge condition
of the battery with the "Magic Eye
*"
(a hydrometer):
> Green: Adequate charge
> Black: Not charged adequately.
The battery must be recharged.
Please contact your BMW center
> Yellow: Replace the battery.
The projected service life of the
battery can only be reached if the
battery is fully-charged at all times.
Check the charge condition of the bat-
tery frequently if the vehicle is used pri-
marily for driving short distances.<

Charging the battery
If the battery is charged in the vehicle:
Do not charge the battery with the
engine running.
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury.<
If you plan to store the vehicle for more
than four weeks, disconnect the battery
from the vehicle electrical system by
disconnecting the cable at the negative
terminal and then recharge using a suit-
able charging device.
If you intend to store your car for longer
than 12 weeks: Remove the battery,
charge it and store it in a cool (but frost-
and dust-free) room. Everv three
months and before reinstalling the bat-
tery, have it recharged. If it is not
recharged, it will not be serviceable.
Every time the battery is discharged,
especially over extended periods, its
service life is reduced.
