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
battery frequently if the vehicle is used
primarily for driving short
distances.<
Charging the battery
Charge the battery in the vehicle only
when the engine is switched off.
Charge the battery by using the
connectors in the engine compartment,
refer to jump-starting on page 138.
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 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 your vehicle for
longer than twelve weeks: remove the
battery, charge it and store it in a cool
(but frost- and dust-free) room. Every
three months and before reinstalling the
battery, 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, refer also to
page 117.
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 when trans-
porting.<
