deteriorates strictly on a mileage basis and

pollution.
Battery Care
If your car is driven only for short distances of
less than 10 miles over a prolonged period of
time, without an occasional drive at highway
speeds, the engine’s charging system will not
maintain the battery. Insufficient use of the
vehicle could result in short term starting
problems and in the long term could damage
the battery.
In case the car is not operated for several
weeks it is advisable to:
a) slide battery switch to “Off”position. Refer
to “Battery Switch”in vehicle owner’s
manual.
b) consider using a proper trickle charger,
following the charger manufacturer’s
instructions, to maintain the battery’s state
of charge; or
c) consult your BMW center regarding battery
removal. Once removed, the battery must
be charged and stored in a cool, dry place
where it can be protected from freezing. If
the battery will be stored for over 3
months, it must be recharged every 3
months, or else it will become damaged
and useless.
Please consult with your BMW center for
further guidance and information.
