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:
䉯 consider using a proper trickle charger,
following the charger manufacturer’s
instructions, to maintain the battery’s state of
charge; or
䉯 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.
