Charging the battery
Charge the battery in the vehicle only
when the engine is not running.
Before doing any work on the
electrical system, be sure to dis-
connect the cable from the battery's
negative terminal. Failure to do so could
result in short-circuits, a fire or personal
injury.
<
If the vehicle is to be parked longer than
four weeks, disconnect the battery from
the vehicle's electrical system by dis-
connecting the negative terminal cable
and then recharge using a suitable
charging device.
If you intend to store your car 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 bat-
tery, have it recharged. If it is not re-
charged, it will not be serviceable. Every
time the battery is discharged, espe-
cially over extended periods, its service
life is reduced.
Avoid environmental pollution
when disposing of old batteries.
<
Return used batteries to a recy-
cling point or your authorized
BMW center. Maintain the battery in an
upright position for transport and stor-
age. Secure the battery against tilting in
transit.
