Vehicle battery
Battery care
The battery is 100 % maintenance-free, the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Battery replacing
Only use vehicle batteries that have been
approved for your vehicle by the manu-
facturer; otherwise, the vehicle could be dam-
aged and systems or functions may not be fully
available.<
After a battery replacement, have the battery
registered on the vehicle by your service center
to ensure that all comfort functions are fully
available.
Charging the battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump-starting
on page235.
Disposal
Have old batteries disposed of by your
BMW center or bring them to a recycling
center. Maintain the battery in an upright posi-
tion for transport and storage. Always secure the battery against tipping over during trans-
port.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings may likewise
have been lost and will have to be programmed:
>Time and date
These values must be updated, refer to
page76.
>Radio
In some cases, stations may have to be
stored again, refer to page147.
>Navigation system
Wait for the system to start, refer to
page141.
>Glass roof
It may happen that the roof can only be
tilted. The system must be initialized.
Please contact your BMW center.
>Seat and mirror memory
*
The positions must be stored again, refer to
page50.
>Inside rearview mirror with digital compass
The system must be calibrated, refer to
page107.
>Active steering
The system automatically initializes itself
briefly during a trip. The system is deacti-
vated during this time, refer to page89.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating; oth-
erwise, this could lead to a circuit overload, ulti-
mately resulting in a fire in the vehicle.<
