Battery Fuses
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
Maintenance The battery is completely maintenance-
free. That means that the original
battery acid will normally last for the
service life of the battery under
moderate climate conditions.
For all questions that regard the
battery, please consult your BMW
center. Since the battery is absolutely
maintenance-free, the following state-
ments are for your information only.<
Do not disconnect the battery
when the engine is running. If you
do so, the ensuing voltage surge will
damage the vehicle's onboard elec-
tronics.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running. Use the
connections provided in the engine
compartment (for correct connections,
refer to "Jump-starting" on page 138.
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 in transit.<
Open the glove compartment and turn
the two white quick-release connec-
tions outward.
Do not attempt to repair a burned
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<

vehicle is also rated at 12 volts. This
information is provided on the top of
the battery casing

your vehicle's electrical system.
Switch off all electrical accessories in
both vehicles
3. Make absolutely certain that there is
no contact between the bodywork of
the two vehicles Ð short circuit hazard
4. Start the engine on the support
vehicle and allow it to run
5. Use one jumper cable (+) to connect
the positive terminal of the battery in
the support vehicle with the auxiliary
positive terminal provided in the
engine compartment of your BMW
specifically for jump-starting. The
cover of the positive terminal
connector is marked with a "+" sign.
Refer to the illustration. Remove by

suitable ground on the vehicle being
started. There is a special nut
provided for this on the BMW

Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
7. Allow the engine on the support
vehicle to run at a fast idle for several
minutes, then start the engine on the
vehicle with the discharged battery in
the usual manner. If the first start
attempt is not successful, wait a few
minutes before another attempt in
order to allow the discharged battery
to recharge

minutes before disconnecting the
jumper cables
9. Then disconnect the jumper cables
in the opposite order.
Have the battery recharged at your
BMW center as required.
