For all questions that regard the
battery, please consult your BMW
center. The battery is completely main-
tenance-free; the following section is
provided for your information only.<
Do not disconnect the battery
when the engine is running, as the
ensuing voltage surge would damage
the vehicle's onboard electronics.<

the engine.
When your battery is discharged you
can used two jumper cables to start
your car with power from the battery in
a second vehicle. You can also use the
same method to help start another
vehicle. Always use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles.<
1. Ensure that the battery in the
support vehicle is also rated at
12 volts. This information is
provided on the top of the battery
casing
2. Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories
in both vehicles
3. Make absolutely certain that there
is no contact between the body-
work 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 compart-
ment of your BMW specifically for
jump-starting. The cover on this
auxiliary terminal is identified by a
"+" symbol, refer to the illustration.

6. Next, connect one end of the other
jumper cable (Ð) to either the
support vehicle's negative battery
terminal or a suitable ground on its
engine or bodywork. Connect the
other end to the negative battery
terminal or a suitable ground on the
vehicle being started. There is a
special nut on the strut dome of
your BMW; refer to the arrow in the
illustration
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.< 390de146
