Never use spray starter fluids.
If the battery is discharged, the engine
can be started with the use of two
jumper cables and the battery of another
vehicle. Always use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch the parts conducting
electrical current while the engine
is running. To do so creates the risk of
fatal injury.<
Carefully comply with the following
instructions to avoid personal injury
and damage to one or both vehicles:
1 Be sure that the battery on the
support vehicle is also rated at
12 volts, and that the capacities of
the two batteries (Ah) are roughly
comparable (printed on casing).
2 Leave your battery connected to the
vehicle electrical system.
3 Make sure that there is no contact
between the bodywork of the two
vehicles – this creates a risk of short
circuits.
4 Start by connecting the jumper cable
from the positive terminal of the
support vehicle to the positive
terminal connector located in your
BMW's engine compartment. The
cover of the auxiliary terminal for
jump starting is identified with a
"Batt. +" sign. Refer to the illustra-
tion. Flip the cap out to open.

5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal (–),
or to a suitable ground on its engine
or bodywork. Then connect the other
end of the cable to a ground on the
engine or on the bodywork of the
vehicle that is to be started. There is
a special nut on the strut dome of
your BMW for this (refer to the arrow
in the illustration).
Observe the same sequence for
connecting the jumper cables
when helping other vehicles. If you do
not, there is the risk of injury if sparks
generate at the battery.<
