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 an-
other vehicle. Always use jumper ca-
bles with fully insulated handles on the
terminal clamps.
Do not touch high-voltage wiring
and cables on a running engine.
There is a risk of fatal injury if you do
this.<
Carefully comply with the following in-
structions to avoid personal injury and
damage to one or both vehicles:
1 Ensure that the battery on the sup-
port 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
car electrical system.
3 Make sure that there is no contact
between the bodywork of the two ve-
hicles – short circuit risk.
4 Start by connecting the jumper cable
from the positive terminal of the sup-
port vehicle to the positive terminal
connector located in your BMW's en-
gine compartment. The cover of the
auxiliary terminal for jump starting is
marked with a "+" sign (refer to the
illustration). Remove the cover by
pulling tab. The illustration shows the
external start support point of the
BMW 528i. For the BMW 540i, refer
to "Engine compartment" on
page 146.

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 body of the vehicle which is
to be started. There is a special nut
on the strut dome of your BMW; refer
to the arrow in the illustration.
Follow the same sequence for
connecting the jumper cables if
you assist in jump-starting another ve-
hicle. If you do not, there is a risk of in-
jury caused by spark generation at the
battery.<
