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.
Contact with parts conducting
electrical current on a running
engine can be harmful or fatal.<
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
vehicles – 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
engine compartment.
The cover of the positive terminal
connector is marked with a "+" sign.
Refer to the illustration. Remove by
pulling the tab (arrow 1)
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 ve-
hicle that is to be started. This a spe-
cial nut that is provided on the BMW
(arrow 2)
Observe the same sequence for
connecting the jumper cables
when helping other vehicles, otherwise
there is the risk of injury if sparks gener-
ate at the battery.<462de253
6 If the battery on the support vehicle is
weak, start the engine and let it run
7 Start the engine on the vehicle need-
ing the jump-start, and allow it to run
as usual. If the first start attempt is
not successful, wait a few minutes
before another attempt in order to
allow the discharged battery to re-
charge
8 Before disconnecting the jumper ca-
bles from your BMW, turn on the rear
window defroster and set the blower
to the highest speed; allow the en-
gine to run approx. 10 seconds. This
will prevent a voltage surge from the
voltage regulator to the electrical
accessories
9 Then disconnect the jumper cables in
reverse sequence.
Depending on the cause of the fault,
recharge the battery.
