Jump-starting
Never use spray starter fluids to start 
the engine.
If the battery is discharged, you can use 
two jumper cables to start your car with 
power from the battery of a second ve-
hicle. Always use jumper cables 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 "Batt. +" (refer to the il-
lustration). Remove by pulling tab. 
The illustration shows the auxiliary 
terminal for jump starting the BMW 
740i/L as an example. For the BMW 
750iL: Refer to "Engine compart-
ment" on page 
380de089
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 ground on the ve-
hicle's engine or bodywork which is 
to be started. Then connect the other 
end of the cable to a ground on your 
vehicle's engine or bodywork (for in-
stance, the nuts on the strut dome. 
Refer to the arrows in the illustration 
above)
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.
