Do not use spray starter fluids to start
the engine.
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
current while the engine is
running. Failure to comply with this
creates a 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's 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 marked with a "+"
sign (refer to the illustration). To
remove the cover, tip up the cap
(arrow). The illustration shows the
auxiliary terminal for jump starting on
the BMW X5 4.4i. For the BMW
X5 3.0i: refer to "Engine compart-
ment" on page 152.530us126
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 for this on the left side
panel of your BMW. Refer to the
arrow in the illustration.
Follow 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.< 530us127
