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. You can also use the
same method to help start another
vehicle. Use only jumper cables with
fully insulated grips 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
instructions to avoid personal injury or
damage to one or both vehicles.<
1. Ensure that the battery in the support
vehicle is also rated at 12 volts. This
information is provided on the top of
the battery casing
2 Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories in
both vehicles
3 Make absolutely certain that there is
no contact between the bodywork of
the two vehicles Ð short circuit hazard
4 Start the engine on the support
vehicle and allow it to run
5. Use one jumper cable (+) to connect
the positive terminal of the battery in
the support vehicle with the auxiliary
positive terminal provided in the
engine compartment of your BMW
specifically for jump-starting. The
cover of the auxiliary terminal for use
in jump-starting your BMW is identi-
fied by a "+" symbol, refer to illustra-
tion. Lift off by pulling the tab (arrow) 520de088
6. Next, connect one end of the other
jumper cable (Ð) to either the support
vehicle's negative battery terminal or
a suitable ground on its engine or
bodywork. Connect the other end to
the negative battery terminal or a
suitable ground on the vehicle being
started. There is a special nut
provided for this on the BMW (see
illustration)
Follow the same sequence for
connecting the jumper cables,
otherwise, you run the risk of injury
caused by spark generation at the
battery.<520de133
