Jump starting
When your battery is discharged, you can use
two jumper cables to start the engine of your
BMW with power from the battery in another
vehicle. You can also use the same method to
help start another vehicle. Use only jumper
cables with fully-insulated clamp handles.
To avoid the risk of potentially fatal injury,
always avoid all contact with electrical
components while the engine is running. Care-
fully comply with the following instructions to
avoid personal injury and/or damage to one or
both vehicles.

Preparing
1. Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance in Ah.
This information can be found on the bat-
tery.
2. Switch off the engine of the vehicle provid-
ing assistance.
3. Switch off any electrical systems and com-
ponents in both vehicles.
Ensure that there is no contact between
the bodywork on the two vehicles; other-
wise, there is a danger of short circuits. <
Connecting jumper cables
Connect the jumper cables in the correct
order; failure to do so could generate
sparks and cause injury. <
