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. <
In your BMW, the so-called jump starting termi-
nal in the engine compartment functions as the
positive battery terminal, also refer to engine
compartment overview on page

symbol + is embossed on the cover.
1. Open the cover of the BMW jump starting
terminal, refer to arrow

2. Connect one terminal clamp of the posi-
tive/+ jumper cable to the positive terminal
of the battery or to a jump starting terminal
of the vehicle providing starting assistance.
3. Connect the second terminal clamp of the
positive/+ jumper cable to the positive ter-
minal of the battery or to a jump starting ter-
minal of the vehicle to be started.
4. Connect one terminal clamp of the nega-
tive/– jumper cable to the negative terminal
of the battery or to an engine or body
ground of the vehicle providing assistance.
Your BMW has a special nut that serves as
the body ground or negative terminal, refer

negative/– jumper cable to the negative ter-
minal of the battery or to the engine or body
