Jump-startingWhen your battery is discharged you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Only use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles. support vehicle has 12 volts and
approximately the same capacity –
measured in Ah. This information is
provided on the battery
2. Stop the engine of the support vehi-
cle
3. Switch off all electrical components
in both vehicles.
Make absolutely certain that there
is no contact between the body-
work of the two vehicles, otherwise
there is a short circuit hazard.<
Connecting the jumper cables
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
The auxiliary jump-starting terminal
located in your BMW's engine compart-
ment acts as the positive battery termi-
nal. Refer to the engine compartment
overview on page, 136. The cover of
this auxiliary terminal is marked with
a +.
1. Open the cover of the BMW auxiliary
jump-starting terminal. Do so by pull-
ing the tab – see arrow 1
2. Connect one terminal clamp of the
plus/+ jumper cable to the positive
terminal of the battery or to an auxil-
iary jump-starting terminal of the
support vehicle
3. Connect the second terminal clamp
of the plus/+ jumper cable to the
positive terminal of the battery or to
an auxiliary jump-starting terminal of
the vehicle to be started
4. Your BMW is equipped with a special
nut – see arrow 2 – to serve as the
ground or negatvie terminal.
Attach a terminal clamp of the
minus/– jumper cable to the negative
terminal of the support vehicle's bat-
tery or to a suitable ground on its
engine or bodywork
5. Attach the second terminal clamp of
the minus/– jumper cable to the neg-
ative terminal of the battery or to a
suitable ground on the engine or
bodywork of the vehicle to be
started.Starting the engine1. Start the engine of the support vehi-
cle and let it run for several minutes
at a slightly elevated engine idle

as usual.
If the first start attempt is not suc-
cessful, wait a few minutes before
another attempt in order to allow the
discharged battery to recharge
3. Allow the engines to run for several
minutes
4. Disconnect the jumper cables in
reverse sequence.
Depending on the cause of the fault,
have the battery checked and
recharged by your BMW center.
Do not use spray starter fluids to
start the engine.<
