Jump starting
When your battery is discharged, you can use
two jumper cables to start your BMW with
power from the battery in a second 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 adhere to the following sequence, both to
prevent damage to one or both vehicles, and to
guard against possible personal injuries.<
Preparation
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 assisting vehi-
cle.
3.Switch off any electrical systems and com-
ponents in both vehicles.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
To avoid personal injury from sparks, fol-
low this sequence when connecting
jumper cables.<
In your BMW, the so-called jump-starting termi-
nal in the engine compartment serves as a pos-
itive terminal for the battery, also refer to engine
compartment overview on page229. The cover
cap is marked with a +.1.Fold open the cover of the BMW jump-
starting terminal. To do so, pull the tab.
2.Attach one end of the jumper cable plus/+
to the positive terminal of the battery or a
jump-starting terminal of the vehicle provid-
ing assistance.
3.Attach the second end of the cable to the
positive terminal of the battery or to a start-
ing-aid terminal of the vehicle to be started.
4.Attach one end of the jumper cable minus/–
to the negative terminal of the battery or to
an engine or body ground of the assisting
vehicle.
Your BMW has a special nut as body ground
or negative terminal.
5.Attach the second end of the cable to the
negative terminal of the battery or to the
engine or body ground of the vehicle to be
started.

Starting engine
1.Start the engine on the assisting vehicle
and allow it to run at idle for several minutes
at slightly increased speed.
2.Start the engine on the other vehicle in the
usual way.
If the first starting attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the connection sequence.
Check the battery and recharge if necessary.
Never use spray fluids to start the
engine.<
Tow-starting and towing
Observe applicable laws and regulations
for tow-starting and towing.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using tow fitting
The screw-on tow-fitting must always be car-
ried in the vehicle. It can be screwed in at the
front or rear of the BMW.
Sedan:
It is located in the toolkit in the luggage com-
partment lid, refer to page234.
Sports Wagon:
It is located in the toolkit behind the left side
panel in the cargo bay, refer to page234.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing only on roads. Avoid lateral
loading of the tow fitting, e.g. do not lift the vehi-
cle by the tow fitting. Otherwise damage to the
tow fitting and the vehicle can occur.<
Access to screw thread
Press the arrow symbol on the cover in the
bumper.

Being towed
Make sure that the ignition is switched on,
refer to page60, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. Do not tow the
vehicle with the rear axle raised, as otherwise
the steering can turn to the left or right. When
the engine is stopped, there is no power assist.
This then requires increased effort for braking
and steering. Active steering is deactivated and
larger steering wheel movements are
required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
