Jump-starting
When 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. Use only
jumper cables with fully-insulated terminal
clamps.
To avoid the risk of potentially fatal
injury, always avoid all contact with
electrical components while the engine is running. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against pos-
sible personal injury.<
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 battery
2.Switch off the engine of the support
vehicle
3.Switch off any electrical systems and
components in both vehicles.
Ensure that no contact exists
between the bodywork on the two
vehicles, otherwise there is a danger of
short circuits.<
Connecting jumper cables
To avoid personal injury from sparks,
always observe this sequence when
connecting jumper cables.<
Your BMW is equipped with an auxiliary
terminal specifically designed for jump-
starting. It is located within the engine
compartment, refer to arrow 1 in the illus-
tration. The symbol + is embossed on the
cover.
1.Remove the cover of the BMW auxiliary
terminal for jump-starting
2.Connect one terminal clamp of the pos-
itive/+ jumper cable to the positive ter-
minal of the battery or an auxiliary termi-

providing starting assistance
3.Connect the second terminal clamp of
the positive/+ jumper cable to the posi-
tive terminal of the battery or to an aux-
iliary terminal for jump-starting of the
vehicle to be started
On your BMW, there is a special nut as
body ground on the suspension strut
dome, refer to arrow2 in the illustration.
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 vehicle providing assistance
5.Connect the second terminal clamp of
the negative/– jumper cable to the neg-
ative 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 support vehicle
and allow it to run for several minutes at
a fast idle
2.Start the engine on the other vehicle in
the usual way.
If the first start attempt is not success-
ful, 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 by
reversing the connection sequence.
If required, have the battery inspected and
recharged at your BMW center.
Never use spray fluids to start the
engine.<
Towing
Using tow fitting
The threaded tow fitting is stored in the
onboard tool kit and must always remain in
the vehicle. It can be screwed in at the front
or rear of the BMW.
To avoid damage to the tow fitting
and the vehicle, observe the follow-
ing: only use the tow fitting that comes with
the vehicle and screw it in as far as it will
go. Only use the tow fitting to tow on roads.
Avoid lateral loading of the tow fitting, e.g.
do not lift the vehicle by the tow fitting.<
Access to screw thread
Press the arrow symbol to push out the
cover.
Being towed
Do not tow the vehicle by the rear
axle; because the steering detent is
not operational, the wheels could turn to an
extreme angle during towing. There is no
power assist with the engine stopped. This
then requires increased effort for braking
and steering.<
Switch on the hazard warning flashers
depending on the local regulations. If the
electrical system fails, mark the vehicle to
be towed, e.g. with a sign or warning trian-
gle in the rear window.
