tery in an upright position for transport and stor-
age. Secure the battery against tilting when
transporting.<

of each of the items regularly, and replace any
with passed dates. These items can be pur-
chased in any drugstore or pharmacy.
Always observe all legal regulations requiring a
first-aid kit to be carried in the vehicle.<
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. Always use jumper cables with
fully insulated handles on the terminal clamps.
Do not touch components carrying cur-
rent on a running engine. Contact with
these components can cause fatal injury. Care-fully observe the following instructions to avoid
personal injury and/or damage to one or both
vehicles.<
Preparations
1.Check whether the battery of the support
vehicle has 12 volts and approximately the
same capacity – measured in Ah. This infor-
mation is provided on the battery
2.Stop the engine of the support vehicle
3.Switch off all electrical accessories in both
vehicles.
Make absolutely certain that there is no
contact between the bodywork of the two
vehicles: short circuit hazard.<
Connecting 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 compartment acts as the
positive battery terminal. Refer to the engine
compartment overview on page85. The cover
is marked with a+.
1.Open the cover of the BMW auxiliary jump-
starting terminal. Do so by pulling the tab
2.With the + jumper cable, connect the posi-
tive terminal of the drained battery and the
positive terminal of the support battery.
To do this:
Connect one terminal clamp to the positive
terminal of the battery or to an auxiliary
jump-starting terminal of the support vehi-
cle.
Connect the second terminal clamp to the

Giving and receiving assistance
98 positive terminal of the battery or to an aux-
iliary jump-starting terminal of the vehicle to
be jump-started.
Your BMW is equipped with a special nut,
refer also to the engine compartment over-
view on page85
3.With the– jumper cable, connect the nega-
tive terminals of both vehicles.
To do this:
Attach one cable clamp to the negative bat-
tery terminal or to a suitable ground on the
engine or body work of the support vehicle.
Attach the second cable clamp to the nega-
tive battery terminal or to a suitable ground
on the engine or body work of the vehicle to
be jump-started.
Starting the engine
1.Start the engine of the support vehicle and
let it run for several minutes at a slightly ele-
vated engine idle speed
2.Start the engine of the other vehicle as
usual.
If the first start attempt is not successful,
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.Then disconnect the jumper cables in
reverse sequence
5.Depending on the cause of the fault, have
the battery checked and recharged.
Never use spray starter fluids to start the
engine.<
Towing and tow-starting the
vehicle
Using the towing eyelet
The screw-in towing eyelet is stored in the
onboard tool kit; be sure that it remains in the
vehicle at all times. It can be attached at the
front or rear of your BMW.
Observe the following instructions in
order to avoid damaging the towing eye-
let or the vehicle: use only the towing eyelet
supplied with the vehicle, and screw it in firmly
until it stops. Use the towing eyelet for towing
on paved roads only. Avoid subjecting the tow-
ing eyelet to lateral loads, e.g. do not lift the
vehicle using the towing eyelet.<
Access to the threaded socket
Press out the cover with a screwdriver inserted
in the recess at the top.
Being towed
Make sure that the ignition key is in posi-
tion 1, because the steering lock could
otherwise engage and the vehicle could no
longer be steered. There is no power assist
while the engine is off. Therefore, you will need
to exert more force to brake and steer the vehi-
cle.<
Turn on the hazard warning flashers, if required
by national regulations. If the electrical system
has failed, clearly identify the vehicle being
towed, e.g. by placing a sign or a warning trian-
gle in the rear window.
