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.<

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 all electrical accessories in both
vehicles.
There must not be any contact between
the bodies of the two vehicles, as other-
wise there is a danger of shorting.<
Connecting jumper cables
To avoid personal injury from sparks,
observe this sequence when connecting
jumper cables.<
In your BMW, the so-called jump-starting termi-
nal in the engine compartment serves as the
battery positive terminal, also refer to engine
compartment essentials on page175. The
symbol + is embossed on the cover.
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 jump-
starting terminal of the vehicle to be started.
Your BMW has a special nut as body ground or
negative pole.
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.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 for several minutes at
increased speed.
2.Start the engine on the other vehicle in the
usual way.

Towing and tow-starting
Always observe all applicable towing laws
and regulations.<
Never allow passengers to ride in a towed
vehicle for any reason.<
Use tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page180, and
should 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 following: only use
the tow fitting that comes with the vehicle and
screw it in as far as possible. Use the tow fitting
for towing only on roads. Avoid lateral strains on
the tow fitting, e.g. do not the lift vehicle by the
tow fitting.<
Access to screw thread
Rectangular cover in bumper:
Press the arrow symbol of the cover.

Being towed
Make sure that the ignition key is in posi-
tion 1, as otherwise the steering wheel
could lock and it would be impossible to steer
the vehicle. There is no power assist with the
engine stopped. This then requires increased
effort for braking and steering. Active steering is
deactivated and larger steering wheel move-
ments 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.
Vehicles with manual transmission
Gearshift lever in idle position
Vehicles with automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, as otherwise the automatic
transmission may be damaged.<
Vehicles with SMG Sequential manual
transmission
With the ignition switched on, engage selector-
lever position N, then switch off the ignition.
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with the regulations on tow-
ing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be strictly limited during cornering.

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fitting only.
Otherwise to other vehicle parts could
result.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Secure the tow rope to the tow fitting only. Oth-
erwise damage to other vehicle parts could
result.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a load bed.
Do not lift vehicle by tow fitting or body
and chassis parts, as otherwise damage
may result.<
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission.
Jump starting, refer to page186.<
Only tow-start vehicles with a catalytic con-
verter with the engine cold. It is better to jump
start the engine, refer to page186.
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Turn the ignition key to position 2.
3.Shift into 3rd gear, vehicles with SMG, see
below.4.Have the vehicle tow-started with the clutch
pedal completely depressed and slowly
release the clutch. After the engine starts,
immediately depress the clutch pedal com-
pletely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
Vehicles with SMG Sequential manual trans-
