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 accessories 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,
always observe this sequence when con-
necting jumper cables.<
On your BMW the so-called starting-aid termi-
nal in the engine compartment acts as the bat-
tery positive terminal, also refer to the engine
compartment overview on page197. The cover
cap is marked with +.
1.Fold open the cover of the BMW starting-
aid 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
starting-aid 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 pole.
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 start 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.

Giving and receiving assistance

It is located in the toolkit in the luggage com-
partment lid, refer to page203.
Sports Wagon:
It is located in the toolkit behind the left side
panel in the cargo area, refer to page203.
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
Rectangular cover panel in bumper: press on
the arrow symbol on the cover panel.

Being towed
Make sure that the ignition is switched on,
refer to page56, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. If the vehicle
electrical system fails, do not tow-start or tow
the vehicle. The electric steering-wheel lock
cannot be unlocked and the vehicle cannot be
steered. For information on jump starting, refer to page212. There is no power assistance with
the engine stopped. 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.
Manual transmission
Gearshift lever in neutral position.
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, otherwise the automatic
transmission may be damaged.<
SMG Sequential Manual Gearbox
Engage selector lever position N with the igni-
tion switched on.
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably 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 sharply limited during cornering.

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Only attach the tow bar to the tow fittings,
as attachment to other vehicle parts can
lead to damage.<
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.
Only attach tow ropes to the tow fittings, as
attachment to other vehicle parts can lead to
damage.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
With tow truck for 525xi, 530xi
Do not tow the BMW with the front or rear
axle raised individually, otherwise the
wheels may block and the transfer case may be
damaged.<
The BMW may only be transported on a truck
bed.
Tow-starting
If the vehicle electrical system fails, do not
tow-start or tow the vehicle. The electric
steering-wheel lock cannot be unlocked and
the vehicle cannot be steered. Jump starting,
refer to page212.<
Do not tow-start vehicles with an auto-
matic transmission.Only tow-start vehi-
cles with a catalytic converter with the engine
cold. It is better to jump start the engine, refer to
page212.<
