should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
Only use the tow fitting that comes with
the vehicle and screw it in as far as possi-
ble. Use the tow fitting for towing only on roads.
Avoid lateral loading of the tow fitting, e.g. do
not lift the vehicle by the tow fitting. Otherwise
damage to the tow fitting and the vehicle can
occur.<
Access to screw thread
Front: press the arrow symbol on the cover in
the bumper.
Rear: press the arrow symbol on the cover while
prying out the cover upward by hand.
Being towed
Make sure that the ignition is switched on,
refer to page55, 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.<
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.
Sequential Manual Transmission with
Drivelogic
Make sure that selector lever position N is
engaged with the ignition switched on, as
otherwise the engine can be damaged during
towing.<
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.

Giving and receiving assistance
216 Only attach tow ropes to the tow fittings, as
attachment to other vehicle parts can lead to
damage.<
With tow truck
Do not tow the vehicle with only the front
or rear axle raised, as otherwise the
engine may be damaged or the steering can
turn to the left or right.<
Have the vehicle transported on a flatbed sur-
face only.
