Using tow fitting
The threaded tow fitting is stored in the tool
kit mounted on the inside of the luggage
compartment under the floor mat, refer to
page 178, 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 follow-
ing: only use the tow fitting that comes with
the vehicle and screw it in as far as possi-
ble. Only use the tow fitting to tow on the
roadway. Avoid heavy 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 of the cover.

Being towed
Even if there is a failure in the electri-
cal system, make sure that the igni-
tion key is in position 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. The active steering is deacti-
vated; when stopped and in the low speed
range greater steering wheel movements
are required.<
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.
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 dis-
tance of 90 miles/150 km, as otherwise the
automatic transmission may be dam-
aged.<
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 all regulations on
towing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as oth-
erwise 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
impossible to avoid mounting the tow bar
at an offset angle, please observe the fol-
lowing:
>Clearance and maneuvering capability
will be strictly limited in corners
