Towing
Using tow fitting
The threaded tow fitting is stored in the
onboard tool kit and must 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 it will
go. Only use the tow fitting to tow on roads.
Avoid 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 to push out the
cover.
Being towed
Do not tow the vehicle by the rear
axle; because the steering detent is
not operational, the wheels could turn to an
extreme angle during towing. There is no
power assist with the engine stopped. This
then requires increased effort for braking
and steering.
<
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.
