Using towing eye
The screw-in towing eye is kept in the car's
toolkit and should always be carried on the car.
It can be screwed into the front or rear end of
the BMW.
Use only the towing eye supplied with the
car, and make sure that it is screwed in
fully and is tight. Only use the towing eye for
towing on roads. Avoid lateral loads of the tow-
ing eye, e.g. do not raise the car at the towing
eye. Otherwise the towing eye and the car could
be damaged.<

action. The steering and brakes will require
extra effort to operate.<
Switch on the hazard warning flashers, depend-

system has failed, the car to be towed must be
made identifiable to following vehicles, for
instance by placing a notice or the warning tri-
angle in the rear window.
