Tow-starting, towing away
Using the towing eyelet
The screw-in tow fitting must always be carried
in the car. It can be attached at the front or rear
of your BMW.
It is located in the onboard tool kit, refer to
page
98 .
Only use the towing eyelet supplied with
the vehicle, and screw it in firmly until it
stops. Use the towing eyelet for towing on
paved roads only. Avoid subjecting the towing
eyelet to lateral loads, e.g. do not lift the vehicle
using the towing eyelet. Otherwise the tow fit-
ting and the vehicle could be damaged.
