Using a tow fitting

The screw-in tow fitting must always be carried

in the car. It can be screwed in at the front or

rear of the BMW.

It is stored in the onboard vehicle tool kit under-

neath the floor panel in the cargo area, refer

to page 212.

Use only the towing eyelet supplied with

the vehicle and screw it in firmly until it

Otherwise, the tow fitting and the vehicle could

be damaged.<
