Observe the applicable laws and regula-
tions for tow-starting and towing vehi-
cles. <
Do not transport any passengers other
than the driver in a vehicle that is being
towed. <
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 with the onboard vehicle tool kit
underneath the floor mat in the cargo area, refer
to page

Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing on paved roads only. Avoid
lateral loading of the tow fitting, e.g. do not lift
the vehicle by the tow fitting. Otherwise, the
tow fitting and the vehicle could be damaged.
