body ground of the vehicle providing assis‐
tance.

ative terminal of the battery, or to the corre‐
sponding engine or body ground of the ve‐
hicle to be started.

If the first starting attempt is not successful,
wait a few minutes before making another

Tow-starting and towing
Tow fitting
The screw-in tow fitting should always be car‐
ried in the vehicle. It can be screwed in at the
front or rear of the BMW. It is located in the tool
kit under the trunk floor.
Tow fitting, information on use
▷ 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, damage to the tow fitting and the ve‐
hicle can occur.◀
