Towing and tow-starting the

vehicle

Using the towing eyelet

The screw-in towing eyelet is stored in the

onboard tool kit; be sure that it remains in the

vehicle at all times. It can be attached at the

front or rear of your BMW.

Observe the following instructions in

order to avoid damaging the towing eye-

let or the vehicle: use only 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 tow-

ing eyelet to lateral loads, e.g. do not lift the

vehicle using the towing eyelet.<

Access to the threaded socket

Press out the cover with a screwdriver inserted

in the recess at the top.

Being towed

Make sure that the ignition key is in posi-

tion 1, because the steering lock could

otherwise engage and the vehicle could no

longer be steered. There is no power assist

while the engine is off. Therefore, you will need

to exert more force to brake and steer the vehi-

cle.<

Turn on the hazard warning flashers, if required

by national regulations. If the electrical system

has failed, clearly identify the vehicle being

towed, e.g. by placing a sign or a warning trian-

gle in the rear window.

Vehicles with manual transmission
