Starting the engine

let it run for several minutes at a slightly ele-
vated engine idle speed

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.
