& WARNING Risk of accident from losing a
wheel
Oiled, greased or damaged wheel bolt/wheel
nut threads or wheel hub/wheel mounting
bolt threads can cause the wheel bolts/
wheel nuts to come loose.
As a result, you could lose a wheel while driv‐
ing.
Never oil or grease the threads.
#
In the event of damage to the threads,
#
contact a qualified specialist workshop
immediately.
Have the damaged wheel bolts or dam‐
#
aged hub threads replaced.
Do not continue driving.
#
Observe the information on the choice of
#
tyres ( page 534).

For tyres with a specified direction of rotation,
an arrow on the side wall of the tyre indicates
the correct direction of rotation. Observe the
direction of rotation when fitting.
