Removing a wheel
! AMG vehicles: during removal and repo-
sitioning of the wheel, the wheel rim can
strike the ceramic-brake disc and damage
it. Therefore, take precautions and get a
second person to assist you. Alternatively,
you can use a second centring pin.
! Do not place wheel bolts in sand or dirt.
The threads of the wheel bolts and wheel
hubs could otherwise be damaged when
the bolts are tightened.
When fitting/removing wheels, and for as
long as the wheels are removed, avoid apply-
ing any external force on the brake disks. This
could impair the level of comfort when brak-
ing.

of damage to the threads, contact a qualified
specialist workshop immediately. Have the
