Removing a wheel
! Mercedes-AMG vehicles with ceramic-
brake disc: during removal and reposition-
ing of the wheel, the wheel rim can strike
the ceramic-brake disc and damage it.
Therefore, you should proceed carefully
and get a second person assist to you.
Alternatively, you can use a second align-
ment bolt.
! Do not place wheel bolts in sand or on a
dirty surface. The bolt and wheel hub
threads could otherwise be damaged when
you screw them in.
When mounting/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.
Unscrew the uppermost wheel bolt com-
X
pletely.
Screw alignment bolt : into the thread
X
instead of the wheel bolt.
Unscrew the remaining wheel bolts fully.

accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
