Removing a wheel
!
Mercedes AMG vehicles with ceramic-
brake disc: during removal and repositioning
of the wheel, the wheel rim can strike the
ceramic-brake disc and damage it. Therefore,
take precautions and have a second person
assist you. Alternatively, you can use a sec-
ond 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 applying any
external force on the brake discs. This could
impair the level of comfort when braking.

pletely.

Screw centring pin : into the thread instead
of the wheel bolt.
