Note: Damage to the ceramic brake disc when changing a wheel
Mercedes-AMG vehicles with ceramic brake discs:during removal and repositioning of the wheel, the wheel rim can strike the ceramic-brake disc and damage it.
Take particular care.
Ask another person for assistance or use a second alignment bolt.
When changing a wheel, avoid applying any force to the brake discs, since this could impair the level of comfort when braking.
Note: Damage to threading from dirt on wheel bolts
Do not place wheel bolts in sand or on a dirty surface.
Unscrew the uppermost wheel bolt completely.
Screw centering pininto the thread instead of the wheel bolt.
