Removing A Wheel - Mercedes-Benz S-Class Coupe Operator's Manual

Removing a wheel

!
Mercedes-AMG vehicles: during removal
and repositioning of the wheel, the wheel rim
can strike the ceramic-brake disc and dam-
age it. Therefore, you should proceed care-
fully and get a second person assist to you.
Alternatively, you can use a second alignment
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 applying
any external force on the brake disks. This could
impair the level of comfort when braking.

bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of

Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
