Mounting a new wheel
G WARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel
bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
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.
G WARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always pay attention to the instructions and
safety notes in the "Changing a wheel" section
( Y
page 405).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved
for Mercedes-Benz vehicles and the respective
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.
! To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt. X
Clean the wheel and wheel hub contact sur-
faces. X
Slide the wheel to be mounted onto the align-
ment bolt and push it on. X
Tighten the wheel bolts until they are finger-
tight. X
Unscrew the alignment bolt. X
Tighten the last wheel bolt until it is finger-
tight.
Lowering the vehicle
G WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed. X
Place the ratchet wrench onto the hexagon
nut of the jack so that the letters AB are visi-
ble. X
