X
To fit: before fitting, check hub cap :and
the wheel area for soiling and clean if nec-
essary.
X Put hub cap :in position and turn until it is
in the right position.
X Position socket ;on hub cap :.
X Attach wheel wrench =to socket ;and
tighten hub cap :.
The tightening torque must be 25 Nm.
i Note
that the hub cap should be tight-
ened to the specified torque of 25 Nm.
Mercedes-Benz recommends that you have the hub cap fitted at a qualified specialist
workshop. X
Using wheel wrench =, loosen the bolts on
the wheel you wish to change by about one full turn. Do not unscrew the bolts com-
pletely. The jacking points are located just behind the
front wheel arches and just in front of the rear wheel arches (arrows).
X Take the ratchet ring spanner out of the
vehicle tool kit and place it on the hexagon nut of the jack so that the letters

visible. X
Position jack Aat jacking point ?. X
Make sure that the base of the jack is posi-
tioned vertically under the jacking point.
X Turn ratchet ring spanner Buntil jack A
sits completely on jacking point ?and the
base of the jack lies evenly on the ground.
X Turn ratchet ring spanner Buntil the tyre
is raised a maximum of 3 cm from the
ground.
Removing a wheel !
Mercedes AMG vehicles:
when remov-
ing and fitting a wheel, the wheel rim may
strike the ceramic brake disc and damage
it. Therefore, take precautions and have a
second person assist you. Alternatively,
you can use a second 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. Changing a wheel
389Wheels and tyres Z

When fitting/removing wheels, and for as
long as the wheels are removed, avoid apply- ing any external force on the brake discs. This
could impair the level of comfort when brak-
ing. X
Unscrew the uppermost wheel bolt com-
pletely.
X Screw centring pin :into the thread
instead of the wheel bolt.
X Unscrew the remaining wheel bolts fully.
X Remove the wheel.
Fitting 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 ofdamage 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.
Observe the instructions and safety notes on "Changing a wheel" (Y page 386). 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:
when remov-
ing and fitting a wheel, the wheel rim may
strike the ceramic brake disc and damage
it. Therefore, take precautions and have a
second person assist you. Alternatively,
you can use a second centring pin. X
Clean the wheel and wheel hub contact
surfaces.
X Slide the wheel to be mounted onto the
centring pin and push it on.
X Tighten the wheel bolts until they are fin-
ger-tight.
X Unscrew the centring pin.
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. 390
Changing a wheelWheels and tyres

X
Place the ratchet ring spanner onto the
hexagon nut of the jack so that the letters
AB are visible.
X Turn the ratchet ring spanner until the vehi-
cle is once again standing firmly on the
ground.
X Place the jack to one side.
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated ( :
to A). The tightening torque must be
150 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the tyre-
change tool kit in the boot again.
X Check the air pressure of the newly fitted
wheel and adjust accordingly.
Observe the recommended tyre pressure
(Y page 380).
i Vehicles with a tyre pressure control sys-
tem: all fitted wheels must be equipped
with functioning sensors for the tyre pres-
sure control system. Wheel and tyre combinations
General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These are specially adapted to the control
systems, such as ABS or ESP
®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components. This could result in dam- age to the tyres or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tyres,
wheels or accessories other than those tes- ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not fit
used tyres if you have no information about their previous usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases. Wheel and tyre combinations
