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.
It is imperative to observe the instructions and
safety notes on "Changing a wheel"
(Y page 342).
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. :
Wheel bolts for the collapsible emergency
spare wheel (Mercedes-AMG vehicles)
; Wheel bolts for all wheels supplied by the
factory
Mercedes-AMG vehicles: always use wheel
bolts :to fit the emergency spare wheel.
The wheel bolts for emergency spare wheel :
can be found in the emergency spare wheel bag
in the luggage compartment. X
Clean the wheel and wheel hub contact sur-
faces.
X Place the new wheel on the wheel hub and
push it on.
X Tighten the wheel bolts until they are 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 ring spanner onto the hex-
agon nut of the jack so that the letters ABare
visible.
X Turn the ratchet ring spanner until the vehicle
is once again standing firmly on the ground.
X Place the jack to one side. 346
Changing a wheelWheels and tyres

X
Tighten the wheel bolts evenly in a crosswise
pattern in the sequence indicated (: toA).
The tightening torque must be 130 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the vehicle tools
in the vehicle again.
X Mercedes-AMG vehicles and vehicles
with AMG Line:
use the cover of the outer sill.
X Check the tyre pressure of the newly fitted
wheel and adjust if necessary.
Observe the recommended tyre pressures
(Y page 337).
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning sys-
tem or the tyre pressure monitor cannot func-
tion reliably. Restart the tyre pressure loss warn- ing system or tyre pressure monitor only once
the defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: all fitted
wheels must be equipped with functioning sen-
sors. Wheel and tyre combinations
General notes
You can ask for information regarding permitted
wheel/tyre combinations at a Mercedes-Benz
Service Centre.
You should regularly check the pressure of all
your tyres, including the emergency spare
wheel, particularly prior to long trips, and cor-
rect the pressure as necessary (Y page 337).
The value on the wheel is valid.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle.
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 spe-
cifically approved by Mercedes-Benz. Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from
any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected 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 comfort and suspension comfort are reduced and therisk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommended tyre pressures for various
operating conditions can be found on the tyre
pressure table on the fuel filler flap. Further
information on tyre pressure (Y page 337).
Check tyre pressures regularly and only when
the tyres are cold.
Notes on the vehicle equipment – always fit the
vehicle:
R with tyres of the same size across an axle
(left/right)
R with the same type of tyre (summer tyres,
MOExtended tyres, winter tyres)
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics)" section
(Y page 318).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that Wheel and tyre combinations
