may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging front and rear wheels of differing
dimensions can render the general operating
permit invalid.
Observe the instructions and safety notes in the "Fitting a wheel" section (Y page 268).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders and the rear
tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and reac-
tivate the tyre pressure monitor if necessary. Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua- planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably dark
place if they are not being used. Protect the
tyres against oil, grease, petrol and diesel. Fitting a wheel

R centring pin
Securing the vehicle against rolling
away 268
Changing a wheelWheels and tyres

If your vehicle is equipped with a wheel chock, it
can be found in the tyre-change tool kit
(Y page 246).
The folding wheel chock is an additional secur-
ing measure to safeguard the vehicle from roll-
ing away, for example when changing a wheel.
X Fold both plates upwards :.
X Fold out lower plate ;.
X Insert the lugs on the lower plate fully into the
openings in base plate =.X
Place chocks or other suitable items under
the front and rear of the wheel that is diago-
nally opposite the wheel you wish to change.
Raising the vehicle G
WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the vehi- cle:
R to raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If the jack is used incor-
rectly, it could tip over while the vehicle is
raised.
R the jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not permissible to use it to per- form maintenance work under the vehicle. R
avoid changing the wheel on uphill and down-
hill slopes.
R before raising the vehicle, safeguard it from
rolling away by applying the parking brake and
positioning wheel chocks. Do not release theparking brake while the vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
flat load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
R do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
R make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R never place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised.
R do not open or close a door or the tailgate
while the vehicle is raised.
R make sure that no persons are present in the
vehicle when the vehicle is raised.

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.
! Vehicles with a collapsible emergency
spare wheel: Inflate the collapsible emer-
gency spare wheel using the tyre inflation
compressor before lowering the vehicle. The
rim could otherwise be damaged.
X Turn the crank of the jack anti-clockwise until
the vehicle is once again standing firmly on

X Place the jack to one side. X
Tighten the wheel bolts evenly in a crosswise
pattern in the sequence indicated (: toA).
The specified tightening torque is 180 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 load compartment again.
X Check the air pressure of the newly fitted
wheel and adjust accordingly.
Observe the recommended tyre pressure
(Y page 264).
If you are driving with the emergency spare
wheel fitted, the tyre pressure monitor cannot
function reliably. Only restart the tyre pressure
monitor when the defective wheel has been
replaced with a new wheel. All fitted wheels
must be equipped with functioning sensors. Wheel and tyre combinations
You can ask for information regarding permitted
wheel-tyre combinations at a Mercedes-Benz
Service Centre.
! 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. 272
Wheel and tyre combinationsWheels and tyres

The recommended tyre pressures can be found
in the tyre pressure table on the fuel filler flap.
For further information on tyre pressure, see
(Y page 264). 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 tyres on all wheels at a
given time (summer tyres, winter tyres)
Exception: it is permissible to fit a different
type or make in the event of a flat tyre. Emergency spare wheel
Important safety notes
G
WARNING
The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting a spare wheel/emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of accident.
To prevent hazardous situations:
R Adapt your driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being
replaced.
R Only use a spare wheel/emergency spare
wheel briefly if the dimensions are different to those of the wheel being replaced.
R Do not switch off ESP ®
.
R Have the spare wheel/emergency spare
wheel in question replaced at the nearest
qualified specialist workshop. Make sure
that the wheel/tyre dimensions and tyre
type are correct.
When using an emergency spare wheel or spare wheel of a different size, you must not exceed
the maximum speed of 80 km/h.
Snow chains must not be fitted to emergency
spare wheels. General notes
You can ask for information regarding permitted emergency spare wheels 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 264).
The value on the wheel is valid.
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed lim- itation specified on the emergency spare wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
i If you are driving with the emergency spare
wheel fitted, the tyre pressure monitor cannot function reliably. Only restart the tyre pres-
sure monitor when the defective wheel has
been replaced with a new wheel.
If an emergency spare wheel is fitted, for a few minutes the system may continue to show the
tyre pressure of the wheel that has been
removed. The value displayed for the position
where the emergency spare wheel is fitted is
not the same as the current tyre pressure of
the emergency spare wheel. Removing the collapsible emergency
