Tyre pressure reached G
WARNING
A tyre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed the specified maximum speed with a tyre that
has been repaired using tyre sealant.
The maximum permissible speed for a tyre
sealed with tyre sealant is 80 km/h. The upper
part of the TIREFIT sticker must be affixed to the

Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
Check wheels and tyres for damage at least
once a month. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure. Pay
particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on the
wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 335). If necessary, turn the
front wheels to full lock to make it easier to
inspect the inner side of the tyre surface.
All wheels must have a valve cap to protect the valve against dirt and moisture. Do not fit any-
thing onto the valve other than the standard
valve cap or other valve caps specially approved
for your vehicle by Mercedes-Benz. Do not fit
any other valve caps or systems, e.g. tyre pres- sure monitors.
Check the pressure of all tyres regularly as well
as prior to long trips. Adjust the tyre pressures
as necessary (Y page 337).
Observe the notes on the emergency spare
wheel (Y page 348).
The service life of a tyre depends on various fac-
tors, including the following:
R driving style
R tyre pressure
R mileage Notes on the tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces, the risk of aquaplaning increases, in particularwhere speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at differ- ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load rating and speed rating required for your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ments may stipulate a specific tyre type for your
vehicle. Furthermore, the use of a specific tyre
type in certain regions and areas of operation
can be highly beneficial. You can find further
information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at
any Mercedes-Benz Service Centre.
R Use only tyres and wheels of the same type
and make.
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe here the "MOExtended tyres (tyres
with run-flat characteristics)" section
(Y page 318).
R Fit only tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for the
first 100 km. They reach their full perform-
ance only after this distance. Operation
335Wheels and tyres Z
R
Do not drive with tyres that have too little
tread depth. This significantly reduces trac-
tion on wet roads (aquaplaning).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 348). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat char- acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one or more tyres.
MOExtended tyres may be used only in conjunc-tion with an activated tyre pressure loss warning
system or with an activated tyre pressure mon-
itor and only on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tyres with a
flat tyre (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
do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 342). Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage. G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damageand replace any damaged tyres immediately. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions. Only these tyres will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyres that have a lower maximum
permissible speed than that of the vehicle, affix
an appropriate warning label in the driver's field
of vision. This can be obtained at a qualified
specialist workshop.
Under these circumstances, you should also
restrict the maximum design speed of the vehi- cle using the permanent limiter to the maximumpermissible speed for the M+S tyres
(Y page 180). 336

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.
