i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It
is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit can be obtained from a qualified spe-
cialist workshop. MOExtended tyres (tyres with run-flat
characteristics)
General notes With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres. The affected
tyre must not show any clearly visible dam-
age.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the
tyre wall. You will find this marking next to the
tyre size designation, the load-bearing capa-
city and the speed index.
MOExtended tyres may only be used in con-
junction with an activated tyre pressure loss
warning system or tyre pressure monitor.
If a pressure loss warning message
appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 276)
R check the tyre for damage
R if driving on, observe the following notes
The driving distance possible in run-flat mode is approximately 80 km when the vehicle is
partially laden and approximately 30 km
when the vehicle is fully laden. 334
Flat tyreBreakdown assistance

causing the unusual handling characteristics.
If you find no signs of damage, have the tyres
and wheels checked at a qualified specialist
workshop.
When parking your vehicle, make sure that
the tyres do not get deformed by the kerb or
other obstacles. If it is necessary to drive over
kerbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
may be damaged. Regular checking of wheels and tyres
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.
Regularly check the wheels and tyres of your
vehicle for damage at least once a month, as well as 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 wheels
Regularly check the tyre tread depth and the condition of the tread across the whole width
of the tyre (Y page 353). If necessary, turn
the front wheels to full lock in order 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
anything onto the valve other than the stand-
ard valve cap or other valve caps approved for
your vehicle by Mercedes-Benz. Do not fit any other valve caps or systems, e.g. tyre pres-
sure monitoring systems. Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 356).
Observe the notes on the emergency spare
wheel (Y page 380).
The service life of tyres depends on various
factors, 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 Operation
353Wheels and tyres
Z

tyre load rating and speed rating required for
your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These
requirements can stipulate a specific tyre
type for your vehicle. Furthermore, the use of certain tyre types 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 Only fit 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 334).
R Only fit tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for
the first 100 km. They only reach their full
performance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
R Replace the tyres after six years at the lat-
est, regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 380). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with an activated tyre pressure loss
warning system or with an activated tyre pres- sure monitor and on wheels specifically tes-
ted by Mercedes-Benz. Notes on driving with MOExtended tyres with
a flat tyre (Y page 334).
Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionallyequip your vehicle with a TIREFIT kit if you fit
tyres that do not feature run-flat characteris- tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop. 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 361). Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticity and therefore traction and
braking power. Change the tyres on your vehi- cle 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. 354
