R there are tears in the sidewall softhe tyre.
After driving in emergency mode, have the
whee lrims checked at aquali fied specialist
workshop with regar dtotheir furthe ruse. The
fault ytyre must be replaced.
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or mor etyres.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning syste morwith an activ etyre pres-
sure monitor.
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
laden, and approximatel y30kmwhen the
vehicle is fully laden.
In addition to the vehicle load, the drivin gdis-
tance possible depends upon:
R speed
R road condition
R outside temperature
The drivin gdistance possible in run-flat mode
may be reduced by extrem edriving condi-
tions/manoeuvres ,oritcan be increased
through amoderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyr epressure loss warning
appe arsint he multifunction display.
You must not exceed amaximum spee dof
80 km/h.
i When replacing one or all tyres, make
sure tha tyou only use tyres marked
"MOExtended". Make sure that you only
use the size of tyr especified for the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory.
It is therefore recommended that you addi-
tionally equip your vehicle with aTIREFIT kit
if yo ufit tyres that do not featur erun-flat
characteristics, e.g. winter tyres. ATIREFIT kit can be obtaine
dfrom aqualified spe-
cialist workshop. TIREFIT kit
Usin gthe TIREFIT kit TIREFIT is
atyre seal ant.
You can use TIREFIT to seal punctures of up
to 4m m, particularl ythose in the tyr etread.
Yo uc an use TIREFI Tatoutside temperatures
down to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on aflat tyre.
There is arisk of accident.
Do not drive any further. Contact aqualified
specialist workshop. G
WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not
inhale TIREFIT fumes. Keep tyre sealant away
from children. There is arisk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately. Flat tyre

emergenc yspare wheel or spare wheel, or
consult aqualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyre s(tyres
with run-flat charac teristics).
Accessorie sthat ar enot approved for your
vehicle by Mercedes-Ben zorare not be ing

R factory recommendations
Information on the dimensions and types of
wheels and tyres for your vehicle can be
found in the "Wheel/tyre combinations" sec-
tion (Y page 409).
Information on air pressure for the tyres on
your vehicle can be found:
R on the tyre pressure label on the fuel filler
flap (Y page 175)
R in the "Tyre pressure" section
R under "Tyre pressure" (Y page 399)
Modification work on the brake system and
wheels is not permitted. The use of wheel
spacers or brake dust shields is not permit-
ted. This invalidates the general operating
permit for the vehicle.
i Further information on wheels and tyres
can be obtained at any qualified specialist
workshop. Operation
Information on driving
Check the tyre pressures when the vehicle is
heavily laden and, if necessary, adjust.
While driving, pay attention to vibrations,
noises and unusual handling charac teristics,
e.g .pulling to one side .This ma yindicate that
the wheels or tyres are damaged. If you sus-
pect that atyre is defective, reduce your
speed immediately. Stop the vehicle as soon
as possibl etocheckthe wheels and tyres for
damage. Hidden tyr edamage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tyres
and wheel schecked at aqualified specialist
workshop.
When parking your vehicle, make sure that
the tyres do not get deformed by the kerb or 396

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,
ma ybed amaged. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss .Asaresult,you coul dlose control
of your vehicle. There is arisk of accident.
Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
Regularly check the wheels and tyres of your
vehicle for damage at least once amonth, as
well as after drivin goff-road or on rough
roads .Damaged wheels can cause aloss of
tyr ep ressure. Pa yparticular attention to
damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on 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 397). If necessary, turn
the front wheelst ofull lock in order to inspect
the inner side of the tyre surface.
All wheel smust have avalve 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 by
Mercedes-Benz for your vehicle. 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 399).
Observe the notes on the emergenc yspare
wheel (Y page 414). The service life of tyres depends on various
factors, including the following:
R
driving style
R tyr ep ressure
R tyre mileage Tyre tread
G
WARNING
Insufficient tyre trea dwill 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 particular
where speed is not adapted to suit the driving
conditions. There is arisk 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: 3mm
R M+S tyres: 4mm
For safety reasons ,replace the tyres before
the legally prescribed limi tfor the minimum
tyr etrea ddepth is reached.. Selecting, fitting and replacing ty
res
R Only fi ttyres and wheels of the same type
and make.
R Only fit tyres of the correc tsize ont othe
wheels.
R Run in new tyres at moderate speeds for
the first 10 0km. They onl yreach their full
performanc eafter this distance.
R Do not drive wit htyres which have too little
tread depth .This otherwise significantly
reduce sthe traction on wet roads (aqua-
planing).
R Replace the tyres after six year satthe lat-
est, regardless of wear. Operation

Snow chains
G
WARNING
If you hav efitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tyres.
There is arisk of an accident.
To avoid hazardous situations:
R never fit snow chains on the fron twheels
R fit snow chains to the rea rwheels in pairs.
! You must driv eatraised vehicle level if
snow chains have been fitted. The vehicle
could otherwise be damaged. Observe the
information in the "AIRMATIC package"
section.
! Do not use the Adaptive Damping System
(ADS )sports mode if you have fit teds now
chains .The vehicle could otherwise be
damaged.
! On some tyr esizes there is not enough
space for snow chains. In order to prevent
damage to the vehicle or the tyres, observe
the "Tyre and wheel combinations" section
under "Tyres and wheels".
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or that are of acorre-
spondin gstandard of quality.
If you intend to fit snow chains ,please bear
the following points in mind:
R only use snow chains when the road sur-
face is completely snow-covered. Remove
the snow chains as soon as possible when
you come to aroad that is not snow- cov-
ered.
R do not exceed the maximu mpermissible
speed of 50 km /h. R
local regulations may restric tthe use of
snow chains. Observ ethe appropriate reg-
ulations if you wish to fit snow chains.
R snow chains cannot be fitted to all wheel-
tyr ec ombinations. Permissible wheel-tyre
combination s(Ypage 409).
i You may wish to deactivat eESP®
when
pull inga way with snow chains fitted
(Y page 67). This way you can allow the
wheels to spin in acontrolled manner ,ach-
ieving an increased driving force (cutting
action).
