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

WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this instance. Damaged tyres and atyre
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified

the TIREFI Tsticker must be affixed to the
instrument cluster in the driver's field of
vision.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the tyre inflation compressor.
The tyre pressure must now be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tyre pressure is not reached
after driving for ashort period, the tyr eistoo
badly damaged. The tyr esealant can not
re pair the tyr einthis instance. Damaged tyres
and atyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.

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

General notes
Have your vehicle winterproofed at aqualified
specialist worksho patthe onset of winter.
Observ ethe notes in the "Changin gawheel"
section (Y page 404). Driving wit
hsummer tyres
At temperatures belo w+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 typ eofdamage. M+S tyres
G
WARNING
M+S tyres with atyre tread depth of less than
4mma re not su itable for use in winter as they
do not provid esufficient traction. There is a
risk of accident.
M+S tyres with atrea ddepth of less than
4mmm ust be replaced.
At temperatures below +7 †, use winter tyres
or all-seas ontyres.B oth types of tyr eare
identified by th eM+S marking.
Onl ywinter tyres bearing the isnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintr yroad con-
ditions.
Only these tyres will allow drivin gsafety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. Thes etyres have been devel-
ope dspecifically for driving in snow.
Use M+S tyres of the same mak eand tread
on all wheels to maintain safe handling char-
acteris tics.
Alway sobserv ethe maximum permissible
speed specifie dfor the M+S tyres you have
fit ted.
If you fit M+S tyres that have alower maxi-
mu mp ermissible speed than that of the vehi-
cle, affix acorresponding warnin glabel in the
driver' sfield of vision. This can be obtained
at aq ualified specialist workshop.
Under these circumstances, you should also
restrict the maximum spee dofthe vehicle
usin gpermanen tSPEEDTRONIC so that it
does not exceed the maximu mpermissible
speed for the M+S tyres(Y page 198).
