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

wheel (Y page 414). 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 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 and on wheels specificall ytes-
ted by Mercedes-Ben z.
No tes on driving with MOExtended tyres with
af lat tyre (Y page 378).
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory.
It is therefore recommended that you addi-
tionally equi pyour 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. Winter 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).
When you have fit tedt he M+S tyres:

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®
