Tyre tread
G
WARNING
Bea rinm ind that:
R tyre gri pdecrease srapidly on wetroads
when the tread depth is less than 3mm.
Thus ,you should repl acet yres that have
insufficient tread.
R winter tyres sho uld bereplaced when the
trea ddepth is 4mmorl ess as they no lon-
ger provide adequat egrip.
R thet rea donat yre may not wear evenly.
Thus ,you should regularly chec kthe tread
depth and the condition of the tread across
the entire widt hofall tyres. If necessary,
turn the fron twheels to full lock in order to
inspec tthe tyr etrea dm ore easily.
Otherwise, you coul dlose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Note
sons electing, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fittin gnew tyres, run them in at mod-
erat espeeds for the first 10 0km, as they
onl yreach their ful lperformanc eafter this
distance.
R Do not drive wit htyres which have too little
tread depth ,asthis significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six year satthe lat-
est, regardless of wear .This also applies to
the emergency spar ewheel/spar ewheel. MOExtended ty
res( tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allo wyou to continue drivin gthe vehicle even when one or mor
etyres los eall
air pressure.
MOExtended tyres may only be used in con-
junction with the tyre pressure loss warning
system or with the tyre pressure monitor and
on wheels specifically tested by Mercedes-
Benz.
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 the TIREFIT
kit if you fit tyres that do not feature run-
flat properties, e.g. winter tyres. ATIREFIT
kit can be obtaine dfrom aMercedes-Benz
Ser vice Centre.
Notes on driving with MOExtended tyres in
the event of aflat tyre can be found in the
"Breakdown assistance" section
(Y page 342). Winter operation
Points to remember
At the onset of winter ,have your vehicle win-
terproofed at aqualified specialist workshop,
e.g. at aMercedes-Ben zService Cent re.
Observe the notes in the "Changin gawheel"
section (Y page 363). Drivin
gwith summer ty res
At temperatures below +7 †, summer tyres
los ee lasticit yand therefore traction and
braking power; chang ethe tyres on your vehi-
cle to M+S tyres .Using summer tyres at very
cold temperatures could cause tears to form,
thereby damagin gthe tyres permanently.
Mercedes-Ben zcannot accept responsibility
for this type of damage. Winter operation

M+S tyres
At temperature sbelo w+ 7† ,use winter tyres
or all-season tyres .Both 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 driving
safet ysystems such as ABS and ESP ®
to
function optimally in winter, as thes etyres
have been designed specifically for driving on
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
WARNING
M+S tyres with atrea ddepth of less than
4mmm ust be replaced. They are no longer
suitable for winter use and can no longer pro-
vide sufficien tgrip. This could cause you to
lose control of your vehicle and cause an acci-
dent.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres which have alower max-
imu mpermissible speed than that of the vehi-
cle, affix an appropriate warning sign in the
driver' sfield of vision. This can be obtained
at aq ualified specialist workshop, e.g. at a
Mercedes-Ben zService Centre.
Under these circumstances, you should also
restrict the maximu mspeed of the vehicle
using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres(Y page 174).
When you have fitted the M+S tyres:
X Check the tyr epressures (Y page 359).
X Restart th etyre pressure los swarning sys-
tem (Y page 360). G
WARNING
If you fit the spare wheel when driving with M
+S tyres, bear in mind that driving stability will be impaired due to unstable cornerin
gchar-
acteristic scaused by the different tyres. You
shoul dtherefore adapt your drivin gstyle and
drive carefully.
Have the spare whee lreplaced at the nearest
qualified specialist workshop which has the
necessar yspecialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use aMercedes-Benz
Ser vice Centre for thi spurpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at aqualified
specialist workshop. Snow chains
For safety reasons ,Mercedes-Benz recom-
mends that you only use snow chain sthat
hav ebeen specially approved for your vehicle
by Mercedes-Benz ,orthat ar eofac orre-
spondin gstandard of quality.
! Vehicle swith the ON&OFFROAD package
or the AIRMATIC package: do not drive in
ADS SPORT mode when drivin gwith snow
chains fitted.
If you intend to fit snow chains, please bear
the following point sinmind:
R it is not permissible to attac hsnow chains
to all wheel-tyre combinations ;see the
information under "Wheel/tyre combina-
tion s"int he "Wheels and tyres" section.
R snow chains must not be fit tedtoe mer-
gency spare wheels ,e.g. a"Minispare"
emergency spar ewheel.
R fit snow chains only in pair sand only to the
rear wheels .Observ ethe manufacturer's
installation instructions.
! Vehicle swith steel wheels: if you wish
to fit snow chains to steel wheels, make
sure that you remove the respective
wheels' hubcaps first .The hubcaps may
otherwise be damaged. 358

obtained from any Mercedes-Benz Service
Centre.
! Retreaded tyres ar eneither tested nor
recommended by Mercedes-Benz, since
previous damage can nota lways be detec-
ted on retreaded tyres. As aresult,
Mercedes-Benz can notg uarantee 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 acertain wheel size, the lower the ride
comfor tisonp oor roadsurfaces. Roll com-
fort and suspensio ncomfort ar ereduced
and the risk of damage to the wheels and
tyres as aresult of driving over obstacles
increases.

the inside of your vehicle's fuel filler flap.
