WARNING
Tyres, wheels or accessories whic hhaven ot
been approved by Mercedes- Benz foryour
vehicle or are not used as they should be, can
impair driving safety. As aresult, you could
cause an accident .Befor epurchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tions at aMercedes-Benz Ser vice Centre.
Modificatio nwork on the brake system and
wheels is not permitted, nor is the use of
spacer plate sorbrake dust shields. This inva-
lidates th eGeneral Operatin gPermit for the
vehicle.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Ser vice Centre. Oper
ation Notes on driving
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics ,e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that atyre is defective,
reduce your speed immediately. Stop the vehicle as soo
naspossible to chec kthe
wheels and tyres for damage. Hidden tyre
damage could also be causing the unusual
handling characteristics. If you fin dno
signs of damage, hav ethe wheels and tyres
examined at aqualified specialist work-
shop, e.g. aMercedes-Ben zService
Cent re.
R When parkin gyour 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 eleva-
tions, tr ytodosos lowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Notes on regularly inspecting wheels
and tyres
R Regularly chec kthe wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
crack sorseverecorrosion on wheels), at
least ever y14d ays, as well as after driving
off-road or on rough roads. Damaged
wheels can cause aloss of tyr epressure.
R Regu larly check th etyre tread depth and
the conditio nofthe tread across the whole
widt hofthe tyr e(Ypage 357). If neces-
sary, tur nthe front wheels to full lock in
orde rtoi nspect the inner sid eofthe tyre
surface.
R All wheels must hav eavalve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitorin gsystems) othe rthan
the standar dvalve cap or other valve caps
approved by Mercedes-Ben zfor your vehi-
cle.
R Regularly chec kthe pressur eofall the tyres
including the emergenc yspare wheel or the
spare wheel, particularly prior to long trips,
and correc tthe pressur easnecessary

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.
