th MOExtended tyres (run-flat tyres), you can
continue todrive your vehicle even if there is a
tot al loss of pressure in one or more tyres. How‐
eve r,th e tyre af fected must not show any clearly
visible damage. Yo
u can recognise MOExtended tyres bythe
MOExtended marking which appears on the side
wa ll of the tyre.
Ve hicles with tyre pressure loss warning sys‐
te m: MOExtended tyres may only be used in
conjunction wi than activated tyre pressure loss

If a pressure loss warning message appears in
th e multifunction display:
R Check the tyre for dama ge.

If a tyre has gone flat and cannot be replaced
with an MOEx tended tyre, you can use a stand‐

WARNING Risk of accident when using
tyre sealant
In thefo llowing situations, the tyre sealant is
unable toprov ide suf ficient breakdown assis‐
ta nce, as it is unable toseal the tyre prop‐
erly:
R there are cuts or punctures in the tyre
larger than those pr eviously mentioned.
R the wheel rim is dama ged.
R you ha vedriven at very low tyre pres‐
sures or on a flat tyre. #
Do not drive on. #
Consult a qualified specialist workshop. &
WARNING Risk of inju ryand poisoning
from tyre sealant
Ty re sealant is hazardous tohealth and cau‐
ses ir rita tion. Do not allow it tocome into
contact wi thyour skin, eyes or clo thing, and 440
Breakdown assis tance

Damaged tyres and a tyre pressure
that is
to o low can significantly impair braking and
handling characteristics. #
Do not drive on. #
Consult a qualified specialist workshop. If, af
terte n minutes, a tyre pressure of
200 kPa (2.0 bar/29 psi) has been achie ved: #
Switch off the tyre inflation compressor. #
Unscr ew thefilling hose from theva lve of the
defective tyre. &
WARNING Risk of accident from driving
wi th sealed tyres
A tyre temp orarily sealed with tyre sealant
impairs driving characteristics and is not
suitable for higher speeds. #
Adapt your driving style according lyand
drive carefull y. #
Do not exceed the maximum speed
limit with a tyre that has been repaired
using tyre sealant. #
Obser vethe maximum permissible speed for
a tyre sealed with tyre sealant 80 km/h. #
Affix th e upper section of the TIREFIT sticker
to the instrument clus ter in a location where
it will be easi lyseen bythe driver.
* NO
TEStaining from leaking tyre sealant Af
ter use, excess tyre sealant may leak out
from thefilling hose. #
Therefore, place thefilling hose in the
plastic bag that con tained the TIREFIT
kit. +

Have the tyre sealant bottle disposed of
professionall y,e.g. at a Mercedes-Benz
Service Centre. #
Stow th e tyre sealant bottle, the tyre inflation
compressor and thewa rning triangle. #
Pull away immediatel y. #
Stop driving af ter appro ximately ten minu tes
and check the tyre pressure using the tyre
inflation compressor.
The tyre pressure must now be at least
13 0 kPa (1.3 bar/19 psi). &
WARNING Risk of accident due tothe
specified tyre pressure not being ach‐
ie ved
If th e specified tyre pressure is not achie ved
af te r a brief drive, the tyre is too badly dam‐
aged. The tyre sealant cannot repair the tyre
in this ins tance.
Dama ged tyres and a tyre pressure that is
to o low can significantly impair braking and

Note
s on noise or unusual handling charac‐
te rist ics
While driving, pay attention tovibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tyres are damaged. If you suspect that a tyre is
defective, reduce your speed immediatel y.Stop
th eve hicle as soon as possible tocheck the
wheels and tyres for dama ge. Hidden tyre dam‐
age could also be causing the unusual handling
ch aracteristics. If youfind no signs of damage,
ha ve the tyres and wheels checked at a qualified
specialist workshop. Note
s onregular lyinspecting wheels and
tyres &
WARNING Risk of accident from dam‐
aged tyres
Dama ged tyres can cause tyre pressure loss.
As a result, you could lose cont rol of your
ve hicle. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, e.g.
prior toa long journey or driving off- road:
R Check the tyre pressure (→ page 459).
R Visually inspect tyres and wheels for dam‐
age.
R Check theva lve caps.
The valves must be pr otected against mois‐
ture and dirt bytheva lve caps appr oved
especially foryo ur vehicle byMercedes-Benz.
R Visual check of the tyre tread dep thand the
tyre contact su rface across the entire width.
The minimum tread dep thfor summer tyres
is 3 mm and for winter tyres 4 mm. Note
s on snow chains &
WARNING Risk of accident due toincor‐
re ct snow chain fitting
If yo ufit snow chains tothere ar wheels, the
snow chains may grind against theve hicle
body or chassis components.
This could cause damage totheve hicle or

When replacing with tyres that do not
fe ature run-flat characteristics: vehicles
with MOExtended tyres are not equipped
with a TIREFIT kit at thefa ctor y.Equip the
ve hicle with a TIREFIT kit af terre placing with
tyres that do not feature run-flat characteris‐
tics, e.g. winter tyres.

s on inter changing wheels &
WARNING Risk of inju rythro ugh dif fer‐
ent wheel sizes
Inter changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions may se
verely impair the driving characteris‐
tics.
The disk brakes or wheel suspension compo‐
nents may also be damaged. #
Rotate front and rear wheels on lyifthe
wheels and tyres are of the same
dimensions. Inter
changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions can
re nder thege neral operating pe rmit in valid.
The wear pat tern s on the front and rear wheels
dif fer:
R Front wheels wear more on the shoulder of
th e tyre
R Rear wheels wear more in the cent reofthe
tyre
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5,000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for
th e wheels. It is imperative
toobser vethe instructions and
saf ety no tes on "Wheel change" when doing so. Note
s onstoring wheels R
Afterre moving wheels, store them in a cool,
dry and preferably dark place.
R Protect the tyres from conta ct withoil,
grease or fuel. Overview of
the ty re-change tool kit Apart from some countr
y-specific variants, vehi‐
cles are not equipped with a tyre-change tool kit.
