Pump up the tyre again.
Af ter a maximum of ten minu testh e tyre
pressure must be at least 200 kPa (2.0 bar/
29 psi). &
WARNING Risk of accident due tothe
specified tyre pressure not being
attained
If th e minimum tyre pressure is not reached
af te rth e specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this ins tance.
The braking and driving characteristics may
be great lyimpaired. #
Do not continue driving. #
Consult a qualified specialist workshop. If, af
terte n minutes, a tyre pressure of
200 kPa (2.0 bar/29 psi) has been attained: &
WARNING Risk of accident from driving
wi th sealed tyres
A tyre temp orarily sealed with tyre sealant
impairs the handling 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. +

Note
s on noise or unusual handling charac‐
te rist ics
Make sure there are no vibrations, noises or
unusual handling characteristics when theve hi‐
cle is in motion. This may indicate that the
wheels or tyres are damaged. Hidden tyre dam‐
age could also be causing the unusual handling
ch aracteristics.
If yo u suspect that a tyre is defective, reduce
yo ur speed immediately and ha vethe tyres and
wheels checked at a qualified specialist work‐
shop. Note
s onregular lyinspecting wheels and
tyres &
WARNING Risk of inju rydue todamaged
tyres
Damaged tyres can cause tyre pressure loss. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. &
WARNING Risk of aquaplaning due to
insuf ficient tyre tread
Insu fficient tyre tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hi‐
cle is not adap tedto suit the conditions. #
Thus, you should regularly check the
tread de pth and the condition of the
tread across the entire width of all
tyres.
Minimum tread dep thfor:
R Summer tyres: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legally-prescribed limit for
th e minimum tread dep thisreached. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, for
ex ample, prior toa long journey or driving off-
ro ad:
R Check the tyre pressure (/ page 396).
R Visually inspect wheels and tyres for dam‐
age.
R Check theva lve caps.
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 u ha vefitted snow chains tothe front
wheels, the snow chains may drag against
th eve hicle body or chassis components.
This could cause damage totheve hicle or
th e tyres. Wheels and tyres

hicles with a tyre pressure monitoring
sy stem: electronic component parts are
located in the wheel. Tyre-fitting tools should
not be applied in the area of theva lve.
The tools could damage the electronic com‐
ponent parts. #
Have the tyres changed at a qualified
specialist workshop onl y. *
NO
TEDama getosummer tyres at low
ambient temp eratures At
low ambient temp eratures, tears could
fo rm when driving with summer tyres, caus‐
ing permanent damage tothe tyre. #
Attemp eratures below 7 °C use i
M+S- tyres. Ac
cessory pa rts th at are not appr ovedfo ryo ur
ve hicle byMercedes-Benz or are not being used
cor rectly can impair the operating saf ety.
Before pu rchasing and using non-appr oved
accesso ries, visit a qualified specialist workshop
and enquire about:
R Suitability
R Legal stipulations
R Factory recommendations &
WARNING Risk of accident wi thhigh
per form ance tyres
The special tire tread in combination with the
optimised tyre compound means that the
ri sk of skidding and aquaplaning on wet
ro ads is inc reased.
In addition, the tyre grip is greatly reduced at
a low outside temp erature and tyre running
te mp erature. #
Switch on the ESP ®
and adapt your
driving style accordingly. #
Use i M+S tyres at outside temp er‐
atures of less than 10 °C. #
Only use the tyres forth eir intended
purpose. Obser
vethefo llowing when selecting, fitting and
re placing tyres:
R Countr y-specific requirements for tyre
appro valth at define a specific tyre type for
yo ur vehicle. 402
Wheels and tyres

R
Furthermore, the use of cer tain tyre types in
cer tain regions and areas of operation can
be highly beneficial.
R Only use tyres and wheels of the same type
(summer tyres, winter tyres, MOEx tended
tyres) and the same make.
R Only fit wheels of the same size on one axle
(left and right).
It is only permissible tofit a di fferent wheel
size in theeve nt of a flat tyre in order to
drive tothe specialist workshop.
R Do not make any modifications tothe brake
sy stem, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may in validate theve hicle's
ge neral operating pe rmit.
R Vehicles with a tyre pressure monitoring
sy stem: allfitted wheels mu stbe equipped
with functioning sensors forth e tyre pres‐
sure monitoring sy stem.
R Attemp eratures below 7 °C use winter tyres
or all-season tyres mar kedi M+Sfor all
wheels. Wi
nter tyres pr ovide the best possible grip in
wintry road conditions.
R For M+S tyres, only use tyres with the same
tread.
R Obser vethe maximum permissible speed for
th e M+S tyres fitted.
If th e tyre's maximum speed is below that of
th eve hicle, this must be indicated byan
appropriate label in the driver's field of
vision.
R Run in new tyres at moderate speeds forthe
fi rs t10 0 km.
R Replace the tyres af ter six years at the latest,
re ga rdless of wear.
R 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. %
You can permanently limit the maximum
ve hicle speed for driving with winter tyres
(/ page 179).
