The defective tyre must be replaced in
eve rycase. Wi
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 displa y,proceed as follo ws:
R Check the tyre for dama ge.

WARNING Risk of accident when using
tyre sealant
The tyre sealant may be unable toseal the
tyre properly, especially in thefo llowing
cases: R
there are lar gecuts or punctures in the
tyre (larger than damage pr eviously men‐
tioned)
R the wheel rims ha vebeen damaged
R afte r journe yswith very low tyre pressure
or with flat tyres #
Do not continue driving. #
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
do not swallow it. Do not inhale any vapours.
Ke ep the tyre sealant away from children.
Obser vethefo llowing if you come into con‐
ta ct wi th the tyre sealant: #
Rinse off the tyre sealant from your skin
using water immediatel y. 308

&
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.

TEStaining from leaking tyre sealant Af
ter use, excess tyre sealant may leak out
from thefilling hose. #
Therefore, place thefilling hose in the

Service Centre. #
Stow th e tyre sealant bottle and 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
attained
If th e specified tyre pressure is not reached,
th e tyre is too badly damaged. The tyre seal‐
ant cannot repair the tyre in this ins tance. The braking and driving
characteristics may
be great lyimpaired. #

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 326).
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

It is only permissible
tofit a di fferent wheel
size in theev ent 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 ked M+S for all
wheels.
Wi nter tyres bearing thei snowflake
symbol in addition tothe M+S marking pro‐
vide 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 194).

WARNING Risk of inju rythro ugh dif fer‐
ent wheel sizes
Inter changing the front and rear wheels can
se verely impair the driving characteristics.
The disk brakes or wheel suspension compo‐
nents may also be damaged. #
Onlyinter change the front and rear
wheels if the wheels and tyres ha vethe
