WARNING Risk of accident due toaflat
tyre
A flat tyre se verely affects the driving charac‐
te rist ics as well as thesteering and braking
of theve hicle.
Ty res without run-flat characteristics: #
Do not drive with a flat tyre. #
Chan getheflat tyre immediately with
an emer gency spa rewheel or spare
wheel. Alternativel y,consult a qualified
specialist workshop.
Ty res with run-flat characteristics: #
Obse rveth e information and warning
no tes on MOExtended tyres (run-flat
tyres). In
theeve nt of a flat tyre, thefo llowing options
are available depending on your vehicle's equip‐
ment:
R Vehicles with MOExtended tyres: it is pos‐
sible tocontinue the journey for a short
period of time. Make sure you obse rvethe
no tes on MOExtended tyres (run-flat tyres)
(/ page 352).
R Vehicles with a TIREFIT kit: you can repair
th e tyre so that it is possible tocontinue the
jou rney for a short period of time. Todo this,
use the TIREFIT kit (/ page 353).
R Vehicles with Mercedes me connect: you
can make a call for breakdown assi stance via
th eov erhead control panel in the case of a
breakdown (/ page310).

WARNING Risk of accident when driving
in limp -home mode
Driving in emergency mode impairs the han‐
dling characteristics of theve hicle. #
Do not exceed the permissible maxi‐
mum speed of the MOEx tended tyres. #
Avoid any abrupt steering and driving
manoeuvres as well as driving over
obs tacles (kerbs, pot holes, off-road).
This applies, in pa rticular, toa loaded
ve hicle. #
Stop driving in the emer gency mode if
yo u notice:
R banging noise
R vehicle vibration
R smoke which smells like rubber
R continuous ESP ®
inter vention
R crac ksinthe tyre side walls #
After driving in emergency mode, ha ve
th erims checkedby aqu alified special‐ ist
workshop with rega rd totheir fur ther
use. #
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 monitoring sys‐
te m: MOExtended tyres may only be used in
conjunction wi than activated tyre pressure mon‐
itoring sy stem.
If a pressure loss warning message appears in
th e multifunction displa y,proceed as follo ws:
R Check the tyre for dama ge.
R If driving on, obser vethefo llowing no tes. Driving distance possible in emer

Pa rtially laden 80 km
Fu lly laden 30 km The driving dis
tance possible in emergency
mode may vary depending on the driving style.
Obser vethe maximum permissible speed of
80 km/h.
If a tyre has gone flat and cannot be replaced
with an MOEx tended tyre, you can use a stand‐
ard tyre as a temp orary measure. TIREFIT kit

The tyre is inflated. Fir st, tyre sealant is pum‐
ped into the tyre. The pressure may brief ly
ri se toappr oximately 500 kPa (5 bar/73 psi).
Do not switch off the ty reinflation compres‐
sor during this phase! #
Let the tyre inflation compressor runfo r a
maximum of ten minu tes.
The tyre should then ha veattained a tyre
pressure of at least 200 kPa (2.0 bar/

If tyre sealant leaks out, make sure you clean the
af fected area as quickly as possible. It is prefera‐
ble touse clean water.
If yo uge t tyre sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐

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.

WARNING Risk of accident with high
per form ance tyres
The special tyre tread in combination with
th e optimised tyre compound means that the
ri sk of skidding and hydroplaning 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 004D M+S tyres at outside temp er‐
atures of less than 10 °C. #
Only use the tyres forth eir intended
purpose. Obser

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

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.
