Do not drive on with a flat tyre. #
Chan getheflat tyre immediately with
an emer gency spa rewheel or spare

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 551).
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 553). 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 (/ page477).
R Allvehicles: change the wheel
(/ page 584).
% The emer gency spa rewheel is only available
in cer tain countries. Note

WARNING Risk of accident when driving
in eme rgency mode
When driving in emer gency mode, the han‐
dling characteristics are impaired. e.g. when
cornering, when accelerating stronglyand
when braking. #
Do not exceed the permissible maxi‐
mum speed. #
Avoid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, 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 ksin tire 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 tire 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. Breakdown assis
tance 551

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
wa rning sy stem.
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
gency
mode af ter the pressure loss warning: Load condition Driving distance pos‐
sible in emergency
mode
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

Breakdown assis tance

Do not swit
choff 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/
29 psi).
If tyre sealant leaks out, make sure you clean the
af fected area as quickly as possible. It is prefera‐
ble touse clear water.
If yo uge t tyre sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene.
If, af terte n minutes, a tyre pressure of
200 kPa (2.0 bar/29 psi) has not been ach‐
ie ve d: #
Switch off the tyre inflation compressor. #
Unscr ew thefilling hose from theva lve of the
defective tyre.
Please no tethat tyre sealant may leak out when
unscr ewing thefilling hose. #
Drive forw ards or reve rseve ry slowly for
appr oximately 10m. #
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/

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 rth e specified time, the tyre is too badly
damaged. 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
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.

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

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 (/ page571).
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

Wheels and tyres

#
Switch on the ESP ®
and adapt your
driving style accordingly. #
Use M+S tyres at outside temp eratures
of less than 50 °F. Obse
rveth efo 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.
Fu rthermore, 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 Only fit tyres of the cor rect size onto the
wheels. 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 is is below theve hicle's maximum speed,
th is 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 245).
