Vehicles with Mercedes me connect: you
can make a call for breakdown assi stance via
th eove rhead control panel in the case of a
breakdown (0013 page 346).
R Allvehicles: change the wheel

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. 0007
Do not exceed the permissible maxi‐
mum speed. 0007
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. 0007
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 0007
After driving in emergency mode ha ve
th erims checkedby aqu alified special‐
ist workshop with rega rd totheir fur ther
use. 0007
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. Yo
u can recognise MOExtended tyres bythe
MOExtended marking which appears onthe 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. Breakdown assis

Fu lly laden 30 kmThe 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

Tyre inflation compressor
2 Tyre sealant bottle
0009 Depending on the po wer category (LK), the
tyre inflation compressor weighs as follo ws:
R LK1 – 12V/10 A,120W, 0.8 kg
R LK2 – 12V/15 A,180W, 0.9 kg
Yo u can find information on the po wer cate‐
gory (LK) and/or electrical de tails on the
back of the tyre inflation compressor.
The tyre inflation compressor is mainte‐
nance-free. If there is a malfunction, please
conta ct aqualified specialist workshop. Using
the TIREFIT kit Re
quirements:
R Tyre sealant bottle
R TIREFIT sticker
R Tyre inflation compressor
R Gloves (depending on theve hicle equipment)
TIREFIT kit storage location: (0013 page412)
Yo u can use TIREFIT tyre sealant toseal per fora‐
tion dama geof up to4 mm, particularly those in
th e tyre conta ct surface. You can use TIREFIT in
outside temp eratures down to-20 °C. 000A
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
lar gerth an those pr eviously mentioned.
R the wheel rim is dama ged. 412

0007
Very slowly drive forw ards or reve rse appr ox‐
imately 10m. 0007
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). 000A
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. 0007
Do not drive on. 0007
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: 000A
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. 0007
Adapt your driving style according lyand
drive carefull y. 0007
Do not exceed the maximum speed
limit with a tyre that has been repaired
using tyre sealant. 0007
Obser vethe maximum permissible speed for
a tyre sealed with tyre sealant 80 km/h. 0007
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.
000E NO
TEStaining from leaking tyre sealant Af

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 000A
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. 0007
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 (0013 page 432).
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 000A
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. 0007
Neverfit snow chains on the front
wheels. 0007
Only fit snow chains on there ar wheels
in pairs. 000E

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 000A
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. 0007
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
