#Changetheflat tire immediately with
th e emer gency spa rewheel or spare
wheel. Alternativel y,consult a qualified

Ti re s with run-flat characteristics:
#Observ eth e information and warning
no tes on MOExtended tires (run-flat
tires).
In theeve nt of a flat tire, thefo llowing options
are available depending on your vehicle's equip‐
ment:
RVe hicles with MOExtended tires: it is pos‐
sible tocontinue the journey for a short
period of time. Make sure you observ eth e
no tes on MOExtended tires (run-flat tires)
(
→page 341).
RVe hicles with a TIREFIT kit: you can repair
th e tire so that it is possible tocontinue the
jou rney for a short period of time. Todo this,
use the TIREFIT kit (
→page 342).
RVe hicles with Mercedes-Benz
mbrace®(USA only): you can make a call for Ro
adside Assis tance via theove rhead control
panel in the case of a breakdown
(

RAll vehicles: change the wheel
(→page 384).
MOExtended tires (tires with run-flat proper‐
ties)
& WARNING Risk of accident when driving
in li mp-home mode
When driving in emergency mode the han‐
dling characteristics are impaired, e.g. when
cornering, when accelerating stronglyand
when braking.
#Do not exceed the specified maximum
speed.
#Av oid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road).
This applies, in part icular,toa loaded
ve hicle.
#Stop driving in the emer gency mode if
yo u notice:
Rbanging noise
Rvehicle vibration
Rsmoke which smells like rubber
Rcontinuous ESP®inter vention
Rcrac 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.
With MOExtended tires (run-flat tires), you can
continue todrive your vehicle even if there is a
tot al loss of pressure in one or more tires. How‐
eve r,th e tire af fected must not show any clearly
visible damage.
Yo u can recognize MOExtended tires bythe
MOExtended marking which appears onthe side
wa ll of the tire.

Vehicles with tire pressure monitoring sys‐
te m: MOExtended tires may only be used in con‐
junction wi than activated tire pressure monitor‐
ing sy stem.
If a pressure loss warning message appears in
th e multifunction display:
RCheck the tire for dama ge.
RIf driving on, obser vethefo llowing no tes.
Driving distance possible in limp-home mode
af te r the pressure loss warning:
Load condition Driving distance pos‐
sible in limp-homemode
Pa rtially laden 50 miles (80 km)
Fu lly laden 19miles (30 km)
RThe driving dis tance possible in li mp-home
mode may vary depending on the driving
st yle.
RMaximum permissible speed 50 mph
(80 km/h). If a tire has gone
flat and cannot be replaced
with an MOEx tended tire, you can use a stand‐
ard tire as a temp orary measure.
Using the TIREFIT kit
Ha ve thefo llowing readily available:
RTire sealant bottle
REnclosed TIREFIT sticke r
RTire inflation compressor
Yo u can use TIREFIT tire sealant toseal punctu‐
re s of up to0.16 in (4 mm), particular lythose in
th e tire conta ct surface.You can use TIREFIT in
outside temp eratures down to-4 °F (-20 °C).

WARNING Risk of accident when using
tire sealant.
In thefo llowing situations, the tire sealant is
unable toprov ide suf ficient breakdown assis‐
ta nce, as it is unable toseal the tire proper ly:
RThere are cuts or punctures in the tire
lar gerth an those pr eviously mentioned.
RThe wheel rim is dama ged.
RYo u ha vedriven at a very low tire pres‐
sure or on a flat tire.
#Do not continue driving.
#Consult a qualified specialist workshop.
&
WARNING Risk of injury and poisoning
from tire sealant
The tire sealant is harmful and causes ir rita ‐
tion. Do not allow it tocome into contact
wi th th e skin, eyes or clo thing, and do not
swallow it. Do not inhale tire sealant fumes.
Ke ep the tire sealant away from children.
If yo u come into contact withth e tire sealant,

#Remo vethe cap from valve 7 onthe defec‐
tive tire.
#Scr ew filling hose 8onto valve 7.
#Insert plug 4into a 12V soc ket in your
ve hicle.
#Switch the ignition on.
#Press on and off switch 3onthe tire infla‐
tion compressor.
The tire inflation compressor is switched on.
The tire is inflated. Fir st, tire sealant is pum‐
ped into the tire. The pressure may brief ly
ri se toappr oximately 500 kPa (5 bar/73 psi). Do not switch off
the tire inflation compres‐
sor du ring this phase.
#Let the tire inflation compressor runfo r a
maximum of ten minu tes.
The tire should then ha veattained a tire
pressure of at least 200 kPa (2.0 bar/
29 psi).
If tire sealant leaks out, make sure you clean the
af fected area as quickly as possible. It is prefera‐
ble touse clean water.
If tire sealant gets on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene.
If, af terte n minutes, a tire pressure of
200 kPa (2.0 bar/29 psi) has not been
re ached:
#Switch off the tire inflation compressor.
#Un scr ew thefilling hose from theva lve of the
defective tire.
Please no tethat tire sealant may leak out when
unscr ewing thefilling hose.
#Drive forw ards or back up very slowly for
appr oximately 33 ft(10 m).
#Pump the tire up again.
Af ter a maximum of ten minu testh e tire
pressure must be at least 200 kPa (2.0 bar/
29 psi).
& WARNING Risk of accident due tothe
specified tire pressure not being reached
If th e specified tire pressure is not reached
af te rth e specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this ins tance.
Dama ged tires and a tire pressure that is too
low can significantly impair braking and han‐
dling characteristics.
#Do not continue driving.
#Consult a qualified specialist workshop.

WARNING Risk of accident due tothe
specified tire pressure not being reached
If th e specified tire pressure is not reached
af te r a brief drive, the tire is too badly dam‐
aged. The tire sealant cannot repair the tire
in this ins tance.
Dama ged tires and tire pressure that is too
low can significantly impair the braking prop‐
erties and the handling characteristics.
#Do not continue driving.
#Consult a qualified specialist workshop.
