WARNING Risk of accident due toaflat
tire
A flat tire se verely affects the driving charac‐
te rist ics as well as thesteering and braking
of theve hicle.
Ti re s without run-flat characteristics:
#Do not drive on with a flat tire.
#Change theflat tire immediately with
th e emer gency spa rewheel or spare
wheel. Alternativel y,consult a qualified
specialist workshop.
Ti re s with run-flat characteristics:
#Observ eth e information and warning
no tes on MOExtended tires (run-flat
tires).
Breakdown assis tance 393

Intheeve 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 394).
RVe hicles with a TIREFIT kit: you can repair
th e tire so that it is possible tocontinue the
journ eyfor a short period of time. Todo this,
use the TIREFIT kit (
→page 395).
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
(
→page 328).
RAll vehicles: change the wheel
(→page 437).
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.
Ve hicles 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.
394
Breakdown assis tance

RIf driving on, observethefo 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.
TIREFIT kit storage location
The TIREFIT kit is located under the trunk floor. Mercedes‑AMG
vehicles: observeth e no tes in
th e Supplement. Otherwise, you may not recog‐
nize dangers.
Plug-in hybrid: obser vethe no tes in the Supple‐
ment. Otherwise, you may not recognize dan‐
ge rs.

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,
obser vethefo llowing:
#Rinse off the tire sealant from your skin
immediately using water.
#If tire sealant gets into your eyes, thor‐
oughly rinse out theey es using clean
wate r.
#If tire sealant has been swallowe d,
immediately rinse out the mouth thor‐
oughly and drink plenty of water.Do not
induce vomiting and seek medical
attention immediately.
#Change out of any clo thes conta mina‐
te d with tire sealant immediatel y.
#If allergicreactions occur, seek medical
attention immediatel y.
*NO

tion compressor running too long
#Do not runth e tire inflation compressor

inter ruption.
Comply with the manufacturer's saf etyno tes on

#Place tire sealant bottle 1head down wards
into recess 2ofthe tire inflation compres‐
sor.
#Re mo vethe cap from valve 7 onthe defec‐
tive tire.
#Scr ew filling hose 8onto valve 7.
#Insert plug 4into a 12‑V‑sock etinyour
ve hicle.
#Switch on the ignition.
#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 eight minutes.
The tire should then ha veattained a tire
pressure of at least 180 kPa (1.8 bar/26 psi).
If tire sealant leaks out, make sureyou clean the
af fected area as quickly as possible. It is prefera‐
ble touse clean water.
If yo uge t tire sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene.
If atire pressure of 180 kPa (1.8 bar/26 psi)
has not been attained af ter eight minutes:
#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.
#Ve ry slowly drive forw ards or reve rse appr ox‐
imately 33 ft(10 m).
#Pump up the tire again.
Af ter a maximum of eight minutes the tire
pressure must be at least 180 kPa (1.8 bar/
26 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 from driving
wi th sealed tires
A tire temp orarily sealed with tire sealant
impairs the handling characteristics and is
not suitable for higher speeds.
#Ad apt your drivin gst yle according lyand

#Do notexceed the specified maximum
speed with a tire that has been repaired
using tire sealant.
Obser vethe maximum permissible speed for a
tire sealed with tire sealant 50 mph(8 0 km/h).

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.
In cases such as the one mentioned abo ve, con‐
ta ct an au thorized Mercedes-Benz Center. Or
call 1-800-FOR-MERC edes (inthe USA) or
1-800-387-0 100 (in Canada).
#Cor rect the tire pressure if it is still at least
13 0 kPa (1.3 bar/19 psi). See theTire and
Loading Info rmation placard on the driver's
side B‑pillar or the tire pressure table in the
fuel filler flap forva lues.
