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. #
Chan getheflat tire immediately with an
emer gency spa rewheel or spare wheel.
Alternativel y,consult a qualified spe‐
cialist workshop. 356

Ti
re s with run-flat characteristics: #
Obse rveth 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:
R Vehicles with MOExtended tires: it is pos‐
sible tocontinue the journey for a short
period of time. Make sure you obse rvethe
no tes on MOExtended tires (run-flat tire)
(→ page 357).
R Vehicles with a TIREFIT kit: you can repair
th e tires so that it is possible tocontinue the
jou rney for a short period of time. Todo this,
use the TIREFIT kit (→ page 358).
R Vehicles with Mercedes me connect: you
can make a call forRo adside Assis tance via
th eove rhead control panel in the case of a
breakdown (→ page 302).
R Allvehicles: change the wheel
(→ page 400). 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 for MOExtended tires. #
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 tires (run-flat tire), 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 displa y,proceed as follo ws:
R Check the tire for dama ge.
R If driving on, obser vethefo llowing no tes. Breakdown assis
tance 357

Driving distance possible in eme

Pa rtially laden 50 miles (80 km)
Fu lly laden 19miles (30 km) The driving dis
tance possible in emergency
mode may vary depending on the driving style.
Obser vethe maximum permissible speed of
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

quirements:
R Tire sealant bottle
R Enclosed TIREFIT sticker
R Tire inflation compressor
R Disposable glov es
Yo u can use TIREFIT tire sealant toseal per fora‐
tion dama geof up to0.16 in (4 mm), particularly
th ose in the 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:
R There are cuts or punctures in the tire
lar gerth an those pr eviously mentioned.
R The wheel rim is dama ged.
R You 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 inju ryand 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 358

Switch on the ignition. #
Press on and off switch 3onthe tire infla‐

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 lea ksout, make sure you clean the
af fected area as quickly as possible. It is prefera‐
ble touse clear water.
If yo uge t tire sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene.
If a ti repressure of 180 kPa (1.8 bar/26 psi)
has not been attained af ter eight minutes: #
Switch off the tire inflation compressor. #
Unscr ew thefilling hose from theva lve of the
fa ulty tire.
Please no tethat tire sealant may leak out when
unscr ewing thefilling hose. #
Drive forw ards or reve rseve ry slowly for
appr oximately 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. #

WARNING Risk of accident from driving
wi th sealed tires
A tire temp orarily sealed with tire 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 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‐
