Notes on "Oat tires
&WARNING Risk of accident due to a "Oat
tire
A "Oat tire severely a"Mects the driving charac-
teristics as well as the steering and braking of
the vehicle.
Tires without run-"Oat characteristics: Do not drive with a "Oat tire.Change the "Oat tire immediately with an
emergency spare wheel or spare wheel.
Alternatively, consult a quali"Ned special-
ist workshop.
Tires with run-"Oat characteristics:
Observe the information and warning
notes on MOExtended tires (run-"Oat
tires).
In the event of a "Oat tire, the following options are
available depending on your vehicle\bs equipment:
= Vehicles with MOExtended tires: it is possible
to continue the journey for a short period of
time. Make sure you observe the notes on MOExtended tires (run-"Oat tires)
(  page 420).
= Vehicles with a TIREFIT kit: you can seal the
tire so that it is possible to continue the jour-
ney for a short period of time. To do this, use the TIREFIT kit (  page 421).
Breakdown assistance419

=Vehicles with Mercedes me connect: you can
make a call for breakdown assistance via the
overhead control panel in the case of a break-
down (  page 384).
= All vehicles: change the wheel (  page 467).\bThe emergency spare wheel is only available
in certain countries.
Notes on MOExtended tires (run-"Oat tires)
&WARNING Risk of accident when driving in
limp-home mode
When driving in emergency mode the handling
characteristics are impaired.
Do not exceed the speci"Ned maximum
speed of the MOExtended tires.Avoid any abrupt steering and driving maneuvers as well as driving over obsta-
cles (curbs, pot holes, o"M-road). This
applies, in particular, to a loaded vehicle.Stop driving in the emergency mode if
you notice:= Banging noise
= Vehicle vibration
= Smoke which smells like rubber
= Continuous ESP n
intervention
= Cracks in the tire side wallsA"ser driving in emergency mode, have
the rims checked by a quali"Ned specialist
workshop with regard to their further
use.The defective tire must be replaced in
every case.
With MOExtended tires (run-"Oat tires), you can
continue to drive your vehicle even if there is a
total loss of pressure in one or more tires. How-
ever, the tire a"Mected must not show any clearly
visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the side wall of the tire.
Vehicles with tire pressure monitoring system:
MOExtended tires may only be used in conjunc-
tion with an activated tire pressure monitoring system.
If a pressure loss warning message appears in the driver\bs display, proceed as follows:
= Check the tire for damage.
= If driving on, observe the following notes.
Driving distance possible in emergency mode
a"ser the pressure loss warning:Load conditionDriving distance possi-
ble in emergency modePartially laden50 miles (80 km)Fully laden19 miles (30 km)
The driving distance possible in emergency mode
may vary depending on the driving style. Observe the maximum permissible speed of 50 mph
(80 km/h).
If a tire has gone "Oat and cannot be replaced with
an MOExtended tire, you can use a standard tire
as a temporary measure.

TIREFIT kit storage location
Depending on the vehicle equipment, the storage
bag for the TIREFIT kit is located in the trunk or in the storage net on the le"s. Comply with the load-
ing guidelines (  page 142).
Using the TIREFIT kit
Requirements
= Tire sealant bottle and tire in"Oator compressor
are ready for use (  page 421).
= TIREFIT sticker is present.
= Gloves are present.
TIREFIT kit storage location: (  page 421)
You can use TIREFIT tire sealant to seal perfora-
tion damage of up to 0.16 in (4 mm), especially in
the tire tread. You can use TIREFIT in outside tem- peratures as low as -4°F (-20°C).
&WARNING Risk of accident when using
tire sealant
The tire sealant may be unable to seal the tire
properly, especially in the following cases:
= There are large cuts or punctures in the
tire (larger than damage previously men-
tioned)
= The wheel rims have been damaged
= A"ser journeys with very low tire pressure
or with "Oat tires
Do not continue driving.Consult a quali"Ned specialist workshop.&WARNING Risk of injury and poisoning
from tire sealant
The tire sealant is harmful and causes irrita-
tion. Do not allow it to come into contact with
the skin, eyes or clothing, and do not swallow it. Do not inhale tire sealant fumes. Keep the
tire sealant away from children.
If you come into contact with the tire sealant,
observe the following:Rinse o"M the tire sealant from your skin
immediately using water.If tire sealant gets into your eyes, thor- oughly rinse out the eyes using clean
water.If tire sealant has been swallowed, imme-
diately rinse out the mouth thoroughly
and drink plenty of water. Do not induce
vomiting and seek medical attention
immediately.Change out of any clothes contaminated
with tire sealant immediately.If allergic reactions occur, seek medical
attention immediately.*NOTE Overheating due to the tire in"Oation
compressor running too longDo not run the tire in"Oation compressor
for longer than ten minutes without inter- ruption.Breakdown assistance421

Comply with the manufacturer\bs safety notes on
the sticker on the tire in"Oation compressor.
Have the tire sealant bottle replaced at a quali"Ned
specialist workshop every "Nve years.Do not remove any foreign objects that have
entered the tire.A"Px part 1 of the TIREFIT sticker to the
instrument cluster within the driver\bs "Neld of
vision.A"Px part 2 of the TIREFIT sticker near the
valve on the wheel with the defective tire.Pull plug 6 with the cable and hose 5 out
of the tire in"Oation compressor housing.Push the plug of hose 5 into "Oange 4 of tire
sealant bottle 3 until the plug engages.Place tire sealant bottle 3 head downwards
into recess 2 of the tire in"Oation compressor.Remove the valve cap from valve 7 on the
faulty tire.Screw "Nlling hose 8 onto valve 7.Insert plug 6 into a 12 V socket in your vehi-
cle.Switch on the vehicle.Switch on the tire in"Oation compressor using
On/O"M switch 1.
The tire will be in"Oated. First, tire sealant will
be pumped into the tire. The pressure may
brie"Oy rise to approximately 500 kPa (5 bar/
73 psi).422Breakdown assistance

Do not switch o"M the tire in"Oation compressor
during this phase!Let the tire in"Oation compressor run for a max-
imum of ten minutes.
The tire should then have attained a pressure
of at least 200 kPa (2.0 bar/29 psi).
If tire sealant leaks out, make sure you clean the
a"Mected area as quickly as possible. It is prefera-
ble to use clean water.
If you get tire sealant on your clothing, have it cleaned as soon as possible with perchloroethy- lene.
If, a"ser ten minutes, a tire pressure of 200 kPa
(2.0 bar/29 psi) has not been attained:
Switch o"M the tire in"Oation compressor.Unscrew the "Nlling hose from the valve of the
defective tire.
Please note that tire sealant may leak out when
you unscrew the "Nlling hose.
Drive forwards or in reverse very slowly for
approximately 33 "s (10 m).Pump up the tire again.
A"ser a maximum of ten minutes, the tire pres-
sure must be at least 200 kPa (2.0 bar/
29 psi).&WARNING Risk of accident due to the
speci"Ned tire pressure not being achieved
If the speci"Ned tire pressure is not achieved
a"ser the speci"Ned time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance.
The braking characteristics as well as the driv- ing characteristics may be greatly impaired.
Do not continue driving.Consult a quali"Ned specialist workshop.
If, a"ser ten minutes, a tire pressure of 200 kPa
(2.0 bar/29 psi) has been attained:
Switch o"M the tire in"Oation compressor.Unscrew the "Nlling hose from the valve of the
defective tire.&WARNING Risk of accident from driving
with sealed tires
A tire temporarily sealed with tire sealant
impairs the handling characteristics and is not suitable for higher speeds.
Adapt your driving style accordingly and
drive carefully.Do not exceed the maximum speed limit with a tire that has been repaired using
tire sealant.Do not exceed the maximum permissible
speed of 50 mph (80 km/h) for a tire sealed
with tire sealant.*NOTE Staining caused by leaking tire seal-
ant
A"ser use, excess tire sealant may leak out
from the "Nlling hose.
Therefore, place the "Nlling hose in the
plastic bag that contained the TIREFIT
kit.Breakdown assistance423

professionally, e.g. at an authorized
Mercedes-Benz Center.Stow the tire sealant bottle and the tire in"Oa-
tion compressor.Pull away immediately.Stop driving a"ser approximately ten minutes
and check the tire pressure using the tire
in"Oation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).&WARNING Risk of accident due to the
speci"Ned tire pressure not being attained
If the speci"Ned tire pressure is not reached,
the tire is too badly damaged. The tire sealant
cannot repair the tire in this instance.
The braking and driving characteristics may be
greatly impaired.Do not continue driving.Consult a quali"Ned specialist workshop.
