X Get out of the vehicle. Pay attention to traf-
fic conditions when doing so.
X Close the driver's door.
X Place the warning triangle a suitable dis-
tance away (Y page 576). Observe legal
requirements. MOExtended tyres (tyres with run-flat
characteristics)
General notes With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres. The affected
tyre must not show any clearly visible dam-
age. 578
Flat tyreBreakdown assistance

You can recognise MOExtended tyres by the
MOExtended marking which appears on the
tyre wall. You will find this marking next to the
tyre size designation, the load-bearing capa-
city and the speed index.
MOExtended tyres may only be used in con-
junction with an activated tyre pressure loss
warning system or tyre pressure monitor.
If the pressure loss warning message
appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 267).
R check the tyre for damage
R if driving on, observe the following notes
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
laden and approximately 30 km when the
vehicle is fully laden.
In addition to the vehicle load, the driving dis- tance possible depends upon:
R speed
R road condition
R outside temperature
The driving distance possible in run-flat mode may be reduced by extreme driving condi-
tions/manoeuvres, or it can be increased
through a moderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure loss warning
appears in the multifunction display.
You must not exceed a maximum speed of
80 km/h.
i When replacing one or all tyres, make
sure that you use only:
R the tyre size specified for the vehicle and
R tyre(s) marked "MOExtended"
If a tyre has gone flat and cannot be
replaced with an MOExtended tyre, a
standard tyre may be used as a temporary
measure. Make sure that you use the
proper size and type (summer or winter
tyre). i
Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It
is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit is available, for example, from a qualified
specialist workshop.
Important safety notes G
WARNING
When driving in emergency mode, the driving characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving manoeu-
vres, and driving over obstacles (kerbs, pot-
holes, off-road). This applies in particular to a laden vehicle.
Stop driving in emergency mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
faulty tyre must be replaced. TIREFIT kit
Important safety notes TIREFIT is a tyre sealant.
You can use TIREFIT to seal punctures of up to
4 mm, particularly those in the tyre tread. You can use TIREFIT at outside temperatures
down to Ò20 †. Flat tyre
579Breakdown assistance Z

G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis- tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on a flat tyre.
There is a risk of an accident.
Do not drive any further. Contact a qualified
specialist workshop. G
WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tyre sealant away
from children. There is a risk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
R Immediately change out of clothing which
has come into contact with tyre sealant.
R If an allergic reaction occurs, seek medical
attention immediately.
! Do not operate the tyre inflation com-
pressor for longer than eight minutes at a
time without a break. It may otherwise
overheat.
The tyre inflation compressor can be oper-
ated again once it has cooled down.
Comply with the manufacturer’s safety
instructions on the sticker on the tyre infla-
tion compressor. Using the TIREFIT kit

The tyre inflation compressor is switched
on. The tyre is inflated.
i First, tyre sealant is pumped into the tyre.
The pressure may briefly rise to approx-
imately 500 kPa (5.0 bar/73 psi).
Do not switch off the tyre inflation com-
pressor during this phase.
X Let the tyre inflation compressor run for
five minutes. The tyre should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a tyre pressure of 180 kP a(1.8 bar/26 psi)
has been attained after five minutes:
(Y page 581).
If a tyre pressure of 180 kPa (1.8 bar/26 psi)
has not been attained after five minutes:
(Y page 581).
i If the tyre sealant leaks out, allow it to dry.
It can then be removed like a layer of film. If you get tyre sealant on your clothing,
have it cleaned as soon as possible with
perchloroethylene.
Tyre pressure not reached If a pressure of 180 kPa (1.8 bar/26 psi) has
not been attained after five minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
X Very slowly drive forwards or reverse,
approximately 10 m.
X Pump up the tyre again.
After a maximum of five minutes, the tyre
pressure must be at least 180 kPa (1.8 bar/
26 psi). G
WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this instance. Damaged tyres and a tyre pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tyre pressure reached G
WARNING
A tyre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed the specified maximum speed with a tyre that
has been repaired using tyre sealant.
! After use, excess tyre sealant may run out
of the filler hose. This could cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit. Flat tyre

H
Environmental note
Have the used tyre sealant bottle disposed of professionally, e.g. at a qualified specialist
workshop.
If a tyre pressure of 180 kPa (1.8 bar/26 psi) has been achieved after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Pull away immediately .
The maximum speed for a tyre sealed with
tyre sealant is 80 km/h. The upper part of
the TIREFIT sticker must be affixed to the
instrument cluster where it will be easily
seen by the driver.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the tyre inflation compressor.
The tyre pressure must now be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tyre pressure is not reached
after driving for a short period, the tyre is too badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damaged tyres and a tyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
i In your vehicle, you will find a sticker with
the Mercedes-Benz Service24h telephone
number, e.g. on the B-pillar on the driver's
side.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi) (see the fuel filler
flap for values).
X To increase the tyre pressure: switch on
the tyre inflation compressor. X
To reduce the tyre pressure: depress
pressure release button :next to pres-
sure gauge ;.
X When the tyre pressure is correct, unscrew
the filler hose from the valve of the sealed
tyre.
X Screw the valve cap onto the tyre valve of
the sealed tyre.
X Pull the tyre sealant bottle out of the tyre
inflation compressor.
The filler hose stays on the tyre sealant
bottle.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Drive to the nearest qualified specialist
workshop and have the tyre changed there.
X Have the tyre sealant bottle replaced as
soon as possible at a qualified specialist
workshop.
X Have the tyre sealant bottle replaced every
four years at a qualified specialist work-
shop. Battery (vehicle)

damage. Hidden tyre damage could also be
causing the unusual handling characteristics. If you find no signs of damage, have the tyres
and wheels checked at a qualified specialist
workshop.
When parking your vehicle, make sure that
the tyres do not get deformed by the kerb or
other obstacles. If it is necessary to drive over
kerbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
may be damaged. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damage and replace any damaged tyres immediately.
Regularly check the wheels and tyres of your
vehicle for damage at least once a month, as well as after driving off-road or on rough
roads. Damaged wheels can cause a loss of
tyre pressure. Pay particular attention to
damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on tyres
R deformation or severe corrosion on wheels
Regularly check the tyre tread depth and the condition of the tread across the whole width
of the tyre (Y page 597). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tyre surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not fit
anything onto the valve other than the stand-
ard valve cap or other valve caps approved for
your vehicle by Mercedes-Benz. Do not fit any other valve caps or systems, e.g. tyre pres-
sure monitoring systems. Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 600).
Observe the notes on the emergency spare
wheel (Y page 614).
The service life of tyres depends on various
factors, including the following:
R driving style
R tyre pressure
R mileage Important safety notes on the tyre
tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces, the risk of aquaplaning increases, in particularwhere speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the Operation
597Wheels and tyres
Z

tyre load rating and speed rating required for
your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These
requirements can stipulate a specific tyre
type for your vehicle. Furthermore, the use of certain tyre types in certain regions and areas
of operation can be highly beneficial. You can find further information regarding tyres at
specialist tyre retailers, at qualified specialist
workshops or at any Mercedes-Benz Service
Centre.
R Only fit tyres and wheels of the same type
and make.
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics" section
(Y page 578).
R Only fit tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for
the first 100 km. They only reach their full
performance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
R Replace the tyres after six years at the lat-
est, regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 614). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres.
Only use MOExtended tyres in conjunction
with an activated tyre pressure loss warning
system or tyre pressure monitoring system
and only on tyres specifically inspected by
Mercedes ‑Benz. Notes on driving with MOExtended tyres with
a flat tyre (Y page 578).
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It
is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit can be obtained from a qualified spe-
cialist workshop. Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel" section (Y page 605). Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticity and therefore traction and
braking power. Change the tyres on your vehi- cle to M+S tyres. Using summer tyres at very
cold temperatures could cause tears to form, thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres or all-season tyres. Both are marked with
M+S. 598
