Preparing the vehicle
Your vehicle may be equipped with: R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 298)
Vehicle preparation is not necessary on vehi- cles with MOExtended tyres.
R a TIREFIT kit (Y page 297)
R an emergency spare wheel (certain countries
only) (Y page 325)
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop.
Information on changing and fitting a wheel
(Y page 320).
X Stop the vehicle as far away as possible from
traffic on solid, non-slippery and level ground.
X Switch on the hazard warning lamps.
X Safeguard the vehicle against rolling away
(Y page 150).
X If possible, bring the front wheels into the
straight-ahead position.
X Switch off the engine.
X Remove the key from the ignition lock.
or, on vehicles with KEYLESS‑GO:
X Open the driver's door.
The on-board electronics now have status 0.
This is the same as the key having been
removed.
X Remove the Start/Stop button from the igni-
tion lock (Y page 132).
X Make sure that the passengers are not endan-
gered as they do so. Make sure that no one is
near the danger area while a wheel is being
changed. Anyone who is not directly assisting in the wheel change should, for example,
stand behind the barrier.
X Get out of the vehicle. Pay attention to traffic
conditions when doing so.
X Close the driver's door.
X Place the warning triangle at a suitable dis-
tance (Y page 296). Observe legal require-
ments. MOExtended tyres (tyres with run-flat
characteristics)
General notes With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi- cle even if there is a total loss of pressure in one
or more tyres. The affected tyre must not show
any clearly visible damage.
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 capacity and
the speed index.
MOExtended tyres may only be used in conjunc- tion with an activated tyre pressure loss warning
system or tyre pressure monitor.
If a pressure loss warning message appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 239)
R check the tyre for damage
R if driving on, observe the following notes
The driving distance possible in run-flat mode is
approximately 80 km when the vehicle is parti-
ally 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 vehicle speed
R road condition
R outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions/
manoeuvres, or it can be increased through a
moderate style of driving.
The driving distance possible 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.
When replacing one or all tyres, observe the fol-
lowing specifications for your vehicle's tyres:
R size
R the type and
R the "MOExtended" mark
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 298
Flat tyreBreakdown assistance

that you use the proper size and type (summer
or winter tyre).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained 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 †. 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 compres-
sor 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 instruc-
tions on the sticker on the tyre inflation com-
pressor. Flat tyre

Using the TIREFIT kit
X
Do not remove any foreign objects which have
penetrated the tyre, e.g. screws or nails.
X Remove the tyre sealant bottle, the accom-
panying TIREFIT sticker and the tyre inflation
compressor from the stowage space under
the boot floor (Y page 297).
X Affix part :of the TIREFIT sticker to the
instrument cluster within the driver's field of
vision.
X Affix part ;of the TIREFIT sticker near the
valve on the wheel with the defective tyre. X
Pull plug ?with the cable and hose Aout of
the tyre inflation compressor housing.
X Screw hose Aonto flange Bof tyre sealant
bottle :.
X Place tyre sealant bottle :head downwards
into recess ;of the tyre inflation compres-
sor. X
Remove the cap from valve Con the faulty
tyre.
X Screw filler hose Donto valve C.
X Insert plug ?into a 12 V socket (Y page 274)
in your vehicle.
X Turn the key to position 1in the ignition lock
(Y page 132).
X Press on and off switch =on the tyre inflation
compressor to I.
The tyre inflation compressor is switched on.
The tyre is inflated.
First, tyre sealant is pumped into the tyre. The pressure may briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tyre inflation com-
pressor during this phase.
X Let the tyre inflation compressor run for a
maximum of five minutes. The tyre should
then have attained a pressure of at least
180 kPa (1.8 bar/26 psi).
If a pressure of 180 kPa (1.8 bar/26 psi) has
been attained after five minutes, see "Tyre pres-
sure reached" (Y page 301).
If a tyre pressure of 180 kPa (1.8 bar/26 psi) has not been attained after five minutes, see "Tyre
pressure not reached" (Y page 301).
If tyre sealant leaks out, make sure you clean the
affected area as quickly as possible. It is pref-
erable to use clear water.
If you get tyre sealant on your clothing, have it
cleaned as soon as possible with perchloroethy- lene. 300
Flat tyreBreakdown assistance

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.
Please note that tyre sealant may leak out
when unscrewing the filler hose.
X Very slowly drive forwards or reverse approx-
imately 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.
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 instru-
ment cluster where it will be easily seen by the
driver.
! After use, excess tyre sealant may run out of
the filler hose. This could cause stains.
Therefore, place the tyre sealant bottle with
filler hose in the plastic bag which is con-
tained the TIREFIT kit. 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 attained after five 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 inflation
compressor and the warning triangle.
X Pull away immediately.
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 ba r/19 psi). See the tyre pres-
sure table on the fuel filler flap for values.
X To increase the tyre pressure: switch on
the tyre inflation compressor. Flat tyre
301Breakdown assistance Z

Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
Check wheels and tyres for damage at least
once a month. Check wheels and tyres 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 the 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 314). 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 any-
thing onto the valve other than the standard
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 pressure moni-
toring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 316).
Observe the notes on the emergency spare
wheel (Y page 325).
The service life of tyres depends on various fac- tors, including the following:
R driving style
R tyre pressure
R mileage 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
tyre load rating and speed rating required for your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ments 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 298).
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 per-
formance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly 314
OperationWheels and tyres

reduces the traction on wet roads (aquaplan-
ing).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 325). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi- cle even if there is a total loss of pressure in one
or more tyres.
MOExtended tyres may only be used in conjunc- tion with an activated tyre pressure loss warning system or with an activated tyre pressure mon-
itor and on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tyres with a
flat tyre (Y page 298).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist 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 321). Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle 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. 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 damageand replace any damaged tyres immediately. 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 types of tyre are identified
by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tyres will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyres that have a lower maximum
permissible speed than that of the maximum
design speed of the vehicle, affix a correspond- ing warning label in the driver's field of vision.
This can be obtained at a qualified specialist
workshop.
Under these circumstances, you should also
restrict the maximum design speed of the vehi- cle using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 161). Winter operation
