(Y page 316).
X Turn the key to position 1in the ignition lock
(Y page 145).
X Press on and off switch ?on the tyre inflation
compressor to ON.
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 ten minutes. The tyre should
then have attained apressure of at least
200 kPa (2.0 bar/29 psi).
If ap ressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes, see "Tyre pres- sure reached" (Y page 340).
If at yre pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes, see "Tyre
pressure not reached" (Y page 340).
If tyre sealant leaks out, make sure you clean the
affected area as quickly as possible.Itisp ref-
erable to use clear water.
If you get tyre sealant on your clothing, have it
cleaned as soon as possible with perchloroethy- lene.
Tyre pressure not reached If
at yre pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten 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 amaximum of ten minutes, the tyre
pressure must be at least 200 kPa (2.0 bar/
29 psi). G
WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged.T he tyre sealant cannot repair the tyre in this instance. Damaged tyres and
atyre
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
Tyre pressure reached G
WARNING
At yre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitablef or higher speeds. There is arisk of
accident.
You should therefore adapty our driving style
accordingly and drive carefully.Don ot exceed
the specified maximum speed with atyre that
has been repaired using tyre sealant.
The maximum permissibles peed foratyre
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 easilys een by
the driver.
! 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. H
Environmental note
Have the used tyre sealant bottle disposed of
professionally,e .g. ataqualified specialist
workshop.
If at yre pressure of 200 kPa (2.0 bar/29 psi) has
been attained 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 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). 340

WARNING
If the required tyre pressure is not reached
after driving for ashort period, the tyre is too
badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damaged tyres and atyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
i In yourv
ehicle, you willf indasticker 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 tyre pres-
sure table on 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 pres-
sure release button :next to pressure
gauge ;.
X When the tyre pressure is correct, unscrew
the filler hose from the valve of the sealed
tyre.

requires specialist knowledge and the use of
special tools. Therefore, alwaysh ave work on
the battery carrie dout at aqualified specialist
workshop. G
WARNING
Work carrie dout incorrectly on the battery
can lead, for example, to ashort circui tand
thus damage the vehicl eelectronics. This can
leadtof unction restrictions applying to
safety-relevant systems ,e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the

tures. There is arisk of an accident.
Turn on ESP ®
and adapt your driving style
accordingly. When the outside temperature
falls below 10 †, use M+S tyres.
i Different driving styles may lead to higher
levels of tyre wear, meanin gthe tyres may
wear down to the minimum tyre tread depth
after less mileage. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As aresult, you could lose control of
your vehicle. There is arisk of accident.
Check the tyres regularly for signs of damage and replace any damaged tyres immediately.
Check wheels and tyres for damage at least
onc eam onth. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause aloss 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 chec kthe tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 354).Ifnecessary, turn the
fron twheels to full lock in order to inspec tthe
inne rside of the tyre surface.
All wheels must have avalve cap to protect the
valve against dirt and moisture. Do not fit any-
thin gontot he valve other than the standard
valve cap or other valve caps approved for your vehicle by Mercedes-Benz.Don ot fit any other
valve caps or systems ,e.g. tyre pressure moni-
torin gsystems.
Regularly chec kthe pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 356).
Observe the notes on the emergency spare
wheel (Y page 367). The servic
elife of tyres depends on various fac-
tors ,includin gthe following:
R driving style
R tyre pressure
R mileage Notes on the tyr
etread G
WARNING
Insufficien ttyre 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 arisk of accident.
If the tyre pressure is too high or too low, tyres may exhibit differen tlevels of wear at differ-
ent location sonthe tyre tread. Thus, you
should regularly chec kthe tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3mm
R M+S tyres: 4mm
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 ar isk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load ratin gand speed ratin grequired for
your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ment scan stipulate aspecific 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 354

type or make in the even tofaflat tyre.
Observe the "MOExtended tyre s(tyre swith
run-flat characteristics)" section
(Y page 337).
R Only fit tyre softhe correc tsize ont othe
wheels.
R Run in new tyre satmoderate speeds for the
firs t100 km. They only reach their full per-
formanc eafter this distance.
R Do not drive with tyre swhich have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aquaplan-
ing).
R Replace the tyre safter six years at the latest,
regardless of wear.
Observe the notes on the emergenc yspare
wheel (Y page 367). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyre s(tyre swith run-flat char-
acteristics), you can continue to drive your vehi-
cle even if there is atotal loss of pressure in one
or more tyres.
MOExtended tyre smay only be used in conjunc-
tion with an activate dtyre pressure loss warning
system or with an activate dtyre pressure mon-
itor and on wheels specifically tested by
Mercedes-Benz.
Notes on drivin gwith MOExtended tyre swith a
flat tyre (Y page 337).
Vehicles with MOExtended tyre sare not equip-
ped with aTIREFIT kit at the factory. It is there-
for erecommended that you additionally equip
your vehicle with aTIREFIT kit if you fit tyre sthat
do not feature run-flat characteristics, e.g. win-
ter tyres. ATIREFIT kit can be obtained fro ma
qualified specialist workshop. Winter operation
General notes
