(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.

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

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

WARNING
If you fit unsuitabl eaccessories onto tyre
valves, the tyre valve smay be overloadeda nd
malfunction, which can caus etyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can alsor esult in tyre pressure loss. There is a
risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
yourv ehicleonto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly ,the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in atyre
blow-out. There is arisk of accident.
R Check the tyre for foreig nobjects.
R Check whethe rthe whee lislosing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact aqualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
The recommende dtyre pressures for various
operating conditions can be found in the tyre
pressure table on the fuel filler flap
(Y page1 67).
Operation with an emergency spare wheel:
information on operation with an emergency
spar ewhee lcan be found in the genera lnotes in
the "Emergency spar ewheel" section
(Y page3 67).
Operation with atrailer: the applicable value
for the rear axle is the maximu mtyre pressure
valu estated in the table insid ethe fuel filler flap.
Additionally, the tyre pressure table may also
state tyre pressures for different loadc ondi-
tions. These are defined in the table as different numbers of passengers and amounts of lug-
gage .The actua lnumber of seats may vary ;for
more information, please refer to the vehicle's
registration documents.
If tyre sizes are not specified ,the tyre pressures
stated on the tyre pressure table apply for all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the fol-
lowing tyre pressure information is only vali dfor
that tyre size.
Use asuitable pressure gauge to check the tyre
pressure. The outer appearance of atyre does
not permi tany reliablec onclusion about the tyre
pressure. On vehicles fitted with the electronic
tyre pressure monitor, the tyre pressure can be checked using the on-board computer.
If possible,o nly correct tyre pressures when the
tyres are cold.
The tyres are cold:
R if the vehicl ehas been parked with the tyres
out of direct sunlight for at least three hours
and
R if the vehicl ehas not been drive nfurther than
1.6 km
Depending on the ambient temperature, the
vehicl espee dand the loadont he tyres, the tyre
temperature and thus the tyre pressure changes
by approximatel y10k Pa (0.1 bar/1.5 psi) per
10 †. Take this into account when checking the
pressure of warm tyres. Only correct the tyre
pressure if it is too low for the current operating conditions.
Driving with tyre pressure that is too high or too
low can:
R shorten the service life of the tyres
R caus eincreased tyre damage
R have anegative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are minimu mvalues which offer you good ride com-
fort characteristics.
However, you can alsou se the values given for
higher loads. These are permissible and willn ot
adversely affect the running of the vehicle.

General notes While the vehicle is in motion
,the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in atyre. If the speed of rotation of
aw heel changes as aresult of aloss of pressure,
ac orresponding warning message will appear in
the multifunction display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active

warning system" section (Y page 358).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 356).
The tyre pressure loss warning does not replace the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure loss warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the tyre
is penetrated by aforeign object .Inthe event of
as udden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (corner-
