Driving in emergency mode impairs the han-

dling characteristics of the vehicle.

With MOExtended tyres (run-ﬂat tyres), you can

continue to drive your vehicle even if there is a

total loss of pressure in one or more tyres. How-

ever, the tyre aﬀected must not show any clearly

visible damage.

You can recognise MOExtended tyres by the

MOExtended marking which appears on the side

wall of the tyre.

Vehicles with tyre pressure monitoring system:

MOExtended tyres may only be used in conjunc-

tion with an activated tyre pressure monitoring

system.

Do not exceed the permissible maximum

The driving distance possible in emergency mode

may vary depending on the driving style. Observe

the maximum permissible speed of 80 km/h.

If a tyre has gone ﬂat and cannot be replaced with

an MOExtended tyre, you can use a standard tyre

as a temporary measure.

Do not switch oﬀ the tyre inﬂation compressor

during this phase!

Let the tyre inﬂation compressor run for a

maximum of ten minutes.

The tyre should then have attained a tyre pres-

sure of at least 200 kPa (2.0 bar/29 psi).

If tyre sealant leaks out, make sure you clean the

aﬀected area as quickly as possible. It is prefera-

ble to use clean water.

If you get tyre sealant on your clothing, have it

cleaned as soon as possible with perchloroethy-

lene.

Remove the valve cap from valve 7 on the

faulty tyre.

Screw ﬁlling hose 8 onto valve 7.

Insert plug 4 into a 12‑V‑socket in your vehi-

cle.

Switch on the vehicle.

Press on and oﬀ switch 3 on the tyre inﬂa-

tion compressor.

If, aꢀer ten minutes, a tyre pressure of 200 kPa

(2.0 bar/29 psi) has not been attained:

Pull plug 4 with the cable and hose 5 out

of the tyre inﬂation compressor housing.

Push the plug of hose 5 into ﬂange 6 of

tyre sealant bottle 1 until the plug engages.

Place tyre sealant bottle 1 head downwards

into recess 2 of the tyre inﬂation compres-

sor.

Switch oﬀ the tyre inﬂation compressor.

Unscrew the ﬁlling hose from the valve of the

defective tyre.

The tyre inﬂation compressor is switched on.

The tyre is inﬂated. First, tyre sealant is pum-

ped into the tyre. The pressure may brieﬂy rise

to approximately 500 kPa (5 bar/73 psi).

Please note that tyre sealant may leak out when

unscrewing the ﬁlling hose.

Drive forwards or in reverse very slowly for

approximately 10 m.

with a tyre that has been repaired using

tyre sealant.

Have the tyre sealant bottle disposed of

professionally, e.g. at a Mercedes-Benz

Service Centre.

Aꢀer a maximum of ten minutes the tyre pres-

sure must be at least 200 kPa (2.0 bar/

29 psi).

Switch oﬀ the tyre inﬂation compressor.

Unscrew the ﬁlling hose from the valve of the

defective tyre.

WARNING Risk of accident due to the

speciﬁed tyre pressure not being attained

Observe the maximum permissible speed of

80 km/h for a tyre sealed with tyre sealant.

Aﬃx the upper section of the TIREFIT sticker

to the instrument cluster in a location where it

will be easily seen by the driver.

If the speciﬁed tyre pressure is not attained

aꢀer the speciﬁed time, the tyre is too badly

damaged. The tyre sealant cannot repair the

tyre in this instance.

The braking and driving characteristics may be

greatly impaired.

Stow the tyre sealant bottle and the tyre inﬂa-

tion compressor.

Pull away immediately.

Stop driving aꢀer approximately ten minutes

and check the tyre pressure using the tyre

inﬂation compressor.

NOTE Staining from leaking tyre sealant

Do not continue driving.

Consult a qualiﬁed specialist workshop.

The tyre pressure must now be at least

130 kPa (1.3 bar/19 psi).

Aꢀer use, excess tyre sealant may leak out

from the ﬁlling hose.

Therefore, place the ﬁlling hose in the

plastic bag that contained the TIREFIT

kit.

If, aꢀer ten minutes, a tyre pressure of 200 kPa

(2.0 bar/29 psi) has been attained:

WARNING Risk of accident due to the

speciﬁed tyre pressure not being attained

If the speciﬁed tyre pressure is not reached,

the tyre is too badly damaged. The tyre seal-

ant cannot repair the tyre in this instance.

The braking and driving characteristics may be

greatly impaired.

WARNING Risk of accident from driving

with sealed tyres

ENVIRONMENTAL NOTE Environmental

pollution caused by environmentally irre-

sponsible disposal
