Tyres and wheels
178 MOExtended run-flat system*
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in combination with the tyre pressure
loss warning system and only on wheels spe-
cifically tested and approved by Mercedes-
Benz.
i Vehicles with MOExtended run-flat sys-
tem are not equipped with the TIREFIT
kit* 24
.
Therefore, it is recommended that you
equip your vehicle additionally with the
TIREFIT kit* when fitting tyres that do not
feature run-flat properties, e.g. winter
tyres.
i A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
You will find notes on driving with a flat tyre
in the "Practical advice" section
(Y page 262). Tyr
e tread G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4 mm or less as they will
no longer provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the
tread depth and the condition of the
tread across the entire width of all tyres.
If necessary, turn the steering wheel so
that you can see the tyre tread more eas-
ily.
Otherwise, you could lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
i You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel filler flap.
The valid value for the spare wheel* is sta-
ted on the spare wheel and in the technical
data section. G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’s
driving safety, which could lead you to
cause an accident. Therefore, you should
regularly check the pressure of all your
tyres (including the spare tyre *), particu-
larly prior to long trips, and correct the
pressure as necessary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. G
Risk of accident
Should the tyre pressure drop repeatedly:

Risk of injury
TIREFIT must not come into contact with
your skin, eyes or clothing. R
If TIREFIT comes into contact with your
eyes or skin, immediately rinse thor-
oughly with clean water.
R Change out of clothing which has come
into contact with TIREFIT immediately.
R If an allergic reaction occurs, consult a
doctor immediately.
Keep TIREFIT away from children.
R If TIREFIT is swallowed, immediately
rinse your mouth out thoroughly with
water and drink plenty of water.
R Do not induce vomiting. Consult a doctor
immediately.
R Do not inhale TIREFIT fumes.
i If TIREFIT leaks out, allow it to dry. It can
then be removed like a layer of film.
If you get TIREFIT on your clothing, have it
cleaned as soon as possible with perchloro-
ethylene. G
Risk of injury
Comply with the manufacturer's safety
instructions shown on the sticker on the
electric air pump. i
Your vehicle may be equipped with one of
two different air pumps. Version 1 can be
identified by the flap, behind which the
hose with the pressure gauge and cable are
located; version 2 has a pressure gauge
integrated in the electric air pump.

i First, TIREFIT is pumped into the tyre. The
pressure can briefly rise to around 5 bar. Do not switch off the electric pump dur-
ing this phase.
X Let the electric pump run for five minutes.
The tyre should then have a pressure of at
least 1.8 bar.
! Do not operate the electric air pump for
longer than eight minutes at a time without
a break. Otherwise, it may overheat.
The air pump can be operated again once
it has cooled down.
If a pressure of 1.8 bar is not reached after
five minutes:
X Switch off and disconnect the electric air
pump and drive the vehicle forwards or
backwards approximately 10 m.
This distributes the TIREFIT more evenly.
X Remove TIREFIT sealant filler bottle 1
from the electric pump.
X Pump up the tyre again. G
Risk of accident
If a pressure of 1.8 bar is not achieved after
five minutes, the tyre is too badly damaged.

282 Tyres and wheels
Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres which
have been approved specifically for your
vehicle by Mercedes-Benz. These tyres are
specially adapted for use with the control
systems, such as ABS or ESP ®
, and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Exten-
ded* (with run-flat characteristics)
If you use other tyres, Mercedes-Benz can-
not accept any responsibility for damage
which may occur. Information about tyres can be obtained from any Mercedes-Benz
Service Centre.
i Vehicles with MOExtended run-flat sys-
tem are not equipped with the TIREFIT
kit* 35
.
Therefore, it is recommended that you
additionally equip your vehicle with the
TIREFIT kit* when fitting tyres that do not
feature run-flat properties, e.g. winter
tyres.
i A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
! If you fit tyres other than those tested and
recommended by Mercedes-Benz, charac- teristics such as handling, noise levels and
fuel consumption, etc. may be adversely
affected. In addition, when driving with a
load, tyre dimensional variations could
cause the tyres to come into contact with
the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre.
You will find a table of tyre pressures on the
inside of your vehicle's fuel filler flap. You
will find further information about tyre pres-
sures in the "Operation" section
(Y page 178).
