X
Press on/off switch =on the electric air
pump to I.
The electric air pump is switched on. The
tyre is inflated.
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 :
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.
Do not drive any further. Consult a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. When a tyre pressure of at least 1.8 bar is
reached:
X
Press on/off switch =on the electric air
pump to 0.
The electric air pump is switched off.
X Disconnect the electric air pump and stow
it away.
X Fold up the warning triangle and stow it
away.
X Pull away immediately.
This distributes the TIREFIT more evenly
around the tyre.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the electric air pump. G
Risk of accident
If the tyre pressure is now lower than 1.3 bar,
the tyre is too badly damaged. Do not drive
any further. Consult a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop. X
If the tyre pressure is still at least 1.3 bar,
correct it (see fuel filler flap for values).
To increase the tyre pressure: switch on
the electric air pump. 226 Flat tyrePractical advice

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
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.
! 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 152).
36 The unladen weight includes the driver (68 kg), luggage (7 kg) and all fluids (fuel tank 90% full). Items of
optional equipment increase the unladen weight and reduce the maximum payload. Tyres and wheels
