First, TIREFIT is pumped into the tyre .The
pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tyre inflation com-
pressor during this phase.
X Allow the tyre inflation compressor to run
for five minutes. The tyre should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
! Do not operate the tyre inflation com-
pressor for longer than eight minutes at a
time without a break. It may otherwise
overheat.
The tyre inflation compressor can be oper-
ated again once it has cooled down.
If a pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after five minutes, see
(Y page 283).
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see
(Y page 283).
Tyre pressure of 180 kPa (1.8 bar/
26 psi) is not reached If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved:
X Press the on/off switch on the tyre inflation
compressor to 0.
The tyre inflation compressor is switched
off.
X Unscrew the filler hose from the valve.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again. G
Risk of accident
If after five minutes apressure of 180 kPa
(1 8 bar/26 psi) cannot be achieved, the tyre
is too severely 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.
Tyre pressure of 180 kPa (1.8 bar/
26 psi) is reached X
Press the on/off switch on the tyre inflation
compresso rto0.
The tyre inflation compressor is switched
off.
X Remove the tyre sealant bottle from the
wheel.
! After use, excess TIREFIT may run out of
the filler hose. This may cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Pull away immediately. G
Risk of accident
Do not exceed the maximum speed of
80 km/h.
The "max. 80 km/h" label must be affixed in
the driver's field of vision.
The vehicle's handling characteristics may be
affected.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the tyre inflation compressor. G
Risk of accident
If the tyre pressure is less than 130 kPa
(1.3 bar/20 psi), the tyre is too severely dam-
aged. 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 aMercedes-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. Flat tyre

X
Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/20 psi) (for the values,
see the fuel fille rflap).
X To increase the tyre pressure: switch on
the tyre inflation compressor. X
To reduce the tyre pressure: press pres-
sure release button Enext to pressure
gauge F.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Drive to the nearest workshop and have the
tyre changed there.
X Have the tyre sealant bottle replaced as
soon as possible at a qualified specialist
workshop, e.g. at a Mercedes-Ben zService
Centre. H
Environmental note
Have the used tyre sealant bottle disposed of
professionally, e.g. at aMercedes-Benz
Service Centre.
X Have the tyre sealant bottle replaced every
four years at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre. Changing
awheel and fitting the spare

Preparing the vehicle G
Risk of accident
The wheel and tyre size of the emergency
spare wheel/spare wheel may diffe rto that of
the damaged wheel. When using an emer-
gency spare wheel/spare wheel the handling
characteristics of the vehicle may change.
Adapt your style of driving accordingly.
Never operate the vehicle with more than one
emergency spare wheel/spare wheel that dif-
fers in size.
Only use an emergency spare wheel/spare
wheel of a differing size briefly and do not
switch off ESP ®
.
When using an emergency spare wheel you
must not exceed the maximum speed of
80 km/h. G
Risk of accident
Have the emergency spare wheel/spare
wheel replaced with a new wheel as soon as
possible at 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 pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
i Vehicles without an emergency spare
wheel/spare wheel are not equipped with
a tyre-change tool kit at the factory. For
more information on which tools are
required to perform a wheel change on your
vehicle, e.g. wheel chock, centring pin or
wheel wrench, consult a Mercedes-Benz
Service Centre. 284
