Preparing the vehicle
Your vehicle may be equipped with:
R a TIREFIT kit
R an emergency spare wheel
R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 324)
i Vehicle preparation is not necessary on
vehicles with MOExtended tyres.
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
properties, e.g. winter tyres. A TIREFIT kit
can be obtained from a Mercedes-Benz
Service Centre.
X Stop the vehicle as far away as possible
from traffic on solid ,non-slippery and level
ground.
X Switch on the hazard warning lamps.
X Firmly depress the parking brake.
X Bring the front wheels into the straight-
ahead position.
X Vehicles with manual transmission:
engage first or reverse gear.
X Vehicles with automatic transmission:
move the selector lever to P.
X Switch off the engine. 316

R
If TIREFIT is swallowed, immediately rinse
yourm outh out thoroughly 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.
Your vehicle is provided with one of two dif-
ferent TIREFIT kits:
R Version 1: the tyre inflation compressor
and the tyre filler bottle both have their own
fixed hoses.
R Version 2: the tyre inflation compressor
and the tyre filler bottle do not come with
a fixed hose. This is in the housing of the
tyre inflation compressor.
TIREFIT kit version 1 X
Pull plug ?with the cable and hose Aout
of the housing.
X Screw hose Aonto flange Bof tyre seal-
ant bottle :.
X Insert tyre sealant bottle :head down-
wards into recess ;of the tyre inflation
compressor. X
Remove the cap from valve Con the faulty
tyre.
X Screw filler hose Donto valve C.
X Insert plug ?into the cigarette lighter
socket (Y page 291) or into a 12 V socket
in your vehicle (Y page 291).
X Turn the key to position 1(Y page 137) in
the ignition lock.
X Press on/offs witch=on the tyre inflation
compressor to I.
The tyre inflatio ncompressor is switched
on. The tyre is inflated.
i 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 six 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 320).
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see
(Y page 319). 318

low cap Aof the tyre sealant bottle :into
the mounting of the tyre inflation compres-
sor ;, until the cap engages.
X Remove filler hose Band plug =from the
bottom section of the tyre inflation com-
pressor housing.
X Slide the yellow filler hose connector into
the mounting on yellow cap Aof tyre seal-
ant bottle :until the plug engages.
Make sure that both teeth engage. X
Remove the cap from valve Con the faulty
tyre.
X Screw filler hose Donto valve.
X Insert plug =into the socket of the ciga-
rette lighter (Y page 291) or into a 12 V
power socket in your vehicle (Y page 291).
X Turn the key to position 1(Y page 137) in
the ignition lock. X
Press on/off switch ?on the tyre inflation
compressor to ON.
The tyre inflation compressor is switched
on. The tyre is inflated.
i 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

The tyre inflation compressor can be oper-
ated again once it has cooled down.
If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has been achieved, see
(Y page 320).
If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved, see
(Y page 319).
Tyre pressure of at least 180 kPa
(1.8 bar/26 psi) not reached If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved:
X
Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again. G
WARNING
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 Flat tyre

the work required. Mercedes-Benz recom-
mends tha tyou 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
Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
! 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
WARNING
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
WARNING
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. X
Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/20 psi) (for the values,
see the fuel filler flap).
X To increase the tyre pressure: switch on
the tyre inflation compressor. Example: TIREFIT kit, version 2
X
To reduce the tyre pressure: press pres-
sure release button :next to pressure
gauge ;.
X TIREFIT kit version 1: take the tyre seal-
ant bottle out of the tyre inflation compres-
sor recess.
X TIREFIT kit version 1: unscrew the hose
from the tyre inflation compressor to the
flange of the tyre sealant bottle. TIREFIT kit version 2
X
TIREFIT kit version 2: to remove the tyre
sealant bottle from the tyre inflation com-
pressor, push the locking mechanisms on
the yellow cap together.
X TIREFIT kit version 2: pull the tyre sealant
bottle out of the tyre inflation compressor. 320
