X
Vehicles with the AIRMATIC package*
or Off-Road Pro engineering package*:
remove the Start/Stop button from the
ignition lock.
X Get out of the vehicle.
X Close the driver’s door.
X Place the warning triangle (Y page 208) at
a suitable distance. Observe legal require-
ments.
i Only operate the electric air pump using
the socket in the footwell of the second row
of seats (Y page 163), even if the ignition
is turned off.
An emergency cut-off ensures that the on-
board voltage does not drop too low. If the
on-board voltage is too low, power to the
sockets is automatically cut-off. This
ensures that there is sufficient power to
start the engine. Using the TIREFIT kit
You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread.
You can use TIREFIT at outside temperatures
down to -20 †. G
Risk of accident
In the following cases your safety is especially
endangered, as tyre sealant is insufficient if:
R there are cuts or punctures in the tyre
greater than 4 mm.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on a flat tyre.
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 pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop. X
Do not remove any foreign objects which
have penetrated the tyre, e.g. screws or
nails.
X Remove the TIREFIT kit, the accompanying
"max. 80 km/h" sticker and the electric air
pump from the stowage well underneath
the luggage compartment floor
(Y page 209). X
Affix part :of the sticker within the driv-
er's field of vision.
X Affix part ;of the sticker near the valve
on the wheel with the defective tyre. G
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 thoroughly
with clean water.
R Change out of clothing which has come into
contact with TIREFIT immediately.
R If an allergic reaction occurs, consult a doc-
tor immediately.
Keep TIREFIT away from children.
R If TIREFIT is swallowed, immediately rinse
your mouth out thoroughly and drink plenty
of water.
R Do not induce vomiting. Consult a doctor
immediately.
R Do not inhale TIREFIT fumes. Flat tyre

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 elec-
tric air pump.
Your vehicle may be equipped with one of two
different air pumps. Version 1 can be identi-
fied by the flap, behind which the hose with
the pressure gauge and cable are located;
version 2 has a pressure release button in the
air hose of the electric air pump.
Version 1 X
Open flap ;on the electric air pump.
X Pull connector Awith cable and air pump
hose Bout of the housing.
X Screw air pump hose Bonto flange Cof
TIREFIT sealant filler bottle :.
X Place TIREFIT sealant filler bottle :head
downwards into recess =of the electric
air pump. X
Remove the cap from valve Eon the faulty
tyre. X
Make sure pressure release screw Fon
pressure gauge Gis fully closed.
X Screw filler hose Donto valve E.
X Insert connector Ainto the socket in the
footwell of the second row of seats
(Y page 163).
! The socket/cigarette lighter* in the front
centre console is not designed for operat-
ing the electric air pump.
X Vehicles without KEYLESS GO*: turn the
key to position 2(Y page 63) in the ignition

Environmental note
Have the used TIREFIT kit disposed of profes-
sionally, e.g. at a Mercedes-Benz Service
Centre.
X Have the TIREFIT kit replaced every four
years at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.

X Vehicles with KEYLESS GO*: press the
Start/Stop button twice (position
2 (Y page 63)).
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. It may otherwise 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. 266
