Make sure that the pressure release
screw on pressure gauge 9 is fully
closed.
Screw filler hose a onto valve 7.
Insert connector 4 into the cigarette
lighter socket ( page 379) or into a
12 V socket* in the vehicle
( page 380).
Turn the key to position 1 in the igni-
tion lock ( page 257).
Press I on electric air pump switch 8.
The electric air pump is switched on.
The tyre is pumped up. After five min-
utes, the tyre should have a pressure of
at least 1.8 bar.
!
Do not operate the electric air pump for
longer than 6 minutes without a break, otherwise
it may overheat.
The air pump can be used again once it has
cooled down.
If a maximum tyre pressure of 1.8 bar is
not achieved:
Switch off and remove the electric air
pump.
Drive the vehicle approximately 10 m
forwards or backwards.
This distributes the TIREFIT sealant
more evenly.
Remove the filler bottle from the elec-
tric air pump.
Pump up the tyre again.

Risk of accident
If a pressure of 1.8 bar still cannot be
achieved after five minutes, the tyre is too
badly damaged.
Do not drive any further. Consult a qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-re-
lated systems must be carried out at a
qualified specialist workshop.
When the tyre pressure of 1.8 bar has been
achieved:
Press 0 on the electric air pump switch.
Remove the electric air pump.
Pull away immediately.
