Flat tire
̈ Screw filler hose a onto tire valve 7.
̈ Close vent screw 9 on pressure
gauge.
̈ Insert electrical plug 4 into vehicle
cigarette lighter socket.
̈ Turn the SmartKey in the starter switch
to position 1 (
୴ page 40).
̈ Press I on electric air pump switch 8.
The electric air pump should now
switch on and inflate the tire.
After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose can become hot during inflation.
Please exercise appropriate caution.
̈ If this tire inflation pressure is not at-
tained, turn off the electric air pump,
detach the filler hose from the tire
valve, and drive vehicle back and forth
very slowly approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.
̈ Unscrew the air pump’s air hose 5
from flange 6 of the TIREFIT
container.
̈ Screw air hose 5 onto tire valve 7.
̈ Inflate the tire again.
̈ After attaining a tire inflation pressure
of 26 psi (1.8 bar), press 0 on electric
air pump switch 8.
The electric air pump should now be
switched off.
̈ Turn the SmartKey in the starter switch
to position 0 (
୴ page 40).
̈ Detach the electric air pump.
The air hose may still be hot. Please
exercise appropriate caution.
!
Do not operate the electric air pump longer
than 8 minutes without interruption. Otherwise it
may overheat.
You may operate the air pump again after it has
cooled off.
Warning! G
If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, the tire is too severely
damaged for TIREFIT to provide a reliable
tire repair.
In this case, TIREFIT cannot properly seal
the tire.
Do not drive the vehicle.
Contact the nearest Mercedes-Benz Center
or call Roadside Assistance.
