or
̈ Press the KEYLESS-GO* start/stop
button (
୴ page 33) on the selector le-
ver once. Do not depress brake pedal.
̈ Press I on electric air pump switch 8.
The electric air pump should now
switch on and inflate the tire.
After five 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 pressure is not attained, turn
off the electric air pump, detach the fill-
er hose from the tire valve, and drive
vehicle back and forth very slowly ap-
proximately 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 contain-
er.
̈ Screw air hose 5 onto tire valve 7.
Inflate the tire again.
̈ After attaining a tire pressure of 26 psi
(1.8 bar), press 0 on electric air pump
switch 8.
The electric air pump should now be
switched off.

If sealant has leaked out, let it dry. You
can then peel it off.
!
Do not operate the electric air pump
longer than eight minutes without in-
terruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning! G
If a tire pressure of 26 psi (1.8 bar) is not at-
tained, 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.
