Remove filler hose B and connector = from
X
the bottom section of the tire inflation com-
pressor housing ;.
Slide the yellow filler hose connector into the
X
mounting on yellow cap A of tire sealant filler
bottle : until the connector engages.
With the sealing rings in front, slide yellow cap
X
A of tire sealant bottle : into the mounting
of tire inflation compressor ;.
Yellow cap A and both hooks must engage.
Remove the cap from valve C on the faulty
X
tire.
Screw filler hose D onto valve C.
X
Insert plug = into a 12 V socket in your vehi-
X
cle.
Observe the notes on sockets (
Turn the SmartKey to position 1 in the igni-
X
tion lock ( page 114).
Y
Press on and off switch ? on the tire inflation
X
compressor to ON.
The tire inflation compressor is switched on.
The tire is inflated.
First, tire sealant is pumped into the tire. The
pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
Let the tire inflation compressor run for a
X
maximum of ten minutes. The tire should then
have attained a pressure of at least 200 kPa
(2.0 bar/29 psi).
If a pressure of 200 kPa (2.0 bar/29 psi) has
been attained after five minutes, see "Tire pres-
sure reached" ( page 256).
Y
If a tire pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after five minutes, see "Tire
pressure not reached" (
page 233).

If tire sealant has escaped, clean it off affected
areas as quickly as possible. Use plain water if
possible.
If your clothes are soiled with tire sealant, have
them cleaned with perchloroethylene at a dry
cleaner as soon as possible.

Tire pressure not reached

If a tire pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes:
Switch off the tire inflation compressor.
X
Unscrew the filler hose from the valve of the
X
faulty tire.
Note that tire sealant may escape when you
unscrew the filler hose.
USA only: very slowly drive forwards or
X
reverse approximately 30 ft (10 m).
Pump up the tire again.
X
After a maximum of ten minutes, the tire pres-
sure must be at least 200 kPa (2.0 bar/
29 psi).

WARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached
G
WARNING
A tire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tire that
has been repaired using tire sealant.
USA only: The maximum permissible speed for
a tire sealed with tire sealant is 50 mph
(80 km/h). The upper part of the TIREFIT sticker
