compressor to I.
The tire inflation compressor is switched on.
The tire is inflated.
i
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 five minutes. The tire should then
have attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a pressure of 180 kPa (1.8 bar/26 psi) has
been attained after five minutes, see "Tire pres-
sure reached" ( page 343).
Y
If a tire pressure of 180 kPa (1.8 bar/26 psi) has
not been attained after five minutes, see "Tire
pressure not reached" (
If tire sealant has escaped, clean it off affected
areas as quickly as possible. It is preferable to
use clean water.
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 pressure of 180 kPa (1.8 bar/26 psi) has not
been attained after five 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.
Very slowly drive forwards or reverse approx-
X
imately 30 ft (10 m).
Pump up the tire again.
X
After a maximum of five minutes the tire pres-
sure must be at least 180 kPa (1.8 bar/
26 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.
