X Press on and off switch 0085on the tire inflation
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.
X Let the tire inflation compressor run for a
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 at tained after five minutes, see "Tire pres-
sure reached" (Y page 245).
If a tire pressure of 200 kPa (2.0 bar/29 psi) has not been attained after five minutes, see "Tire
pressure not reached" (Y page 244).
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:
X Switch off the tire inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tire.
Note that tire sealant may escape when you
unscrew the filler hose.
X Very slowly drive forwards or reverse approx-
imately 30 ft (10 m).
X Pump up the tire again.
After a maximum of ten minutes, the tire pres-
sure must be at least 200 kPa (2.0 bar/
29 psi). G
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. 244

It may take up to ten minutes for a malfunction of the tire pressure monitor to be indicated. A
malfunction will be indicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after a few minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gauge. The
tire pressures shown by the on-board computer refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a
pressure gauge are higher than those shown by the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interference from radio transmit-
ting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle.
