If tir epressure of 20 0kPa(2.0 ba r/29 psi )has
beena chieved after amaximu mperiod of ten
minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of the
faulty tire.
XStow the tire sealant bottle and the tire infla- tion compressor.
XPull away immediately.
XStop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for ashort period, 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 arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
iIn cases such as the one mentioned above,
contact an authorized Mercedes-Benz Cen-
ter. Or call 1-800-FOR-MERCedes( in the
USA) or 1-800-387-0100 (in Canada).
XCorrect the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi).S ee the Tire and
Loading Information placard on the driver's

XTo increase the tire pressure: switch on the
tire inflation compressor.
XTo reduce the tire pressure: depress pres-
sure release button :next to pressure

XWhen the tire pressure is correct, unscrew the
filler hose from the valve of the sealed tire.
XScrew the valve cap onto the tire valve of the
sealed tire.
XTo remove the tire sealant bottle from the tire
inflation compressor, press together the lock-
