If tir ep ressure of 20 0k Pa (2.0 ba r/ 29 psi )h as
bee na chieved after am aximu mp eriod of ten
minutes: X
Switch off the tire inflation compressor. X
Unscrew the filler hose from the valve of the
faulty tire. X
Stow the tire sealant bottle and the tire infla-
tion compressor. X
Pull away immediately .X
Stop 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).
G WARNING
If the required tire pressure is not reached
after driving for as hort 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 ar isk of accident.
Do not continue driving. Contact aq ualified
specialist workshop.
i In cases such as the one mentioned above,
contact an authorized Mercedes-Benz Cen-
ter. Or call 1-800-FOR-MERCede s( in the

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