Ifat ire pressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the fillerh ose from the valve of the
faulty tire.
Note that tire sealant may escape when you
unscrew the fillerh ose.
XUSA only:Stow the tire sealant bottle and the
tire inflation 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,t he tire is too
badlyd amaged. 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.
iUSA only: In cases such as the one men-
tioned above,c ontact an authorized
Mercedes-Benz Center. Or call
1-800-FOR-MERCedes (in the USA) or
1-800-387-0100 (in Canada).
XUSA only: Correct the tire pressure if it is still
at least 130 kPa (1.3 bar/19 psi). See the Tire
and Loading Information placard on the driv-
er's side B-pillarort he tire pressure table in
the fuel fillerf lap for values.
XTo increase the tire pressure: switch on the
tire inflation compressor.
XTo reduce the tire pressure: depresspres-
sure release button :next to pressure
gauge ;.
XWhen the tire pressure is correct, unscrew the
fillerhose from the valve of the sealed tire.
Note that tire sealant may escape when you
unscrew the fillerh ose.
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-
ing tabs on the yellow cap.
XPullthe tire sealant bottle out of the tire infla-
tion compressor.
The fillerh ose remains attached to the tire
sealant bottle.
XDrive to the nearest qualifieds pecialist work-
shop and have the tire changed there.
XHave the tire sealant bottle and the fillerh ose
replaced as soon as possible at aqualified
specialist workshop.
XHave the tire sealant bottle replaced every
four years at aqualifieds pecialist workshop.

GWARNING
Tires with excessively high pressure can burst
becaus etheya re damaged moree asily by
road debris,p otholes etc.Inaddition, they
also suffer fromi rregular wear, which can
severely impair th ebraking properties and the
driving characteristics. Thereisar isk of an

Avoid tir epressures that are too high in all the
tires, including th espare wheel.
Overinflated tires may:

Checking th etirep ressures
Important safety notes
Observe th enotes on tir epressure
(Ypage 290).
Information on air pressure for th etires on your
vehicle can be found:
Ron th evehicle's Tire and LoadingI nformation

Rin th etirep ressure table in th efuel filler flap
(Ypage 139)
Rin th e"Tire pressure" section
Checking tir epressures manually
To determine and set th ecorrectt irep ressure,
proceed as follows:
XRemovet hevalve cap of th etiret hatistob e
checked.
XPresst hetirep ressure gauge securely onto
th ev alve.
XRead th etirep ressure and compare it to the
recommended value on th eTire and Loading
Information placar dorthetirep ressure table
(
Ypage 290).
XIf th etirep ressure is too low, increase th etire
pressure to th erecommended value.
XIf th etirep ressure is too high, releasea ir. To
do so, pressd own themetal pin in th evalve,
using th etip of apen for example. Then check
th et irep ressure again using th etirep ressure
checker.
XScrew th evalve cap ont othe valve.
XRepeat these steps for th eother tires.

General notes
While th evehicle is in motion, th etirep ressure
loss warning system monitors th eset tir epres-
sure using th erotational speed of th ewheels.
This enables th esystem to detect significant
