MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat char-
acteristics) ,you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires. The affected tire must not show
any clearly visible damage.
You can recognize aMOExtended tire by the
MOExtended marking which appears on the
sidewal lofthe tire. You wil lfind this marking
next to the tire size designation, the load-bear-
ing capacity and the speedi ndex (
Ypage302).
MOExtended tires may be used only in conjunc-
tion with an activated tire pressure loss warning

Breakdown assistance

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.
