Flat tire
Preparing the vehicle
Your vehicle may be equipped with:
R
tires with run-flat characteristics
(MOExtended tires) (Y page 278)
Vehicle preparation is not necessary on
vehicles with MOExtended tires.
R
a TIREFIT kit (Y page 277)
Vehicles with the Mercedes-Benz emer-
gency call system: in the event of a flat tire,
you can contact the Mercedes-Benz emer-
gency call system customer center.
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addition-
ally equip your vehicle with a TIREFIT kit if you
mount tires that do not feature run-flat charac-
teristics, e.g. winter tires. A TIREFIT kit may be
obtained from a qualified specialist workshop.

MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive your
vehicle even if there is a total loss of pressure
in one or more tires. The affected tire must not
show any clearly visible damage.
You can recognize an MOExtended tire by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index
(Y page 307).
MOExtended tires may only be used in con-
junction with an active tire pressure monitor.
