306 Breakdown assistance
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if
you mount tires that do not feature run-flat
characteristics, e.g. winter tires. A TIREFIT kit
may be obtained from a qualified specialist
workshop.
Vehicles with a Mercedes-Benz emergency
call system and that are not equipped with a
TIREFIT kit: in the event of a flat tire, contact
the Customer Assistance Center for the
Mercedes-Benz emergency call system .
