dling characteristics are impaired, e.g. when
cornering, when accelerating stronglyand
when braking.
#Do not exceed the specified maximum
speed.
#Av oid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road).
This applies, in part icular,toa loaded
ve hicle.
#Stop driving in the emer gency mode if

ist workshop with rega rd totheir fur ther
use.
#The defective tire must be replaced in
eve rycase.
With MOExtended tires (run-flat tires), you can
continue todrive your vehicle even if there is a
tot al loss of pressure in one or more tires. How‐
eve r,th e tire af fected must not show any clearly
visible damage.
Yo u can recognize MOExtended tires bythe
MOExtended marking which appears onthe side
wa ll of the tire.
