WARNING Risk of accident when driving
in eme rgency mode
When driving in emer gency mode, the han‐
dling characteristics are impaired. e.g. when
cornering, when accelerating stronglyand
when braking. #
Do not exceed the permissible maxi‐
mum speed. #
Avoid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road). 438

visible damage. Yo
u can recognise MOExtended tyres bythe
MOExtended marking which appears on the side
wa ll of the tyre.
