R ifdriving on,observe thefollowing notes
The driving distance possibleinrun-flat modeis
approximately 50miles (80km) when thevehi-

R vehicle speed
R road condition
R outside temperature
The driving distance possibleinrun-flat mode
may bereduced byextrem edriving condition s
or maneuvers, oritcan beincreased througha
moderate styleofdriving. The
driving distance possibleinrun-flat modeis
counted fromthemoment thetire pressure loss

You must notexceed amaximum speedof
50 mph (80km/h).
When replacing oneorall tires, please observe
the following specifications foryour vehicle's

Vehicles equippedwith MOExt ended tiresare
not equipp edwith aTIREFIT kitatthe factory. It
