Ryou MOExtended run-flat system The MOExtended run-flat system allows you to drive on even if there is a complete loss of pressure in one or more tires. The MOExtended run-flat system may only be used in conjunction with the activated tire pressure loss warning system or with the activated tire pressure monitor. The maximum permissible distance which can be driven in run-flat mode depends on the cargo in the vehicle. You can drive 50 miles (80 km) if the vehicle is partially laden and 18 miles (30 km) if it is fully laden. The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tire pressure loss warning appears in the multifunction display.

This is particularly the case when the vehicle is heavily laden. The maximum permissible distance that can be driven in run-flat mode depends to a large extent on the loads placed on the vehicle. It can be shorter due to high speeds, a heavy cargo, sudden changes in direction, the road surface condition, outside temperature, etc., or further if you drive carefully and conservatively.
