Notes on MOExtended tyres (run-flat tyres)

WARNING Risk of accident when driving in limp-home mode

Driving in emergency mode impairs the handling characteristics of the vehicle.

Do not exceed the permissible maximum speed of the MOExtended tyres.

Avoid any abrupt steering and driving manoeuvres as well as driving over obstacles (kerbs, pot holes, off-road). This applies, in particular, to a loaded vehicle.

Stop driving in the emergency mode if you notice:

banging noise
vehicle vibration
smoke which smells like rubber
continuous ESP® intervention
cracks in the tyre sidewalls

After driving in emergency mode, have the rims checked by a qualified specialist workshop with regard to their further use.

The defective tyre must be replaced in every case.

With MOExtended tyres (run-flat tyres), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tyres. However, the tyre affected must not show any clearly visible damage.

You can recognise MOExtended tyres by the MOExtended marking which appears on the side wall of the tyre.

Vehicles with tyre pressure loss warning system: MOExtended tyres may only be used in conjunction with an activated tyre pressure loss warning system.

Vehicles with tyre pressure monitoring system: MOExtended tyres may only be used in conjunction with an activated tyre pressure monitoring system.

If a pressure loss warning message appears in the multifunction display, proceed as follows:

Check the tyre for damage.
If driving on, observe the following notes.

Driving distance possible in emergency mode after the pressure loss warning:
Load condition	Driving distance possible in emergency mode
Partially laden	80 km
Fully laden	30 km

The driving distance possible in emergency mode may vary depending on the driving style. Observe the maximum permissible speed of 80 km/h.

If a tyre has gone flat and cannot be replaced with an MOExtended tyre, you can use a standard tyre as a temporary measure.
