R Vehicles with MOExtended tyres: it is pos‐
sible tocontinue the journey for a short
period of time. Make sure you obse rvethe
no tes on MOExtended tyres (run-flat tyres)
(0013 page411).
R Vehicles with a TIREFIT kit: you can repair

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. 0007
Do not exceed the permissible maxi‐
mum speed. 0007
Avoid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road). This applies, in pa

th MOExtended tyres (run-flat tyres), you can
continue todrive your vehicle even if there is a
tot al loss of pressure in one or more tyres. How‐
eve r,th e tyre af fected must not show any clearly
visible damage. Yo
u can recognise MOExtended tyres bythe
MOExtended marking which appears onthe side
wa ll of the tyre.
Ve hicles with tyre pressure loss warning sys‐

conjunction wi than activated tyre pressure loss
wa rning sy stem.
Ve hicles with tyre pressure monitoring sys‐
te m: MOExtended tyres may only be used in
conjunction wi than activated tyre pressure mon‐
itoring sy stem.
If a pressure loss warning message appears in
th e multifunction displa y,proceed as follo ws:
R Check the tyre for dama ge.
