A flat tyre se verely affects the driving charac‐
te rist ics as well as thesteering and braking
of theve hicle. Ty
res without run-flat characteristics: #
Do not drive on with a flat tyre. #
Chan getheflat tyre immediately with
an emer gency spa rewheel or spare

specialist workshop.
Ty res with run-flat characteristics: #
Obse rveth e information and warning
no tes on MOExtended tyres (run-flat
tyres). In
theeve nt of a flat tyre, thefo llowing options
are available depending on your vehicle's equip‐
ment:
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)
(/ page449).
R Vehicles with a TIREFIT kit: you can repair
th e tyre so that it is possible tocontinue the
jou rney for a short period of time. Todo this,
use the TIREFIT kit (/ page 450).448

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). This applies, in pa
rticular, toa loaded
ve hicle. #
Stop driving in the emer gency mode if
yo u notice:
R banging noise
R vehicle vibration
R smoke which smells like rubber
R continuous ESP ®

The defective tire must be replaced in
eve rycase. Wi
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‐
te m: MOExtended tyres may only be used in
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.
