MOExtended tyres (tyres with run-flat
characteristics)
General notes
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres. The affected
tyre must not show any clearly visible dam-
age.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the
tyre wall. You will find this marking next to the
tyre size designation, the load-bearing capa-
city and the speed index.
MOExtended tyres may only be used in con-
junction with an activated tyre pressure loss
warning system or tyre pressure monitor.
If a pressure loss warning message
appears in the multifunction display:
observe the instructions in the display mes-
R
sages ( page 367)
Y
check the tyre for damage
R
if driving on, observe the following notes
R
The driving distance possible in run-flat mode
is approximately 80 km when the vehicle is
partially laden and approximately 30 km
when the vehicle is fully laden.
In addition to the vehicle load, the driving dis-
tance possible depends upon:
vehicle speed
R
road condition
R
outside temperature
R
The driving distance possible in run-flat mode
may be reduced by extreme driving condi-
tions/manoeuvres, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tyre pressure
loss warning appears in the multifunction dis-
play.
You must not exceed a maximum speed of
80 km/h.
When replacing one or all tyres, observe the
following specifications for your vehicle's
tyres:
size
R
the type and
R
the "MOExtended" mark
R
If a tyre has gone flat and cannot be replaced
with an MOExtended tyre, a standard tyre
may be used as a temporary measure. Make
sure that you use the proper size and type
(summer or winter tyre).
Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is
therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you fit
tyres that do not feature run-flat characteris-
tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop.
Important safety notes
G WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving manoeu-
vres, and driving over obstacles (kerbs, pot-
holes, off-road). This applies in particular to a
laden vehicle.
Stop driving in emergency mode if:
you hear banging noises.
R
the vehicle starts to shake.
R
you see smoke and smell rubber.
