Vehicles with MOExtended tyres are not equip-

fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that
do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop.

MOExtended tyres (tyres with run-flat
characteristics)
General notes
With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one
or more tyres. The affected tyre must not show
any clearly visible damage.
You can recognise MOExtended tyres by the
"MOExtended" mark that appears on the tyre
sidewall. You will find this mark next to the tyre
size designation, the load-bearing capacity and
the speed index.
MOExtended tyres may be used only in conjunc-
tion 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 256)
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 parti-
ally laden and approximately 30 km when the
vehicle is fully laden.
In addition to the vehicle load, the driving dis-
tance possible in run-flat mode depends on the:
vehicle speed
R
road condition
R
outside temperature
R
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions/
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 on the multifunction display.
You must not exceed a maximum speed of
80 km/h.
When replacing one or all tyres, observe the fol-
lowing specifications for your vehicle's tyres:

R
type and
R
the "MOExtended" marking

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
