MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive your
vehicle even if there is a total loss of pressure
in one or more tires. The affected tire must not
show any clearly visible damage.
You can recognize an MOExtended tire by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index
(Y page 283).
MOExtended tires may only be used in con-
junction with an active tire pressure loss warn-
ing system or with an active tire pressure mon-
itor.
If a pressure loss warning message
appears in the multifunction display:
R
observe the instructions in the display mes-
sages (Y page 201)
R
check the tire for damage
R
if driving on, observe the following notes
The driving distance possible in run-flat mode
is approximately 50 miles (80 kilometers)
when the vehicle is partially laden and approx-
imately 19 miles (30 kilometers) when the
vehicle is fully laden.
In addition to the vehicle load, the driving dis-
tance possible depends upon:
R
Vehicle speed
R
Road condition
R
Outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, 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 tire pressure
loss warning appears in the multifunction dis-
play.
You must not exceed a maximum design
speed of 50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for your vehicle's
tires:
R
Size
R
Type and
R
The "MOExtended" mark
If a tire has gone flat and cannot be replaced
with an MOExtended tire, a standard tire may
be used as a temporary measure. Make sure
that you use the proper size and type (summer
or winter tire).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addition-
ally equip your vehicle with a TIREFIT kit if you
mount tires that do not feature run-flat charac-
teristics, e.g. winter tires. A TIREFIT kit can be
obtained from a qualified specialist workshop,
for example.
