MOExtended tires (tires with run-flat
properties)
General notes With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rv ehi-
cle even if there is at otal loss of pressure in one
or more tires. The affected tire must not show
any clearl yv isible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You wil lf ind this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index ( Y
page 269).
MOExtended tires may only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If ap ressure loss warning message appears
in the multifunction display: R
observe the instructions in the display mes-
sages ( Y
page 196).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 km) when the vehi-
cle is partially laden and approximately 19 miles
(30 km) when the vehicle is full yl aden. In addition to the vehicle load ,t he driving dis-
tance possible depends upon: R
vehicle speed R
road condition R
outsid et emperature
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 display.
You must not exceed am aximum speed of
50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for you rv ehicle's
tires: R
size R
type and R
the "MOExtended" mark
If at ire has gone flat and cannot be replaced
with aM OExtended tire, as tandard tire may be
used as at emporary measure. Make sure that
you use the proper size and type (summe ro r
winter tire).
Vehicle se quipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefore recommended that you additionally
equi py ou rv ehicle with aT IREFIT kit if y ou mount
tires
that do not feature run-flat properties, e.g.
winter tires. AT IREFIT kit is available, for exam-
ple, from aq ualifie ds pecialist workshop.

Important safety notes
G WARNING
If you manipulate or bridge af aulty fuse or if
you replace it with af use with ah igher amper-
age, the electric cables could be overloaded.
This could result in af ire. There is ar isk of an
accident and injury.
Alway sr eplace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of the

color and value .T he fuse ratings are listed in the
fuse allocation chart.
The fuse allocation chart is located in the vehicle
tool kit in the stowage compartment under the
trunk floor ( Y
page 241).
If an ewly inserted fuse also blows, have the
cause traced and rectified at aq ualified special-
ist workshop, e.g. an authorized Mercedes-Benz
