MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat char-
acteristics), you can continue to drive you rvehi-
cle even if there is atotal loss of pressure in one
or more tires. The affected tire must not show
any clearl yvisible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You wil lfind this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index (
Ypage 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:
Robserve the instructions in the display mes-
sages (Ypage 196).
Rcheck the tire for damage.
Rif 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 yladen. In addition to the vehicle load
,the driving dis-
tance possible depends upon:
Rvehicle speed
Rroad condition
Routsid etemperature
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 amaximum speed of
50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for you rvehicle's
tires:
Rsize
Rtype and
Rthe "MOExtended" mark
If at ire has gone flat and cannot be replaced
with aMOExtended tire, astandard tire may be
used as atemporary measure. Make sure that
you use the proper size and type (summe ror
winter tire).
Vehiclese quipped with MOExtended tires are
not equipped with aTIREFIT kit at the factory. It
is therefore recommended that you additionally
equi pyourvehicle with aTIREFIT kit if y
ou mount
tires that do not feature run-flat properties, e.g.
winter tires. ATIREFIT kit is available, for exam-
ple, from aqualifieds pecialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is arisk of an accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacle s(curbs, potholes,
off-road). This applies in particular to aladen
vehicle.
Stop driving in emergency mode if:
Ryou hear banging noises.
Rthe vehicle starts to shake.

Fuses
Important safety notes
GWARNING
If you manipulate or bridge afaulty fuse or if
you replace it with afuse with ahigher amper-
age, the electric cables could be overloaded.
This could result in afire. There is arisk of an
accident and injury.
Alwaysr eplace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of the
same rating, which you can recognize by 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 (
Ypage 241).
If an ewly inserted fuse also blows, have the
cause traced and rectified at aqualified special-
ist workshop, e.g. an authorized Mercedes-Benz
Center.
!Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Otherwise, componentsors ystems could be
damaged.
!Make sure that no moisture can enter the
fuse box when the cover is open.
!When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper-
ation of the fuses.
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows, all the compo-
nentsont he circuit and their functions stop
operating.

sure loss warning system.
The tire pressure monitor is not able to warn you
ofas udden loss of pressure, e.g. if the tire is
penetrated by aforeign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully .Avoid abrupt steering
movements.
The function of the tire pressure loss warning
system is limited or delayed if:
Rsnow chains are mounted on your vehicle's
tires.
Rroad conditions are wintry.
Ryou are driving on sand or gravel.
Ryou adopt avery sporty driving style (corner-
ing at high speeds or driving with high rates of acceleration).
Ryou drive with aheavy load.
Restarting the tire pressure loss warn-
ing system
Restart the tire pressure loss warning system if
you have:
Rchanged the tire pressure
Rchanged the wheels or tires
Rmounted new wheels or tires
XBefore restarting, make sure that the tire
pressures are set properly on all four tires for
the respective operating conditions.
The recommended tire pressure can be found
on the Tire and Loading Information placard
on the B-pillar. Additionally, atire pressure
table is attached to the fuel filler flap. The tire pressure loss warning system can only give
reliable warnings if you have set the correct
tire pressure. If an incorrect tire pressure is
set, these incorrect values will be monitored.
XAlso observe the notes in the section on tire
pressures (Ypage 258).
XMake sure that the SmartKey is in position 2
in the ignition lock (Ypage 115).

Tire pressure monitor
General notes
If at ire pressure monitor is installed, the vehi-
cle's wheels have sensors that monitor the tire
pressures in all four tires. The tire pressure mon-
itor warns you if the pressure drops in one or
more of the tires. The tire pressure monitor only
functions if the corresponding sensors are
installed in all wheels.
Information on tire pressures is displayed in the
multifunction display. After afew minutes of
driving, the current tire pressure of each tire is
shown in the Serv.
menu of the multifunction
display.
Example: current tire pressure display
