MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flatcharacteristics), you can continue to drive yourvehicle even if there is a total loss of pressurein one or more tires. The affected tire must notshow any clearly visible damage.
You can recognize an MOExtended tire by theMOExtended marking which appears on thesidewall of the tire. You will find this markingnext to the tire size designation, the load-bear-ing capacity and the speed index(Ypage 320).
MOExtended tires may be used only in con-junction with an activated tire pressure losswarning system (Canada only) or tire pressuremonitor (USA only).
If a pressure loss warning messageappears in the multifunction display:
Robserve the instructions in the display mes-sages (Ypage 223).
Rcheck the tire for damage
Rif driving on, observe the following notes
The driving distance possible in run-flat modeis approximately 50 miles (80 km) when thevehicle is partially laden. When the vehicle isfully laden it is approximately 19 miles(30 km).
In addition to the vehicle load, the driving dis-tance possible depends upon:
RVehicle speed
RRoad condition
ROutside temperature
The driving distance possible in run-flat modemay be reduced by extreme driving conditionsor maneuvers, or it can be increased through amoderate style of driving.
The driving distance possible in run-flat modeis counted from the moment the tire pressureloss warning appears in the multifunction dis-play.
You must not exceed the maximum permissi-ble speed for limp-home mode of 50 mph(80 km/h).
When replacing one or all tires, please observethe following specifications for your vehicle'stires:
RSize
RType and
RThe "MOExtended" marking
If a tire has gone flat and cannot be replacedwith an MOExtended tire, a standard tire maybe used as a temporary measure. Make surethat you use the proper size and type (summeror winter tire).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory.It is therefore recommended that you addition-ally equip your vehicle with a TIREFIT kit if youmount tires that do not feature run-flat charac-teristics, e.g. winter tires. A TIREFIT kit may beobtained from a qualified specialist workshop.

GWARNING
A flat tire will severely affect the driving
characteristics as well as the steering and
braking of the vehicle. There is a risk of an
accident.
Tires without run-flat characteristics:
RDo not drive on with a flat tire.
RChange the flat tire immediately with an
emergency spare wheel or spare wheel.
Alternatively, consult a qualified specialist
workshop.
Tires with run-flat characteristics:
RObserve the information and warning
notes on MOExtended tires (run-flat tires).
Accessories that are not approved for yourvehicle by Mercedes-Benz or are not beingused correctly can impair the operating safety.
Before purchasing and using non-approvedaccessories, visit a qualified specialist work-shop and inquire about:
Rsuitability
Rlegal stipulations
Rfactory recommendations
Further information regarding wheels and tirescan be found under "Wheel/tire combinations"(Ypage 329).
You can ask for information regarding permit-ted wheel/tire combinations at an authorizedMercedes-Benz Center.
Information on tire pressure can be found:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side(Ypage 316)
Rin the tire pressure table in the fuel filler flap(Ypage 144)
Runder "Tire pressure" (Ypage 307)
Operation
Information on driving
Check the tire pressure when the vehicle isheavily laden and adjust prior to a trip.
While driving, pay attention to vibrations,noises and unusual handling characteristics,e.g. pulling to one side. This may indicate thatthe wheels or tires are damaged. If you sus-pect that a tire is defective, reduce your speedimmediately. Stop the vehicle as soon as pos-sible to check the wheels and tires for dam-age. Hidden tire damage could also be causingthe unusual handling characteristics. If youfind no signs of damage, have the tires andwheels checked at a qualified specialist work-shop.
When parking your vehicle, make sure that thetires do not get deformed by the curb or otherobstacles. If they cannot be avoided, driveover obstacles such as curbs slowly and at anobtuse angle. Otherwise, you may damage thewheels or tires.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tires regularly for signs of dam-
age and replace any damaged tires immedi-
ately.
304Operation
Wheels and ti res

Check wheels and tires for damage at leastonce a month. Check wheels and tires afterdriving off-road or on rough road test tracks.Damaged wheels can cause a loss of tire pres-sure. Pay particular attention to damage suchas:
Rcuts in the tires
Rpunctures in the tires
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and thecondition of the tread across the whole widthof all tires (Ypage 305). If necessary, turn thefront wheels to full lock in order to inspect theinner side of the tire surface.
All wheels must have a valve cap to protectthe valve against dirt and moisture. Do notmount anything onto the valve other than thestandard valve cap or other valve capsapproved by Mercedes-Benz for your vehicle.Do not use any other valve caps or systems,e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tiresparticularly prior to long trips. Adjust the tirepressure as necessary (Ypage 307).
Observe the notes on the emergency sparewheel (Ypage 330).
The service life of tires depends, among otherthings, on the following factors:
RDriving style
RTire pressure
RDistance covered
Notes on tire tread
GWARNING
If there is insufficient tire tread, the tire trac-
tion decreases. The tire tread is no longer
able to dissipate water. This increases the
risk of hydroplaning when the road surface
is wet, particularly when the vehicle's speed
is not adapted to the road conditions. There
is a risk of an accident.
When the tire pressure is too high or too
low, tires may wear differently at different
points on the tire tread. Therefore, regularly
check the tire tread depth and the condition
of the tread across the whole width of all
tires.
Minimum tire tread depth on:
RSummer tires:

(tires with run-flat characteristics)" section(Ypage 288).
ROnly mount tires of the correct size onto thewheels.
RBreak in new tires at moderate speeds forthe first 60 miles (100 km). The new tiresonly reach their full performance after thisdistance.
RDo not drive with tires which have too littletread depth. This significantly reduces thetraction on wet roads (hydroplaning).
RReplace the tires after six years at the lat-est, regardless of wear.
Observe the notes on the emergency sparewheel (Ypage 330).
MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flatcharacteristics), you can continue to drive yourvehicle even if there is a total loss of pressurein one or more tires.
MOExtended tires may only be used in con-junction with an activated tire pressure losswarning system (Canada only) or tire pressuremonitor (USA only) and only on wheels specifi-cally tested by Mercedes-Benz.
Notes on driving with MOExtended tires with aflat tire (Ypage 288).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory.It is therefore recommended that you addition-ally equip your vehicle with a TIREFIT kit if youmount tires that do not feature run-flat charac-teristics, e.g. winter tires. A TIREFIT kit may beobtained from a qualified specialist workshop.
Winter operation
General notes
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"section (Ypage 325).
Driving with summer tires
At temperatures below 45 ‡ (+7 †), summertires lose elasticity and therefore traction andbraking power. Change the tires on your vehi-cle to M+S tires. Using summer tires at verycold temperatures could cause cracks to form,thereby damaging the tires permanently.Mercedes-Benz cannot accept responsibilityfor this type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tires regularly for signs of dam-
age and replace any damaged tires immedi-
ately.
M+S tires
GWARNING
M+S tires with a tire tread depth of less than

When you have mounted the M+S tires:
XCheck the tire pressures (Ypage 307).
XRestart the tire pressure monitor (USA only)(Ypage 314).
XRestart the tire pressure loss warning sys-tem (Canada) (Ypage 311)
Snow chains
GWARNING
If snow chains are mounted on the rear
wheels, the snow chains could cause abra-
sion to the vehicle body or to chassis com-
ponents. This could cause damage to the
vehicle or the tires. There is a risk of an
accident.
To avoid hazardous situations:
Rnever mount snow chains on the rear
wheels
Ronly mount snow chains in pairs on the
front wheels.
!On some tire sizes there is not enoughspace for snow chains. To avoid damage tothe vehicle or tires, observe the "Wheel andtire combinations" section under "Tires andwheels".
For safety reasons, Mercedes-Benz recom-mends that you only use snow chains thathave been specially approved for your vehicleby Mercedes-Benz, or are of a correspondingstandard of quality. For more information,please contact a qualified specialist workshop.
If you intend to mount snow chains, pleasebear the following points in mind:
RSnow chains may not be mounted on allwheel/tire combinations. Permissiblewheel-tire combinations (Ypage 329).
ROnly use snow chains when driving on roadscompletely covered by snow. Remove thesnow chains as soon as possible when youcome to a road that is not snow-covered.
RLocal regulations may restrict the use ofsnow chains. Observe the appropriate regu-lations if you wish to mount snow chains.
RDo not exceed the maximum permissiblespeed of 30mph (50 km/h).
RIf snow chains are installed, you cannot useActive Parking Assist (Ypage 176).
You may wish to deactivate ESP®when pullingaway with snow chains installed . This allowsthe wheels to spin in a controlled manner, ach-ieving increased propulsive force (cuttingaction).
