Tire-change tool kit
The tire-change tool kit can be found in thestowage well under the trunk floor(Ypage 252).
CBag containing the tire-changing tools
BagCwith the tire-changing tools contains:
Rjack
Rlug wrench
Ralignment bolt
Rwheel chock
Rgloves
Depending on the equipment, tools requiredfor a wheel change, such as a jack or a lugwrench, are not available in all vehicles. Toolsapproved for your vehicle are available at aqualified specialist workshop.
Flat tire
Preparing the vehicle
Your vehicle may be equipped with:
Rtires with run-flat characteristics(MOExtended tires) (Ypage 278)
Vehicle preparation is not necessary onvehicles with MOExtended tires.
Ra TIREFIT kit (Ypage 277)
Vehicles with the Mercedes-Benz emer-gency call system:in the event of a flat tire,you can contact the Mercedes-Benz emer-gency call system customer center.
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.
Information on changing and mounting wheels(Ypage 313).
XStop the vehicle on solid, non-slippery andlevel ground, as far away as possible fromtraffic.
XSwitch on the hazard warning lamps.
XSecure the vehicle against rolling away(Ypage 146).
XIf possible, bring the front wheels into thestraight-ahead position.
XSwitch off the engine.
XVehicles without KEYLESS-GO:removethe SmartKey from the ignition lock.
XVehicles with KEYLESS-GO:open the driv-er's door.The vehicle electronics are now in positionZ. This is the same as the SmartKey havingbeen removed.
XVehicles with KEYLESS-GO:remove theStart/Stop button from the ignition lock(Ypage 126).
XMake sure that the passengers are notendangered as they do so. Make sure thatno one is near the danger area while awheel is being changed. Anyone who is notdirectly assisting in the wheel changeshould, for example, stand behind the bar-rier.
XGet out of the vehicle. Pay attention to traf-fic conditions when doing so.
XClose the driver's door.
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 307).
MOExtended tires may only be used in con-junction with an active tire pressure monitor.

Maximum permissible gross vehicle
weight rating
XSpecification for maximum gross vehicleweightCis listed in the Tire and LoadingInformation placard: "The combined weightof occupants and cargo should neverexceed XXX kilograms or XXX lbs."
The gross weight of all vehicle occupants, loadand luggage must not exceed the specifiedvalue.
iThe specifications shown on the Tire andLoading Information placard in the illustra-tion are examples. The maximum permissi-ble gross vehicle weight rating is vehicle-specific and may differ from that in the illus-tration. You can find the valid maximum per-missible gross vehicle weight rating for yourvehicle on the Tire and Loading Informationplacard.
Number of seats
Maximum number of seatsCindicates themaximum number of occupants allowed totravel in the vehicle. This information can befound on the Tire and Loading Informationplacard.
iThe specifications shown on the Tire andLoading Information placard in the illustra-tion are examples. The number of seats isvehicle-specific and can differ from thedetails shown. The number of seats in yourvehicle can be found on the Tire and Load-ing Information placard.
Determining the correct load limit
Step-by-step instructions
The following steps have been developed asrequired of all manufacturers under Title 49,Code of U.S. Federal Regulations, Part 575pursuant to the "National Traffic and MotorVehicle Safety Act of 1966".
XStep 1:Locate the statement "The com-bined weight of occupants and cargo shouldnever exceed XXX kg or XXX lbs." on yourvehicle’s Tire and Loading Information plac-ard.
XStep 2:Determine the combined weight ofthe driver and passengers that will be ridingin your vehicle.
XStep 3:Subtract the combined weight ofthe driver and passengers from XXX kilo-grams or XXX lbs.
XStep 4:The resulting figure equals the avail-able amount of cargo and luggage loadcapacity. For example, if the "XXX" amountequals 1400 lbs and there will be five 150-lbpassengers in your vehicle, the amount of
304Loading the vehicle
Wheels and tires

available cargo and luggage load capacity is650 lbs (1400 - 750 (5 x 150) = 650 lbs).
XStep 5:Determine the combined weight ofluggage and cargo being loaded on the vehi-cle. That weight may not safely exceed theavailable cargo and luggage load capacitycalculated in step 4.
Example: steps 1 to 3
The following table shows examples on how tocalculate total and cargo load capacities withvarying seating configurations and number andsize of occupants. The following examples usea load limit of 1500 lbs (680 kg).This is forillustration purposes only.Make sure youare using the actual load limit for your vehiclestated on your vehicle's Tire and Loading Infor-mation placard (Ypage 303).
The greater the combined weight of the occu-pants, the lower the maximum luggage load.

Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optionalequipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-sponds to 1 psi. Another unit for tire pressureis bar. 100 kilopascals (kPa) are the equivalentof 1 bar.
Load index
In addition to the load-bearing index, the loadindex may also be imprinted on the sidewall ofthe tire. This specifies the load-bearing capa-city more precisely.
Curb weight
The weight of a vehicle with standard equip-ment including the maximum capacity of fuel,oil and coolant. It also includes the air-condi-tioning system and optional equipment if theseare installed in the vehicle, but does notinclude passengers or luggage.
Maximum load rating
The maximum load rating is the maximum per-missible weight in kilograms or lbs for which atire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for onetire.
Maximum load on one tire
Maximum load on one tire. This is calculatedby dividing the maximum axle load of one axleby two.
PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire widthin percent.
Tire pressure
This is pressure inside the tire applying an out-ward force to each square inch of the tire'ssurface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal(kPa) or in bar. The tire pressure should onlybe corrected when the tires are cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked with the tiresout of direct sunlight for at least three hoursand
Rif the vehicle has not been driven furtherthan 1 mile (1.6 km)
Tread
The part of the tire that comes into contactwith the road.
Bead
The tire bead ensures that the tire sitssecurely on the wheel. There are several steelwires in the bead to prevent the tire from com-ing loose from the wheel rim.
Sidewall
The part of the tire between the tread and thebead.
Weight of optional extras
The combined weight of those optional extrasthat weigh more than the replaced standardparts and more than 2.3 kg (5 lbs). Theseoptional extras, such as high-performancebrakes, level control, a roof rack or a high-per-formance battery, are not included in the curbweight and the weight of the accessories.
TIN (Tire Identification Number)
This is a unique identifier which can be usedby a tire manufacturer to identify tires, forexample for a product recall, and thus identifythe purchasers. The TIN is made up of themanufacturer's identity code, tire size, tiretype code and the manufacturing date.
Load bearing index
The load bearing index (also load index) is acode that contains the maximum load bearingcapacity of a tire.
Traction
Traction is the result of friction between thetires and the road surface.
