Speed rating
The speed rating is part of the tire identification.It specifies the speed range for which the tire isapproved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight ofthe vehicle including fuel, tools, the spare wheel,accessories installed, occupants, luggage andthe drawbar noseweight, if applicable. The grossvehicle weight must not exceed the gross vehi-cle weight rating GVWR as specified on the vehi-cle identification plate on the B-pillar on thedriver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible grossweight of a fully loaded vehicle (the weight of thevehicle including all accessories, occupants,fuel, luggage and the drawbar noseweight, ifapplicable). The gross vehicle weight rating isspecified on the vehicle identification plate onthe B-pillar on the driver's side.
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 pressure isbar. 100 kilopascals (kPa) are the equivalent of1 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 capacitymore precisely.
Curb weight
The weight of a vehicle with standard equipmentincluding the maximum capacity of fuel, oil andcoolant. It also includes the air-conditioning sys-tem and optional equipment if these are instal-led in the vehicle, but does not include passen-gers or luggage.
Maximum load rating
The maximum tire load is the maximum permis-sible weight in kilograms or lbs for which a tire isapproved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one tire.
Maximum load on one tire
Maximum load on one tire. This is calculated bydividing the maximum axle load of one axle bytwo.
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's sur-face. The tire pressure is specified in pounds persquare inch (psi), in kilopascal (kPa) or in bar.The tire pressure should only be corrected whenthe 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 further than1 mile (1.6 km)
Tread
The part of the tire that comes into contact withthe road.
Bead
The tire bead ensures that the tire sits securelyon the wheel. There are several steel wires in thebead to prevent the tire from coming loose fromthe wheel rim.
Sidewall
The part of the tire between the tread and thebead.

the tires are installed corresponding to thedirection of rotation.
An arrow on the sidewall of the tire indicates itscorrect direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,dry and preferably dark place. Protect the tiresfrom oil, grease, gasoline and diesel.
Mounting a wheel
Preparing the vehicle
XStop the vehicle on solid, non-slippery andlevel ground.
XApply the electric parking brake manually.
XBring the front wheels into the straight-aheadposition.
XShift the transmission to position].
XMake sure that the vehicle level is set to "Nor-mal" on vehicles with AIR BODY CONTROL(Ypage 173).
XSwitch off the engine.
XVehicles without KEYLESS-GO:remove theSmartKey from the ignition lock.
XVehicles with KEYLESS-GO start functionor KEYLESS-GO:open the driver's door.The vehicle electronics are now in position

must be positioned vertically, directly under
the jacking point of the vehicle.
!Only position the jack at the appropriatejacking point of the vehicle. Otherwise, youcould damage the vehicle.
Observe the following when raising the vehi-cle:
RTo raise the vehicle, only use the vehicle-spe-cific jack that has been tested and approvedby Mercedes-Benz. If used incorrectly, thejack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold thevehicle for a short time while a wheel is beingchanged. It must not be used for performingmaintenance work under the vehicle.
RAvoid changing the wheel on uphill and down-hill slopes.
RBefore raising the vehicle, secure it from roll-ing away by applying the parking brake andinserting wheel chocks. Do not disengage theparking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat andnon-slip surface. On a loose surface, a large,flat, load-bearing underlay must be used. On aslippery surface, a non-slip underlay must beused, e.g. rubber mats.
RDo not use wooden blocks or similar objectsas a jack underlay. Otherwise, the jack will notbe able to achieve its load-bearing capacitydue to the restricted height.
RMake sure that the distance between theunderside of the tires and the ground does notexceed 1.2 in (3 cm).
RDo not place your hands or feet under theraised vehicle.
RDo not lie under the vehicle.
RDo not start the engine when the vehicle israised.
RNever open or close a door or the tailgatewhen the vehicle is raised.
RMake sure that no persons are present in thevehicle when the vehicle is raised.
XUsing lug wrenchC, loosen the bolts on thewheel you wish to change by about one fullturn. Do not unscrew the bolts completely.
The jacking points are located just behind thefront wheel housings and just in front of the rearwheel housings (arrows).
XTake the ratchet wrench out of the tire-chang-ing tool kit and place it on the hexagon nut ofthe jack so that the lettersAUFare visible.
XPosition jack

Lowering the vehicle
GWARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
XPlace the ratchet wrench onto the hexagonnut of the jack so that the lettersABare visi-ble.
XTurn the ratchet wrench until the vehicle isonce again standing firmly on the ground.
XPlace the jack to one side.
XTighten the wheel bolts evenly in a crosswisepattern in the sequence indicated (Cto

Observe the notes on recommended tire pres-sures under various operating conditions(Ypage 333).
Check tire pressures regularly, and only whenthe tires are cold. Comply with the maintenancerecommendations of the tire manufacturer inthe vehicle document wallet.
Notes on the vehicle equipment – always equipthe vehicle:
Rwith tires of the same size on a given axle (leftand right)
Rwith the same type of tires at a given time(summer tires, winter tires, MOExtendedtires)
Exception: it is permissible to install a differ-ent type or make in the event of a flat tire.Observe the "MOExtended tires (tires withrun-flat characteristics" section (Ypage 315).
Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory. Itis therefore recommended that you additionallyequip your vehicle with a TIREFIT kit if you mounttires that do not feature run-flat properties, e.g.winter tires. A TIREFIT kit may be obtained froma qualified specialist workshop.
