pressure label on the inside of the fuel filler flap.

Increased vehicle weight due to optional equipment This is the combined weight of all standard and optional equipment available for the vehicle, regardless of whether it is actually installed on the vehicle or not.

Rim This is the part of the wheel on which the tire is mounted.

GAWR (Gross Axle Weight Rating) The GAWR is the maximum permissible axle weight. The actual load on an axle must never exceed the gross axle weight rating. The gross axle weight rating can be found on the vehicle identification plate on the B-pillar on the driver's side.

Tire speed rating The tire speed rating is part of the tire identification. It specifies the speed range for which the tire is approved.

GVW (Gross Vehicle Weight) The gross vehicle weight comprises the weight of the vehicle including fuel, tools, the spare wheel, accessories installed, occupants, luggage and the drawbar noseweight if applicable. The gross vehicle weight must not exceed the gross vehicle weight rating GVWR as specified on the vehicle identification plate on the B pillar on the driver's side.

GVWR (Gross Vehicle Weight Rating) The GVWR is the maximum permissible gross weight of a fully loaded vehicle (the weight of the vehicle including all accessories, occupants, fuel, luggage and the drawbar noseweight if applicable). The gross vehicle weight rating is specified on the vehicle identification plate on the B-pillar on the driver's side.

Maximum loaded vehicle weight The maximum weight is the sum of the curb weight of the vehicle, the weight of the accessories, the total load limit and the weight of the optional equipment installed at the factory.

Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa is the equivalent of 1 psi. Another unit for tire pressure is bar. There are 100 kilopascals (kPa) to 1 bar.

Load index In addition to the load bearing index, the load index may also be imprinted on the sidewall of the tire. This specifies the load bearing capacity more precisely.

Curb weight The weight of a vehicle with standard equipment including the maximum capacity of fuel, oil and coolant. It also includes the air- conditioning system and optional equipment if these are installed in the vehicle, but does not include passengers or luggage.

Definition of terms for tires and loading 337

Maximum load rating The maximum load rating in kilograms or pounds is the maximum weight for which a tire is approved.

Tread The part of the tire that comes into contact with the road.

Maximum permissible tire pressure Maximum permissible tire pressure for one tire.

Bead The tire bead ensures that the tire sits securely on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from the wheel rim.

Maximum load on one tire Maximum load on one tire. This is calculated by dividing the maximum axle load of one axle by two.

Sidewall The part of the tire between the tread and the bead.

PSI (pounds per square inch) A standard unit of measure for tire pressure.

Aspect ratio Relationship between tire height and tire width in percent.

Tire pressure This is pressure inside the tire applying an outward force to each square inch of the tire's surface. The tire pressure is specified in pounds per square inch (psi), in kilopascal (kPa) or in bar. The tire pressure should only be corrected when the tires are cold. For this, the vehicle must have been stationary for at least three hours or not have traveled more than 1.6 km (1 mile) in this time.

Tire pressure of cold tires Tire pressure when the vehicle has been stationary for at least three hours or not have traveled more than 1.6 km (1 mile) in this time.

Weight of optional extras The combined weight of those optional extras that weigh more than the replaced standard part and more than 2.3 kilograms (5 lbs). These optional extras, such as high- performance brakes, level control, a roof rack or a high-performance battery, are not included in the curb weight and accessory weight.

TIN (Tire Identification Number) This is a unique identifier which can be used by a tire manufacturer to identify tires, for example for a product recall, and thus identify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire type code and the manufacturing date.

Load bearing index The load bearing index (also load index) is a code that contains the maximum load bearing capacity of a tire.

338 Changing a wheel

Traction Traction is the result of friction between the tires and the road surface.

Treadwear indicators Narrow bars (tread wear bars) that are distributed over the tire tread. If the tire tread is level with the bars, the wear limit of 1/16 in (1.6 mm) has been reached.

Occupant distribution The distribution of occupants in a vehicle at their designated seating positions.

Total load limit Rated cargo and luggage load plus 68 kilograms (150 lbs) times the vehicle's designated seating capacity.

Changing a wheel Flat tire The "Roadside Assistance" section (Y page 296) contains information and notes on how to deal with a flat tire. It also provides instructions on changing a wheel or mounting the spare wheel/emergency spare wheel.

Interchanging the wheels G WARNING Rotate front and rear wheels only if the tires are of the same dimension. If your vehicle is equipped with mixed-size tires (different tire dimensions front vs. rear), tire rotation is not possible. G WARNING Have the tightening torque checked after changing a wheel. Wheels could become

loose if not tightened with a torque of 96 lb-ft (130 Nm). Only use genuine Mercedes-Benz wheel bolts specified for your vehicle's rims.

The wear patterns on the front and rear tires differ, depending on the operating conditions. Rotate the wheels before a clear wear pattern has formed on the tires. Front tires typically wear more on the shoulders and the rear tires in the center. If your vehicle's tire configuration allows, you can rotate the wheels according to the intervals in the tire manufacturer's warranty book in your vehicle documents. If this is not available, the tires should then be replaced every 3000 to 6000 miles (5000 to 10,000 km), or earlier if the tire wear requires this. Do not change the direction of wheel rotation. Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is interchanged. Check the tire pressures. Information on changing a wheel and mounting the spare wheel (Y page 296). ! On vehicles equipped with a tire pressure

monitor, electronic components are located in the wheel. Tire-mounting tools should not be used near the valve. This could damage the electronic components. Always have the tires changed at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

Direction of rotation Tires with a specified direction of rotation have additional benefits, e.g. if there is a risk of hydroplaning. You will only gain these benefits if the correct direction of rotation is maintained. An arrow on the sidewall of the tire indicates its correct direction of rotation.

Wheel and tire combinations

339

You may mount a spare wheel/emergency spare wheel against the direction of rotation. Observe the time restriction on use as well as the speed limit specified on the spare wheel/ emergency spare wheel.

Storing wheels Store wheels that are not being used in a cool, dry and preferably dark place. Protect the tires from oil, grease, gasoline and diesel.

Cleaning the wheels G WARNING Do not use power washers with circular-jet nozzles (dirt grinders) to clean your vehicle, in particular the tires. You could otherwise damage the tires and cause an accident.

Wheel and tire combinations Please bear the following in mind ! For safety reasons, Mercedes-Benz

recommends that you only use Tires and wheels which have been approved by Mercedes-Benz specifically for your vehicle. These tires have been specially adapted for use with the control systems, such as ABS or ESP®, and are marked as follows: RMO = Mercedes-Benz Original RMOE = Mercedes-Benz Original Extended (tires featuring run-flat characteristics)

RMO1 = Mercedes-Benz Original (only

certain AMG tires)

Mercedes-Benz Original Extended tires may only be used on wheels that have been specifically approved by Mercedes-Benz. Only use tires, wheels or accessories tested and approved by Mercedes-Benz. Certain characteristics, e.g. handling, vehicle noise emissions or fuel consumption, may otherwise be adversely

affected. In addition, when driving with a load, tire dimension variations could cause the tires to come into contact with the bodywork and axle components. This could result in damage to the tires or the vehicle. Mercedes-Benz accepts no liability for damage resulting from the use of tires, wheels or accessories other than those tested and approved. Further information about tires, wheels and approved combinations can be obtained from any authorized Mercedes-Benz Center.

i The Tire and Load Information placard with the recommended tire pressures is attached to the B-pillar on the driver's side. Further information about driving at high speeds or driving with vehicle loads that are lighter than the maximum vehicle load can be found in the tire pressure table on the inside of the fuel filler flap. Check tire pressures regularly, and only when the tires are cold. Comply with the maintenance recommendations of the tire manufacturer in the vehicle document wallet.

For further information on the recommended tire inflation pressure and on tire pressures for specific driving conditions, see (Y page 317). i Notes on the vehicle equipment – always

equip the vehicle: Rwith tires of the same size on a given axle

(left/right)

Rwith the same type of tires at a given time (summer tires, winter tires, MOExtended tires)

i On the following pages, you can find

information on approved wheel rims and tire sizes for equipping your vehicle with winter tires. Winter tires are not available from the factory as standard equipment or optional extras. If you want to equip your vehicle with approved winter tires, it may be necessary to obtain wheel rims in the corresponding

348 Service products and capacities

Direct skin contact with fuels and the inhalation of fuel vapors are damaging to your health.

Premium-grade unleaded gasoline ! To ensure the longevity and full

performance of the engine, only premium- grade unleaded gasoline must be used. If no premium-grade unleaded gasoline is available and regular unleaded gasoline must be used, observe the following precautions: Ronly fill the fuel tank to half full with

regular unleaded gasoline and fill the rest with premium-grade unleaded gasoline as soon as possible.

Rdo not drive at the maximum speed. Ravoid sudden acceleration. Rwhen the vehicle is carrying a light load, e.g. two passengers without luggage, do not allow the engine to rev above 3000 rpm.

Rwhen the vehicle is fully loaded or in

mountainous terrain, do not depress the accelerator pedal further than ⅔ of the pedal travel.

Fuel requirements Use only premium-grade unleaded gasoline. The octane number should be at least 91. Details can be found on the gas pump. The octane number is the average value of the Research Octane Number (RON) and the Motor Octane Number (MON): (RON + MON) / 2, also known as knock resistance. Reformulated Gasoline (RFG) and/or unleaded gasoline with additives can be used if the concentration of the additives in the fuel does not exceed 10%, e.g.: REthanol RTAME RETBE RIPA RTBA

For MTBE, the concentration should not exceed 15%. The concentration of methanol in gasoline including other additives must not exceed 3%. Using mixtures of methanol and ethanol is not permitted. Gasohol, a mixture of 10% ethanol and 90% unleaded gasoline, can be used. All of these mix fuels must fulfill the fuel requirements, e.g.: Rknock resistance Rboiling point Rvapor pressure

Additives in gasoline One of the major problems with poor quality fuels is the creation of carbon deposits during the combustion process. Mercedes-Benz recommends that you use fuel brands containing additives that prevent the build-up of carbon deposits. If you use fuels without these additives for an extended period of time, there may be a build up of carbon deposits, especially on the inlet valves and in the combustion chamber. This could lead to engine running problems, e.g.: Rlonger engine warm-up phase Runeven idle Rengine noise Rmisfiring Rloss of power In areas where the availability of gasoline with relevant additives is not adequate, carbon deposits can form. In this case, Mercedes- Benz recommends the use of additives that have been approved for Mercedes-Benz vehicles. Consult an authorized Mercedes-Benz Center or go to the Internet site http://www.mbusa.com (USA only) for a list of approved products. Observe the instructions for use on the product label.

Additives ! Do not use any additives in the engine oil.

This could damage the engine.

Engine oil viscosity Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin. Select an engine oil with an SAE (viscosity) classification suitable for the prevailing outside temperatures. The following table shows the correct SAE classification to be used. The low-temperature characteristics of engine oils can deteriorate significantly, e.g. as a result of aging, soot and fuel deposits. It is therefore strongly recommended that you carry out regular oil changes using an approved engine oil with the appropriate SAE classification.

Do not mix other fuel additives with fuel. This causes unnecessary costs and could damage the engine. ! Do not refuel with low-grade fuel and do not use fuel additives that are not tested and approved for Mercedes-Benz vehicles. Damage to or malfunctions of the fuel system may otherwise occur.

Engine oil Please bear the following in mind The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. You should therefore only use engine oils and oil filters that are approved for vehicles with maintenance systems. For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center or go to the Internet site http://www.mbusa.com (USA only). ! Never use engine oil or an oil filter of a specification other than is necessary to fulfill the prescribed service intervals. Do not change the engine oil or oil filter in order to achieve longer replacement intervals than those prescribed. You could otherwise cause engine damage or damage to the exhaust gas aftertreatment. Follow the instructions in the service interval display regarding the oil change. Otherwise, you may damage the engine and the exhaust gas aftertreatment.

The table shows which engine oils have been approved for your vehicle.

32 BlueEFFICIENCY. 33 Restriction: only SAE 0W-40 or SAE 5W-40 engine oils may be used.

350 Service products and capacities

Refrigerant of the air-conditioning system The air-conditioning system is filled with R134a refrigerant and a special PAG lubricant. ! Never use refrigerant R 12 (CFC) or

mineral lubricants. Otherwise, you could damage the air-conditioning system.

Brake fluid G WARNING The brake fluid constantly absorbs moisture from the air; this lowers its boiling point. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied hard (e.g. when driving downhill). This would impair braking efficiency. You should have the brake fluid renewed at regular intervals. The brake fluid change intervals can be found in the Service Booklet.

Only use brake fluid approved by Mercedes- Benz. Information about approved brake fluids can be obtained from any authorized Mercedes-Benz Center.

Coolant Important safety notes The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks: Ranti-corrosion protection Rantifreeze protection Rraising the boiling point The engine cooling system is filled at the factory with coolant which contains an antifreeze/corrosion inhibitor that ensures protection down to approximately -35 ‡ (-37 † ).

! Only add coolant that has been premixed

with the desired antifreeze protection. Otherwise, the engine could be damaged. Further information on coolants and on filling can be found in the Mercedes-Benz Specifications for Service Products, MB Approval 310.1, e.g. on the Internet at http://bevo.mercedes-benz.com. You can also consult an authorized Mercedes-Benz Center.

! Always use a suitable coolant mixture,

even in countries where high temperatures prevail. Otherwise, the cooling system will not be sufficiently protected from corrosion, and the boiling point will be too low.

If the coolant has antifreeze protection down to -35 ‡ (-37 † ), the boiling point of the coolant in the pressurized system is approximately 266 ‡ (130 † ). Your vehicle has a range of aluminum components. Use of aluminum components in the engine make it necessary to specifically match the antifreeze/corrosion inhibitor in these systems in order to protect the aluminum parts. Using other antifreeze/ corrosion inhibitors without these characteristics affects the service life. The coolant must be used throughout the year in order to maintain the necessary corrosion protection and provide protection from overheating. In the Service Booklet, you can find information on the intervals for renewal. The renewal interval is determined by the coolant type and the engine cooling system design. The renewal interval in the Service Booklet is only valid if the coolant is renewed or replenished with Mercedes-Benz approved products. Therefore, only use MB 326.0
antifreeze/corrosion inhibitor or another Mercedes-Benz approved product of the same specification. Information on other products with the same specifications that are approved by Mercedes-Benz can be obtained at an authorized Mercedes-Benz Center or on the

Vehicle data 351

Internet at http://bevo.mercedes-benz.com. The coolant is checked at every maintenance interval at an authorized Mercedes-Benz Center. The antifreeze/corrosion inhibitor concentration in the engine cooling system should: Rbe at least 50%. This will protect the engine

cooling system against freezing down to approximately -35 ‡ (-37 † ).

Rnot exceed 55% (antifreeze protection to -49 ‡ [-45 † ]); otherwise, heat will not dissipate as effectively.

If the coolant level is too low, MB 326.0
antifreeze/corrosion inhibitor should be added. Have the engine cooling system checked for possible leaks.

Windshield/headlamp cleaning system G WARNING Washer solvent/antifreeze is highly flammable. Do not spill washer solvent/ antifreeze on hot engine parts, because it may ignite and burn. You could be seriously burned.

Use MB SummerFit windshield washer concentrate at temperatures above freezing: X Mix 1 part MB SummerFit with 100 parts

water.

Use MB WinterFit windshield washer concentrate at temperatures below freezing: X At temperatures down to 14 ‡(Ò 10 †): mix
