DOT, Tire Identification Number (TIN) U.S. tire regulations prescribe that every manufacturer of new tires or retreader has to imprint a TIN in or on the sidewall of each tire produced.

The TIN is a unique identification number. The TIN enables the tire manufacturers to inform purchasers of recalls and other safety- relevant matters. It makes it possible for the purchaser to easily identify the affected tires. The TIN is made up of manufacturer identification code ;, tire size =, tire type code ? and manufacturing date A. i Tire data is vehicle-specific and may deviate from the data in the example.

DOT (Department of Transportation): tire symbol : marks that the tire complies with the requirements of the U.S. Department of Transportation. Manufacturer identification code: manufacturer identification code ; provides details on the tire manufacturer. New tires

262 Definition of terms for tires and loading

have a code with two symbols. Retreaded tires have a code with four symbols. Further information about retreaded tires (Y page 242). Tire size: identifier = describes the tire size. Tire type code: tire type code ? can be used by the manufacturer as a code to describe specific characteristics of the tire. Date of manufacture: date of manufacture A provides information about the age of a tire. The first and second positions represent the week of manufacture, starting with "01" for the first calendar week. Positions three and four represent the year of manufacture. For example, a tire that is marked with "3208", was manufactured in week 32 in 2008.

Additional information on particular driving conditions is located on the tire pressure table on the inside of the fuel filler flap.

Definition of terms for tires and loading 263

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.

Wheel rim This is the part of the wheel on which the tire is mounted.

GAWR (Gross Axle Weight Rating) The GAWR is the maximum gross axle weight rating. 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.

Speed index The speed index is part of the tire identification. It specifies the speed range for which the tire is approved.

GTW (Gross Trailer Weight) The GTW is the sum of the weight of a trailer and the weight of the load, luggage, accessories etc. on the trailer.

GVW (Gross Vehicle Weight) The gross vehicle weight includes 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 permitted gross weight of the fully laden vehicle (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 weight of the laden vehicle The maximum weight is the sum of the curb weight of the vehicle, the weight of the accessories, the maximum load 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. 100 kilopascal (kPa) is the equivalent of 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 and also includes the air-conditioning system and optional equipment if these are installed on the vehicle, but does not include passengers or luggage.

264 Definition of terms for tires and loading

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

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

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

PSI (pounds per square inch) Standard unit of measurement 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 every 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 3 hours or not have traveled more than 1.6 km (1 mile) in this time.

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.

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

Weight of optional extras The combined weight of those optional extras that weigh more than the replaced standard part and more than 2.3 kg (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 the weight of the accessories.

TIN (Tire Identification Number) This is a unique identification number 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.

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

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

Changing a wheel

265

TWR (permissible trailer drawbar noseweight) The TWR is the maximum permissible weight that may act on the ball coupling of the trailer tow hitch.

Wear indicator 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.

Distribution of the vehicle occupants Distribution of vehicle occupants over designated seat positions in a vehicle.

Maximum permissible payload weight Nominal load and luggage load plus 68 kilograms (150 lb) multiplied by the number of seats in the vehicle.

Changing a wheel Flat tire The "Roadside Assistance" section (Y page 226) 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.

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 pressure and reactivate the tire pressure monitor (Y page 249) if necessary. Information on changing a wheel and mounting the spare wheel (Y page 226). ! 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. Only have tires changed at a qualified specialist workshop.

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

266 Wheel and tire combinations

benefits if the correct direction of rotation is maintained. An arrow on the sidewall of the tire indicates its correct direction of rotation. You may mount the spare wheel against the direction of rotation. Adhere to the time restriction on use as well as the speed limitation specified on the spare wheel.

Storing wheels Store tires 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 (concentrated-power jets) to clean your vehicle, especially for cleaning tires. You could otherwise damage the tires and cause an accident.

Wheel and tire combinations Please bear the following in mind G WARNING Replace rims or tires with the same designation, manufacturer and type as shown on the original part. For further information contact an authorized Mercedes-Benz Center. If incorrectly sized rims and tires are mounted, the wheel brakes or suspension components can be damaged. Also, the operating clearance of the wheels and the tires may no longer be correct. G WARNING Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them.

When replacing rims, only use genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident. Retreaded tires are not tested or recommended by Mercedes-Benz, since previous damage cannot always be recognized on retreads. The operating safety of the vehicle cannot be assured when such tires are used. G WARNING If you notice sudden significant vibrations or unusual handling performance or if you suspect that damage has occurred to the vehicle, you should activate the hazard warning lamps, gently reduce speed and carefully head for an area that is located at a safe distance from the road. Check the tires and the underside of the vehicle for damage. If the vehicle seems unsafe, have the vehicle towed away to the nearest Mercedes-Benz Center or tire dealer to be repaired. G WARNING Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You might lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build- up and possibly a fire.

! For safety reasons, Mercedes-Benz recommends that you only use tires, wheels and accessories which have been approved by Mercedes-Benz specifically for your vehicle. These tires have been specially adapted for use with the driving safety systems, such as ABS or ESP®. 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 wheels, tires 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 245). i Notes on vehicle tires:

Always: Rmount tires of the same size on a given

axle (left/right)

Rmount tires of the same type on your vehicle at a given time (summer tires, winter tires, all-weather tires, all-terrain tires)

Fuel Important safety notes G WARNING Gasoline is highly flammable and poisonous. It burns violently and can cause serious personal injury. Never allow sparks, flames or smoking materials near gasoline. Turn off the engine before refueling.

Whenever you are around gasoline, avoid inhaling fumes and any skin or clothing contact. 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 may be used.

21 Mixed with water or premixed washer fluid with antifreeze protection.

274 Service products and capacities

If there is no premium-grade unleaded gasoline available and regular-grade unleaded gasoline may be used; please observe the following precautions: Ronly fill the fuel tank to half full with

regular-grade 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. Rif the vehicle is carrying a light load, e.g. two passengers without luggage, do not allow the engine to rev above 3,000 rpm.

Rif the vehicle is fully loaded or is being

operated in mountainous terrain, do not depress the accelerator pedal further than Ô 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 in engine design is the creation of carbon deposits during the process of burning fuel. 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 problems, e.g.: Rlonger engine warm-up phase Runeven idle Rengine noise Rmisfiring Rloss of power In areas where carbon deposits can build up, because of the lack of availability of gasoline with the corresponding additives, 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://bevo.mercedes-benz.com for a list of approved products. Comply with the instructions for use on the product label. 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. For this reason, only use engine oils and oil filters that are approved for vehicles with a service system. For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center or go to the Internet site http://bevo.mercedes-benz.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.

This could damage the engine.

Engine oil viscosity Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity,

Service products and capacities

275

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.

Refrigerant of the air-conditioning system The air-conditioning system is filled with R134a (HFC) 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.

276 Service products and capacities

You should have the brake fluid renewed at regular intervals. The brake fluid change intervals can be found in the Maintenance 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 engine cooling system is not 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. Aluminum components in the engine make it necessary to use anticorrosion/antifreeze coolant which has been specifically formulated 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 Maintenance 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 Maintenance 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 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 325.0
antifreeze/corrosion inhibitor should be added. Have the engine cooling system checked for possible leaks.
