Maximum load rating

G WARNING Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

Vehicle identification plate Even if you have calculated the total load carefully, you should still make sure that the gross vehicle weight rating and the gross axle weight rating are not exceeded. Details can be found on the vehicle identification plate on the B-pillar on the driver's side (Y page 306). Gross vehicle weight: the gross weight of the vehicle, all passengers, cargo and trailer load/noseweight (if applicable) must not exceed the permissible gross vehicle weight. Gross axle weight rating: the maximum permissible load that can be carried by one axle (front or rear axle). To ensure that your vehicle does not exceed the maximum permissible values (gross vehicle weight and maximum gross axle weight rating), have your loaded vehicle (including driver, occupants, cargo, and full trailer load if applicable) weighed on a suitable vehicle weighbridge.

Trailer load/noseweight Your Mercedes-Benz has been designed primarily to carry passengers and their luggage. Mercedes-Benz does not recommend towing a trailer with your vehicle.

i The actual values for tires are specific to

each vehicle and may deviate from the values in the illustration.

Maximum tire load : is the maximum permitted weight for which the tire is approved.

310 Uniform Tire Quality Grading Standards

Further information on tire loads (Y page 311).

Uniform Tire Quality Grading Standards Overview of Tire Quality Grading Standards

The Uniform Tire Quality Grading is a U.S. Government requirement. Their purpose is to provide drivers with consistent and reliable information regarding tire performance. Tire manufacturers are required to grade tires using three performance factors: tread wear :, tire traction ;, and temperature resistance =. Although not a Government of Canada requirement, all tires made for sale in North America have these grades branded on the sidewall. i The actual values for tires are vehicle-

specific and may deviate from the values in the illustration.

Where applicable, the tire grading information can be found on the tire sidewall between the tread shoulder and maximum tire width. For example: Tread wear Traction 200

Temperature

AA

All passenger car tires must conform to the statutory safety requirements in addition to these grades.

Tread wear The tread wear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified U.S. Government test course. For example, a tire graded 150 would wear one and one-half times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm, due to variations in driving habits, service practices and differences in road characteristics and climate conditions.

Traction G WARNING The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on a wet surface as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. G WARNING If ice has formed on the road, tire traction will be substantially reduced. Under such weather conditions, drive, steer and brake with extreme caution.

The safe speed on a wet, snow covered or icy road is always lower than on dry road surfaces. You should pay special attention to road conditions when temperatures are around the freezing point. Mercedes-Benz recommends a minimum tire tread depth of 1/6 in (4 mm) for all four winter

tires (Y page 296) to maintain normal driving characteristics in winter. Winter tires can reduce the braking distance on snow covered surfaces in comparison to summer tires. Stopping distance, however, is still considerably greater than when the road is not covered with ice or snow. Take appropriate care when driving. ! Avoid wheelspin. This can lead to damage

to the drive train.

Temperature G WARNING The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build-up and possible tire failure.

The temperature grades are A (the highest), B, and C. These represent the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

General: depending on the manufacturer's standards, the size imprinted in the tire wall may not contain any letters or may contain one letter that precedes the size description. If there is no letter preceding the size description (as shown above): these are passenger vehicle tires according to European manufacturing standards. If "P" precedes the size description: these are passenger vehicle tires according to U.S. manufacturing standards. If "LT" precedes the size description: these are light truck tires according to U.S. manufacturing standards. If "T" precedes the size description: these are compact emergency spare wheels at high tire pressure, to be used only temporarily in an emergency. Tire width: tire width : shows the nominal tire width in millimeters. Nominal aspect ratio: aspect ratio ; is the size ratio between the tire height and the tire width and is shown in percent. The aspect

ratio is calculated by dividing the tire width by the tire height. Tire code: tire code = specifies the tire type. "R" represents radial tires. "D" represents diagonal tires, "B" represents diagonal radial tires. Optionally, tires with a maximum speed of over 149 mph (240 km/h) may have "ZR" in the size description depending on the manufacturer (e.g. 245/40 ZR 18). Rim diameter: rim diameter ? is the diameter of the bead seat, not the diameter of the rim flange. The rim diameter is specified in inches (in). Load bearing index: load bearing index A is a numerical code which specifies the maximum load-bearing capacity of a tire. G WARNING The tire load rating must always be at least half of the GAWR of your vehicle. Otherwise, sudden tire failure may be the result which could cause an accident and/or serious injury to you or others. Always replace rims and tires with rims and tires having the same specifications (designation, manufacturer and type) as shown on the original part. G WARNING Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.

Example: The load bearing index 91 is equivalent to a maximum load of 1356 lbs (615 kg) that the tire can carry. For further information on the maximum tire load in kilograms and pounds, see (Y page 309).

For further information on the load bearing index, see Load index (Y page 314). Speed rating: speed rating B specifies the approved maximum speed of the tire. G WARNING Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the tires. Exceeding the maximum speed for which tires are rated can lead to sudden tire failure, causing loss of vehicle control and possibly resulting in an accident and/or serious personal injury and possible death, for you and for others.

Regardless of the speed rating always observe the speed limits. Drive carefully and adapt your driving style to the traffic conditions. Summer tires Speed rating Index Up to 100 mph (160 km/h) Up to 106 mph (170 km/h) Up to 112 mph (180 km/h) Up to 118 mph (190 km/h) Up to 130 mph (210 km/h) Up to 149 mph (240 km/h) Up to 168 mph (270 km/h) Up to 186 mph (300 km/h) ZR...Y Up to 186 mph (300 km/h) ZR...(..Y) Above 186 mph (300 km/h) Above 149 mph (240 km/h) ZR

Tire labeling 313

The service specifications consist of load bearing index A and speed rating B.

RIf the size description of your tire includes

"ZR" and there are no service specifications, ask the tire manufacturer in order to find out the maximum speed. If a service specification is available, the maximum speed is limited according to the speed rating in the service specification. Example: 245/40 ZR 18 97 Y. In this example, "97 Y" is the service specification. The letter "Y" represents the speed rating and the maximum speed of the tire is limited to 186 mph (300 km/h).

REvery tire that has a maximum speed above 186 mph (300 km/h) must have "ZR" in the size description and the service specification must be given in brackets. Example: 275/40 ZR 18 (99 Y). The speed rating "(Y)" shows that the maximum speed of the tire is above 186 mph (300 km/h). Ask the tire manufacturer to find out the maximum speed. All-weather tires and winter tires Index Q M+S20 Up to 100 mph (160 km/h) T M+S20 Up to 118 mph (190 km/h) H M+S20 Up to 130 mph (210 km/h) V M+S20 Up to 149 mph (240 km/h)

Speed rating

i Not all tires that have the M+S

identification offer the driving characteristics of winter tires. Winter tires have, in addition to the M+S identification, the i snow flake symbol on the tire sidewall. Tires with this identification fulfill the requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Canada (RAC) regarding the tire traction on snow and

314 Tire labeling

have been especially developed for driving on snow.

An electronic speed limiter prevents your vehicle from exceeding the following speeds: RAll vehicles (except AMG vehicles):

130 mph (210 km/h)

RAMG vehicles: 155 mph (250 km/h) RAMG vehicles with increased top speed:

174 mph (280 km/h)

The speed rating of tires mounted at the factory may be higher than the maximum speed that the electronic speed limiter permits. Make sure that your tires have the required speed rating as specified in the "Tires" section (Y page 319), e.g. if you buy new tires. Further information about reading tire data can be obtained from any qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

Load index

i Tire data is vehicle-specific and may deviate from the data in the example.

In addition to the load bearing index, load index : may be imprinted after the letters that identify speed rating B (Y page 312) on the sidewall of the tire.

RIf no specification is given: no text (as in the

example above), represents a standard load (SL) tire

RXL or Extra Load: represents a reinforced

tire

RLight load: represents a light load tire RC, D, E: represents a load range that

depends on the maximum load that the tire can carry at a certain pressure

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 : indicates 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

Definition of terms for tires and loading 315

have a code with two symbols. Retreaded tires have a code with four symbols. Further information about retreaded tires (Y page 294). 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.

Tire characteristics

i Tire data is vehicle-specific and may deviate from the data in the example.

This information describes the tire cord and the number of layers in sidewall : and under the tread ;.

Definition of terms for tires and loading Tire ply composition and material used Describes the number of plies or the number of layers of rubber-coated fabric in the tire

tread and sidewall. These are made of steel, nylon, polyester and other materials.

Bar Metric unit for tire pressure. There are 14.5038 pounds per square inch (psi) to 1 bar; there are 100 kilopascals (kPa) to 1 bar.

DOT (Department of Transportation) DOT marked tires fulfill the requirements of the United States Department of Transportation.

Normal occupant weight The number of occupants the vehicle is designed to seat, multiplied by 68 kilograms (150 lbs).

Uniform Tire Quality Grading Standards A uniform standard to grade the quality of tires with regards to tread quality, tire traction and temperature characteristics. Ratings are determined by tire manufacturers using U.S. government testing procedures. The ratings are molded into the sidewall of the tire.

Recommended tire pressure The recommended tire pressure applies to the tires mounted at the factory. The Tire and Loading Information placard contains the recommended tire pressures for cold tires on a fully loaded vehicle and for the maximum permissible vehicle speed. The tire pressure table contains the recommended tire pressures for cold tires under various operating conditions, i.e. differing load and speed conditions.

316 Definition of terms for tires and loading

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.

Speed rating The 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.

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

Definition of terms for tires and loading 317

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) 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.

Tire pressure of cold tires The tires are cold: Rif the vehicle has been parked without

direct sunlight on the tires for at least three hours and

Rif the vehicle has not been driven more than

1 mile (1.6 km).

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

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 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 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.

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

318 Changing a wheel

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 "Breakdown assistance" section (Y page 279) 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 279). ! 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. 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.

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.

25 Including external oil cooler. 26 Mixed with water or premixed washer fluid with antifreeze protection.

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. However, the concentration of additives in the fuel must be less than 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 main problems of poor fuel quality is the forming of deposits that are created during the gasoline combustion process. Mercedes-Benz recommends that you use fuel brands that have the additives. Deposits may form if you use fuels without additives over a longer period of time. These deposits are most likely to form 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 Carbon deposits may form if the availability of gasoline with relevant additives is insufficient (in certain regions). 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. 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 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.

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 visit 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.

Brake fluid G WARNING Over a period of time, the brake fluid 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 or on the Internet at http://bevo.mercedes-benz.com.

Coolant Important safety notes The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks: Rcorrosion protection Rantifreeze protection Rraising the boiling point The engine cooling system is filled at the factory with coolant that 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 overheating.

If the coolant has antifreeze protection down to -35 ‡ (-37 †), the boiling point of the coolant under operating conditions is approximately 266 ‡ (130 †). Your vehicle has a range of aluminum components. Aluminum components in the engine make it necessary to use antifreeze/ corrosion inhibitor coolant that 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 to 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 filled up with Mercedes-Benz approved products. Therefore, only use MB 325.0 or 326.0 anticorrosion/antifreeze or another Mercedes-Benz approved product of the same specification. 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.

332 Vehicle data

If the coolant level is too low, MB 325.0 or 326.0 anticorrosion/antifreeze 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 1 part MB WinterFit with 2 parts water.
