2011 Mercedes-benz G Class Owners Manual

(680 kg) - 150 lbs (68 kg) = 1350 lbs (612 kg)

The higher the weight of all the occupants, the smaller the maximum load for luggage. Further information can be found under "trailer load/noseweight" (Y page 260).

trailer load/noseweight is usually approximately 10% of the gross weight of the trailer and its load. Only use a trailer coupling that has been approved for your vehicle by Mercedes-Benz. Comply with the manufacturer's operating instructions for operation, care and maintenance.

Maximum tire load

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 of the vehicle (Y page 256). 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 The trailer load/noseweight affects the gross weight of the vehicle. If a trailer is attached, the trailer load/noseweight is included in the load along with occupants and luggage. The

Uniform Tire Quality Grading Standards Overview of Tire Quality Grading Standards

The Uniform Tire Quality Grading Standards are U.S. government specifications. Their purpose is to provide drivers with uniform reliable information on tire performance data. Tire manufacturers have to grade tires using three performance factors: tread wear :, tire traction ;, and heat resistance =. All tires sold in North America are provided with the corresponding quality grading markings

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 track. For example, a tire graded 150 would wear one and one-half times as well on the government test track 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

262 Tire labeling

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 tread depth of 1/6 in (4 mm) for all four winter tires (Y page 248) to maintain normal driving characteristics in winter. Winter tires can reduce the braking distance on snow covered surfaces in comparison to summer tires. The braking distance is still much further than on surfaces that are not icy or covered with 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.

Tire labeling Overview of tire labeling The following markings are on the tire in addition to the tire name (sales designation) and the manufacturer's name:

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

Tire labeling 263

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 ratio between the tire height and tire width and is shown as a percentage. 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 that 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.

264 Tire labeling

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 260). For further information on the load bearing index, see Load index (Y page 265). Speed index: speed index 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 index, always observe the speed limits. Drive carefully and adapt your driving style to the traffic conditions. Summer tires Index ZR...Y

ROptionally, tires with a maximum speed

rating of more than 149 mph (240 km/h) may have "ZR" in the size description depending on the manufacturer (e.g. 245/40 ZR 18). The service specification is made up of load bearing index A and speed index 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 index 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 index and the maximum speed of the tire is limited to 186 mph (300 km/h).

REvery tire that has a maximum speed rating

of more than 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 index "(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.

i Not all tires that have the M+S

identification offer the driving characteristics of winter tires. In addition to the M+S marking, winter tires also have the i snowflake symbol on the tire wall. Tires with this marking fulfill the requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Canada (RAC) regarding the tire traction on snow and have been especially developed for driving on snow.

An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h). The speed index 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 index as specified in the "tires" section (Y page 272), 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.

266 Definitions for tires and loading

Characteristics of the tire

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 have a code with two symbols. Retreaded tires have a code with four symbols. Further information about retreaded tires (Y page 246). 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.

accessories, the maximum load and the weight of the optional equipment installed at the factory.

PSI (pounds per square inch) Standard unit of measurement for tire pressure.

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.

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

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

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 permissible tire pressure Maximum permissible tire pressure for one tire.

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

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

Changing a wheel

269

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 232) 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 no warranty book is available, the tires should be rotated every 3000 to 6000 miles (5000 to 10000 km), or earlier if tire wear

270 Wheel and tire combinations

requires. 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 253) if necessary. Information on changing a wheel and mounting the spare wheel (Y page 232). ! On vehicles installed with a tire pressure

monitor, electronic components are located in the wheel. Tire-mounting tools should not be applied in the area of the valve, as 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 install 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 feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the road. Inspect the tires and the vehicle underbody for possible damage. If the vehicle appears unsafe, have the vehicle towed to the nearest

authorized Mercedes-Benz Center or tire dealer for repairs. 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 control systems, such as ABS or ESP®, and are marked as follows: RMO = Mercedes-Benz Original 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.

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

i The following pages contain information

on approved wheels and tire sizes for equipping your vehicle with winter tires. Winter tires are not available at the factory as standard equipment or optional extras. If you wish to fit approved winter tires to your vehicle, wheels of appropriate size may also be required as the sizes of the approved winter tires may differ from those of the original tires. This is dependent on the model and the equipment installed at the factory. Wheels and tires as well as additional information are available from a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

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.

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

278 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 premium-grade unleaded gasoline is unavailable and regular gasoline is used, observe the following precautions: Ronly fill the fuel tank to half full with

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

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

Rwhen the vehicle is fully loaded or being operated in mountainous terrain, do not depress the accelerator pedal further than 2/3 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 that have the additives which prevent the build up of carbon deposits. If you use fuels without these additives for a longer 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 carbon deposits can build up due to 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 visit http://www.mbusa.com (USA only) to view a list of approved products. Observe the instructions for use in the product description.

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. Contact an authorized Mercedes-Benz Center or visit http://www.mbusa.com (USA only) to view a list of approved engine oils and oil filters. ! 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.

Mercedes-Benz recommends MOBIL OIL. The table shows which engines oil have been approved for your vehicle. Model

Additives ! Do not use additives in 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 to observe 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.

i MB Approval is indicated on the oil

bottles.

280 Service products and capacities

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. You could otherwise damage the engine. 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. 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 Mercedes-Benz approved products of the same specification can be obtained at any authorized Mercedes- Benz Center or on the Internet at http://bevo.mercedes-benz.com. The coolant is checked at every service date at an authorized Mercedes-Benz Center.
