Failure to follow these directions will cause damage to the electronic components, and can lead to a battery explosion and severe injury or death.

Never lean over batteries while connecting or jump starting, you might get injured.

Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water, and seek medical help if necessary.

A battery will also produce hydrogen gas, which is flammable and very explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking, etc.

Attempting to jump start a frozen battery can result in it exploding, causing personal injury.

Read all instructions before proceeding.

If the battery is discharged, the engine can be started with jumper cables and the bat- tery of another vehicle. Observe the follow- ing: 앫 Jump starting should only be performed when the engine and catalytic convert- er are cold.

앫 Do not start the engine if the battery is

frozen. Let the battery thaw out first.

앫 Only jump start from batteries with the same voltage rating (12 V). Jump start- ing with a more powerful battery could damage the vehicle's electrical system, which will not be covered by the Mercedes-Benz Limited Warranty.

앫 Use only jumper cables with sufficient-

cross-section and insulated terminal clamps.

앫 Always make sure the jumper cables

are not on or near pulleys, fans or other parts that move when the engine is started or running.

Practical hints Jump starting

Avoid repeated and lengthy starting at- tempts. Do not attempt to start the engine us- ing a battery quick charge unit. If engine does not run after several un- successful starting attempts, have it checked at the nearest authorized Mercedes-Benz Light Truck Center. Excessive unburned fuel generated by repeated failed starting attempts may damage the catalytic converter and may present a fire risk. Make sure the jumper cables do not have loose or missing insulation. Make sure the cable clamps do not touch any other metal part while the other end is still attached to a battery.

Do not tow-start the vehicle.

왔 Towing the vehicle Mercedes-Benz recommends that the vehi- cle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment. This method is pref- erable to other types of towing.

Use flatbed or wheel lift/dolly equip- ment, with key in steering lock turned to position 0. Do not tow with sling-type equipment. Towing with sling-type equipment over bumpy roads will damage radiator and supports. To prevent damage during transport, do not tie down vehicle by its chassis or suspension parts. Use the towing eyes. Switch off the ESP (컄 page 81), tow-away alarm (컄 page 85) and the automatic central locking (컄 page 93).

When circumstances do not permit the recommended towing methods, the vehi- cle may be towed with all wheels on the ground only so far as necessary to have the vehicle moved to a safe location where the recommended towing methods can be em- ployed.

When towing the vehicle with all wheels on the ground, the gear selector lever must be in position N and the key must be in steering lock position 2. When towing the vehicle with all wheels on the ground, the vehicle may be towed only for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). If the vehicle is towed with the front axle raised (observe instructions re- garding flexible drive shaft), the engine must be shut off (key in steering lock position 1). Otherwise, the 4-ETS may become engaged which may cause loss of towing control.

Practical hints Towing the vehicle

To be certain to avoid additional dam- age to the vehicle powertrain, however you should observe the following: 앫 With damage to the front axle

앫 raise front axle 앫 remove flexible drive shaft be- tween rear axle and transfer case

앫 With damage to the rear axle

앫 raise rear axle 앫 tow vehicle with wheel lift or

dolly placed under front wheels 앫 With damage to the transfer case 앫 remove flexible drive shaft to

the drive axles

Always install new self-locking nuts when reinstalling flexible drive shaft.

283

Practical hints Towing the vehicle

Warning!

Warning!

If circumstances require towing the vehicle with all wheels on the ground, always tow with a tow bar if: 앫 the engine will not run 앫 there is a malfunction in the power sup- ply or in the vehicle’s electrical system Prior to towing the vehicle with all wheels on the ground, make certain that the key is in steering lock position 2.

If the key is left in steering lock position 0 for an extended period of time, it can no longer be turned in the switch. In this case, the steering is locked. To unlock, remove key from steering lock and reinsert.

With the engine not running, there is no power assistance for the brake and steering systems. In this case, it is important to keep in mind that a considerably higher degree of effort is necessary to brake and steer the ve- hicle. Adapt your driving accordingly.

To signal turns while being towed with hazard warning flasher in use, turn key in steering lock to position 2 and acti- vate combination switch for left or right turn signal in usual manner – only the selected turn signal will operate. Upon canceling the turn signal, the haz- ard warning flasher will operate again.

The vehicle cannot be started via tow-start.

284

When towing the vehicle with all wheels on the ground, note the following: With the automatic central locking acti- vated and the key in steering lock position 2, the vehicle doors lock if the left front wheel is turning at vehicle speeds of approx. 9 mph (15 km/h) or more. To prevent the vehicle doors from lock- ing, deactivate the automatic central locking (컄 page 93). Towing of the vehicle should only be done using the towing eye. Never at- tach tow cable, tow rope or tow rod to vehicle chassis, frame or suspension parts.

i The gear selector lever will remain locked in position P and the key will not turn in the steering lock if the battery is disconnected or discharged. See notes on the battery (컄 page 278) or on jump starting (컄 page 281). Manual unlocking transmission gear selector lever (컄 page 264).

왔 Rims and tires Use only tires and rims which have been specifically developed for your vehicle and tested and approved by Mercedes-Benz. Other tires and rims can have detrimental effects, such as 앫 poor handling characteristics 앫 increased noise 앫 increased fuel consumption

Moreover, tires and rims not approved by Mercedes-Benz may, under load, ex- hibit dimensional variations and differ- ent tire deformation characteristics that could cause them to come into contact with the vehicle body or axle parts. This may result in damage to the tires or the vehicle.

Technical data Rims and tires

Further information on tires and rims is available at any authorized Mercedes-Benz Light Truck Center. A tire inflation pressure table is located on the fuel filler cap of the vehicle. The tire pressure should be checked regu- larly and should only be adjusted on cold tires. Follow tire manufacturer’s maintenance recommendation includ- ed with vehicle.

Engine oils

Engine oils are specifically tested for their suitability in our engines. Therefore, use only engine oils approved by Mercedes-Benz. Information on approved engine oils is available in the Factory Approved Service Products pamphlet, or at your authorized Mercedes-Benz Light Truck Center.

Always check the oil filler cap (컄 page 221) for important information pertaining to the engine oil needing to meet a specific Mercedes-Benz specifi- cation (e.g. MB 229.5). If such informa- tion is printed on the oil filler cap, only use an engine oil from the list of ap- proved engine oils in the Factory Ap- proved Service Products pamphlet that meets the specification indicated on the oil filler cap.

302

Using engine oils of other specification may cause the FSS to incorrectly deter- mine the next service interval and will result in engine damage not covered by the Mercedes-Benz Limited Warranty.

Engine oil additives

Do not blend oil additives with engine oil. They may damage the engine. Damage or malfunctions resulting from blending oil additives are not covered by the Mercedes-Benz Limited Warranty.

Air conditioning refrigerant

R-134a (HFC) refrigerant and special PAG lubricating oil is used in the air condition- ing system. Never use R-12 (CFC) or mineral-based lu- bricating oil. Otherwise damage to the system will occur.

Brake fluid

During vehicle operation, the boiling point of the brake fluid is continuously reduced through the absorption of moisture from the atmosphere. Under extremely strenu- ous operating conditions, this moisture content can lead to the formation of bub- bles in the system, thus reducing the sys- tem’s efficiency. Therefore, the brake fluid must be re- placed every two years, preferably in the spring. Only brake fluid approved by Mercedes-Benz is recommended. Your au- thorized Mercedes-Benz Light Truck Center will provide you with additional in- formation.

Technical data Fuels, coolants, lubricants etc.

Premium unleaded gasoline

Fuel requirements

Gasoline additives

To maintain the engine’s durability and performance, premium unleaded gaso- line must be used. If premium unleaded is not available and low octane fuel is used, follow these precautions: 앫 Have the fuel tank only partially

filled with unleaded regular and fill up with premium unleaded as soon as possible.

앫 Avoid full throttle driving and abrupt

acceleration.

앫 Do not exceed an engine speed of 3000 rpm if the vehicle is loaded with a light load such as two per- sons and no luggage.

앫 Do not exceed 2/3 of maximum ac- celerator pedal position if the vehi- cle is fully loaded or operating in mountainous terrain.

Use only premium unleaded meeting ASTM standard D 439: 앫 The octane number (posted at the

pump) must be 91 min. It is an average of both the Research (R) octane num- ber and the Motor (M) octane number: (R+M)/2). This is also known as the ANTI-KNOCK INDEX.

Unleaded gasoline containing oxygenates such as ethanol, IPA, IBA and TBA can be used provided the ratio of any one of these oxygenates to gasoline does not exceed 10%; MTBE must not exceed 15%. The ratio of methanol to gasoline must not exceed 3% plus additional cosolvents. Using mixtures of ethanol and methanol is not allowed. Gasohol, which contains 10% ethanol and 90% unleaded gasoline, can be used. These blends must also meet all other fuel requirements, such as resistance to spark knock, boiling range, vapor pressure, etc.

A major concern among engine manufac- turers is carbon build-up caused by gaso- line. Mercedes-Benz recommends only the use of quality gasoline containing additives that prevent the build-up of carbon depos- its. After an extended period of using fuels without such additives, carbon deposits can build up especially on the intake valves and in the combustion area, leading to en- gine performance problems such as: 앫 Warm-up hesitation 앫 Unstable idle 앫 Knocking/pinging 앫 Misfire 앫 Power loss Do not blend other specific fuel additives with fuel. This only results in unnecessary costs and may be harmful to the engine operation.

303

The coolant solution must be used year round to provide the necessary corrosion protection and increase in boil-over pro- tection. Refer to Service Booklet for replacement interval. To provide important corrosion protection, the solution must be at least 45% anticorrosion/antifreeze (equivalent to freeze protection to approx. - 22°F [-30°C]). If you use a solution that is more than 55% anticorrosion/antifreeze (freeze protection to approx. - 49°F [-45°C]), the engine temperature will increase due to the lower heat transfer capability of the so- lution. Therefore, do not use more than this amount of anticorrosion/antifreeze.

If the coolant level is low, water and MB anticorrosion/antifreeze should be used to bring it up to the proper level (have cool- ing system checked for signs of leakage). Please make sure the mixture is in accor- dance with label instructions. The water in the cooling system must meet minimum requirements, which are usually satisfied by normal drinking water. If you are not sure about the water quality, con- sult your authorized Mercedes-Benz Light Truck Center.

Technical data Fuels, coolants, lubricants etc.

Damage or malfunctions resulting from poor fuel quality or from blending specific fuel additives are not covered by the Mercedes-Benz Limited Warranty.

Coolants

The engine coolant is a mixture of water and anticorrosion / antifreeze, which pro- vides: 앫 Corrosion protection 앫 Freeze protection 앫 Boiling protection (by increasing the

boiling point)

The cooling system was filled at the factory with a coolant providing freeze protection to approximately -35°F (-37°C) and corro- sion protection. If the antifreeze mixture is effective to -22°F (-30°C), the boiling point of the cool- ant in the pressurized cooling system is reached at approximately 266°F (130°C).

304

Anticorrosion/antifreeze

Your vehicle contains a number of alumi- num parts. The use of aluminum compo- nents in motor vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifically formulated to protect the aluminum parts. (Failure to use such anticorrosion/antifreeze coolant will result in a significantly shortened service life.) Therefore, the following product is strongly recommended for use in your vehicle: Mercedes-Benz Anticorrosion/Antifreeze agent. Before the start of the winter season (or once a year in hot southern regions), you should have the anticorrosion/antifreeze concentration checked. The coolant is also regularly checked each time you bring your vehicle to your authorized Mercedes-Benz Light Truck Center for service.

Tread wear The tread wear grade is a comparative rat- ing based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For ex- ample, a tire graded 150 would wear one and one-half (1½) times as well on the gov- ernment 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.

Traction The traction grades, from highest to lowest are AA, A, B, and C. Those grades repre- sent the tire’s ability to stop on wet pave- ment as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction perfor- mance.

Warning!

The traction grade assigned to this tire is based on straightahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

Technical data Consumer information 왔 Consumer information This has been prepared as required of all manufacturers of passenger cars under Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the “National Traffic and Motor Vehicle Safety Act of 1966”.

Uniform tire quality grading

Quality grades can be found, where appli- cable, on the tire sidewall between tread shoulder and maximum section width. For example:

Tread wear 200

Traction AA

Temperature

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

308

Warning!

The temperature grade for this tire is estab- lished for a tire that is properly inflated and not overloaded. Excessive speed, underin- flation, or excessive loading, either sepa- rately or in combination, can cause excessive heat build-up and possible tire failure.

Temperature

The temperature grades are A (the high- est), B, and C, representing the tire’s resis- tance 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 tem- perature can cause the material of the tire to degenerate and reduce tire life, and ex- cessive 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 Mo- tor 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.
