the environment if disposed of improperly. Large 12 volt storage batteries contain lead. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to accept old batteries for recycling.

Failure to follow these instructions can re- sult in severe injury or death.

Observe all safety instructions and precau- tions when handling automotive batteries (컄 page 235). Never lean over batteries while connecting, 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 explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking, etc.

Never charge a battery while still installed in the vehicle. Gases may escape during charg- ing and cause explosions that may result in paint damage, corrosion or personal injury.

Have the battery removed at a Mercedes-Benz Light Truck Center.

Have the battery checked regularly by an authorized Mercedes-Benz Light Truck Center. Refer to Service Booklet for mainte- nance intervals or contact your autho- rized Mercedes-Benz Light Truck Center for further information.

If you charge the battery yourself, make sure to comply with the operating instruc- tions for your battery charger.

왔 Jump starting

Warning!

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 use 12 volt battery to jump start your vehicle. Jump starting with a more powerful battery could damage the ve- hicle’s electrical system, which will not be covered by the Mercedes-Benz Lim- ited 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 oth- er parts that move when an 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.

왘 Start the engine of the disabled vehi-

cle.

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 SmartKey in starter switch 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 79), tow-away alarm (컄 page 83) and the automatic central locking (컄 page 133).

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 Smart- Key must be in starter switch 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 one axle raised (observe instructions regarding flexible drive shaft and propeller shafts), the engine must be shut off (SmartKey in starter switch position 1). Otherwise, the 4-ETS may become en- gaged which may cause loss of towing control.

Practical hints Towing the vehicle

Do not tow-start the vehicle.

Warning!

Prior to towing the vehicle with all wheels on the ground, make certain that the SmartKey is in starter switch position 2.

If the SmartKey is left in the starter switch 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, re- move SmartKey from starter switch and re- insert.

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 as that will be necessary to adequately con- trol the towed vehicle.

315

i To signal turns while being towed with hazard warning flasher in use, turn SmartKey in starter switch to position 2 and activate combination switch for left or right turn signal in usu- al manner – only the selected turn sig- nal will operate. Upon canceling the turn signal, the haz- ard warning flasher will operate again.

When towing the vehicle with all wheels on the ground, note the following: With the automatic central locking acti- vated and the SmartKey in starter switch position 2, the vehicle doors lock if the wheels are 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 133). 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.

Practical hints Towing the vehicle

Warning!

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.

The gear selector lever will remain locked in position P and the SmartKey will not turn in the starter switch if the battery is disconnected or discharged. See notes on the battery (컄 page 311) or on jump starting (컄 page 313). Manually unlocking transmission gear selector lever (컄 page 290).

316

Transporting the vehicle

When transporting the vehicle, you can use the towing eyes for pulling the vehicle onto a trailer or transporter. 왘 Move the gear selector lever to posi-

tion N.

왘 Shift the transfer case to neutral posi-

tion N.

왘 To avoid damaging the vehicle, it should only be tied down on the wheels/wheel rims, not on chassis components such as the transverse link or trailing arm.

Towing the vehicle - various problem scenarios

When removing drive shaft, place M10 nuts on bolts as distance sleeves and tighten using M8 nuts. Always install new self-locking nuts when reinstalling the drive shaft.

왘 Comply with all towing information

(컄 page 315).

In case of engine damage, transmission damage or malfunctions in electrical equipment 왘 Move the gear selector lever to posi-

tion N.

왘 Shift the transfer case to neutral posi-

tion N.

Practical hints Towing the vehicle

In case of transfer case damage or for towing vehicle distances exceeding 30 miles (50 km) The propeller shafts to the drive axles must be removed.

In case of front axle damage Raise the front axle when towing. The pro- peller shaft between the rear axle and the transfer case must be removed.

In case of rear axle damage When the rear axle is raised, the vehicle can only be towed with a wheel lift or a dol- ly placed under its front wheels.

Freeing a stranded vehicle

Freeing a stranded vehicle, on which the wheels are dug into sand or mud, should be done with the greatest of care, especial- ly if the vehicle is heavily loaded. Avoid pulling the vehicle jerkily or diago- nally, since it could result in damage to the chassis alignment. Never try to free a vehicle that is still cou- pled to a trailer. If possible, a vehicle equipped with trailer hitch receiver should be pulled backward in its own previously made tracks.

In the front, the towing eye is located on the driver’s side under the bumper.

In the rear, the towing eye is located on the driver’s side under the bumper.

Engine oils

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

Always check the oil filler cap (컄 page 232) for important informa- tion pertaining to the engine oil need- ing to meet a specific Mercedes-Benz specification (e.g. MB 229.5). If such information is printed on the oil filler cap, only use an engine oil from the list of approved engine oils in the Factory Approved Service Products pamphlet that meets the specification indicated on the oil filler cap.

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.

Please follow the FSS and Service Booklet recommendations for scheduled oil chang- es. Failure to do so could result in engine damage not covered by the Mercedes-Benz Limited Warranty.

334

Engine oil additives

Brake fluid

Premium unleaded gasoline

Technical data Fuels, coolants, lubricants, etc.

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.

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 Cen- ter will provide you with additional information.

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.

335

Technical data Fuels, coolants, lubricants, etc.

Fuel requirements

Gasoline additives

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.

336

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 cost and may be harmful to the engine op- eration.

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).

The coolant solution must be used year round to provide the necessary corrosion protection and increase in the boil-over protection. Refer to Service Booklet for re- placement interval. To provide important corrosion protection, the solution must be at least 45% anticor- rosion/antifreeze (equivalent to freeze protection to approx. - 22°F [-30°C]). If you use a solution that is more than 55% anticorrosion/antifreeze (freeze protec- tion to approx. - 49°F [-45°C]), the engine temperature will increase due to the lower heat transfer capability of the solution. 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.

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 specifical- ly formulated to protect the aluminum parts. (Failure to use such anticorro- sion/antifreeze coolant will result in a sig- nificantly shortened service life.) Therefore, the following product is strongly recommended for use in your vehicle: Mercedes-Benz anticorrosion/antifreeze agent.

337

Technical data Fuels, coolants, lubricants, etc.

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 (11⁄2) 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.

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 straight ahead 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 Ti- tle 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.

340

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. 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 perfor- mance on the laboratory test wheel than the minimum required by law.
