Practical hints Flat tire

Warning!

Follow recommended inflation pressures.

Do not overinflate tires. Overinflated tires can result in sudden deflation (blowout) be- cause they are more likely to become punc- tured or damaged by road debris, potholes, etc.

Do not underinflate tires. Underinfalted tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated.

Do not overload the tires by exceeding the specified vehicle capacity weight (as indicat- ed by the label on the driver’s door latch post). Overloading the tires can overheat them, possibly causing a blowout.

왘 Detach the electric air pump. 왘 Store the electrical plug and the air

hose behind the flap and place the air pump back in the trunk.

Practical hints Jump starting 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.

310

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 cabels

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

Jump starting may only be performed on the battery installed in the engine compartment. 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 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.

Warning!

Keep flames or sparks away from battery. Do not smoke.

Observe all safety instructions and precau- tions when handling automotive batteries (컄 page 242).

The battery is located in the engine com- partment on the right hand side. The terminals for jump starting are located in front of the battery. 왘 Make sure the two vehicles do not

touch.

왘 Turn off the engine. On both vehicles: 왘 Turn off all electrical consumers. 왘 Apply parking brake. 왘 Shift gear selector lever to position P

(manual transmission to Neutral).

Practical hints Jump starting

왘 Start engine of the vehicle with the

charged battery and run at idle speed. 왘 Connect negative terminal 3 of the charged battery with negative under hood terminal 4 in front of the dis- charged battery with the jumper ca- bles. Clamp cable to charged battery 3 first.

왘 Start the engine of the disabled vehi-

cle.

Now you can turn on the electrical con- sumers. Do not turn on the lights under any circumstances.

311

Practical hints Jump starting

왘 Remove the jumper cables first from

negative terminals 3 and 4 and then from positive terminals 1 and 2.

You can now turn on the lights. 왘 Have the battery checked at the

nearest authorized Mercedes-Benz Center.

Vehicles with automatic transmission: Do not tow-start the vehicle.

312

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

Vehicles with automatic transmission: 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 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. Switch off the tow-away alarm (컄 page 79) and deactivate the auto- matic central locking (컄 page 129).

Practical hints Towing the vehicle

If the vehicle is towed with the front axle raised, the engine must be shut off (SmartKey in starter switch position 0 or 1). Otherwise, the ESP will immedi- ately be engaged and will apply the rear wheel brakes. When towing the vehicle with all wheels on the ground, the gear selector lever must be in position N (manual trans- mission: gears disengaged) and the SmartKey must be in starter switch position 2. When towing the vehicle with all wheels on the ground or the front axle raised, the vehicle may be towed only for dis- tances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h).

313

Practical hints Towing the vehicle

To be certain to avoid a possibility of damage to the transmission, however, we recommend the drive shaft be dis- connected at the rear axle drive flange for any towing beyond a short tow to a nearby garage.

314

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

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

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 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.

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.

When towing the vehicle with all wheels on the ground, please note the follow- ing: With the automatic central locking acti- vated and the SmartKey in starter switch position 2, the vehicle doors lock if the left front wheel as well as the right rear wheel are turning at vehicle speeds of approx. 9 mph (15 km/h) or more. Switch off the tow-away alarm (컄 page 79). To prevent the vehicle doors from lock- ing, deactivate the automatic central locking (컄 page 129). Towing of the vehicle should only be done using the properly installed tow- ing eye bolt. Never attach tow cable, tow rope or tow rod to vehicle chassis, frame or suspension parts.

Practical hints Towing the vehicle

If the battery is disconnected or dis- charged 앫 the SmartKey will not turn in the starter switch. See notes on the battery (컄 page 307) or on jump starting (컄 page 310).

앫 the gear selector lever will remain locked in position P. See notes on manual unlocking of gear selector lever (컄 page 291).

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 FSS recommendations for scheduled oil changes. Failure to do so could 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 Center will pro- vide you with additional information.

Premium unleaded gasoline

Fuel requirements

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.

Flexible Fuel Vehicles (identified by a label reading Premium gasoline or E85 only! on fuel filler flap) are de- signed to operate on premium unlead- ed gasoline or Ethanol fuel (E85), or any mixture of these two. See notes on Flexible Fuel Vehicles (컄 page 334).

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.

Technical data Fuels, coolants, lubricants, etc.

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.

333

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

Flexible Fuel Vehicles

Flexible Fuel Vehicles are identified by a la- bel reading Premium gasoline or E85 only! on fuel filler flap). These vehicles are designed to operate on premium unleaded gasoline or Ethanol fuel (E85), or on any mixture of these two. Ethanol fuel (E85) is a mixture of approxi- mately 85% Ethanol and 15% unleaded gas- oline.

Warning!

Ethanol fuel (E85) and its fumes are highly flammable, poisonous and burn easily. Etha- nol fuel can cause serious injuries if ignited or if you come into contact with it or inhale fumes of it. Avoid inhalation of Ethanol fumes and skin contact with Ethanol. Extin- guish all open flames before fueling. Never smoke or create sparks close to Ethanol.

Switching fuels For best performance and driveability it is recommended to use either one or the oth- er fuel. A refueling pattern that alternates between the two different fuels should be avoided if possible.

Technical data Fuels, coolants, lubricants, etc.

Gasoline additives

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 any specific fuel additives with fuel. This only results in unnecessary cost and may be harmful to engine opera- tion.

334

Technical data Fuels, coolants, lubricants, etc.

Cold weather performance It is possible that starting times will signif- icantly increase at temperatures below 32°F (0°C). At low temperatures the use of a block heater is recommended (see your authorized Mercedes-Benz Center for further information). Rough idling may also be experienced at such temperatures be- fore the engine is fully warmed up.

Cruising range E85 fuel contains less energy per gallon than gasoline. To ensure that engine per- formance with Ethanol fuel is similar to that when using gasoline, the engine must burn more Ethanol fuel. As a result, it is to be expected that the fuel consumption will increase when using E85 compared to gas- oline operation.

E85 fuel is unsuitable for use when am- bient temperatures fall below 14°F (-10°C).

Use of E85 may reduce your driving range.

Hot weather performance At ambient temperatures above 95°F (35°C) start times may increase and be ac- companied by a rough idle following the start.

Maintenance Please inform your Mercedes-Benz Center if you use or have used E85 fuel when your vehicle is delivered for maintenance or re- pairs.

When switching fuels, make sure: 앫 Fuel level is below half full. 앫 Fuel level is above reserve (reserve

warning lamp is not lit).

앫 Amount of added fuel is more than

5 gallons (20 liters).

앫 Ignition is off during refill. 앫 Immediately after refueling engine is started and operated for at least five minutes.

These precautions and recommendations are supposed to prevent any difficulties when starting and operating the engine which otherwise may be experienced be- fore the engine has fully adapted to the dif- ferent fuel. If in spite of these recommendations the engine does not perform properly, adding more gasoline (at least 3 gallons [12 liters]) to the fuel may improve the en- gine behavior.

335

Technical data Fuels, coolants, lubricants, etc.

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 -22°F (-30°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).

336

The coolant solution must be used year-round to provide the necessary corro- sion protection and increase boil-over pro- tection. Refer to Service Booklet for replacement interval. Coolant system design and coolant used stipulate the replacement interval. The replacement interval published in the Ser- vice Booklet is only applicable if MB 325.0 anticorrosion/antifreeze solution or other Mercedes-Benz approved products of equal specification (see Factory Approved Service Products pamphlet) are used to re- new the coolant concentration or bring it back up to the proper level. 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 325.0 anticorrosion/antifreeze should be used to bring it up to the proper level (have cooling system checked for signs of leakage). Please make sure the mixture is in accordance 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 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 325.0 Anticorrosion/Anti- freeze 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 Center for service.

왔 Consumer information The following text is published as required of all manufacturers of passenger cars un- der Title 49, Code of U.S. Federal Regula- tions, 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.

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.

Technical data Consumer information

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.

339

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.

Technical data Consumer information

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.
