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.

If the battery is discharged, the engine can be started with jumper cables and the fully charged battery of another vehicle or an equivalent starter pack. Observe the following: RAccess to the battery is not possible on all vehicles. If you cannot access the battery of the other vehicle, provide jump start power by an external battery or starter pack.

RJump starting should only be performed when the engine and catalytic converter are cold.

RDo not jump start the engine or charge the

battery if the battery is frozen. Let the battery thaw out first.

ROnly jump start from batteries with the

same voltage rating (12 V). Jump starting with a more powerful battery could damage the vehicle’s electrical system. Such damage will not be covered by the Mercedes-Benz Limited Warranty.

ROnly use jumper cables with sufficient

cross-section and insulated terminal clamps.

RAlways make sure the jumper cables are not on or near pulleys, fans or other parts that move when an engine is started or running.

282 Towing the vehicle

using flatbed or appropriate wheel lift/dolly equipment. This method is preferable to other types of towing. ! To prevent damage during transport, do

not tie down vehicle by its chassis or suspension parts.

If circumstances do not permit the recommended towing methods, the vehicle may be towed with all wheels on the ground or one axle raised only so far as necessary to have the vehicle moved to a safe location where the recommended towing methods can be employed. ! Before towing the vehicle observe the

following instructions: RDo not tow-start the vehicle. You could

otherwise seriously damage the automatic transmission which is not covered by the Mercedes-Benz Limited Warranty.

RDo not tow with sling-type equipment. Towing with sling-type equipment over bumpy roads will damage radiator and supports.

RTowing of the vehicle should only be

done using the properly installed towing eye bolt. Never attach a tow cable, tow rope or tow rod to the vehicle chassis, frame or suspension parts.

G 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 vehicle. Adapt your driving accordingly.

! Avoid pulling the vehicle abruptly or

diagonally, since it could result in damage to the chassis alignment.

! Do not use the towing eye bolt for

recovery, as this could damage the vehicle. If in doubt, recover the vehicle with a crane.

i If the battery is disconnected or

discharged Rthe SmartKey will not turn in the starter

switch

Rthe automatic transmission will remain in

park position P

Approved engine oils Engine oils are specifically tested for their suitability in our engines and durability for our service intervals. Therefore, only use approved engine oils and oil filters required for vehicles with the Maintenance System. For a listing of approved engine oils and oil filters, contact an authorized Mercedes-Benz Center or visit www.mbusa.com (USA only). ! Using engine oils and oil filters of a

specification other than those expressly required for the Maintenance System, or changing of oil and oil filter at change intervals longer than those called for by the Maintenance System will result in engine or emission control system damage not covered by the Mercedes-Benz Limited Warranty. Please follow Maintenance System recommendations for scheduled oil changes. Failure to do so will result in engine or emission control system damage not covered by the Mercedes-Benz Limited Warranty.

Mercedes-Benz recommends MOBIL OIL. Use the table below to determine the MB sheet number. Model

Viscosity grades for engine oils Using the chart below, select oil viscosity according to the lowest air temperature expected before the next oil change.

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 R134a (HFC) refrigerant and special PAG lubricating oil are used in the air conditioning system. ! Never use R 12 (CFC) or mineral-based lubricating oil. Otherwise damage to the system will occur.

Brake fluid G Warning! During vehicle operation, the boiling point of the brake fluid is continuously reduced through the absorption of moisture from the atmosphere.

36 Restriction: Only SAE 0W-40/SAE 5W-40 engine oils may be used.

Under extremely strenuous operating conditions, this moisture content can lead to the formation of bubbles in the system, thus reducing the system’s efficiency. Therefore, the brake fluid must be replaced regularly. Refer to your vehicle’s Maintenance Booklet for replacement interval. Only brake fluid approved by Mercedes-Benz is recommended. Any authorized Mercedes- Benz Center will provide you with additional information.

Premium unleaded gasoline 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. Extinguish all smoking materials. Direct skin contact with fuels and the inhalation of fuel vapors are damaging your health.

! To maintain the engine’s durability and performance, premium unleaded gasoline must be used. If premium unleaded gasoline is not available and low octane gasoline is used, follow these precautions: RHave the fuel tank only partially filled

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

RAvoid full throttle driving and abrupt

acceleration.

RDo not exceed an engine speed of

3 000 rpm if the vehicle is loaded with a

light load such as two persons and no luggage.

RDo not exceed 2/3 of maximum

accelerator pedal position if the vehicle is fully loaded or operating in mountainous terrain.

Fuel requirements Only use premium unleaded gasoline. The octane number (posted at the pump) must be 91 min. It is an average of both the Research Octane Number (RON) and the Motor Octane Number (MON): (RON+MON)/2. This is also known as the ANTI-KNOCK INDEX. Reformulated gasolines (RFG) and/or unleaded gasoline containing oxygenates such as ethanol, TAME, ETBE, 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.

Gasoline additives A major concern among engine manufacturers is carbon build-up caused by gasoline. Mercedes-Benz recommends only the use of quality gasoline containing additives that prevent the build-up of carbon deposits.

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 engine performance problems such as: RWarm-up hesitation RUnstable idle RKnocking/pinging RMisfire RPower loss In areas where carbon deposits may be encountered due to lack of availability of gasoline which contains these additives, the use of Mercedes-Benz approved additives is recommended. Contact an authorized Mercedes-Benz Center or visit www.mbusa.com (USA only) for a listing of approved products. Follow directions on the product label. Do not blend other fuel additives with fuel. This only results in unnecessary cost and may be harmful to the engine operation. ! Damage or malfunction resulting from

poor fuel quality or from blending additional fuel additives other than those tested and approved by us for use on Mercedes-Benz vehicles are not covered by the Mercedes- Benz Limited Warranty or by any pre-owned or Extended Limited Warranties.

Coolants The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides: RCorrosion protection RFreeze protection RBoiling protection (by increasing the boiling

point)

The cooling system was filled at the factory with a coolant providing freeze protection to approximately -35‡ (-37†) and corrosion protection.

! Add premixed coolant solution only.

Adding water and MB 325.0 Anticorrosion/ Antifreeze separately from each other, could cause engine damage not covered by the Mercedes-Benz Limited Warranty.

If the antifreeze mixture is effective to -35‡ (-37†), the boiling point of the coolant in the pressurized cooling system is reached at approximately 266‡ (130†). The coolant solution must be used year round to provide the necessary corrosion protection and increase boil-over protection. Refer to the Maintenance Booklet for replacement interval. Coolant system design and coolant used determine the replacement interval. The replacement interval published in the Maintenance Booklet is only applicable if MB 325.0 Anticorrosion/Antifreeze solution or other Mercedes-Benz approved products of equal specification are used to renew the coolant concentration or bring it back up to the proper level. For information on other Mercedes-Benz approved products of equal specification, contact an authorized Mercedes-Benz Center or visit www.mbusa.com (USA only). To provide important corrosion protection, the solution must be at least 50% anticorrosion/antifreeze (equivalent to freeze protection to approximately -35‡ [-37†]). If you use a solution that is more than 55% anticorrosion/antifreeze (freeze protection to approximately -49‡ [-45†]), 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, contact an authorized Mercedes-Benz Center.

Anticorrosion/antifreeze Your vehicle contains a number of aluminum parts. The use of aluminum components 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: MB 325.0 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 an authorized Mercedes-Benz Center for service.
