Fuses Introduction The electrical fuses in your vehicle serve to switch off malfunctioning power circuits. If a fuse is blown, the components and systems secured by that fuse will stop operating. G Warning! Only use fuses approved by Mercedes-Benz with the specified amperage for the system in question and do not attempt to repair or bridge a blown fuse. Using other than approved fuses or using repaired or bridged fuses may cause an overload leading to a fire, and/or cause damage to electrical components and/or systems. Have the cause determined and remedied by an authorized Mercedes-Benz Center.

! Switch off the vehicle’s internal electrical

functions when you are working on the fuses.

A blown fuse must be replaced by an appropriate spare fuse (recognizable by its color or the fuse rating given on the fuse) of the amperage recommended in the fuse chart. Any Mercedes-Benz Center will be glad to advise you on this subject.

i In case of a blown fuse contact Roadside

Assistance or an authorized Mercedes- Benz Center.

If a newly inserted fuse blows again, have the cause determined and rectified by an authorized Mercedes-Benz Center. A fuse chart is located in the trunk with the vehicle tool kit (Y page 472). The fuse chart explains the fuse allocation and fuse amperages.

Before replacing fuses X Engage the electronic parking brake. X Make sure the automatic transmission is in

park position P. The transmission position indicator in the multifunction display should be on P.

X Switch off all electrical consumers. X Turn off the engine.

Rims and tires Notes ! Only use tires which have been tested and

approved by Mercedes-Benz. Tires approved by Mercedes-Benz are developed to provide best possible performance in conjunction with the driving safety systems on your vehicle such as the ABS or the ESP®. Tires specially developed for your vehicle and tested and approved by Mercedes-Benz can be identified by finding the following on the tire’s sidewall: RMO = Mercedes-Benz Original

equipment tires

Using tires other than those approved by Mercedes-Benz may result in damage that is not covered by the Mercedes-Benz Limited Warranty.

! Using tires other than those approved by

Mercedes-Benz can have detrimental effects, such as Rpoor handling characteristics Rincreased noise Rincreased fuel consumption Moreover, tires and rims not approved by Mercedes-Benz may, under load, exhibit

dimensional variations and different tire deformation characteristics that could cause them to come into contact with the vehicle body or axle parts. Damage to the tires or the vehicle may be the result.

i Further information on tires and rims is

available at any authorized Mercedes-Benz Center. A placard with the recommended tire inflation pressures is located on the driver’s door B-pillar. Some vehicles may have supplemental tire inflation pressure information for driving at high speeds or for vehicle loads less than the maximum loaded vehicle condition. If such information is provided, it can be found on the placard located on the inside of the fuel filler flap. The tire inflation pressure should be checked regularly and should only be adjusted on cold tires. Follow tire manufacturer’s maintenance recommendation included with the vehicle.

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 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.

Fuels, coolants, lubricants etc. 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. 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

26 Restriction: Only SAE 0W-40/SAE 5W-40 engine oils may be used. 580

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

Technical data

Fuels, coolants, lubricants etc.

RMisfire RPower loss In areas where carbon deposits may be encountered due to lack of availability of gasoline which contains these additives, Mercedes-Benz recommends the use of additives approved by us for use on Mercedes-Benz vehicles. Contact an authorized Mercedes-Benz Center or visit www.mbusa.com (USA only) for a listing of approved product(s). Follow directions on 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.

Technical data

Fuels, coolants, lubricants etc. 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 582

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.
