왔 Rims and Tires ! Only use tires which have been tested and approved for your vehicle by Mercedes-Benz. Tires approved by Mercedes-Benz are developed to provide best possible performance in conjunc- tion with the driving safety systems on your vehi- cle such as ABS or ESP®. Tires specially developed for your vehicle and tested and ap- proved by Mercedes-Benz can be identified by finding the following on the tire’s sidewall: 앫 MO = Mercedes-Benz Original equipment


앫 MOE = Mercedes-Benz Original Extended (tires with limited run-flat characteristics) 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.

i For information on driving with MOExtended tires, see “MOExtended system*” (컄 page 382).

! Using tires other than those approved by Mercedes-Benz 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, exhibit dimen- sional 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 in- flation pressures is located on the driver’s door B-pillar. Some vehicles may have supplemental tire inflation pressure information for driving at high speeds (컄 page 290) or for vehicle loads less than the maximum loaded vehicle condition (컄 page 290).

Technical data Rims and Tires

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 mainte- nance recommendation included with vehicle. i The following pages also list the approved wheel rim and tire sizes for equipping your vehi- cles with winter tires. Winter tires are not avail- able as standard or optional factory equipment, but can be purchased from an authorized Mercedes-Benz Center. Depending on vehicle model and the standard or optional factory-equipped wheel rim/tire config- uration on your vehicle (Appearance Package, Sport Package etc.), equipping your vehicle with winter tires approved for your vehicle model may also require the purchase of two or four wheel rims of the recommended size for use with these winter tires. See an authorized Mercedes-Benz Center for more information.

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 (U.S. vehicles) or FSS (Canada vehicles). For a listing of approved engine oils and oil filters, refer to the Factory Ap- proved Service Products pamphlet, or con- tact an authorized Mercedes-Benz Center.

! Using engine oils and oil filters of specifica- tion other than those expressly required for the Maintenance System (U.S. vehicles) or FSS (Canada vehicles), or changing of oil and oil filter at change intervals longer than those called for by the Maintenance System (U.S. vehicles) or FSS (Canada Vehicles) will result in engine or emission control system damage not covered by the Mercedes-Benz Limited Warranty.


Please follow Maintenance System (U.S. vehicles) or FSS (Canada vehicles) recom- mendations 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.

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 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

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 condi- tions, this moisture content can lead to the formation of bubbles in the system, thus re- ducing the system’s efficiency.

Therefore, the brake fluid must be replaced regularly. Refer to your vehicle’s Mainte- nance Booklet for replacement interval.

Only brake fluid approved by Mercedes-Benz is recommended. An authorized Mercedes-Benz Center will provide you with additional information.

Premium unleaded gasoline


Gasoline is highly flammable and poisonous. It burns violently and can cause serious per- sonal injury.

Never allow sparks, flame or smoking mate- rials near gasoline!

Turn off the engine before refueling

Whenever you are around gasoline, avoid in- haling fumes and skin or clothing contact, extinguish all smoking materials.

Direct skin contact with fuels and the inha- lation of fuel vapors can be damaging to your health.

! To maintain the engine’s durability and per- formance, premium unleaded gasoline must be used. If premium unleaded is not available and low octane fuel is used, follow these precau- tions: 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 acceler-


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

앫 Do not exceed 2/3 of maximum accelerator pedal position if the vehicle is fully loaded or operating in mountainous terrain.

Technical data Fuels, coolants, lubricants, 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: 앫 Warm-up hesitation 앫 Unstable idle 앫 Knocking/pinging 앫 Misfire 앫 Power loss


Technical data Fuels, coolants, lubricants, etc.

In areas where carbon deposits may be encountered due to lack of availability of gasolines which contain these additives, Mercedes-Benz recommends the use of additives approved by us for use on Mercedes-Benz vehicles. Refer to Factory Approved Service Products pamphlet 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 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 listed in the Factory Approved Service Products pamphlet are not covered by the Mercedes-Benz Limited Warranty.


Fuel requirements

Only use premium unleaded fuel: 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.

Flexible Fuel Vehicles (C 230/C 230 Sport only)

Flexible Fuel Vehicles are identified by a label 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 gasoline.


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. 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 before the engine has fully adapted to the different 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 engine behavior.

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 gasoline operation.

i Use of E85 may reduce your driving range.

Maintenance Please inform your authorized Mercedes-Benz Center if you use or have used E85 fuel when your vehicle is deliv- ered for maintenance or repairs.

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 an authorized Mercedes-Benz Center for fur- ther information). Rough idling may also be experienced at such temperatures before the engine is fully warmed up.

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

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


Technical data Fuels, coolants, lubricants, etc.


The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides: 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 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 -22°F (-30°C), the boiling point of the coolant in the pressurized cooling system is reached at approx. 266°F (130°C).


The coolant solution must be used year-round to provide the necessary corro- sion protection and increase boil-over protection. Refer to 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 (see Factory Approved Service Products pamphlet) are used to renew the coolant concentration or bring it back up to the proper level. 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 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, consult an authorized Mercedes-Benz Center.

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 an authorized Mercedes-Benz Center for service.

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 specifi- cally formulated to protect the aluminum parts. Failure to use such anticorrosion/anti- freeze coolant will result in a significantly shortened service life. Therefore, the following product is strongly recommended for use in your vehicle: Mercedes-Benz 325.0 Anticorrosion/Antifreeze Agent.
