ì™” Towing the vehicle Mercedes-Benz recommends that the vehicle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment. This method is preferable to other types of towing.

Use flatbed or wheel lift/dolly equip- ment with the SmartKey in the 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 91) and deactivate the auto- matic central locking (컄 page 153).

When circumstances do not permit the recommended towing methods, the vehicle may be towed with all wheels on the ground or front wheels raised (except vehicles with 4MATIC) 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 and/or 4MATIC: Do not tow-start the vehicle.

Vehicles with 4MATIC: Do not tow with one axle raised. Doing so could damage the transfer case, which is not covered by the Mercedes-Benz Limited Warranty. All wheels must be on or off the ground. Observe instructions for towing the vehicle with all wheels on the ground.

Practical hints Towing the vehicle

If the vehicle is towed with the front axle raised (not permissible for vehicles with 4MATIC), the engine must be shut off (SmartKey in starter switch position 0 or 1). Otherwise the ESP will immediately 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 distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h).

409

Practical hints Towing the vehicle

To be certain to avoid a possibility of damage to the drivetrain, however, we recommend the drive shaft be discon- nected at the rear axle drive flange (vehicles with 4MATIC: disconnected at the front and rear axle drive flanges) for any towing beyond a short tow to a nearby garage.

410

To signal turns while being towed with the hazard warning flasher in use, switch on ignition and activate the combination switch for the left or right turn signal 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 supply or in the vehicle’s electrical system

as that will be necessary to adequately control the towed vehicle.

Prior to towing the vehicle with all wheels on the ground, make sure 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, remove SmartKey from starter switch and reinsert.

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 following: With the automatic central locking activated 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 91). To prevent the vehicle doors from locking, deactivate the automatic central locking (컄 page 153). Towing of the vehicle should only be done using the properly installed towing 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 discharged 앫 the SmartKey will not turn in the starter switch. For more informa- tion, see “Battery” (컄 page 404) and “Jump starting” (컄 page 407). 앫 the gear selector lever will remain locked in position P. For informa- tion on manually unlocking the transmission gear selector lever see (컄 page 386).

Technical data Rims and Tires

Only use tires and rims which have been specifically developed for your vehicle and tested and approved by Mercedes-Benz. Other tires and rims can have detrimental effects, such as ì•« poor handling characteristics ì•« increased noise ì•« increased fuel consumption

Moreover, tires and rims not approved by Mercedes-Benz may, under load, exhibit dimensional variations and different tire deformation characteris- tics 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.

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 (컄 page 314) or for vehicle loads less than the maximum loaded vehicle con- dition. 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 recom- mendation included with vehicle.

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 Approved Service Products pamphlet, or contact an authorized Mercedes-Benz Center. Using engine oils and oil filters of specification 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 damage not covered by the Mercedes-Benz Limited Warranty.

Please follow Maintenance System (U.S. vehicles) or FSS (Canada vehicles) recommendations for scheduled oil changes. Failure to do so will 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 are used in the air conditioning system. Never use R-12 (CFC) or mineral-based lubricating oil. Otherwise damage to the system will occur.

Technical data Fuels, coolants, lubricants, etc.

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 bubbles in the system, thus reducing the system’s efficiency. Therefore, the brake fluid must be replaced every two years, preferably in the spring. Only brake fluid approved by Mercedes-Benz is recommended. Your authorized Mercedes-Benz Center will provide you with additional information.

433

Technical data Fuels, coolants, lubricants, etc.

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.

ì•« Avoid full throttle driving and abrupt

acceleration.

ì•« 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.

ì•« Do not exceed 2/3 of maximum accelerator pedal position if the vehicle 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 designed to operate on premium unleaded gasoline or ethanol fuel (E85) or any mixture of these two. For more information, see “Flexible Fuel Vehicles” (컄 page 435).

Only use premium unleaded fuel: ì•« 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.

434

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.

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: ì•« Warm-up hesitation ì•« Unstable idle ì•« Knocking/pinging ì•« Misfire ì•« Power loss

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 any specific 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.

Technical data Fuels, coolants, lubricants, etc.

Flexible Fuel Vehicles

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 approximately 85% ethanol and 15% unleaded gasoline.

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.

435

Technical data Fuels, coolants, lubricants, etc.

Switching fuels For best performance and driveability it is recommended to use either one or the other fuel. A refueling pattern that alternates between the two different fuels should be avoided if possible. When switching fuels, make sure: ì•« Fuel level is below half full. ì•« Fuel level is above reserve (fuel reserve

warning lamp is not lit).

ì•« Amount of added fuel is more than

5 gallons (20 liters).

ì•« Ignition is off during refill. ì•« 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.

436

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.

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.

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 (Canada only) is recommended (see an authorized Mercedes-Benz Center for further 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).

Cruising range E85 fuel contains less energy per gallon than gasoline. To make sure that engine performance 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.

Use of E85 may reduce your driving range.

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

Coolants

The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides: ì•« Corrosion protection ì•« Freeze protection ì•« 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. 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)].

Technical data Fuels, coolants, lubricants, etc.

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.

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.

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.
