Cleaning and care of the vehicle


Warning! Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the particular container. Always open your vehicle’s doors or windows when cleaning the inside. Never use fluids or solvents that are not designed for cleaning your vehicle.


In operation, your vehicle is subjected to varying external influences which, if gone unchecked, can attack the paintwork as well as the underbody and cause lasting damage. Such damage is caused not only by extreme and varying climatic conditions, but also by air polution, road salt, tar, gravel and stone chipping. Grease and oil, fuel, coolant, brake fluid, bird droppings, insects, tree resins etc. should be removed immediately to avoid paint damage. Frequent washing reduces and/or eliminates the aggressiveness and potency of the above adverse influences.


More frequent washings are necessary to deal with unfavorable conditions; for example, near the ocean, in industrial areas (smoke, exhaust emissions), or during winter operation. You should check your vehicle from time to time for stone chipping or other damage. Any damage should be repaired as soon as possible to prevent the start of corrosion. In doing so, do not neglect the underside of the vehicle. A prerequisite for a thorough check is a washing of the underbody followed by a thorough inspection. Damaged areas need to be reundercoated. Your vehicle has been treated at the factory with a wax- base rustproofing in the body cavities which will last for the lifetime of the vehicle. Post-production treatment is neither necessary nor recommended by Mercedes-Benz because of the possibility of incompatibility between materials used in the production process and others applied later. We have selected car-care products and compiled recommendations which are specially matched to our vehicles and which always reflect the latest technology. You can obtain Mercedes-Benz approved car-care products at your authorized Mercedes-Benz Center.


J_A208.book Seite 303 Donnerstag, 31. Mai 2001 9:35 09


Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with the car-care products recommended here. In such cases it is best to seek aid at your authorized Mercedes-Benz Center. The following topics deal with the cleaning and care of your vehicle and give important “how-to” information as well as references to Mercedes-Benz approved car-care products. Additional information can be found in the booklet titled “Vehicle Care Guide”.


Power washer When using a power washer for cleaning the vehicle always observe manufacturer’s operating instructions.


Caution! Never use a round nozzle to power wash tires. The intense jet of water can result in damage to the tire. Always replace a damaged tire. Always keep the jet of water moving across the surface. Do not aim directly at soft top, electrical parts, electrical connectors, seals, or other rubber parts.


Paintwork, painted body components Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”, normally in 3 to 5 months, depending on climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if paint surface shows signs of dirt embedding (i.e. loss of gloss). Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot. Use the appropriate MB-Touch-Up Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors etc.).

Cleaning and care of the vehicle


304


Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical components and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticorrosion Wax should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bushings and joints should be lubricated. The poly-V-belt and all pulleys should be protected from any wax.


Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.


Vehicle washing Do not use hot water or wash your vehicle in direct sunlight. Use only a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo. Thoroughly spray the vehicle with a diffused jet of water. Direct only a very weak spray towards the ventilation intake. Use plenty of water and rinse the sponge and chamois frequently. Rinse with clear water and thoroughly wipe dry with a chamois. Do not allow cleaning agents to dry on the finish. In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the underbody, do not forget to clean the inner sides of the wheels.


Ornamental moldings For regular cleaning and care of very dirty chrome- plated parts, use a chrome cleaner.


J_A208.book Seite 305 Donnerstag, 31. Mai 2001 9:35 09


Headlamps, taillamps, turn signal lenses Use a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo, with plenty of water. To prevent scratches, never apply strong force and use only a soft, non-scratchy cloth when cleaning the lenses. Do not attempt to wipe dirty lenses with a dry cloth or sponge.


Window cleaning Use a window cleaning solution on all glass surfaces. An automotive glass cleaner is recommended.


Note: For safety reasons, switch off wiper and remove electronic key from steering lock before cleaning the windshield, otherwise the wiper motor can suddenly turn on and cause injury.


Plastic and rubber parts Do not use oil or wax on these parts.


Wiper blade Clean the wiper blade rubber with a clean cloth and detergent solution.


Note: For safety reasons, remove electronic key from steering lock before cleaning the wiper blade, otherwise the wiper motor can suddenly turn on and cause injury.


Light alloy wheels Mercedes-Benz approved Wheel Care should be used for regular cleaning of the light alloy wheels. If possible, clean wheels once a week with Mercedes- Benz approved Wheel Care, using a soft bristle brush and a strong spray of water. Follow instructions on container.


Note: Use only acid-free cleaning materials. The acid could lead to corrosion.

Instrument cluster Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. Wipe with a cloth moistened in lukewarm solution. Do not use scouring agents.


Seat belts The webbing must not be treated with chemical cleaning agents. Use only clear, lukewarm water and soap. Do not dry the webbing at temperatures above 176°F (80°C) or in direct sunlight.


Steering wheel and gear selector lever Wipe with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care.


Warning! Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection.


Cup holder Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. Wipe with a cloth moistened in lukewarm solution. Do not use scouring agents.


Headliner Clean with soft bristle brush, or use a dry-shampoo cleaner in case of excessive dirt.


J_A208.book Seite 307 Donnerstag, 31. Mai 2001 9:35 09


Upholstery Using aftermarket seat covers or wearing clothing that have the tendency to give off coloring (e.g. when wet etc.) may cause the upholstery to become permanently discolored. By lining the seats with a proper intermediate cover, contact-discoloration will be prevented. Leather Upholstery Wipe leather upholstery with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care. Exercise particular care when cleaning perforated leather as its underside should not become wet. MB Tex Upholstery Pour Mercedes-Benz approved Interior Care onto soft lint-free cloth and apply with light pressure.


Hard plastic trim items Pour Mercedes-Benz approved Interior Care onto soft lint-free cloth and apply with light pressure.


Plastic and rubber parts Do not use oil or wax on these parts.


Wind screen Use only water or mild detergent to clean the wind screen.


Rubber weatherstrip The door and windshield header rubber weatherstrip material should be cared for at regular intervals with a silicon-based car care product.

Soft top Clean soft top with soft top raised and locked. Lower the soft top into the storage compartment only if the soft top is completely dry. If the soft top is kept in the storage compartment for a lengthy period, raise it and air out with the windows open about every 4 months.


Dry cleaning: Brush top (always from front to rear) with a soft-bristled brush.


Wet cleaning: Brush the dry top. Wash with a mild detergent and an ample supply of lukewarm water by wiping with a soft- bristled brush or sponge from front to rear. Then rinse thoroughly with clear water. If only parts of the top have been washed, wet the entire top and allow it to air-dry before lowering it into the storage compartment. Do not use sharp-edged instruments for the removal of ice and snow.


Notes: When you run the vehicle through an automatic car wash, never use hot-wax for conservation. Depending on the operation mode of the car wash, there is the possibility of water drops entering the vehicle’s interior. Never use a power washer to clean the soft top, as you may damage the soft top material. Remove bird droppings immediately. The organic acid damages the material and causes the soft top to leak. In general, regular spraying or cleansing with clear water is sufficient to keep the top clean. Wash the top only when heavily soiled. Light colored soft tops should be cleaned frequently to prevent spots and dirt from setting in, which could stain and discolor the soft top material permanently.


Caution! Never use any gasoline, thinner, tar and stain removers, glass cleaner, or similar organic solvents to clean the soft top or wind screen. They will cause damage which is not covered by the Mercedes-Benz Limited Warranty.

Engine oils Engine oils are specifically tested for their suitability in our engines. Therefore, use only engine oils recommended by Mercedes-Benz. Information on recommended brands is available at your authorized Mercedes-Benz Center. Please follow Service Booklet 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 be harmful to the engine operation. Damage or malfunctions resulting from blending oil additives are not covered by the Mercedes-Benz Limited Warranty.


Air conditioner refrigerant R-134a (HFC) refrigerant and special PAG lubricating oil is used in the air conditioner 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 hard operating conditions, this moisture content can lead to the formation of bubbles in the system thus reducing the system’s efficiency. The brake fluid must therefore be replaced every two years, preferably in the spring. It is recommended to use only brake fluid approved by Mercedes-Benz. Your authorized Mercedes-Benz Center will provide you with additional information.

Premium unleaded gasoline


Caution! To maintain the engine’s durability and performance, premium unleaded gasoline must be used. If premium unleaded is not available and low octane fuel is used, follow these precautions: • have the fuel tank filled only partially with unleaded regular and fill up with premium unleaded as soon as possible,


• avoid full throttle driving and abrupt acceleration, • 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,


• do not exceed 2/3 of maximum accelerator pedal


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


Fuel requirements Use only Premium unleaded meeting ASTM standard D 439: The octane number (posted at the pump) must be 91 min. It is an average of both the Research (R) octane number and the Motor (M) octane number: [(R+M)/2]. This is also known as 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 not to 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 the use of only 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: • warm-up hesitation, • unstable idle, • knocking/pinging, • misfire, • power loss. Do not blend other specific fuel additives with fuel. They only result in unnecessary cost, and may be harmful to the engine operation. Damage or malfunctions resulting from poor fuel quality or from blending specific fuel additives are not covered by the Mercedes-Benz Limited Warranty.


Coolants The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides: • corrosion protection, • freeze protection, • 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 approximately 266°F (130°C). The coolant solution must be used year round to provide the necessary corrosion protection and increase in the boil-over protection. You should have it replaced every 3 years. To provide the important corrosion protection, the solution must be at least 45% anticorrosion/antifreeze (equals a 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]),


J_A208.book Seite 323 Donnerstag, 31. Mai 2001 9:35 09


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 anticorrosion/ antifreeze should be used to bring it up to the proper level (have cooling system checked for signs of leakage). The water in the cooling system must meet minimum requirements, which are usually satisfied by normal drinking water. If your are not sure about the water quality, consult your 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: Mercedes-Benz Anticorrosion/antifreeze agent.


Before the start of the winter season (or once a year in the 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.

may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.


Traction The traction grades, from highest to lowest are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.


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.


Consumer information This has been prepared as required of all manufactures of passenger cars under Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the “National Traffic and Motor Vehicle Safety Act of 1966”.


Uniform tire quality grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example:


Tread wear 200


Traction AA


Temperature A


All passenger vehicle tires must conform to federal safety requirements in addition to these grades.


Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and


J_A208.book Seite 325 Donnerstag, 31. Mai 2001 9:35 09


Temperature The temperature grades are A (the highest), B, and C, representing the tire’s resistance 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 temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger vehicle tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.


Warning! The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build up and possible tire failure.
