Operation Maintenance 왔 Maintenance We strongly recommend that you have your vehicle serviced by your authorized Mercedes-Benz Center, in accordance with the Service Booklet at the times called for by the FSS (Flexible Service System). Failure to have the vehicle maintained in accordance with the Service Booklet at the designated times/mileage called for by the FSS may result in vehicle damage not covered by the Mercedes-Benz Limited Warranty. FSS will notify you when your next service is due. Approximately one month before your next service is due, one of the following mes- sages will appear in the multifunction dis- play while you are driving or when you switch on the ignition (example service A): Service A in XXXXX miles (km) Service A in XXX days Service A in X day Service A due now! 296 The type of service due is indicated in the multifunction display: 9 Minor service (A) ´ Major service (B) The interval between services depends on your driving habits. A gentle driving style, moderate engine speeds and the avoidance of short-distance trips will lengthen the interval between services. Clearing the service indicator The service indicator is automatically cleared after 30 seconds. You can also clear it yourself. 왘 Press the reset button on the instru- ment cluster (컄 page 126). Service term exceeded If you have exceeded the suggested ser- vice term, you will see the following mes- sage in the multifunction display: Service A exceeded by XXXXX miles (km) Service A exceeded by XXX days Service A exceeded by X day An acoustic signal will also sound. The Mercedes-Benz Center will reset the service indicator following a completed service. Calling up the service indicator Resetting the service indicator 왘 Switch on ignition. The standard display of the control sys- tem appears (컄 page 129). 왘 Press button k or j on the mul- tifunction steering wheel until FSS indi- cator with the service symbol 9 or ´ and the service deadline appears in the multifunction display. If the battery is disconnected, the days of disconnection will not be included in the count shown by the service indica- tor. To arrive at the true service dead- line, you will need to subtract these days from the days shown in the ser- vice indicator. Do not confuse the service indicator with the engine oil level indicator :. In the event that the service on your vehi- cle is not carried out by an authorized Mercedes-Benz Center, you can reset the service indicator yourself. 왘 Switch on ignition. The standard display of the control sys- tem appears (컄 page 129). 왘 Press button k or j on the mul- tifunction steering wheel until the FSS indicator with the service symbol 9 or ´ and the service deadline ap- pears in the multifunction display. 왘 Press reset button to the left in the in- strument cluster for about three sec- onds. This message appears in the multifunc- tion display: Service interval... To reset: Press reset button for 3 seconds Operation Maintenance 왘 To confirm, press reset button until you hear a signal. The service indicator now displays the reset interval. If the service indicator was inadvertent- ly reset, have a Mercedes-Benz Center correct it. Only reset if the proper service has been performed. Resetting the system without performing proper service as called for by the FSS will cause the FSS to incorrectly determine the next ser- vice interval which will result in engine damage not covered by the Mercedes-Benz Limited Warranty. 297 Operation Vehicle care 왔 Vehicle care Cleaning and care of vehicle Warning! Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the partic- ular container. Always open your vehicle’s doors or windows when cleaning the inside. Never use fluids or solvents that are not de- signed for cleaning your vehicle. While in operation, even while parked, your vehicle is subjected to varying external in- fluences which, if gone unchecked, can at- tack the paintwork as well as the underbody and cause lasting damage. 298 Such damage is caused not only by ex- treme and varying climatic conditions, but also by: 앫 Air pollution 앫 Road salt 앫 Tar 앫 Gravel and stone chipping To avoid paint damage, you should imme- diately remove: 앫 Grease and oil 앫 Fuel 앫 Coolant 앫 Brake fluid 앫 Bird droppings 앫 Insects 앫 Tree resins, etc. Frequent washing reduces and/or elimi- nates the aggressiveness and potency of the above adverse influences. More frequent washings are necessary to deal with unfavorable conditions: 앫 near the ocean 앫 in industrial areas (smoke, exhaust emissions) 앫 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 corrosion. In doing so, do not neglect the underbody of the vehicle. A prerequisite for a thor- ough check is a washing of the underbody followed by a thorough inspection. Dam- aged areas need to be re-undercoated. Your vehicle has been treated at the facto- ry 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 ap- plied later. Operation Vehicle care 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. 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 prod- ucts. Additional information can be found in the booklet “Vehicle Care Guide“. Power washer When using a power washer for cleaning the vehicle, always observe the manufac- turer’s operating instructions. Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended. Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approx. 3 ft (approx. 1 m), the vehicle could be inadvertently locked or unlocked. 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 electrical parts, electrical connec- tors, 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 every three to five months, depending on climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if the paint surface shows signs of embedded dirt (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, vehi- cle doors, etc.). 299 Operation Vehicle care Engine cleaning Prior to cleaning the engine compartment, make sure to protect electrical compo- nents and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticor- rosion Wax, should be applied to the en- gine compartment after every engine cleaning. Before applying, all control link- age bushings and joints should be lubricat- ed. The poly-V-belt and all pulleys should be protected from any wax. 300 Vehicle washing Do not use hot water or wash your vehicle in direct sunlight. Only use a mild car wash detergent, such as Mercedes-Benz ap- proved Car Shampoo. Thoroughly spray the vehicle with a dif- fused 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 dry with a chamois. Do not allow cleaning agents to dry on the finish. Due to the width of the vehicle, fold in out- side mirrors prior to running the vehicle through an automatic car wash to prevent damage to the mirrors. In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the underbody, do not for- get to clean the inner sides of the wheels. Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approx. 3 ft (approx. 1 m), the vehicle could be inadvertently locked or unlocked. Ornamental moldings For regular cleaning and care of very dirty chrome-plated parts, use a chrome clean- er. Headlamps, tail lamps, side markers, 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 only use a soft, non-scratchy cloth when cleaning the lenses. Do not at- tempt to wipe dirty lenses with a dry cloth or sponge. Cleaning the Distronic* system sensor cover Cleaning the Parktronic* system sensors Operation Vehicle care To prevent scratches, never apply strong force and only use a soft, non-scratchy cloth when cleaning the sensor.

Operation Vehicle care Seat belts The webbing must not be treated with chemical cleaning agents. Only use clear, lukewarm water and soap. Do not dry the webbing at temperatures above 176°F (80°C) or in direct sunlight. 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. 303 Operation Vehicle care 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 dis- colored. By lining the seats with a proper intermediate cover, contact-discoloration will be prevented. Nubuck leather upholstery (CLK 55 AMG) The nubuck leather upholstery is treated with a protective coating. Wipe nubuck leather upholstery with damp microfiber cloth to remove dust and other light stains. Carefully dab nubuck leather upholstery with a microfiber cloth to remove oil stains. 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 per- forated leather as its underside should not become wet. Do not use Mercedes-Benz approved Leather Care or any solvents to clean nubuck leather upholstery. Avoid hard scrubbing on nubuck leath- er upholstery. Plastic and rubber parts Do not use oil or wax on these parts. Wood trims Dampen cloth using water and use damp cloth to clean wood trims in your vehicle. Do not use solvents like tar remover or wheel cleaner nor polishes or waxes as these may be abrasive. 304 Practical hints What to do if …? Where will I find...?
