Care can result in water penetration. Follow the operating instructions for the high-pressure cleaning jets.< When using high-pressure cleaning jets, do not remain in one place for a long time and be sure to maintain a distance of at least 12 in/30 cm from sensors, e.g. Park Distance Control sensors or radar sensors.< Convertible top care The appearance and service life of the convertible top depend on proper care and operation. Please follow these instructions: > Never stow the convertible top in the convertible top compartment when it is wet or frozen, since this can cause water marks, mildew stains, and scuff marks. > Remove water marks on the headliner with a microfiber cloth and interior cleanser. > When parking for long intervals in enclosed spaces, make sure there is sufficient ventilation. > Remove bird droppings immediately because their caustic properties have a corrosive effect on the convertible top and can damage the rubber seals. Do not use stain remover, paint thinner, solvents, gasoline, or the like to remove stains. These substances can damage the rubber coating. Improper care and cleaning can cause leaks to develop in the convertible top and its seams.< In the event of more serious soiling, use a special convertible top cleaner. When doing so, follow the manufacturer's directions for use. After three to five washings, treat the convertible top with sealant. Hand washing When washing the vehicle by hand, use plenty of water and car washing shampoo. Clean the vehicle with gentle pressure using a sponge or a washing brush. Before cleaning the windshield, deactivate the rain sensor or switch off the ignition to prevent unwanted wiper operation.< Follow local guidelines for washing vehicles by hand.< Headlamps Do not rub dry and never use abrasives or strong solvents to clean the covers. Loosen dirt, e.g. insects, with shampoo or insect remover and wash away with plenty of water. Use a window de-icer to remove accumulated ice and snow, not a scraper. Windows Use a glass cleaner to clean the inside and outside surfaces of the windows and the glass surfaces of the mirrors. Do not use quartz-containing cleansers to clean glass surfaces of the mirrors.< Caring for the vehicle finish Regular care helps your vehicle retain its value and protects the paint from the long-term effects of aggressive substances. Regionally occurring environmental factors can affect and damage vehicle finish. It is therefore important to tailor the frequency and extent of your car care accordingly. Immediately remove particularly aggressive substances such as spilled fuel, oil, grease, brake fluid, tree resin, or bird droppings; otherwise, they may damage your paint. Wiper blades Clean with soapy water and replace regularly to prevent streaking. The presence of wax and sealant residues and dirt on the windows leads to streaking during wiper operation and results in premature wear on wiper blades as well as interference with the rain sensor.< 228 Online Edition for Part no. 01 41 2 600 759 - © 08/08 BMW AG
