Care Preservation A preservation treatment is necessary when water no longer beads off the clean paintwork surface. Only use products for paintwork preservation that contain carnauba or synthetic waxes. Clean the upholstery down to the seams using a sweeping motion. Avoid strong rubbing.< Opened Velcro fasteners, etc., on pants or other articles of clothing can damage the seat covers. Ensure that Velcro fasteners are closed.< Rubber seals Treat only with water or rubber care products. Do not use silicon-containing care products on rubber seals; otherwise, noise and damage could occur.< Leather/leather trim The leather used by BMW is a high quality natural product. Slight irregularities in the leather are a typical characteristic of natural leather.< Dust and road grit in the pores and folds of the leather have an abrasive effect, leading to increased wear and causing the leather surface to become brittle prematurely. Therefore, regularly dust the leather with a cloth, for example. Clean light-colored leather more frequently as dust and dirt are more noticeable. Treat the leather at least once every two months using a leather lotion as dirt and grease will gradually attack the leather's protective layer. Rivets, etc., on pants or other articles of clothing can damage the seat covers.< Chrome parts Carefully clean vehicle parts, such as the radiator grill, door handles or window frames, with copious quantities of water and a shampoo additive. For additional treatment, use a chrome polish. Light-alloy wheels For technical reasons, dust is generated during braking that is deposited on the light-alloy wheels. Remove the dust regularly using acidfree rim cleaner. Do not use aggressive, acidic, strongly alkaline and abrasive cleaning agents or steam jets over 1407/606; otherwise, damage may occur.< Carpets / cargo area You can vacuum the carpets and floor mats or clean them with interior cleaner if heavily soiled. The floor mats can be removed for cleaning. When replacing the mats, ensure that the seat rails do not extend over the floor mats, as this may damage the mats. Lint on the floor mats occurs for technical reasons and can be removed by vacuuming repeatedly. When cleaning the interior, do not move both seats all the way forward while moving them to their uppermost position and leaning the backrests forward. Otherwise, the seats could hit and damage the seal on the windshield, the sun visor or the headliner.< Outside sensors / cameras Keep the sensors and cameras on the outside of the vehicle, e.g., those of Park Distance Control, clean and free of ice to ensure that they remain fully functional.< Interior care Upholstery fabrics/cloth trims/ Alcantara fabrics Vacuum regularly with a vacuum cleaner to remove superficial dirt. To remove severe spots such as stains from beverages, use a soft sponge or lint-free microfiber cloth and suitable interior cleaners. Follow the instructions on the packaging. 210 Online Edition for Part no. 01 41 2 602 883 - © 08/09 BMW AG
