Do not touch the inside of the front, rear or side windows with hard objects such as an ice scraper or ring. Doing so may damage the windows. Light alloy wheels If possible, clean wheels once a week. X Use Mercedes-Benz approved Wheel Care, a soft bristle brush and a strong spray of water for cleaning the light alloy wheels. When applying Mercedes-Benz approved Tire Care and Mercedes-Benz approved Wheel Care products, take care not to spray them on the brake disks.

Only use acid-free cleaning materials. Acid may cause corrosion or damage the clear coat. ! The vehicle should not be parked for an extended period of time immediately after it has been cleaned, especially not after the wheel rims have been cleaned with wheel rim cleaner. Wheel rim cleaners can lead to increased corrosion of the brake disks and brake pads. Non-approved wheel cleaners may also damage the wheel paint if the vehicle is not driven after cleaning. Therefore, the vehicle's brake system should always be warmed-up before it is parked after cleaning. Drive your vehicle for several minutes to allow the brakes to dry. Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. X Wipe with a cloth moistened in a lukewarm solution. The surface may temporarily change color. If this is the case, wait for it to dry. G Warning! Do not use cleaners or cockpit care sprays containing solvents to clean the cockpit or the steering wheel. Cleaners containing solvents will make the surface porous and vehicle occupants could suffer serious injuries from plastic parts coming loose in the event of air bag deployment. ! Do not use oil, wax or scouring agents. Otherwise you may scratch or damage the surface. Use a standard microfiber cloth and apply with light pressure. Steering wheel X Wipe with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care. Carpets X Use Mercedes-Benz approved Carpet and Fabric Care for cleaning the carpets. 468
