When applying Mercedes-Benz approved Tire Care and Mercedes-Benz approved Wheel Care products, take care not to spray them on the brake disks. Plastic and rubber parts Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. ! Only use acid-free cleaning materials. Acid may cause corrosion or damage the clear coat. ! Do not use a dry cloth, abrasives, solvents or cleaners containing solvents. Do not touch the protective layer with hard objects such as an ice scraper or ring. Never apply strong force and only use a soft, non-scratching cloth when cleaning the rear part of the tilt/sliding panel*. Otherwise you may scratch or damage the protective layer. ! Do not use oil or wax on these parts. Instrument cluster and cup holders Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution. Wipe with a cloth moistened in a lukewarm solution. ! 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. Therefore, the vehicle's brake system should always be warmed-up before it is parked after cleaning. To do so, please drive your vehicle for several minutes to allow the brakes to dry. ! To prevent scratches, do not use scouring agents. 401
