Operation Vehicle care To prevent damage to the antenna, unscrew and remove antenna on left rear side of vehicle before taking the vehicle through a car wash. Note that without the antenna on the left rear side of the vehicle installed, the signaling range of the SmartKey is considerably reduced. Hold the SmartKey in close proximity towards the antenna base when locking and unlocking the vehicle. In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the undercarriage, do not forget to clean the inner sides of the wheels. Ornamental moldings For regular cleaning and care of very dirty chrome-plated parts, use a chrome cleaner. Headlamps, side makers, tail lamps, 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 use only a soft, non-scratchy cloth when cleaning the lenses. Do not attempt to wipe dirty lenses with a dry cloth or sponge. Wiper blades ! The windshield wipers must be in a vertical position before folding them away from the windshield. They could otherwise damage the hood. Switch on wipers and place them in a vertical position. For information on placing the wipers in a vertical position, see "Replacing wiper blades" ( page 386). 337
