Automatic car wash NOTICE To prevent damage to the antenna, make sure it is retracted before driving your vehicle through an automatic car wash. Your vehicle may be washed in an automatic car wash, but remember that the paint can be scratched by some type of brushes, unfiltered washing water, or the washing process itself. Scratching reduces paint durability and gloss, especially on darker colors. The manager of the car wash should be able to advise you whether the process is safe for the paint on your vehicle. NOTICE Do not use gasoline or strong solvents, which may be toxic or cause damage. 3. Rinse thoroughly - dried soap can cause streaking. In hot weather you may need to rinse each section right after you wash it. 4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not rub or press hard - you might scratch the paint.
