03 07.09 BODY RAIN CLEARING MIRRORS The rear view mirrors have been coated to produce a "rain clearing" effect. This coating causes the raindrops to spread, clearing the driver's rear view when it rains. It is sufficient to wash the mirrors with water for day to day care. The rain clearing effect is reduced in drizzle and light rain. In the following cases, the rain clearing effect will be reduced temporarily, but will gradually recover. D After wiping dirt off the mirrors D When the mirrors fog up D After waxing your vehicle in an automatic car wash D After your vehicle has been parked for a long period in underground parking lots, etc. where there is no direct sunlight. If you would like to restore the rain clearing effect to its normal level immediately in the above cases, wash the mirrors with neutral detergent, then rinse thoroughly. NOTICE To maintain the rain clearing ability, and prevent the mirrors from being scratched, observe the following precautions. D Do not use any glass cleaners that contain compounds. D If ice should jam the mirror, do not scrape the mirror. Use a spray deicer to free the mirror. D Wash off any wax stuck to the mirrors with neutral detergent and rinse thoroughly as any wax on the surface of the mirrors can cause the rain clearing effect to be lost. D Do not use any water repellents as they can destroy the rain clearing effect. If any repellent gets stuck on the surface of the mirrors, wash it off with neutral detergent, then rinse thoroughly. 400
