CAUTION Since the mirror surfaces can get hot, do not touch them when the mirror heater switch is on. Make sure you turn the mirror heaters off when the surfaces are clear. Leaving the mirror heaters on for a long time could cause the battery to discharge, especially during stop−and−go driving. The mirror heaters are not designed for drying rain water or for melting snow. If the outside rear view mirrors are heavily coated with ice, use a spray de−icer before operating the switch. NOTICE To prevent the battery from being discharged, turn the switch off when the engine is not running. 116
