CAUTION Since the mirror surfaces can get hot, keep your hands off them when the mirror heaters 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. 90
