The rear view mirrors have been coated to produce a ªrain
clearingº 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.
