Automatic day/night model
System which automatically and progressively changes between the day and night uses.

In order to prevent dazzle, the interior mirror glass darkens automatically in relation to the intensity of the light from the rear.
It lightens when the light (light beam of following vehicles, sun...) decreases, so guaranteeing optimum visibility.
In order to guarantee optimum visibility during your manoeuvres, the mirror lightens automatically when reverse gear is engaged.
