REAR VIEW MIRROR
Adjustable mirror providing a central rearward view.
Equipped with an anti-dazzle system, which darkens the mirror glass
and reduces the nuisance to the driver caused by the sun, headlamps
from other vehicles...
Automatic day/night model
By means of a sensor, which measures the light from the rear of the
vehicle, this system automatically and progressively changes between
the day and night uses.
In order to ensure optimum visibility during your manoeuvres,
the mirror lightens automatically when reverse gear is engaged.
Due to the curve of the rear screen, the image in the rear view
mirror may be slightly distorted; take this into account when
manoeuvring the vehicle.
