If the image is distorted, have the basic settings
checked by a dealer's service center or another

The windshield is part of the system.
The shape of the windshield makes it possible to
display a precise image.
A film in the windshield prevents double images
from being generated.
For this reason, it is strongly suggested to have
the special windshield replaced by a dealer's
service center or another qualified service center
or repair shop, if necessary.
