Fu nction of the 360° Camera
The 360° Camera is a sy stem that consists of
fo ur cameras. The cameras co verth e immediate

Night View Assist is only an aid. The driver is
re sponsible forth e dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane.
% As inf rare d light is not visible tothe human

when there is oncoming traf fic.
The infrared headlamps switch on in the
dark from speeds of appr oximately 5 mph
(10 km/h). This means that, while station‐

cannot check whe ther Night View Assist is
wo rking.
Sy stem limitations
Night View Assist cannot displ ayobjects directly
in front of or directly next totheve hicle. It may
be the case that objects are highlighted as well
as pedestrians or animals.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
