Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the
driver that a vehicle is present in the blind spot. Do not overly rely on the Blind
Spot Monitor function. The function cannot judge if it is safe to change lanes,
therefore over reliance could cause an accident resulting in death or serious
injury.
According to conditions, the system may not function correctly. Therefore the
driver’s own visual confirmation of safety is necessary.
