CAUTION

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.
