that are traveling in an adjacent lane in the area that is not reflected in
the outside rear view mirror (the blind spot), and advises the driver of
the vehicle’s existence via the outside rear view mirror indica tor.
The areas that vehicles can be detected in are outlined below.

WARNING
■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 over ly 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 resultin g 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.
