BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on the
inner side of the rear bumper
on the left and right side to
assist the driver in confirming
safety when changing lanes.
WA R N I N G
■Cautions regarding the use of the system
The driver is solely responsible for
safe driving. Always drive safely, tak- ing care to observe your
surroundings.
The Blind Spot Monitor is a supple- mentary function which alerts the
driver that a vehicle is in a blind spot
of the outside rear view mirrors or is approaching rapidly from behind into
a blind spot. Do not overly rely on the
Blind Spot Monitor. As the function cannot judge if it is safe to change
lanes, over reliance could lead to an
accident resulting in death or serious injury.
As the system may not function cor-
rectly under certain conditions, the driver’s own visual confirmation of
safety is necessary.
