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.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for
safe driving. Always drive safely,
taking care to o bserve your sur-
roundings.
The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a v ehicle 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 seri-
ous injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.
