• When multiple vehicles are approaching with only a small gap between each vehi-
cle
• When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your vehicle and the
vehicle that enters the detection area
• When the difference in speed between your vehicle and another vehicle is
changing
• When a vehicle enters a detection area traveling at about the same speed as your
vehicle
• As your vehicle starts from a stop, a vehi- cle remains in the detection area
• When driving up and down consecutive
steep inclines, such as hills, dips in the

right or left at the rear of the vehicle and alerts the driver of the presence of such
vehicles by flashing the outside rear view mirror indicators and sounding a buzzer.

WARNING
■Cautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always drive safely, taking care
to observe your surroundings.
The BSM function is a supplementary
function which alerts the driver that a
vehicle is in a blind spot of the outside
rear view mirrors or is approaching rap-
idly from behind into a blind spot. Do not
overly rely on the BSM function. 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 correctly
under certain condit ions, the driver’s
own visual confirmation of safety is nec-
essary.
