▼ Blind Spot Monitoring (BSM)

The BSM is designed to assist the driver
in checking the area to the rear of the
vehicle on both sides during lane
changes by notifying the driver of the
presence of vehicles approaching from
the rear in an adjacent lane.
BSM operation
The BSM detects vehicles approaching
from the rear while traveling in the
forward direction at a speed of 10
km/h (6.3 mph) or faster and notifies
the driver by turning on the BSM
warning indicator light and displaying
the vehicle detection screen.
If the turn signal lever is operated to
signal a turn in the direction in which
the BSM warning indicator light is
illuminated while the approaching
vehicle is detected, the BSM notifies
the driver of possible danger flashing
on the BSM warning indicator light,
and by activating the warning sound
and the warning screen indicator
display.
