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 alerting the driver to the pr esence of vehicles approaching
from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while travel ing in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and turns o n the BSM warning lights
equipped on the door mirrors depending on the conditions. If th e turn signal lever is
operated to signal a lane change in the direction in which the BSM warning light is
illuminated, the system warns the driver of a vehicle in the detection area by flashing the
BSM warning light and activating a beep sound.
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the doors to about 50 m (164 ft) behind t he vehicle.
Detection areas Your vehicle
WARNING
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a
lane change. Due to certain limitations with the operation of this system, the BSM warning
light may not flash or it might be delayed even though a vehicle is in an adjacent driving lane.
Always make it your responsibility as a driver to check the rear.
