Blind Spot Monitoring (BSM) System

*

The Blind Spot Monitoring (BSM) system 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 

presence of vehicles approaching from the rear in an adjacent lane.

The Blind Spot Monitoring (BSM) system 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 turns on the 

Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors depending on 

the conditions. If the turn signal lever is operated to signal a lane change in the direction 

in which the Blind Spot Monitoring (BSM) warning light is illuminated, the system warns 

the driver of a vehicle in the detection area by flashing the Blind Spot Monitoring (BSM) 

warning light and activating a beep sound.

The detection area on this system covers the driving lanes on both sides of the vehicle and 

from the rear part of the doors to about 50 m (164 ft) behind the 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 

Blind Spot Monitoring (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.
