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 ashing 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 front 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 fl ash 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.
NOTE
The Blind Spot Monitoring (BSM) system will operate when all of the following
conditions are met:
The ignition is switched ON.
The Blind Spot Monitoring (BSM) switch is pressed and the Blind Spot Monitoring
(BSM) OFF indicator light in the instrument cluster is turned off.
The vehicle speed is about 10 km/h (6.3 mph) or faster.
