*Some models.
Blind Spot Monitoring (BSM) *
The Blind Spot Monitoring (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.
The Blind Spot Monitoring (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 noti¿ es
the driver by turning on the Blind Spot Monitoring (BSM) warning indicator light and
displaying the vehicle detection screen (vehicles with multi-information display and active
driving display).
If the turn signal lever is operated to signal a turn in the direction in which the Blind Spot
Monitoring (BSM) warning indicator light is illuminated while the approaching vehicle is
detected, the Blind Spot Monitoring (BSM) noti¿ es the driver of possible danger by turning
on the Blind Spot Monitoring (BSM) warning indicator light, and by activating the warning
sound and the warning screen indicator display (vehicles with multi-information display and
active driving display).
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.

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
Blind Spot Monitoring (BSM) warning indicator light, the warning sound and the warning
screen indicator display may not activate or they 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.

(rear). Remove any snow, ice or mud on the rear bumper.
 


y Driving on snow-covered roads for long periods.



y The temperature near the radar sensors (rear) becomes extremely hot due to driving
for long periods on slopes during the summer.
 


y The battery voltage has decreased. 



y Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be dif¿ cult to detect them.

y A vehicle is in the detection area at the rear in an adjacent driving lane but it does not
approach. The Blind Spot Monitoring (BSM) determines the condition based on radar
detection data.
 


y A vehicle is traveling alongside your vehicle at nearly the same speed for an extended
period of time.
 


y Vehicles approaching in the opposite direction.



y A vehicle in an adjacent driving lane is attempting to pass your vehicle.

y Directly after pressing the Blind Spot Monitoring (BSM) OFF switch and the system
becomes operable.
 


y If the road width is extremely narrow, vehicles two lanes over may be detected.
The detection area of the radar sensors (rear) is set according to the road width of
expressways.
 


y The Blind Spot Monitoring (BSM) warning indicator light may turn on and the vehicle
detection screen may be displayed in the display in reaction to stationary objects
(guardrails, tunnels, sidewalls, and parked vehicles) on the road or the roadside.

may be activated several times when making a turn at a city intersection.
 y Turn off the Blind Spot Monitoring (BSM) while pulling a trailer or while an accessory
such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radar’s
radio waves will be blocked causing the system to not operate normally.

 y The radar sensors (rear) of the Blind Spot Monitoring (BSM) may be regulated under
the radio wave related laws of the country where the vehicle is driven. The sensors
in this system are approved for use in the U.S.A. (including territories), Canada, and
Mexico. If a vehicle with a Blind Spot Monitoring (BSM) is driven in a country other
than the U.S.A., Canada, or Mexico, the system has to be turned off using the Blind Spot
Monitoring (BSM) OFF switch.
 


y The system switches to the Rear Cross Traf¿ c Alert function when the selector lever is
shifted to the reverse (R) position.
