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 À 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.

Warning Beep
The Blind Spot Monitoring (BSM) or Rear Cross Traf¿ c Alert (RCTA) system noti¿ es the
driver of the presence of vehicles in adjacent lanes to the rear of your vehicle using the
Blind Spot Monitoring (BSM) warning lights and the warning beep while the systems are
operational.
Blind Spot Monitoring (BSM) warning lights
The Blind Spot Monitoring (BSM) warning lights are equipped on the left and right door
mirrors. The warning lights turn on when a vehicle approaching from the rear in an adjacent
lane is detected.


When the ignition is switched ON, the malfunction warning light turns on momentarily and
then turns off after a few seconds.
Forward driving (Blind Spot Monitoring (BSM) system operation)
The Blind Spot Monitoring (BSM) system detects vehicles approaching from the rear and
turns on the Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors
according to the conditions. Additionally, while a Blind Spot Monitoring (BSM) warning
light is illuminated, if the turn signal lever is operated to signal a turn in the direction
in which the Blind Spot Monitoring (BSM) warning light is illuminated, the Blind Spot
Monitoring (BSM) warning light À ashes.
Reverse driving (Rear Cross Traf¿ c Alert (RCTA) system operation)
The Rear Cross Traf¿ c Alert (RCTA) system detects vehicles approaching from the left and
right of your vehicle and À ashes the Blind Spot Monitoring (BSM) warning lights.

Rear Cross Traf¿ c Alert (RCTA)
T h e R e a r C r o s s T r a f¿ c Alert (RCTA) system is designed to assist the driver in checking the
area to the rear of the vehicle on both sides while the vehicle is reversing by alerting the
driver to the presence of vehicles approaching the rear of the vehicle.
The Rear Cross Traf¿ c Alert (RCTA) system detects vehicles approaching from the left and
right sides of the vehicle while the vehicle is being reversed out of a parking space, and
noti¿ es the driver of possible danger using the Blind Spot Monitoring (BSM) warning lights
and the warning buzzer.

Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible
collision using an indicator and warning sound in the instrument cluster while the vehicle
is being driven at about 15 km/h or faster (10 mph or faster) and the system's radar sensor
determines that your vehicle may hit a vehicle or obstruction ahead.

WARNING
Do not rely completely on the Forward Obstruction Warning (FOW) system and always
drive carefully:
Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of
a collision. The ability to detect an obstruction is limited depending on the obstruction,
weather conditions, or traffi c conditions. Therefore, if the accelerator pedal or brake
pedal is mistakenly operated it could result in an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safe
distance from vehicles ahead or on-coming vehicles.

N O T E
 


y The Forward Obstruction Warning (FOW) system operates when all of the following
conditions are met:
 


y The ignition is switched ON.



y The Forward Obstruction Warning (FOW) system is on.



y The vehicle speed is about 15 km/h (10 mph) or faster.



y The relative speed between your vehicle and the vehicle or obstruction ahead is about
15 km/h (10 mph) or faster.
 


y The Forward Obstruction Warning (FOW) system may not operate under the following
conditions:
 


y If there is the possibility of hitting only a part of a vehicle or obstruction ahead.



y If the vehicle is accelerated rapidly and it comes close to a vehicle ahead.



y The DSC is malfunctioning.



y The vehicle is driven at the same speed as the vehicle ahead.



y The accelerator pedal is depressed.



y The brake pedal is depressed.



y The steering wheel is being operated.



y The selector lever is being operated.



y The turn signal is being used.

y Although the objects which activate the system are 4-wheeled vehicles, the radar sensor
could detect the following objects, determine them to be an obstruction, and operate the
Forward Obstruction Warning (FOW) system.
 


y Objects on the road at the entrance to a curve (including guardrails and snow banks).



y A vehicle appears in the opposite lane while cornering or rounding a curve.



y When crossing a narrow bridge.



y When passing under a low gate or through a tunnel or narrow gate.



y When entering an underground parking area.



y Metal objects, bumps, or protruding objects on the road.



y If you suddenly come close to a vehicle ahead.



y When driving in areas where there is high grass or forage.



y Two-wheeled vehicles such as motorbikes or bicycles.



y Pedestrians or non-metallic objects such as standing trees. 



y When the system operates, the user is noti¿ ed by the À ashing Forward Obstruction
Warning (FOW) indicator light (red) and the active driving display.
 


y The Forward Obstruction Warning (FOW) warning light (amber) turns on when the
system has a malfunction.
