The BSM function uses radar sensors to detect the following vehicles
traveling in adjacent lanes and advises the driver of the presence of
such vehicles via the indicators on the outside rear view mirrors.
Vehicles that are traveling in areas that are not visible using the out-
side rear view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that are
not visible using the outside rear view mirrors (the blind spots)

The areas that vehicles can be detected in are outlined below.
The range of each detection area is:
Approximately 0.5 m (1.6 ft.) to 3.5 m (11.5 ft.) from either side of
the vehicle*
*: The area between the side of the vehicle and 0.5 m (1.6 ft.) from the side
of the vehicle cannot be detected.
Approximately 1 m (3.3 ft.) forward of the rear bumper
Approximately 3 m (9.8 ft.) from the rear bumper
Approximately 3 m (9.8 ft.) to 60 m (197 ft.) from the rear bumper*
*: The greater the difference in speed between your vehicle and the detected
vehicle is, the farther away the vehicle will be detected, causing the out-
side rear view mirror indicator to illuminate or flash.

■The BSM function is operational when
The BSM function is operational when all of the following conditions are met:
● The BSM system is set to on (P. 132)
● The shift lever is in a position other than R.
● Vehicle speed is greater than approximately 16 km/h (10 mph)
■ The BSM function will detect a vehicle when
The BSM function will detect a vehicle pr esent in the detection area in the fol-
lowing situations:
● A vehicle in an adjacent lane overtakes your vehicle.
● Another vehicle enters the detection area when it changes lanes.
■ Conditions under which the BSM function will not detect a vehicle
The BSM function is not designed to detect the following types of vehicles
and/or objects:
● Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles traveling in the opposite direction
● Guardrails, walls, signs, parked vehicles and similar stationary objects*
●Following vehicles that are in the same lane*
●Vehicles traveling 2 lanes away from your vehicle*
*: Depending on conditions, detection of a vehicle and/or object may occur.
WARNING
■ Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the
driver that a vehicle is present in the blind spot. Do not overly rely on the
Blind Spot Monitor function. The functi on cannot judge if it is safe to change
lanes, therefore over reliance could cause an accident resulting in death or
serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

■ Conditions under which the BSM function may not function correctly
● The BSM function may not detect vehicles correctly in the following situa-
tions:
• When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area
• When mud, snow, ice, a sticker, etc., is covering the sensor or surround-
ing area on the rear bumper
• When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching with only a small gap between
each vehicle
• When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your vehicle and
the vehicle that enters the detection area
• When the difference in speed between your vehicle and another vehicle
is changing
• When a vehicle enters a detection area traveling at about the same
speed as your vehicle
• As your vehicle starts from a stop, a vehicle remains in the detection area
• When driving up and down consecutive steep inclines, such as hills, dips
in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven
surfaces
• When vehicle lanes are wide, or when driving on the edge of a lane, and
the vehicle in an adjacent lane is far away from your vehicle
• When a bicycle carrier or other accessor y is installed to the rear of the
vehicle
• When there is a significant difference in height between your vehicle and
the vehicle that enters the detection area
• Immediately after the BSM system is set to on

● Instances of the BSM function unnecessarily detecting a vehicle and/or
object may increase in the following situations:
• When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area
• When the distance between your vehicle and a guardrail, wall, etc., that
enters the detection area is short
• When driving up and down consecutive steep inclines, such as hills, dips
in the road, etc.
• When vehicle lanes are narrow, or when driving on the edge of a lane,
and a vehicle traveling in a lane other than the adjacent lanes enters the
detection area
• When driving on roads with sharp bends, consecutive curves, or uneven
surfaces
• When the tires are slipping or spinning
• When the distance between your vehicle and a following vehicle is short
• When a bicycle carrier or other accessor y is installed to the rear of the
vehicle

The RCTA functions when your vehicle is in reverse. It can detect
other vehicles approaching from the right or left rear of the vehicle. It
uses radar sensors to alert the driver of the other vehicle’s existence
through flashing the outside rear view mirror indicators and sounding
a buzzer.

WARNING
■ Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The RCTA function is only a supplement ary function which alerts the driver
that a vehicle is approaching from the right or left at the rear of the vehicle.
As the RCTA function may not functi on correctly under certain conditions,
the driver’s own visual confirmation of safety is necessary. Over reliance on
this function may lead to an accident resulting death or serious injury.

The areas that vehicles can be detected in are outlined below.
To give the driver a more consistent time to react, the buzzer can alert
for faster vehicles from farther away.

■The RCTA function is operational when
The RCTA function operates when all of the following conditions are met:
● The BSM system is set to on. (P. 336)
● The shift lever is in R.
● Vehicle speed is less than approximately 8 km/h (5 mph).
● Approaching vehicle speed is between approximately 8 km/h (5 mph) and
28 km/h (18 mph).
■ Conditions under which the RCTA function will not detect a vehicle
The RCTA function is not designed to detect the following types of vehicles
and/or objects:
● Vehicles approaching from directly behind
● Vehicles backing up in a parking space next to your vehicle
● Guardrails, walls, signs, parked vehicles and similar stationary objects*
●Small motorcycles, bicycles, pedestrians, etc.*
