■Conditions under which the Blind Spot Monitor function may not func-
tion correctly
●The Blind Spot Monitor function may not detect vehicles correctly in the fol-
lowing situations:
• 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 Blind Spot Monitor main switch is turned on
● Instances of the Blind Spot Monitor function unnecessarily detecting a vehi-
cle 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 vehicle. It uses radar sensors to alert the driver of the other vehi-
cle’s existence through fl ashing the outside rear view mirror indicators
and sounding a buzzer.

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 Rear Cross Traffic Alert function is only an assist and is not a replace-
ment for careful driving. The driver must be careful when backing up, even
when using the Rear Cross Traffic Alert function. The driver’s own visual
confirmation of behind you and your vehicle is necessary and be sure there
are no pedestrians, other vehicles etc. before backing up. Failure to do so
could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

Driving
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.
Example:
■ The Rear Cross Traffic Alert function is operational when
● The BSM system is set to on. ( P. 139)
● The shift position is in R.
● Vehicle speed is less than approximately 5 mph (8 km/h).
● Approaching vehicle speed is between approximately 5 mph (8 km/h) and
18 mph (28 km/h).
