WARNING
■Handling the radar sensor
● Keep the sensor and its surrounding area on the bumper clean at all times.
● Do not subject a sensor or its surrounding area on the rear bumper to a
strong impact.
If a sensor is moved even slightly off position, the system may malfunction
and vehicles may not be detected correctly.
In the following situations, have your vehicle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is scratched or dented, or part of
them has become disconnected.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
● Do not modify the sensor or surrounding area on the bumper.
● Do not paint the rear bumper any color other than an official Toyota color.
One Blind Spot Monitor sensor is
installed inside the left and right side of
the vehicle rear bumper respectively.
Observe the following to ensure the Blind
Spot Monitor can function correctly.

The Blind Spot Monitor function uses radar sensors to detect vehicles
that are traveling in an adjacent lane in the area that is not reflected in
the outside rear view mirror (the blind spot), and advises the driver of
the vehicle’s existence via the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 3.5 m (11.5 ft.)
from the side of the vehicle
The first 0.5 m (1.6 ft.) from the
side of the vehicle is not in the
detection area
Approximately 3 m (9.8 ft.) from
the rear bumper
Approximately 1 m (3.3 ft.) for-
ward of the rear bumper

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 accessory 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 accessory is installed to the rear of the
vehicle

The Rear Crossing Traffic Alert 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 indi-
cators 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 Crossing Traffic Alert function is only an assist and is not a
replacement for careful driving. The driver must be careful when backing
up, even when using the Rear Crossing 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.

■ Conditions under which the Rear Crossing Traffic Alert function will not
detect a vehicle
The Rear Crossing Traffic Alert function is not designed to detect the follow-
ing 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.*
●Vehicles moving away from your vehicle
● Vehicles approaching from the parking spaces next to your vehicle*
*: Depending on the conditions, detection of a vehicle and/or object may
occur.
● Vehicles that the sensors cannot detect
due to obstructions

● Instances of the Rear Crossing Traffic Alert function unnecessarily detecting
a vehicle and/or object may increase in the following situations:
• When a vehicle passes by the side of your vehicle
• When the distance between your vehicle and metal objects, such as a
guardrail, wall, sign, or parked vehicle, which may reflect electrical waves
toward the rear of the vehicle, is short
• When the sensors cannot detect a
vehicle due to obstructions

The Toyota parking assist-sensor
can be enabled/disabled on the
screen ( P. 250) of the
multi-information display.
When on is selected, Toyota park-
ing assist-sensor indicator will
come on.
Once off is selected, the Toyota parking assist-sensor will not return to on
until it is turned to on by the screen of multi-information display again.
(The system does not automatically return to on even when the hybrid sys-
tem is restarted.)
: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via the displays and a buzzer.
Always check the surrounding area when using this system.
