■Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the following, the system may operate even
though there is no possibility of a collision.
●When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking lots)
●When there is a rut or hole in the surface of the road
●When driving on a metal cover (grating), such as those used for drainage
ditches
●When driving up or down a steep slope
●If a sensor is hit by a large amount of water, such as when driving on a
flooded road
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
●A sensor is coated with a sheet of spray or heavy rain
●When driving in inclement weather such as fog, snow or a sandstorm
●When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
●If the front of the vehicle is raised or lowered due to the carried load
●If the orientation of a sensor has been changed due to a collision or other
impact
●The vehicle is approaching a tall or curved curb
●Driving close to columns (H-shaped steel beams, etc.) in multi-story parking
garages, construction sites, etc.
●If the vehicle cannot be driven in a stable manner, such as when the vehicle
has been in an accident or is malfunctioning ●When driving on a narrow road
●When strong winds are blowing

●When a tire chains or compact spare tire is used ●On an extremely bumpy road, on an
incline, on gravel, or on grass
WARNING
■Cautions regarding the use of the system
There is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’ surroundings
and driving safely.
■To ensure the system can operate properly
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
●Do not damage the sensors, and always keep them clean.
●Do not attach a sticker or install an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire-
less antenna near a radar sensor.
●Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by your Toyota dealer.
If the front or rear bumper needs to be removed/installed or replaced, con-
tact your Toyota dealer.
●Do not modify, disassemble or paint the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.
■When to disable the function
In the following situations, disable the function as it may operate even
though there is no possibility of a collision.
●Failing to observe the warnings above.
●A non-genuine Toyota suspension (lowered suspension, etc.) is installed.

WARNING
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
●When using a high pressure washer to wash the vehicle, do not spray the
sensors directly, as doing so may cause a sensor to malfunction.
●When using steam to clean the vehicle, do not direct steam too close to

If a vehicle approaching from the right or left at the rear of the vehicle is
detected, the RCTA icon (P. 328) for the detected side will be displayed.
This illustration shows an example of a vehicle approaching from both
sides of the vehicle.
RCTA
buzzer
When a vehicle approaching from the right or left rear of the vehicle is
detected, a buzzer sounds from behind the rear seat.
RCTA (Rear Cross Traffic Alert)
: If equipped
The RCTA function uses the BSM rear side radar sensors
installed behind the rear bumper. This function is intended to
assist the driver in checking areas that are not easily visible
when backing up.

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.

When a vehicle approaching from the right or left at the rear of the
vehicle is detected, the following will be displayed on the audio sys-

●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
●Vehicles approaching from the parking spaces next to your vehicle
*
●The distance between the sensor and approaching vehicle gets too close
*: Depending on the conditions, detection of a vehicle and/or object may
occur.
■Situations in which the system may not operate properly
The RCTA function may not detect vehicles correctly in the following situa-
tions:

surrounding area
●When mud, snow, ice, a sticker, etc., is covering the sensor or surrounding
area on the position above 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 a vehicle is approaching at high speed
●When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or
snow plow ●Vehicles that the sensors cannot detect
due to obstructions

●When towing a trailer
●When there is a significant difference in height between your vehicle and the
vehicle that enters the detection area
●When a sensor or the area around a sensor is extremely hot or cold
●If the suspension has been modified or tires of a size other than specified
are installed
●If the front of the vehicle is raised or lowered due to the carried load ●When backing up on a slope with a
sharp change in grade

■Situations in which the system may operate even if there is no possibil-
ity of a collision
Instances of the RCTA function unnecessary detecting a vehicle and/or object
may increase in the following situations:
●When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or
snow plow
●When there are spinning objects near your vehicle such as the fan of an air
conditioning unit
●When water is splashed or sprayed a sprinkler
●Moving objects (flags, exhaust fumes, large rain droplets or snowflakes, rain
water on the road surface, etc.) ●When the parking space faces a street
and vehicles are being driven on the
street
●When the distance between your vehicle
and metal objects, such as a guardrail,
wall, sigh, or parked vehicle, which may
reflect electrical waves toward the rear
of the vehicle, is short
●When a vehicle passes by the side of
your vehicle
●When a detected vehicle turns while
approaching the vehicle

3344-5. Using the driving support systems
●When the distance between your vehicle and a guardrail, wall, etc., that
enters the detection area is short
