■Intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h).
● Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R.
■ Intuitive parking assist display
When an obstacle is detected while the Toyota parking assist mo nitor is in
use, the warning indicator will appear in the upper part of the screen even if
the display setting has been set to off.
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’s
front corner and rear bumpers.
● The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sen sor.
• There will be a short delay between obstacle detection and dis play. Even
at slow speeds, there is a possibility that the obstacle will c ome within the
sensor’s detection areas before the display is shown and the wa rning
beep sounds.
• Thin posts or objects lower than the sensor may not be detected for colli- sion when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of air conditioning system.
■ Objects which the system may not be properly detected
●Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low obstacles
● Tall obstacles with upper sections projecting outwards in the d irection of
your vehicle

Situations in which the syst em may not operate properly
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is frozen. (Thawing t he area will resolve this problem .)
In especially cold weather, if a sensor is frozen the sensor di splay may be
displayed abnormally, or objects, such as a wall, may not be detected.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● 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
● A sensor is coated with a sheet of spray or heavy rain.
● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ult rasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandst orm
● When an object that cannot be detected is between the vehicle a nd a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
● If the orientation of a sensor has been changed due to a collis ion or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the car ried load
● If the vehicle cannot be driven in a stable manner, such as whe n the vehicle
has been in an accident or is malfunctioning
● When a tire chains, compact spare tire or an emergency tire pun cture repair
kit is used
●
When a sensor or the area around a
sensor is extremely hot or cold.

Outside rear view mirror indica-
tors
When a vehicle approaching from
the right or left at the rear of the
vehicle is detected, both outside
rear view mirror indicators will
flash.
Navigation system screen
If a vehicle approaching from the
right or left at the rear of the vehicle
is detected, the RCTA icon ( P.
288) for the detected side will be
displayed.
RCTA buzzer
If a vehicle approaching from the right or left at the rear of the vehicle is
detected, a buzzer will sound.
The RCTA function can be enabl ed/disabled on screen of the
multi-information display. ( P. 9 5 )
When the RCTA function is disabled, the “RCTA OFF” indicator wi ll come
on. Each time the engine switch is turned off then changed to t he IGNI-
TION ON mode, the RCTA function will be enabled automatically.
RCTA (Rear Cross Traffic Alert)
The RCTA function uses the BSM radar sensors installed on the
inner side of the rear bumper. This function is intended to ass ist
the driver in checking areas that are not easily visible when
backing up.

■Outside rear view mirror indicator visibility
In strong sunlight, the outside rear view mirror indicator may be difficult to
see.
■ Hearing the RCTA buzzer
The RCTA buzzer may be difficult to hear over loud noises, such as if the
audio system volume is high.
■ When “RCTA Unavailable” is shown on the multi-information displ ay
Water, snow, mud, etc., may be attached to the rear bumper around the sen-
sors ( P. 272). Removing the water, snow, mud, etc., from the vicinity of the
sensor area should return it to normal. Also, the sensor may no t function nor-
mally when used in extremely hot or cold weather.
■ When “RCTA Malfunction Visit Your Dealer” is shown on the multi -infor-
mation display
There may be a sensor malfunction or misaligned. Have the vehicle
inspected by your Toyota dealer.

Operation of the RCTA function
The RCTA function uses radar
sensors to detect vehicles
approaching from the right or left at the rear of the vehicle a nd
alerts the driver of the presence of such vehicles by flashing the
outside rear view mirror indi cators and sounding a buzzer.
Approaching vehicles
