The RCTA functions when your vehicle is in reverse. It can detect
other vehicles approaching from the right or left rear of the v ehicle. It
uses radar sensors to alert the driver of the other vehicle’s existence
through flashing the outside rear view mirror indicators and so unding
a buzzer.
■RCTA icon displa y (if equipped)
When a vehicle approaching from the right or left at the rear o f the
vehicle is detected, the following will be displayed on the aud io sys-
tem screen.

■Conditions under which the RCTA function may not function corre ctly
● The RCTA function may not detect vehicles correctly in the following condi-
tions:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When ice or mud, etc. is attached to the rear bumper
• During bad weather such as heavy rain, fog, snow, etc.
• When multiple vehicles approach continuously
• Shallow angle parking
• When a vehicle is approaching at high speed
• When parking on a steep incline, such as hills, a dip on the road, etc.
• Directly after the RCTA function is turned on
• Directly after the hybrid system is started with the RCTA func tion on.
• When items such as a bicycle carrier are installed on the rear of the vehi-
cle
● Instances of the RCTA function unnecessarily detecting a vehicl e 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
The brightness of the indicators on the outside rear view mirro rs and
the volume of the RCTA buzzer can be changed on (4.2-inch dis-
play) or (7-inch display) ( P. 113, 129) of the multi-information
display.
• Vehicles that the sensors cannot detect because of obstacles
• When the parking space faces a street and vehicles are being driven
on the street

The distance from your vehicle to nearby objects when parallel
parking or maneuvering into a garage is measured by the sen-
sors and communicated via the displays and a buzzer. Always
check the surrounding area wh en using this system.

■Buzzer operation and distance to an object
A buzzer sounds when the sensors are operating.
● The buzzer sounds faster as the vehicle approaches an object.
When the vehicle comes within the following distance of the
object, the buzzer sounds continuo usly: Approximately 1.2 ft. (35
cm).
● When 2 or more objects are detec ted simultaneously, the buzzer
system responds to the nearest object. If one or both come with in
the above distances, the beep will repeat a long tone, followed by
fast beeps.

Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely close to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.

■Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’s
bumper.
● Depending on the shape of the object and other factors, the det ection dis-
tance may shorten, or detection may be impossible.
● Objects may not be detected if they are too close to the sensor .
● There will be a short delay between object detection and displa y. Even at
slow speeds, there is a possibility that the object will come w ithin the sen-
sor’s detection areas before the display is shown and the buzze r sounds.
● Thin posts or objects lower than the sensor may not be detected 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 the air conditioning system.
■ If “Parking Assist Unavailable Please Clean Parking Assist Sens or” is
displayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In such case s, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a mal function dis-
play may appear or an object may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Unavailable” is displayed on the multi-infor mation dis-
play
Water may be continuously flowing over the sensor surface, such as in a
heavy rain. When the system determines that it is normal, the system will
return to normal.
■ Certification
For vehicles sold in Canada
This ISM device complies with Canadian ICES-001.
Cet appareil ISM est conforme a la norme NMB-001 du Canada.
WARNING
■ When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be d riven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle ( especially
the sides of the vehicle) for safety, and drive slowly, using t he brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.

WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an object. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen the screen ma y show an
abnormal display, or objects may not be detected.
● The sensor is covered in any way.
● The vehicle is leaning considerably to one side.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● The vicinity of the vehicle is noisy due to vehicle horns, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● There is another vehicle equipped with parking assist sensors i n the vicin-
ity.
● The sensor is coated with a sheet of spray or heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is equipped with a fender pole or wireless antenna.
● Towing eyelets are installed.
● The bumper or sensor receives a strong impact.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● In harsh sunlight or intense cold weather.
● The area directly under the bumpers is not detected.
● If objects draw too close to the sensor.
● A non-genuine Toyota suspension (lowered suspension, etc.) is i nstalled.
● A backlit license plate is installed.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

3164-5. Using the driving support systems
WARNING
■Objects which may not be properly detected
The shape of the object may prevent a sensor from detecting it. Pay partic-
ular attention to the following objects:
● Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low objects
● Tall objects with upper sections projecting outwards in the dir ection of your
vehicle
● People may not be detected if they are wearing certain types of clothing.
NOTICE
■When using intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyot a dealer.
● The intuitive parking assist operation display flashes, and a buzzer sounds
when no objects are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows continuously without beeping, except when the buzzer
volume is muted.
● If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■ Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor a rea.
Doing so may result in the sensor malfunctioning.
