■The RCTA function is operational when
The RCTA function operates when all of the following conditions are met:
● The BSM system is set to on. (P. 336)
● The shift lever is in R.
● Vehicle speed is less than approximately 8 km/h (5 mph).
● Approaching vehicle speed is between approximately 8 km/h (5 mph) and
28 km/h (18 mph).
■ Conditions under which the RCTA function will not detect a vehicle
The RCTA function is not designed to detect the following 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

• Immediately after the RCTA function is set to on
• Immediately after the hybrid system is started with the RCTA function is
set to on
● Instances of the RCTA 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
• When the parking space faces a
street and vehicles are being driven
on the street

Toyota parking assist-sensor
: 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 multi-information display
and a buzzer. Always check the surrounding area when using
this system.

This system can be enabled/disabled on the multi-information display.
Press “ ” or “” of the meter control switches, select .
Press “ ” or “” of the meter control switches, select .
Press on the meter con-
trol switches to enable/dis-
able the system.
When enabled, the Toyota
parking assist-sensor indica-
tor will illuminate.
Once turned off, the Toyota parking assist-sensor will remain OFF until it is
turned ON again via the screen of the multi-information display. (The
system will not automatically turn ON even when the hybrid system is
restarted.)
When the sensors detect an obstacle, a graphic is shown on the multi
information display depending on the position and distance to the
obstacle.

■The Toyota parking assist-sensor can be operated when
The power switch is in ON mode.
● Front corner sensors/front center sensors:
• The shift lever is in a position other than P.
• Vehicle speed is approximately 10 km/h (6 mph) or less
● Front side sensors/rear side sensors:
• The shift lever is in a position other than P.
• Vehicle speed is approximately 10 km/h (6 mph) or less
• Steering wheel is turned approximately 90° or more
● Rear corner sensors/rear center sensors:
The shift lever is in R.
■ Sensor detection information
● The sensor detection areas are limited to the areas around the vehicle bum-
pers.
● Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.
● Obstacles may not be detected if they are too close to the sensor.
● There will be a short delay between obstacle detection and display. Even
when traveling at a low speed, if you come too close to an obstacle before
the display and buzzer activate, the display and buzzer may not activate at
all.
● 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.

■ Side area obstacle warning function
Obstacle notified (within the vehicle course)
● Only when obstacles on the sides are in the vehicle course will the driver be
notified (display and buzzer).
● Although the display operates while the vehicle is stopped or moving, the
buzzer only sounds during movement.
■ Obstacle detection in side areas
● Obstacles may not be detected in the side areas until the scan completes.
After the power switch is turned to ON mode, scanning completes after driv-
ing the vehicle for a short period of ti me. The operation display is grayed out
until the scans are completed.
● When an obstacle such as another vehicle, pedestrian or animal is detected
by the side sensors, the obstacle may continue to be detected even after it
has left the side sensor detection area.
■ If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In this case, clean the
sensor and the system should return to normal.
If a sensor is frozen due to low temperatures, a warning message may be dis-
played or an obstacle may not be detected. When the sensor thaws out, the
system should return to normal.
■ If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
The system may not operate due to the malfunction of a sensor. Have the
vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: P. 679)
When an obstacle in the side areas is
within the vehicle course while the vehicle
is moving forward or backward, this func-
tion inform the driver by the display and
the buzzer.

cle course)

WARNING
■When using Toyota parking assist-sensor
Observe the following precautions to avoid an unexpected accident.
● Do not exceed the speed limit of 10 km/h (6 mph).
● The sensor 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 the 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 the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen, the screen may show an
abnormal display, or obstacles may not be detected.
● The sensor is covered in any way.
● In harsh sunlight or intense cold weather
● On an extremely bumpy road, on an incline, on gravel, or on grass
● The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles , or other loud noises producing ultra-
sonic waves.
● The sensor is splashed with water or drenched with heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is leaning considerably to one side.
● The vehicle is equipped with a fender pole or wireless antenna.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● The area directly under the bumpers is not detected.
● If obstacles draw too close to the sensor.
● The bumper or sensor receives a strong impact.
● A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
● There is another vehicle equipped with parking assist sensors in the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate, license plate holder, etc., are installed.
In addition to the examples above, depending on the shape and condition of
obstacles, detection may not be possible, or the detection range may be
shortened.
