occur.
■Conditions under which the RCTA function may not function correctly
●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 sensor or its
surrounding area
• When mud, snow, ice, a sticker, etc., is covering the sensor or surround-
ing area on 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 in the road, etc.
• Immediately after the RCTA function is turned on
• Immediately after the hybrid system is started with the RCTA function on.
• When items such as a bicycle carrier are installed on the rear of the vehi-

■The intuitive parking assist can be operated when
●Front corner sensors:
• The power switch is in ON mode.
• The shift lever is in other than P.
• The vehicle speed is less than about 6 mph (10 km/h).
●Front center sensors:
• The power switch is in ON mode.
• The shift lever is in other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Rear corner and rear center sensors:
• The power switch is in ON mode.
• The shift lever is in R.
• The vehicle speed is less than about 6 mph (10 km/h).
■Intuitive parking assist display
When an object is detected while the Toyota parking assist monitor or pan-
oramic view monitor 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 the vehicle’s
bumper.
●Depending on the shape of the object and other factors, the detection 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 display. Even at
slow speeds, there is a possibility that the object will come within the sen-

●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 a battery terminal has been disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the vehicle straight ahead for 5 seconds or more
at a speed of approximately 22 mph (35 km/h) or more.
■If “Parking Assist Unavailable Please Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction 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-information 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.
●Initialization may not have been performed after a battery terminal was dis-
connected and reconnected. Initialize the system. If this message continues
to be displayed even after initialization, have the vehicle inspected by your
Toyota dealer.
■Customization
Some functions can be customized. (P. 111, 527)
WARNING
■When using the intuitive parking assist
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 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 the brake to
control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.

2984-5. Using the driving support systems
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 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 objects may not be detected.
●The sensor is covered in any way.
●The vehicle is leaning considerably to one side.
●<0032005100030044005100030048005b00570055004800500048004f005c00030045005800500053005c00030055005200440047000f0003005200510003004400510003004c00510046004f004c00510048000f0003005200510003004a00550044005900

●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.
●There is another vehicle equipped with parking assist sensors in 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 installed.
●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.

3004-5. Using the driving support systems
The system will operate in situations such as the following if an object
is detected in the traveling direction of the vehicle.
◆When traveling at a low speed and the brake pedal is not
depressed, or is depressed late
Intelligent Clearance Sonar (ICS)
: If equipped
If a collision with an object may occur due to the vehicle sud-
denly moving forward due to an accidental accelerator pedal
operation, the vehicle moving the unintended direction due to
the wrong shift position being selected, or while parking or trav-
eling at low speeds, the sensors detect objects, such as a wall,
in the traveling direction of the vehicle, and the system operates
to lessen an impact with an object and reduce the resulting dam-
age.
Examples of system operation

3084-5. Using the driving support systems
■Re-enabling the Intelligent Clearance Sonar system
To re-enable the Intelligent Clearance Sonar system when it is disabled due
to operation of the Intelligent Clearance Sonar function, either enable the sys-
tem again (P. 303), or turn the power switch off and then back to ON mode.
Additionally, if the object becomes no longer in the traveling direction of the
vehicle or if the traveling direction of the vehicle changes (such as changing
from moving forward to backing up, or from backing up to moving forward),
the system will be re-enabled automatically.
■Objects that the Intelligent Clearance Sonar function may not detect
The sensors may not be able to detect certain objects, such as the following.
●Cotton cloth, snow, and other materials that are poor reflectors of ultrasonic
waves.
(People may also not be detected depending on the type of clothing they are
wearing.)
●Objects which are not perpendicular to the ground, are not perpendicular to

●Low objects
●Thin objects such as wires, fences, ropes and signposts
●Objects that are extremely close to the bumper
■Situations in which the Intelligent Clearance Sonar may not operate
properly
When the shift lever is in N.
■Intuitive parking assist buzzer
Regardless of whether the intuitive parking assist system is enabled or not
(P. 292), if the Intelligent Clearance Sonar system is enabled (P. 303),
the front or rear sensors detect an object and brake control is performed, the
intuitive parking assist buzzer will sound to notify the driver of the approxi-
mate distance to the object.
