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 engine 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 engine switch is in IGNITION 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 engine switch is in IGNITION 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 engine switch is in IGNITION 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 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.

2824-5. 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
48004f000f0003005200550003005200510003004a00550044[ss.
●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.

If the engine output restriction control or brake control operates, a
buzzer will sound and a message will be displayed on the multi-infor-
mation display to alert the driver.
Depending on the situation, engine output restriction control will operate to
either limit acceleration or restrict output as much as possible.

If the Intelligent Clearance Sonar function detects that a collision with
an object is possible, the engine output will be restricted to restrain
any increase in the vehicle speed. (Engine output restriction control:
See A below.)
Additionally, if the accelerator pedal continues to be depressed, the
brakes will be applied automatically to reduce the vehicle speed.
(Brake control: See B below.)

■The Intelligent Clearance Sonar function will operate when
The function will operate when the ICS OFF indicator is not illuminated or
flashing (P. 287, 295) and all of the following conditions are met:
●Engine output restriction control
• The Intelligent Clearance Sonar system is enabled.
• The vehicle speed is 10 mph (15 km/h) or less.
• There is an object in the traveling direction of the vehicle and 6 to 13 ft. (2
to 4 m) away.
• The system determines that a stronger-than-normal brake operation is
necessary to avoid a collision.
●Brake control
• Engine output restriction control is operating.
• The system determines that an emergency brake operation is necessary
to avoid a collision.
■The Intelligent Clearance Sonar function will stop operating when
The function will stop operating if any of the following conditions are met:
●Engine output restriction control
• The Intelligent Clearance Sonar system is disabled.
• The collision becomes avoidable with normal brake operation.
• The object is no longer 6 to 13 ft. (2 to 4 m) away in the traveling direction
of the vehicle.
●Brake control

• Approximately 2 seconds elapse after the vehicle is stopped by brake
control.
• The brake pedal is depressed after the vehicle is stopped by brake con-
trol.
• The object is no longer 6 to 13 ft. (2 to 4 m) away in the traveling direction
of the vehicle.
■Detection range of the Intelligent Clearance Sonar function
The detection range of the Intelligent Clearance Sonar function differs from
the detection range of the intuitive parking assist. (P. 279)
