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 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.
● 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 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.

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 direction of your
vehicle
● People may not be detected if they are wearing certain types of clothing.
● Moving objects such as people or animals
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 Toyota 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.

Driving
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 ma y occur due to the vehicle sud-
denly moving forward due to an accidental accelerator pedal
operation, the vehicle moving th e unintended direction due to
the wrong shift position being se lected, or while parking or trav-
eling at low speeds, the sensors detect objects, such as a wall ,
in the traveling direction of t he vehicle, and the system opera tes
to lessen an impact with an object and reduce the resulting dam -
age.
Examples of system operation

3044-5. Using the driving support systems
◆When the accelerator ped al is depressed excessively
◆When the vehicle moves in the unintended direction due to the
wrong shift position being selected

3054-5. Using the driving support systems

Driving
If a radar sensor detects a vehicle approaching from the right or left at
the rear of the vehicle and a collision may occur, this functio n will per-
form brake control to reduce th e likelihood of an impact with the
approaching vehicle.
■Examples of system operation
The system will operate in situat ions such as the following if an
object is detected in the traveling direction of the vehicle.
◆When reversing, a vehicle is approaching and the brake pedal
is not depressed, or is depressed late

system will not be re-enabled by turning the engine switch off and then to
IGNITION ON mode.

Driving
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 w ill operate to
either limit acceleration or restrict output as much as possibl e.

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

3104-5. Using the driving support systems
■The Intelligent Clearance Sonar function will operate when
The function will operate when the ICS OFF indicator is not illuminated or
flashing ( P. 306, 314) 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 a nd 6 to 13 ft. (2
to 4 m) away.
• The system determines that a stronger-than-normal brake operat ion is
necessary to avoid a collision.
● Brake control
• Engine output restriction control is operating.
• The system determines that an emergency brake operation is nec essary
to avoid a collision.
■ The Intelligent Clearance Sonar function will stop operating when
The function will stop operating if any of the following condit ions 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
• The Intelligent Clearance Sonar system is disabled.
• Approximately 2 seconds elapse after the vehicle is stopped by brake
control.
• The brake pedal is depressed after the vehicle is stopped by b rake 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 Intellig ent Clearance Sonar function
The detection range of the Intelligent Clearance Sonar function differs from
the detection range of the intuitive parking assist. ( P. 298)
Therefore, even if the intuitive parking assist detects an obje ct and provides a
warning, the Intelligent Clearance Sonar function may not start operating.
■ If the Intelligent Clearance Sonar function has operated
If the vehicle is stopped due to operation of the Intelligent C learance Sonar
function, the Intelligent Clearance Sonar system will be disabl ed and the ICS
OFF indicator will illuminate.
