■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.
■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.
■Customization
Some functions can be customized. (P. 100, 506)
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.

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.

●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.

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.

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 area.
Doing so may result in the sensor malfunctioning.

2844-5. 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.

◆When the accelerator pedal is depressed excessively
◆When the vehicle moves in the unintended direction due to the
wrong shift position being selected

2864-5. Using the driving support systems
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 function will per-
form brake control to reduce the likelihood of an impact with the
approaching vehicle.
■Examples of system operation
The system will operate in situations 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

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.

Driving
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.)
