Buzzer

When an obstacle is detected, the buzzer sounds.

● As the obstacle is approached, the buzzer sounds more rapidly.

When the obstacle is extremely close, the buzzer switches from

sounding intermittently (short beeps) to continuously (a long beep).

• Distance to obstacle detected by front corner sensor is approxi-

mately 1.2 ft. (35 cm) or less

• Distance to obstacle detected by front side sensor or rear side

sensor is approximately 1.0 ft. (30 cm) or less

• Distance to obstacle detected by front sensor is approximately

1.2 ft. (35 cm) or less

• Distance to obstacle detected by rear corner sensor is approxi-

mately 1.2 ft. (35 cm) or less

• Distance to obstacle detected by back sensor is approximately

1.2 ft. (35 cm) or less

● When an obstacle is detected by multiple sensors simultaneously,

the buzzer sounds according to the distance to the closest obsta-

cle.

● When obstacles are simultaneously detected to the front and rear

of the vehicle, separate buzzers sound patterns according to the

distance to each obstacle.

The volume and timing of the buzzer can be changed. (P. 678)

■Sensor detection information

●The sensor’s detection areas are limited to the areas around the vehicle’s

bumper.

●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.

■Obstacle warning function

When an obstacle in the side areas is within the vehicle course while the

vehicle is moving forward or backward, this function inform the driver by the

display and the buzzer.

Calculated vehicle course

■Obstacle detection in side areas

●Obstacles in the side areas are detected while driving by scanning the side

areas with the side sensors. Recognized obstacles are retained in memory

for up to approximately 2 minutes.

●Obstacles may not be detected in the side areas until the scan completes.

After the power switch is turned on, scanning completes after driving the

vehicle for a short period of time.

●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 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 obstacle may not be detected. If the sensor thaws out,

the system should return to normal.

■If “Parking Assist Malfunction” is displayed on the multi-information dis-

play

Depending on the malfunction of the sensor, the device may not be working

normally. Have the vehicle inspected by your Toyota dealer.

■Certification (Canada only)

This ISM device complies with Canadian ICES-001.

■Customization

Settings (e.g. buzzer volume) can be changed.

(Customizable features: P. 678)

WARNING

■When using intuitive parking assist

Observe the following precautions to avoid an unexpected accident.

●Do not exceed the speed limit 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 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 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 is 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.

WARNING

■Side sensors

In the following situations, the intuitive parking assist may not operate nor-

mally and may result in an unexpected accident. Drive carefully.

●Obstacles may not be detected in the side areas until the vehicle is driven

for a short time and a scan of the side areas is completed. (P. 356)

●Even after the scan of the side areas is completed, obstacles such as

other vehicles, people or animals that approach from the sides cannot be

detected.

●Even after the scan of the side areas is completed, obstacles may not be

detected depending on the surrounding situation of the vehicle.

At that time, the side sensor operation displays (P. 351) temporary turn

off.

■Obstacles which may not be properly detected

The shape of the obstacle may prevent the sensor from detecting it. Pay

particular attention to the following obstacles:

4

●Wires, fences, ropes, etc.

●Cotton, snow and other materials that absorb sound waves

●Sharply-angled objects

●Low obstacles

●Tall obstacles 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.

●Intuitive parking assist operation display flashes, and a beep sounds when

no obstacles 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 up and remains on without a beep.

●If a display error occurs, first check the sensor.

If the error occurs even when 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.

●When using steam to wash the vehicle, do not direct steam too close to

the sensors. The sensors may not function properly if subjected to steam.
