Cautions regarding the use of 

the system

There is a limit to the degree of 

recognition accuracy and control 

performance that this system can 

provide, do not overly rely on this 

system. The driver is always 

responsible for paying attention to 

the vehicle’ surroundings and 

driving safely.

■

To ensure the system can 

operate properly

Observe the following precau-

tions.
Failing to do so may result in the 

vehicle being unable to be driven 

safely and possibly cause an acci-

dent.

●

Do not damage the sensors, 

and always keep them clean.

If “Parking Assist Unavailable 

Clean Parking Assist Sensor” is 

displayed on the multi-informa-

tion display

A sensor may be covered with water 

drops, ice, snow, dirt, etc. Remove 

the water drops, ice, snow, dirt, etc., 

from the sensor to return the system 

to normal.
Also, due to ice forming on a sensor 

at low temperatures, a warning 

message may be displayed or the 

sensor may not be able to detect an 

object. Once the ice melts, the sys-

tem will return to normal.
If a warning message is displayed 

even if the sensor is clean, there 

may be a sensor malfunction. Have 

the vehicle inspected by your Toyota 

dealer.

WARNING

●

Do not attach a sticker or install 

an electronic component, such 

as a backlit license plate (espe-

cially fluorescent type), fog 

lights, fender pole or wireless 

antenna near a radar sensor.

●

Do not subject the surrounding 

area of the sensor to a strong 

impact. If subjected to an 

impact, have the vehicle 

inspected by your Toyota 

dealer. If the front or rear 

bumper needs to be 

removed/installed or replaced, 

contact your Toyota dealer.

●

Do not modify, disassemble or 

paint the sensors.

●

Do not attach a license plate 

cover.

●

Keep your tires properly 

inflated.

■

When to disable the function

In the following situations, disable 

the function as it may operate 

even though there is no possibility 

of a collision.

●

Failing to observe the warnings 

above.

●

A non-genuine Toyota suspen-

sion (lowered suspension, etc.) 

is installed.

■

Notes when washing the vehi-

cle

Do not apply intensive bursts of 

water or steam to the sensor 

area.
Doing so may result in the sensor 

malfunctioning.

●

When using a high pressure 

washer to wash the vehicle, do 

not spray the sensors directly, 

as doing so may cause a sensor 

to malfunction.

●

When using steam to clean the 

vehicle, do not direct steam too 

close to the sensors as doing so 

may cause a sensor to malfunc-

tion.

■

Sensor detection information

●

The sensor’s detection areas are 

limited to the areas around the 

vehicle’ front and rear bumpers.

●

The following situations may occur 

during use.

• Depending on the shape of the 

object and other factors, the 

detection distance may shorten, or 

detection may be impossible.

• Detection may be impossible if 

static objects draw too close to the 

sensor.

• There will be a short delay 

between static object detection 

and display (warning buzzer 

sounds). Even at low speeds, 

there is a possibility that the object 

will come within 11.9 in. (30 cm) 

before the display is shown and 

the warning buzzer sounds.

• It might be difficult to hear the 

buzzer due to the volume of the 

audio system or air flow noise of 

the air conditioning system.

• It may be difficult to hear the 

sound of this system due to the 

buzzers of other systems.

■

Objects which the system may 

not be properly detected

The shape of the object may pre-

vent the sensor from detecting it. 

Pay particular attention to the follow-

ing 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 direc-

tion of your vehicle

■

Situations in which the system 

may not operate properly

Certain vehicle conditions and the 

surrounding environment may affect 

the ability of a sensor to correctly 

detect objects. Particular instances 

where this may occur are listed 

below.

●

There is dirt, snow, water drops or 

ice on a sensor. (Cleaning the 

sensors will resolve this problem.)

●

A sensor is frozen. (Thawing the 

area will resolve this problem.) 

In especially cold weather, if a 

sensor is frozen the sensor dis-

play may be displayed abnormally, 

or objects, such as a wall, may not 

be detected.

●

When a sensor or the area around 

a sensor is extremely hot or cold.

●

On an extremely bumpy road, on 

an incline, on gravel, or on grass.

●

When vehicle horns, vehicle 

detectors, motorcycle engines, air 

brakes of large vehicles, the clear-

ance sonar of other vehicles or 

other devices which produce ultra-

sonic waves are near the vehicle

●

A sensor is coated with a sheet of 

spray or heavy rain.

●

If objects draw too close to the 

sensor.

●

When a pedestrian is wearing 

clothing that does not reflect ultra-

sonic waves (ex. skirts with gath-

ers or frills).

●

When objects that are not perpen-

dicular to the ground, not perpen-

dicular to the vehicle traveling 

direction, uneven, or waving are in 

the detection range.

●

Strong wind is blowing

●

When driving in inclement weather

motorcycle, bicycle or pedestrian 

cuts in front of the vehicle or runs 

out from the side of the vehicle

●

If the orientation of a sensor has 

been changed due to a collision or 

other impact

●

When equipment that may 

obstruct a sensor is installed, such 

as a towing eyelet, bumper pro-

tector (an additional trim strip, 

etc.), bicycle carrier, or snow plow

Situations in which the system 

may operate even if there is no 

possibility of a collision

Instances of the RCTA function 

unnecessary detecting a vehicle 

and/or object may increase in the 

following situations:

●

When the parking space faces a 

street and vehicles are being 

driven on the street

●

When the distance between your 

vehicle and metal objects, such as 

a guardrail, wall, sigh, or parked 

vehicle, which may reflect electri-

cal waves toward the rear of the 

vehicle, is short

●

When equipment that may 

obstruct a sensor is installed, such 

as a towing eyelet, bumper pro-

tector (an additional trim strip, 

etc.), bicycle carrier, or snow plow

●

When a vehicle passes by the 

side of your vehicle

●

When a detected vehicle turns 

while approaching the vehicle

●

When there are spinning objects 

near your vehicle such as the fan 

of an air conditioning unit

●

When water is splashed or 

sprayed toward the rear bumper, 

such as from a sprinkler

●

Moving objects (flags, exhaust 

fumes, large rain droplets or 

snowflakes, rain water on the road 

surface, etc.)

●

When the distance between your 

vehicle and a guardrail, wall, etc., 

that enters the detection area is 

short

The Parking Support Brake 
system consists of the fol-
lowing functions that oper-
ate when driving at a low 
speed or backing up, such 
as when parking. When the 
system determines that the 
probability of a collision 
with a detected object or 
pedestrian is high, a warn-
ing operates to urge the 
driver to take evasive 
action. If the system deter-
mines that the possibility of 
a collision with a detected 
object or pedestrian is 
extremely high, the brakes 
are automatically applied to 
help avoid the collision or 
help reduce the impact of 
the collision.

WARNING

■

Cautions regarding the use of 

the system

Do not overly rely on the system, 

as doing so may lead to an acci-

dent.
Always drive while checking the 

safety of the surroundings of the 

vehicle.
Depending on the vehicle and 

road conditions, weather, etc., the 

system may not operate.
The detection capabilities of sen-

sors and radars are limited. 

Always drive while checking the 

safety of the surroundings of the 

vehicle.

●

The driver is solely responsible 

for safe driving. Always drive 

carefully, taking care to observe 

your surroundings. The Parking 

Support Brake system is 

designed to provide support to 

lessen the severity of collisions. 

However, it may not operate in 

some situations.

●

The Parking Support Brake sys-

tem is not designed to stop the 

vehicle completely. Additionally, 

even if the system has stopped 

the vehicle, it is necessary to 

depress the brake pedal imme-

diately as brake control will be 

canceled after approximately 2 

seconds.

●

It is extremely dangerous to 

check the system operations by 

intentionally driving the vehicle 

into the direction of a wall, etc. 

Never attempt such actions.

■

When to disable the Parking 

Support Brake

In the following situations, disable 

the Parking Support Brake as the 

system may operate even though 

there is no possibility of a colli-

sion.

●

When inspecting the vehicle 

using a chassis roller, chassis 

dynamo or free roller

●

When loading the vehicle onto a 

boat, truck or other transport 

vessel

●

If the suspension has been 

modified or tires of a size other 

than specified are installed

●

If the front of the vehicle is 

raised or lowered due to the 

carried load

●

When equipment that may 

obstruct a sensor is installed, 

such as a towing eyelet, bumper 

protector (an additional trim 

strip, etc.), bicycle carrier, or 

snow plow

●

When using automatic car 

washing devices

●

If the vehicle cannot be driven in 

a stable manner, such as when 

the vehicle has been in an acci-

dent or is malfunctioning

●

When the vehicle is driven in a 

sporty manner or off-road

●

When the tires are not properly 

inflated

●

When the tires are very worn

●

When a tire chains, compact 

spare tire or an emergency tire 

puncture repair kit is used
