Pre-collision braking

The system may not operate in the following situations:

If a 12-volt battery terminal has been disconnected and reconnected and

then the vehicle has not been driven for a certain amount of time

If the shift lever is in R

When the VSC OFF indicator is illuminated (only the pre-collision warning

function will be operational)

Object detection function

The system detects objects based

on their size, profile, motion, etc.

However, an object may not be

detected depending on the sur-

rounding brightness and the motion,

posture, and angle of the detected

object, preventing the system from

operating properly. (

P.272)

The illustration shows an image of

detectable objects.

Cancelation of the pre-collision

braking

If either of the following occur while

the pre-collision braking function is

operating, it will be canceled:

The accelerator pedal is

depressed strongly.

The steering wheel is turned

sharply or abruptly.

LTA (Lane Tracing

Assist)

While driving on a road with
clear white (yellow) lane
lines, the LTA system warns
the driver if the vehicle may
deviate from the current
lane or course

*

, and also

can slightly operate the
steering wheel to help avoid
deviation from the lane or
course

*

. Also, while the

dynamic radar cruise con-
trol with full-speed range is
operating, this system will
operate the steering wheel
to maintain the vehicle’s
lane position.
The LTA system recognizes
white (yellow) lane lines or a
course

*

using the front cam-

era. Additionally, it detects
preceding vehicles using
the front camera and radar.

*

: Boundary between asphalt and

the side of the road, such as
grass, soil, or a curb

WARNING

Before using LTA system

Do not rely solely upon the LTA

system. The LTA system does

not automatically drive the vehi-

cle or reduce the amount of

attention that must be paid to

the area in front of the vehicle.

The driver must always assume

full responsibility for driving

safely by paying careful atten-

tion to the surrounding condi-

tions and operating the steering

wheel to correct the path of the

vehicle. Also, the driver must

take adequate breaks when

fatigued, such as from driving

for a long period of time.

Failure to perform appropriate

driving operations and pay care-

ful attention may lead to an

accident, resulting in death or

serious injury.

When not using the LTA sys-

tem, use the LTA switch to turn

the system off.

Situations unsuitable for LTA

system

In the following situations, use the

LTA switch to turn the system off.

Failure to do so may lead to an

accident, resulting in death or

serious injury.

Vehicle is driven on a road sur-

face which is slippery due to

rainy weather, fallen snow,

freezing, etc.

Vehicle is driven on a snow-cov-

ered road.

White (yellow) lines are difficult

to see due to rain, snow, fog,

dust, etc.

Vehicle is driven in a temporary

lane or restricted lane due to

construction work.

In the following situations, a warning

message urging the driver to hold

the steering wheel and the symbol

shown in the illustration are dis-

played on the multi-information dis-

play to warn the driver. The warning

stops when the system determines

that the driver holds the steering

wheel. Always keep your hands on

the steering wheel when using this

system, regardless of warnings.

When the system determines the

driver is not holding the steering

wheel while the lane centering

function is operating.

If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned
and the function is temporarily can-
celed. This warning also operates in
the same way when the driver con-
tinuously operates the steering
wheel only a small amount.
The buzzer also sounds even if the
alert type is set to “Steering wheel

determines that the vehicle is driv-
ing around a curve, warnings will
occur earlier than during straight-
lane driving.

When the system determines that

the driver is driving without hold-

ing the steering wheel while the

WARNING

Cautions regarding the driv-

ing assist systems

Observe the following precau-

tions, as there are limitations to

the assistance provided by the

system. Failure to do so may

cause an accident resulting in

death or serious injury.

Assisting the driver to measure

following distance

The dynamic radar cruise control
with full-speed range is only
intended to help the driver in
determining the following distance
between the driver’s own vehicle
and a designated vehicle traveling
ahead. It is not a mechanism that
allows careless or inattentive driv-
ing, and it is not a system that can
assist the driver in low-visibility
conditions.
It is still necessary for driver to
pay close attention to the vehi-
cle’s surroundings.

Assisting the driver to judge

proper following distance

The dynamic radar cruise control
with full-speed range determines
whether the following distance
between the driver’s own vehicle
and a designated vehicle traveling
ahead is within a set range. It is
not capable of making any other
type of judgement. Therefore, it is
absolutely necessary for the
driver to remain vigilant and to
determine whether or not there is
a possibility of danger in any
given situation.

Assisting the driver to operate

the vehicle

The dynamic radar cruise control
with full-speed range does not
include functions which will pre-
vent or avoid collisions with vehi-
cles ahead of your vehicle.
Therefore, if there is ever any
possibility of danger, the driver
must take immediate and direct
control of the vehicle and act
appropriately in order to ensure
the safety of all involved.

Situations unsuitable for

dynamic radar cruise control

with full-speed range

Do not use dynamic radar cruise

control with full-speed range in

any of the following situations.

Doing so may result in inappropri-

ate speed control and could

cause an accident resulting in

death or serious injury.

Roads where there are pedes-

trians, cyclists, etc.

In heavy traffic

On roads with sharp bends

On winding roads

On slippery roads, such as

those covered with rain, ice or

snow

On steep downhills, or where

there are sudden changes

between sharp up and down

gradients

Vehicle speed may exceed the

set speed when driving down a

steep hill.

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable fol-

cle distance can also be set by operating the vehicle-to-vehicle
distance switch.

When driving on downhill slopes, the vehicle-to-vehicle distance may

4-5. Using the driving support systems

Example of constant speed cruising
When there are no vehicles ahead

The vehicle travels at the speed set by the driver.

Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears

When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not performed, system
control continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehicle will accel-
erate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side from where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane is
to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).

Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed

The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

WARNING

Cautions regarding the use of

the RCTA function

The driver is solely responsible for

safe driving. Always drive safely,

taking care to observe your sur-

roundings.
The RCTA function is only a sup-

plementary function which alerts

the driver that a vehicle is

approaching from the right or left

at the rear of the vehicle. As the

RCTA function may not function

correctly under certain condi-

tions, the driver’s own visual con-

firmation of safety is necessary.
Over reliance on this function may

lead to an accident resulting

death or serious injury.

and reaction times are limited.

When moving forward or revers-

ing, check the areas surround-

ing 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 near

the bumpers as those areas are

where this may occur are listed

below.

There is dirt, snow or ice on a sen-

sor. (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 abnor-

mally, or objects, such as a wall,

may not be detected.

A sensor is covered in any way.

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.

The vicinity of the vehicle is noisy

due to vehicle horns, motorcycle

engines, air brakes of large vehi-

cles, or other loud noises produc-

ing ultrasonic waves.

There is another vehicle equipped

with parking assist sensors in the

vicinity.

A sensor is coated with a sheet of

spray or heavy rain.

If a sensor is hit by a large amount

of water, such as when driving on

a flooded road.

If the vehicle is significantly tilted.

The vehicle is approaching a tall

or curved curb.

If objects draw too close to the

sensor.

Objects which may not be prop-

erly detected

The shape of the object may pre-

vent the sensor from detecting it.

Pay particular attention to the fol-

lowing objects:

Wires, fences, ropes, etc.

Cotton, snow and other materials

that absorb sound waves

Sharply-angled objects

1.0 ft. (30 cm) of the object,
the buzzer sounds continu-
ously.

When 2 or more sensors
simultaneously detect a static
object, the buzzer sounds for
the nearest object. If one or
more objects come within
approximately 1.0 ft. (30 cm)
of the vehicle, the buzzer will
repeat a long tone, followed
by fast beeps.

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
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the
collision.

PKSB (Parking Support
Brake) system

WARNING

Limitations of the Parking

Support Brake 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. Addition-

ally, even if the system has

stopped the vehicle, it is neces-

sary to depress the brake pedal

immediately as brake control

will be canceled after approxi-

mately 2 seconds.

Do not attempt to test the oper-

ation of the Parking Support

Brake system yourself.

Depending on the situations,

the system may not operate

properly, possibly leading to an

accident.

To re-enable the Parking Support

Brake when it is disabled due to

operation of the Parking Support

Brake, either enable the system

again (

P.320), or turn the power

switch off and then back to ON.

Additionally, if the object becomes

no longer in the traveling direction of

the vehicle or if the traveling direc-

tion of the vehicle changes (such as

changing from moving forward to

backing up, or from backing up to

moving forward), the system will be

re-enabled automatically.

If “Parking Support Brake

Unavailable Remove the Dirt of

the multi-information display

and the PKSB OFF indicator

illuminates

A sensor may be covered with ice,

snow, dirt, etc. In this case,

remove the ice, snow, dirt, etc.,

from the sensor to return the sys-

tem to normal. If this message is

shown even after removing dirt

from the sensor, or shown when

the sensor was not dirty to begin

with, have the vehicle inspected at

your Toyota dealer.

A sensor may be frozen. Once the

ice melts, the system will return to

WARNING

Do not replace a sensor with a

part other than a genuine part.

Do not subject a sensor or its

surrounding area to a strong

impact.

Do not damage the sensors,

and always keep them clean.

If the area around a radar sen-

sor is subjected to an impact,

the system may not operate

properly due to a sensor mal-

function. Have the vehicle

inspected by your Toyota

dealer.

Handling the suspension

Do not modify the suspension, as

changes to the height or inclina-

tion of the vehicle may prevent

the sensors from detecting

objects correctly or cause the sys-

tem to not operate or operate

unnecessarily.

If the Parking Support Brake

function (static objects) oper-

ates unnecessarily, such as

at a railroad crossing

In the event that the Parking Sup-

port Brake function (static objects)

operates unnecessarily, such as

at a railroad crossing, brake con-

trol will be canceled after approxi-

mately 2 seconds, allowing you to

proceed forward and leave the

area, brake control can also be

canceled by depressing the brake

pedal. Depressing the accelera-

tor pedal after brake control is

canceled will allow you to proceed

forward and leave the area.

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.

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

cle at a traveling speed of more

than approximately 5 mph (8

km/h)

• The shift lever is in R.

• The Parking Support Brake deter-

mines that a stronger than normal

brake operation is necessary to

avoid a collision with an approach-

ing vehicle.

Brake control

• Hybrid system output restriction

control is operating

• The Parking Support Brake deter-

mines that an emergency brake

operation is necessary to avoid a

collision with an approaching vehi-

cle.

The Parking Support Brake

function (rear-crossing vehi-

cles) will stop operating when

The function will stop operating if

any of the following conditions are

met:

Hybrid system output restriction

control

• The Parking Support Brake is dis-

abled.

• The collision becomes avoidable

with normal brake operation.

• A vehicle is no longer approaching

from the right or left at the rear of

the vehicle.

Brake control

• The Parking Support Brake is dis-

abled.

• Approximately 2 seconds have

elapsed since the vehicle was

stopped by brake control.

• The brake pedal is depressed

after the vehicle is stopped by

brake control.

• A vehicle is no longer approaching

from the right or left at the rear of

the vehicle.

Detection area of the Parking

Support Brake function (rear-

crossing vehicles)

The detection area of the Parking

Support Brake function (rear-cross-

ing vehicles) differs from the detec-

tion area of the RCTA function

(

P.306). Therefore, even if the

RCTA function detects a vehicle

and provides an alert, the Parking

Support Brake function (rear-cross-

ing vehicles) may not start operat-

ing.

WARNING

Do not modify, disassemble or

paint the sensors.

Do not replace a rear radar sen-

sor with a part other than a gen-

uine part.

Do not damage the rear radar

sensors, and always keep the

radar sensors and their sur-

rounding area on the bumper

clean.

If the area around a rear radar

sensor is subjected to an

impact, the system may not

operate properly due to a sen-

sor malfunction. Have the vehi-

cle inspected by your Toyota

dealer.

Observe the rear radar sensor

handling precautions. (

P.301)

Conditions under which the

Parking Support Brake func-

tion (rear-crossing vehicles)

will not detect a vehicle

The Parking Support Brake function

(rear-crossing vehicles) is not

designed to detect the following

types of vehicles and/or objects:

Vehicles approaching from

directly behind

Vehicles backing up in a parking

space next to your vehicle

Vehicles that the sensors cannot

detect due to obstructions

Vehicles which suddenly acceler-

ate or decelerate near your vehi-

cle

Guardrails, walls, signs, parked

vehicles and similar stationary
objects

*

Small motorcycles, bicycles,
pedestrians, etc.

*

Vehicles moving away from your

vehicle

Vehicles approaching from the

parking spaces next to your vehi-
cle

*

Objects which are extremely close
to a radar sensor

*

Vehicles which are approaching

from the right or left at the rear of

the vehicle at a traveling speed of

less than approximately 5 mph (8

km/h)

Vehicles which are approaching

from the right or left at the rear of

the vehicle at a traveling speed of

more than approximately 15 mph

(24 km/h)

*

: Depending on the conditions,

detection of a vehicle and/or
object may occur.

RCTA buzzer

Regardless of whether the RCTA

function is enabled or not (

P.310),

if the Parking Support Brake func-

tion is enabled (

P.320) and brake

control is performed, a buzzer will

sound to notify the driver.

Situations in which the system

may operate even though there

is no possibility of a collision

In some situations such as the fol-

lowing, the Parking Support Brake

function (rear-crossing vehicles)

may operate even though there is

no possibility of a collision.

When the parking space faces a

street and vehicles are being

driven on the street

When a detected vehicle turns

while approaching the vehicle

When a vehicle passes by the

side of your vehicle

-------------------------------------------------------------------------------------------------------------------------------------------------------------

4-5. Using the driving support systems

When the distance between your

vehicle and metal objects, such as

a guardrail, wall, sign, or parked

vehicle, which may reflect electri-

cal waves toward the rear of the

vehicle, is short

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

Situations in which the Parking

Support Brake function (rear-

crossing vehicles) may not

operate properly

In some situations, such as the fol-

lowing, the radar sensors may not

detect an object and this function

may not operate properly

Stationary objects

When a sensor or the area around

a sensor is extremely hot or cold

If the rear bumper is covered with

ice, snow, dirt, etc.

When it is raining heavily or water

strikes the vehicle

When the detection area of a

radar sensor is obstructed by an

adjacent vehicle

If the vehicle is significantly tilted

When equipment that may

obstruct a sensor is installed, such

as a bumper protector (an addi-

tional trim strip, etc.), hitch-

mounted bicycle carrier, or snow

plow

If the suspension has been modi-

fied 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

If a sticker or an electronic compo-

nent, such as a backlit license

plate (especially fluorescent type),

fog lights, fender pole or wireless

antenna is installed near a radar

sensor

If the orientation of a radar sensor

has been changed

When multiple vehicles are

approaching with only a small gap

between each vehicle

If a vehicle is approaching the rear

of your vehicle rapidly

Situations in which the radar sen-

sor may not detect a vehicle

• When a vehicle approaches from

the right or left at the rear of the

vehicle while you are turning while

backing up

• When turning while backing up

• When backing out of a shallow

angle parking spot
