WARNING

■

Cautions regarding the use of

the system

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

conditions, the driver’s own visual

confirmation of safety is neces-

sary.
Over reliance on this function may

lead to an accident resulting

death or serious injury.

■

Outside rear view mirror indica-

tor visibility

In strong sunlight, the outside rear

view mirror indicator may be difficult

to see.

■

Hearing the RCTA buzzer

The RCTA buzzer may be difficult to

hear over loud noises, such as if the

audio system volume is high.

■

When “Rear Cross Traffic Alert

Unavailable” is shown on the

multi-information display

Ice, snow, mud, etc., may be

attached to the rear bumper around

the sensors. (

P.276) Removing

the ice, snow, mud, etc., from the

the sensors to normal. Additionally,

the function may not function nor-

mally when used in extremely hot or

cold environments.

■

When “Rear Cross Traffic Alert

is shown on the multi-informa-

tion display

There may be a sensor malfunction

or misaligned. Have the vehicle

inspected at a Toyota dealer.

■

Operation of the RCTA
function

The RCTA function uses rear
side radar sensors to detect
vehicles approaching from the

right or left at the rear of the
vehicle and alerts the driver of
the presence of such vehicles
by flashing the outside rear view
mirror indicators and sounding a
buzzer.

PKSB (Parking Sup-

port Brake)

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.

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. 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.

●

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 tire chains, a compact

spare tire or an emergency tire

puncture repair kit are used.

●

When your vehicle is towing a

trailer or during emergency tow-

ing.

4-5. Using the driving support systems

The Parking Support Brake can
be enabled/disabled on the

screen of the multi-information
display. All of the Parking Sup-
port Brake functions (static
objects and rear-crossing vehi-
cles) are enabled/disabled
simultaneously. (



P.98, 107)

When the Parking Support Brake is
disabled, the PKSB OFF indicator
(



P.80) illuminates on the multi-

information display.

To re-enable the system, select

on the multi-information display,
select

and turn it on.

If the system is disabled, it will
remain off even if the engine switch
is turned to ON after the engine
switch has been turned off.

If the engine output restriction
control or brake control oper-
ates, a buzzer will sound and a
message will be displayed on
the multi-information display or
Multimedia Display, to alert the
driver.

Depending on the situation, engine
output restriction control will oper-
ate to either limit acceleration or
restrict output as much as possible.

the vehicle carefully, paying atten-

tion to your surroundings. It may

be necessary to drive the vehicle

for a certain amount of time

before the system returns to nor-

mal. (If the system does not return

to normal after driving for a while,

clean the sensors and their sur-

rounding area on the bumpers.)

If the Parking Support Brake

has operated

If the vehicle is stopped due to oper-

ation of the Parking Support Brake,

the Parking Support Brake will be

disabled and the PKSB OFF indica-

tor will illuminate. If the Parking Sup-

port Brake operates unnecessarily,

brake control can be canceled by

depressing the brake pedal or wait-

ing for approximately 2 seconds for

it to automatically be canceled.

Then, the vehicle can be operated

by depressing the accelerator pedal.

■

Re-enabling the Parking Sup-

port Brake

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.296), or turn the engine

switch to 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 “PKSB Unavailable” is dis-

played on the multi-information

display and the PKSB OFF indi-

cator is flashing

If this message is displayed, a sen-

sor on the front or rear bumper may

be dirty. Clean the sensors and their

surrounding area on the bumpers.

■

If “PKSB Unavailable” and

“Parking Assist Unavailable

are displayed on the multi-infor-

mation display and the PKSB

●

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

normal.

●

Water may be continuously flow-

ing over the sensor surface, such

as in a heavy rain. When the sys-

tem determines that it is normal,

the system will return to normal.

■

If a battery terminal has been

disconnected and reconnected

The system needs to be initialized.

To initialize the system, drive the

vehicle straight ahead for 5 seconds

or more at a speed of approximately

22 mph (35 km/h) or more.

Parking Support Brake function (static objects)

If the sensors detect a static object, such as a wall, in the
traveling direction of the vehicle and the system determines
that a collision may occur due to the vehicle suddenly 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 traveling at
low speeds, the system will operate to lessen the impact with
the detected static object and reduce the resulting damage.
