installed behind the rear
bumper. This function is
intended to assist the driver
in checking areas that are
not easily visible when
backing up.

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’s surroundings and

driving safely. (

WARNING

■

Cautions regarding the use of

the 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.

■

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

4-5. Using the driving support systems

ing

The buzzer can alert the driver
of faster vehicles approaching
from farther away.
Example:

■

The RCTA function is opera-

tional when

The RCTA function operates when

all of the following conditions are

met:

●

The power switch is in ON.

●

The RCTA function is on.

●

The shift lever is in R.

●

The vehicle speed is approxi-

mately 5 mph (8 km/h) or less.

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 col-
lision.

Brake) system

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.

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

●

When using automatic car

washing devices

●

If the vehicle cannot be driven in

a stable manner, such as when

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.

a collision may occur due to the vehicle suddenly moving for-
ward due to an accidental accelerator pedal operation, the
vehicle moving the unintended direction due to the wrong
