When driving on a road with clear
lane lines with the dynamic radar
cruise control operating, lane lines
and preceding and surrounding
vehicles are detected using the front
camera and radar sensor, and the
steering wheel is operated to main-
tain the vehicle’s lane position.

Use the this function only on highways and
expressways.
If the dynamic radar cruise control is not
operating, the function will not operate.
In situations where the lane lines are diffi-
cult to see or are not visible, such as when
in a traffic jam, support will be provided
using the path of preceding and surround-
ing vehicles.
If the system determines that the steering
wheel has not been operated for a certain
amount of time or the steering wheel is not
being firmly gripped, the driver will be
alerted and this function will be temporarily
canceled.

4-5. Using the driving support systems

According to the driving conditions, the operation and detectable objects of the
proactive driving assist will change as follows.

PDA (Proactive driving
assist)

When a detectable object
(

P.262) is detected, the proac-

tive driving assist operates the
brakes and steering wheel to help
prevent the vehicle from approach-
ing too close to the object.

WARNING

■

For safe use

Driving safely is solely the responsibility

of the driver.

●

The proactive driving assist is designed

to provide some assistance for regular

braking and steering operations, as

well as helping to prevent the vehicle

from approaching too close to a

detectable object. However, the scope

of this assistance is limited.

The driver should perform brake and

steering operations as necessary. Read

the following items carefully. Do not

overly rely on the proactive driving assist

and always drive carefully. (



P.264)

●

The proactive driving assist is not a sys-

tem which reduces the amount of

attention necessary for safe driving.

Even if the system is operating cor-

rectly, the surrounding conditions as

recognized by the driver and detected

by the system may differ. It is necessary

for the driver to pay attention, assess

risks, and ensure safety. Over-reliance

on this system to drive the vehicle

safely may lead to an accident result-

ing in death or serious injury.

●

Proactive driving assist is not a system

which allows for inattentive driving and

is not a system which assists in poor

visibility conditions. The driver is solely

responsible for paying attention to

their surroundings and driving safely.

WARNING

■

For safe use

Driving safely is solely the responsibility

of the driver. Pay careful attention to the

surrounding conditions in order to

ensure safe driving.

The FCTA system is a supplementary

system that informs the driver of vehicles

approaching from the left and right of the

front of the vehicle.

Over-reliance on this system may lead to

an accident resulting in death or serious

injury.

The details of the warning display may

differ from the actual traffic conditions.

Although the warning display will stop

being displayed after a certain amount of

time, this does not necessarily indicate

that there are no longer any vehicles or

pedestrians around your vehicle.

Dynamic radar cruise con-
trol

This dynamic radar cruise control
detects the presence of vehicles
ahead, determines the current
vehicle-to-vehicle distance, and
operates to maintain a suitable dis-
tance from the vehicle ahead. The
desired vehicle-to-vehicle distance
can be set by operating the vehi-
cle-to-vehicle distance switch.

Use the dynamic radar cruise con-
trol only on highways and express-
ways.

WARNING

■

For safe use

●

Driving safely is solely the responsibil-

ity of the driver. Do not overly rely on

this system, and pay careful attention

to the surrounding conditions in order

to ensure safe driving.

●

The dynamic radar cruise control pro-

vides driving assistance to reduce the

driver’s burden. However, there are

limitations to the assistance provided.

Read the following items carefully. Do

not overly rely on this system and always

drive carefully.
• Conditions under which the system

may not operate correctly:

P.279

●

Set the speed appropriately according

to the speed limit, traffic flow, road

conditions, weather conditions, etc.

The driver is responsible for confirm-

ing the set speed.

●

Even if the system is operating cor-

rectly, the condition of a preceding

vehicle as recognized by the driver

and detected by the system may differ.

Therefore, it is necessary for the driver

to pay attention, assess risks, and

ensure safety. Over-reliance on this

system to drive the vehicle safely may

lead to an accident resulting in death

or serious injury.

■

Precautions for the driving assist sys-

tems

Observe the following precautions, as

there are limitations to the assistance

provided by the system. Over-reliance

on this system may lead to an accident

resulting in death or serious injury.

●

Details of support provided for the

driver’s vision

The dynamic radar cruise control is only

intended to help the driver in determin-

ing the distance between the driver’s own

vehicle and a designated preceding vehi-

cle. It is not a system which allows for

careless or inattentive driving, and is not

a system which assists in poor visibility

conditions.
The driver must pay attention to their sur-

roundings,even when the vehicle stops.

●

Details of support provided for the

driver’s judgement

The dynamic radar cruise control deter-

mines whether the distance between the

driver’s own vehicle and a designated

preceding vehicle 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 vigi-

lant and to determine whether or not

there is a possibility of danger.

WARNING

●

Details of support provided for the

driver’s operation

The dynamic radar cruise control does

not include functions which will prevent

or avoid collisions with vehicles 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 safety.

■

Situations in which the dynamic radar

cruise control should not be used

Do not use the dynamic radar cruise

control in the following situations. As the

system will not be able to provide appro-

priate control, using it may lead to an

accident resulting in death or serious

injury.
