Operation of the lane departure

alert function/lane departure

prevention function

●

Depending on the vehicle speed,

road conditions, lane departure

angle, etc., operation of the lane

departure prevention function may

not be felt or the function may not

operate.

●

Depending on the conditions, the

warning buzzer may operate even

if vibration is selected through a

customize setting.

●

If a course

is not clear or straight,

the lane departure alert function or

lane departure prevention function

may not operate.

●

The lane departure alert function

or lane departure prevention func-

tion may not operate if the system

judges that the vehicle is inten-

tionally being steered to avoid a

pedestrian or parked vehicle.

●

Vehicles with BSM: It may not be

possible for the system to judge if

there is danger of a collision with a

vehicle in an adjacent lane.

●

The steering assist operation of

the lane departure prevention

function can be overridden by the

steering wheel operation of the

driver.

: Boundary between the asphalt

and grass, soil, etc., or structures,
such as a curb, guardrail, etc.

■

Hands off steering wheel warn-

ing operation

In the following situations, a mes-

sage urging the driver to operate the

steering wheel and an icon will be

displayed and a buzzer will sound to

warn the driver. When using the sys-

tem, make sure to grip the steering

wheel firmly, regardless of whether

the warning is operating or not.

●

When the system determines that

the driver is not securely holding

the steering wheel, or the steering

wheel is not being operated when

the steering assist operation of the

lane departure prevention function

is operating

The length of time that the warning

buzzer operates will become longer

as the frequency of the steering

assist operating increases. Even if

the system judges that the steering

wheel has been operated, the warn-

ing buzzer will sound for a certain

amount of time.

■

Break suggestion function

If the vehicle is swaying, a message

will be displayed and a warning

buzzer will sound to urge the driver

to take a break.

Depending on the condition of the

vehicle and road surface, the break

suggestion function may not oper-

ate.

solely responsible for paying

attention to their surroundings

and operating the steering wheel

as necessary to ensure safety.

PDA (Proactive driv-

ing assist)

When a detectable object
(



P.229) is detected, the

proactive driving assist
operates the brakes and
steering wheel to help pre-
vent the vehicle from
approaching too close to
the object.

WARNING

■

For safe use

Driving safely is solely the respon-

sibility 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 lim-

ited.

The driver should perform brake

and steering operations as neces-

sary. Read the following items

carefully. Do not overly rely on the

proactive driving assist and

always drive carefully.(



P.230)

●

The proactive driving assist is

not a system which reduces the

amount of attention necessary

for safe driving. Even if the sys-

tem is operating correctly, the

surrounding conditions as rec-

ognized by the driver and

detected by the system may dif-

fer. It is necessary for the driver

to pay attention, assess risks,

and ensure safety. Over-reli-

ance on this system to drive the

vehicle safely may lead to an

accident resulting in death or

serious injury.

●

Proactive driving assist is not a

system which allows for inatten-

tive 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.

Hands off steering wheel warn-

ing operation

In the following situations, a mes-

sage urging the driver to grip the

steering wheel and the icon shown

in the illustration will be displayed on

the display to warn the driver. If the

system detects that the steering

wheel is held, the warning will be

canceled. When using the system,

make sure to grip the steering wheel

firmly, regardless of whether the

warning is operating or not.

●

When the system determines the

driver is not holding the steering

wheel while the lane centering

function is operating

If no operations are detected for a
certain amount of time, a buzzer will
sound, the warning will operate.
This warning may also operate if the
driver only operates steering wheel
a small amount continuously.

After preceding vehicle decelera-

tion assistance has ended, if the

driver does not operate the brake

pedal or accelerator pedal and the

RSA (Road Sign

Assist)

The RSA system detects
specific road signs using
the front camera and/or nav-

able) and warns the driver
via displays and buzzers.

WARNING

■

For safe use

●

Driving safely is solely the

responsibility of the driver. Pay

careful attention to the sur-

ensure safe driving.

●

Do not rely solely upon the

RSA. The RSA assists the

driver by providing road sign

information, but it is not a

replacement for the driver’s own

vision and awareness. Driving

safely is solely the responsibility

of the driver. Pay careful atten-

For safe use

●

Driving safely is solely the

responsibility 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 con-

trol provides driving assistance

to reduce the driver’s burden.

However, there are limitations to

the assistance provided.

WARNING

●

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

correctly, the condition of a pre-

ceding 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 systems

Observe the following precau-

tions, as there are limitations to

the assistance provided by the

system. Over-reliance on this sys-

tem 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 determining 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 surroundings, even when the

vehicle stops.

●

Details of support provided for

the driver’s judgement

The dynamic radar cruise control

determines whether the distance

between the driver’s own vehicle

and a designated preceding vehi-

cle 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.

●

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 vehi-

cle. 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 situ-

ations. As the system will not be

able to provide appropriate con-

trol, using it may lead to an acci-

dent resulting in death or serious

injury.
