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.

■

Warning operation after preced-

ing vehicle deceleration assis-

tance has ended

After preceding vehicle decelera-

tion assistance has ended, if the

driver does not operate the brake

pedal or accelerator pedal and the

vehicle approaches the preceding

vehicle, the display will flash and a

buzzer will sound to urge the driver

to decelerate. If the system deter-

mines that the driver is operating the

brake pedal or accelerator pedal,

the warning will be canceled.

Dynamic radar cruise

control

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

Use the dynamic radar
cruise control only on high-
ways and expressways.

WARNING

■

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.

Read the following items carefully.

Do not overly rely on this system

and always drive carefully.

Conditions under which the sys-

tem may not operate correctly:



P.199

●

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

194

4-5. Using the driving support systems

WARNING

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.

Constant speed cruising:
When there are no vehicles ahead

The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle
speed display will blink and a buzzer will sound.

Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle
speed is detected

When a vehicle is detected driving ahead of your vehicle, the vehicle auto-
matically decelerates and if a greater reduction in vehicle speed is neces-
sary, the brakes are applied (the stop lights will come on at this time). The
vehicle is controlled to maintain the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the preceding vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach warning will sound.

Acceleration
When there are no longer any preceding vehicles driving slower
than the set vehicle speed

The vehicle accelerates until the set vehicle speed is reached and then
resumes constant speed cruising.

Starting off:
If a preceding vehicle stops, the vehicle will also stop (controlled
stop). After the preceding vehicle starts off, pressing the “RES”
switch or depressing the accelerator pedal will resume follow-up
cruising (start off operation). If a start off operation is not per-

turn signal lever is operated away
from the passing lane. (e.g. The
vehicle was manufactured for a
right-hand traffic location, but is
being driven in a left-hand traffic
location. The vehicle may acceler-
ate when the turn signal lever is
operated to the right.)
If your vehicle is being driven at
approximately 50 mph (80 km/h) or

Emergency Driving

Stop System

The emergency driving stop
system is a system which
automatically decelerates
and stops the vehicle within
its lane if the driver
becomes unable to continue
driving the vehicle, such as
if they have suffered a medi-
cal emergency, etc.

During LTA (Lane Tracing
Assist) control, if the sys-
tem does not detect driving
operations, such as if the
driver is not holding the
steering wheel, and deter-
mines the driver is not
responsive, the vehicle will
be decelerated and stopped
within its current lane to
help avoid a collision or
reduce the impact of a colli-
sion.

WARNING

■

For safe use

●

Driving safely is solely the

responsibility of the driver. Pay

careful attention to the sur-

rounding conditions in order to

ensure safe driving. The emer-

gency driving stop system is

designed to provide support in

an emergency where it is diffi-

cult for the driver to continue

driving, such as if they have had

a medical emergency. It is not

designed to support driving

while drowsy or in poor physical

health, or inattentive driving.

●

Although the emergency driv-

ing stop system is designed to

decelerate the vehicle within its

lane to help avoid or help

reduce the impact of a collision

if the system determines that it

is difficult for the driver to con-

tinue driving, its effectiveness

may change according to vari-

ous conditions. Therefore, it

may not always be able to

achieve the same level of per-

formance. Also, if the operating

conditions are not met, this

function will not operate.

●

After the emergency driving

stop system operates, if driving

becomes possible again, imme-

diately begin driving again or, if

necessary, park the vehicle on

the shoulder of the road and set

a warning reflector and flare to

warn other drivers of your

stopped vehicle.

●

After this system operates, pas-

sengers should attend to the

driver as necessary and take

appropriate hazard prevention

measures, such as moving to a

place where safety can be

ensured, such as the shoulder

of the road or behind a guard-

rail.

●

This system detects the condi-

tion of the driver through the

operation of the steering wheel.

This system may operate if the

driver is aware but intentionally

and continuously does not oper-

ate the vehicle. Also, the system

may not operate if it cannot

determine that the driver is not

responsive, such as if they are

leaning on the steering wheel.

Summary of the system

205

4-5. Using the driving support systems

ing

Through control state “warning
phase 1” and “warning phase 2”,
the system determines if the
driver is aware and responsive
while outputting a warning and
controlling the vehicle speed. If
the system determines the
driver is not responsive, it will
operate in control state “deceler-
ation stop phase” and “stop hold
phase” and decelerate and stop
the vehicle. It will then operate
continuously in “stop hold
phase”.

■

Operating conditions

This system operates when all of

the following conditions are met:

●

When the LTA is on

●

When the vehicle speed is

approximately 30 mph (50 km/h)

or more

■

Operation cancelation condi-

tions

In the following situations, system

operation will be canceled:

●

When LTA control has been can-

celed (the LTA switch has been

pressed, etc.)

●

When the dynamic radar cruise

control has been canceled

●

When driver operations are

detected (the steering wheel is

held, the brake pedal, accelerator

pedal, parking brake, hazard light

switch, or turn signal lever is oper-

ated)

●

When the driving assist switch is

pressed while in the stop and hold

●

When the engine switch has been

turned from ON to off

■

LTA control when operation is

canceled

When emergency driving stop sys-

tem operation is canceled, LTA con-

trol may also be canceled.

If driving operations are not
detected after the hands off
steering wheel warning oper-
ates, a buzzer will sound inter-
mittently and a message will be
displayed to warn the driver, and
the system will judge if the driver
is responsive or not. If driving
operations, such as holding the
steering wheel, are not per-
formed within a certain amount
of time, the system will enter
warning phase 2.

After entering warning phase 2,
a buzzer will sound in short
intervals and a message will be
displayed to warn the driver, and
the vehicle will slowly deceler-
ate. If driving operations, such
as holding the steering wheel,
are not performed within a cer-
tain amount of time, the system
will determine that the driver is
not responsive and enter the
deceleration stop phase.

The audio system will be muted
until the driver becomes respon-
sive.
