• If a vehicle ahead is a child sized

bicycle, is carrying a large load, is

carrying an extra passenger, or

has an unusual shape (bicycles

equipped with a child seat, tan-

dem bicycles, etc.)

• If a pedestrian or bicycle is shorter

than approximately 3.2 ft. (1 m) or

taller than approximately 6.5 ft. (2

m).

• When the silhouette of a pedes-

trian or bicycle is unclear (such as

when they are wearing a raincoat,

long skirt, etc.)

• When a pedestrian or bicycle is

bending forward or squatting

• When a pedestrian or bicycle is

moving at high speed

• When a pedestrian is pushing a

stroller, wheelchair, bicycle or

other vehicle

• When a detectable object blends

in with the surrounding area, such

as when it is dim (at dawn or dusk)

or dark (at night or in a tunnel)

• When the vehicle has not been

driven for a certain amount of time

after the engine was started

• While turning left/right or a few

seconds after turning left/right

• While driving around a curve and

a few seconds after driving around

a curve

• When turning left/right and an

oncoming vehicle is driving in a

lane 3 or more lanes from the

vehicle

• When turning left/right and the

direction of the vehicle differs

greatly from the direction traffic

flows in the oncoming lane

• When turning left/right and

approaching a pedestrian which

was traveling in the same direc-

tion as the vehicle and continues

straight

●

In addition to the preceding, in

certain situations, such as the fol-

lowing, the emergency steering

assist may not operate properly:

• When a detectable object is too

close to the vehicle

• When there is insufficient space to

perform evasive steering maneu-

vers or an obstruction exists in the

evasion direction

• When there is an oncoming vehi-

cle

The pre-collision system can
be enabled/disabled through

The system is enabled each time
the engine switch is turned to ON.



The pre-collision setting can
be changed on the customize
settings. (

P.391)



When the pre-collision warn-
ing timing is changed, the
emergency steering assist
(excluding the active steering
function) timing will also be
changed.
When "Later" is selected, the
emergency steering assist
(excluding the active steering
function) will not operate in
most cases.



When the dynamic radar
cruise control is operating, the
pre-collision warning will
operate at the “Earlier” timing,
regardless of the user setting.



When driving on a road with
clear lane lines with the
dynamic radar cruise control
operating, lane lines and pre-
ceding and surrounding vehi-
cles are detected using the
front camera and radar sen-
sor, and the steering wheel is
operated to maintain the vehi-
cle’s lane position.

Use 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 difficult to see or are not visible,
such as when in a traffic jam, sup-
port will be provided using the path
of preceding and surrounding vehi-
cles.
If the system determines that the
steering wheel has not been oper-
ated for a certain amount of time or
the steering wheel is not being
firmly gripped, the driver will be
alerted via a display and this func-
tion will be temporarily canceled.
If the steering wheel is firmly
gripped, the function will begin
operating again.

depart from its lane, the driver
will be alerted via a display

When the buzzer sounds, check
the area around the vehicle and
carefully operate the steering wheel
to move the vehicle back to the
center of the lane.

WARNING

■

Before using the LTA system

●

Do not overly rely on the LTA

system. The LTA system is not a

system which provides auto-

mated assistance in driving and

it is not a system which reduces

the amount of attention neces-

sary for safe driving. The driver

is solely responsible for paying

attention to their surroundings

and operating the steering

wheel as necessary to ensure

safety. Also, the driver is

responsible for taking adequate

breaks when fatigued, such as

when driving for a long time.

●

Failure to perform appropriate

driving operations and pay care-

ful attention may lead to an

accident.

●

When not using the LTA system,

turn it off using the LTA switch.

179

4-5. Using the driving support systems

ing

the following conditions are met:

●

The LTA system detects lane lines

or the path of preceding or sur-

rounding vehicles (except when

the preceding vehicle is small,

such as a motorcycle).

●

The dynamic radar cruise control

is operating.

●

The lane width is approximately

10 to 13 ft. (3 to 4 m).

●

The turn signal lever is not being

operated.

●

The vehicle is not being driven

around a sharp curve.

●

The vehicle is not accelerating or

decelerating more than a certain

amount.

●

The steering wheel is not being

turned with a large force.

●

The hands off steering wheel

warning (



P.179) is not operat-

ing.

●

The vehicle is being driven in the

center of a lane.

■

Temporary cancelation of func-

tions

●

When the operating conditions are

no longer met, a function may be

temporarily canceled. However,

when the operation conditions are

met again, operation of the func-

tion will automatically be restored.

(



P.178)

●

If the operating conditions of a

function are no longer met while

the function is operating, a buzzer

may sound to indicate that the

function has been temporarily

canceled.

●

The steering assist operation of

the function can be overridden by

the steering wheel operation of

the driver.

■

Lane departure warning func-

tion when the LTA is operating

●

Even if the LDA warning method is

changed to vibration of the steer-

ing wheel, if the vehicle deviates

from the lane while the LTA is

operating, the warning buzzer will

sound to alert the driver.

●

If steering wheel operation equiv-

alent to that necessary for a lane

change is detected, the system

will determine the vehicle is not

deviating from the lane and the

warning will not operate.

■

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 multi-information display to warn

the driver. If the system detects that

the steering wheel is held, the warn-

ing will be canceled. When using the

system, make sure to grip the steer-

ing 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 function is operat-

ing

If no operations are detected for a

certain amount of time, a buzzer will

sound, the warning will operate, and

the function will be temporarily can-

celed. This warning may also oper-

ate if the driver only operates

steering wheel a small amount con-

tinuously.
Depending on the condition of the

vehicle, handle control condition

and road surface, the warning func-

tion may not operate.

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-

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.

PDA (Proactive driv-

ing assist)

When a detectable object
(



P.188) 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.189)

●

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.
