4-5. Using the driving support systems

Changing settings of the pre-collision system

■ Enabling/disabling the pre-collision system

The pre-collision system can be enabled/disabled on

(→P. 110)

of the multi-information display.

The system is automatically enabled each time the power switch is

turned to ON mode.

If the system is disabled, the

PCS warning light will turn on

and a message will be dis-

played on the multi-information

display.

■ Changing the pre-collision warning timing

The pre-collision warning timing can be changed on

(→P. 110)

of the multi-information display.

The operation timing setting is retained when the power switch is turned

off.

1

Far

The warning will begin to oper-

ate earlier than with the default

timing.

2

Middle

This is the default setting.

3

Near

The warning will begin to oper-

ate later than with the default

timing.

■ Pedestrian detection function*2

The pre-collision system detects pedestri-

ans based on the size, profile, and motion

of a detected object. However, a pedes-

trian may not be detected depending on

the surrounding brightness and the

motion, posture, and angle of the

detected object, preventing the system

from operating properly. (→P. 278)

*2: For countries/areas specified as Region B (→P. 268), the pedestrian detec-

tion function may not be available.

■ Cancelation of the pre-collision braking

If either of the following occurs while the pre-collision braking function is oper-

ating, it will be canceled:

● The accelerator pedal is depressed strongly.

● The steering wheel is turned sharply or abruptly.

4

■ Conditions under which the system may operate even if there is no pos-

sibility of a collision

● In some situations such as the following, the system may determine that

there is a possibility of a frontal collision and operate.

• When passing a vehicle or pedestrian*2

• When changing lanes while overtaking a preceding vehicle

• When overtaking a preceding vehicle that is changing lanes

• When overtaking a preceding vehicle

that is making a left/right turn

• When passing a vehicle in an oncom-

ing lane that is stopped to make a

right/left turn

4-5. Using the driving support systems

• When driving on a road where relative

location to vehicle ahead in an adja-

cent lane may change, such as on a

winding road

• When rapidly closing on a vehicle ahead

• If the front of the vehicle is raised or lowered, such as when the road sur-

face is uneven or undulating

• When approaching objects on the roadside, such as guardrails, utility

poles, trees, or walls

• When there is a vehicle, pedes-

trian*2, or object by the roadside at

the entrance of a curve

• When driving on a narrow path surrounded by a structure, such as in a

tunnel or on an iron bridge

• When there is a metal object (manhole cover, steel plate, etc.), steps, or a

protrusion on the road surface or roadside

• When a crossing pedestrian

approaches very close to the vehi-

cle*2

• When passing through a place with a

low structure above the road (low ceil-

ing, traffic sign, etc.)

• When passing under an object (bill-

board, etc.) at the top of an uphill road

• When rapidly closing on an electric toll gate barrier, parking area barrier,

or other barrier that opens and closes

• When using an automatic car wash

objects that may contact the vehicle,

such as thick grass, tree branches, or

a banner

• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead

• When driving through steam or smoke

• When there are patterns or paint on the road or a wall that may be mis-

taken for a vehicle or pedestrian*2

• When driving near an object that reflects radio waves, such as a large

truck or guardrail

• When driving near a TV tower, broadcasting station, electric power plant,

or other location where strong radio waves or electrical noise may be

present

*2: For countries/areas specified as Region B (→P. 268), the pedestrian

detection function may not be available.

4-5. Using the driving support systems

■ Situations in which the system may not operate properly

● In some situations such as the following, a vehicle may not be detected by

the radar sensor and camera sensor, preventing the system from operating

properly:

• If an oncoming vehicle is approaching your vehicle

• If a vehicle ahead is a motorcycle or bicycle

• When approaching the side or front of a vehicle

• If a preceding vehicle has a small rear end, such as an unloaded truck

• If a preceding vehicle has a low rear

end, such as a low bed trailer

• If a vehicle ahead is carrying a load which protrudes past its rear bumper

• If a vehicle ahead has extremely high

ground clearance

• If a vehicle ahead is irregularly shaped, such as a tractor or side car

• If the sun or other light is shining directly on a vehicle ahead

• If a vehicle cuts in front of your vehicle or emerges from beside a vehicle

• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving,

acceleration or deceleration)

• When suddenly cutting behind a preceding vehicle

• When a vehicle ahead is not directly

in front of your vehicle

• When driving through steam or smoke

• When driving in a place where the surrounding brightness changes sud-

denly, such as at the entrance or exit of a tunnel

• When a very bright light, such as the sun or the headlights of oncoming

traffic, shines directly into the camera sensor

• When the surrounding area is dim, such as at dawn or dusk, or while at

night or in a tunnel

• After the hybrid system has started the vehicle has not been driven for a

certain amount of time

• While making a left/right turn and for a few seconds after making a left/

• When driving on a hill

• If the radar sensor or camera sensor is misaligned

● In some situations such as the following, sufficient braking force may not be

obtained, preventing the system from performing properly:

• If the braking functions cannot operate to their full extent, such as when

the brake parts are extremely cold, extremely hot, or wet

• If the vehicle is not properly maintained (brakes or tires are excessively

worn, improper tire inflation pressure, etc.)

• When the vehicle is being driven on a gravel road or other slippery sur-

face

4-5. Using the driving support systems

LDA (Lane Departure Alert with steering

control)

Summary of functions

When driving on highways and freeways with white (yellow) lines, this

function alerts the driver when the vehicle might depart from its lane

and provides assistance by operating the steering wheel to keep the

vehicle in its lane.

The LDA system recognizes visi-

ble white (yellow) lines with the

camera sensor on the upper por-

tion of the windshield.

Functions included in LDA system

◆ Lane departure alert function

When the system determines

that the vehicle might depart

from its lane, a warning is dis-

played on the multi-information

display and the warning buzzer

sounds to alert the driver.

When the warning buzzer

sounds, check the surrounding

road situation and carefully

operate the steering wheel to

move the vehicle back to the

center of the lane.

283

◆ Steering control function

When the system determines

that the vehicle might depart

from its lane, the system pro-

vides assistance as necessary

by operating the steering wheel

in small amounts for a short

period of time to keep the vehi-

cle in its lane.

If the system detects that the

steering wheel has not been

operated for a fixed amount of

time or the steering wheel is not

being firmly gripped, a warning

is displayed on the multi-infor-

mation display and the warning

4

buzzer sounds.

◆ Vehicle sway warning function

When the vehicle is swaying or

appears as if it may depart from

its lane multiple times, the

warning buzzer sounds and a

message is displayed on the

multi-information display to alert

the driver.
