mometer or speedometer tester, or when using an on vehicle wheel bal-

ancer

● When a strong impact is applied to the front bumper or front grille, due to

an accident or other reasons

mation display as following:

The operation timing setting is retained when the engine switch is

turned off.

1

4-5. Using the driving support systems

■ Pedestrian detection function

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. 245)

■ Cancelation of the pre-collision braking

If either of the following occur 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.

4-5. Using the driving support systems

243

sibility of a collision

there is a possibility of a frontal collision and operate.

• When passing a vehicle or pedestrian

• When changing lanes while overtaking a preceding vehicle

• When overtaking a preceding vehicle that is changing lanes

ing lane that is stopped to make a

right/left turn

location to vehicle ahead in an adja-

cent lane may change, such as on a

LDA (Lane Departure Alert)

Summary of functions

When driving on roads with white (yellow) lines, this function alerts the

driver when the vehicle might depart from its lane.

The LDA system recognizes visi-

ble white (yellow) lines with the

camera sensor on the upper por-

tion of the windshield.

4

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.

: If equipped

◆ Vehicle sway warning

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.

251

WARNING

■ Before using LDA system

Do not rely solely upon the LDA system. The LDA system does not auto-

matically drive the vehicle or reduce the amount of attention that must be

paid to the area in front of the vehicle. The driver must always assume full

responsibility for driving safely by always paying careful attention to the sur-

rounding conditions and operating the steering wheel to correct the path of

the vehicle. Also, the driver must take adequate breaks when fatigued, such

as from driving for a long period of time.

Failure to perform appropriate driving operations and pay careful attention

may lead to an accident, resulting in death or serious injury.

■ To avoid operating LDA system by mistake

When not using the LDA system, use the LDA switch to turn the system off.

■ Situations unsuitable for LDA system

Do not use the LDA system in the following situations.

The system may not operate properly and lead to an accident, resulting in

4

death or serious injury.

● A spare tire, tire chains, etc., are equipped.

● Objects or patterns that could be mistaken for white (yellow) lines are

present on the side of the road (guardrails, curbs, reflective poles, etc.).

● Vehicle is driven on a snow-covered road.

●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.

● Asphalt repair marks, white (yellow) line marks, etc., are present due to

road repair.

● Vehicle is driven in a temporary lane or restricted lane due to construction

work.

● Vehicle is driven in a construction zone.

252

4-5. Using the driving support systems

WARNING

■ Preventing LDA system malfunctions and operations performed by

mistake

● Do not modify the headlights or place stickers, etc., on the surface of the

lights.

● Do not modify the suspension, etc. If the suspension, etc., needs to be

replaced, contact your Toyota dealer.

● Do not install or place anything on the hood or grille. Also, do not install a

grille guard (bull bars, kangaroo bar, etc.).

● If your windshield needs repairs, contact your Toyota dealer.
