operation timing will return to the default setting (middle).

If the pre-collision warning timing is changed, emergency steering
assist timing will also be changed accordingly.
If late is selected, emergency steering assist would not operate in
case of an emergency.

Operational conditions for each pre-collision function

The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a detected object is high.
The system may not operate in the following situations:

• If a battery terminal has been disconnected and reconnected and then

the vehicle has not been driven for a certain amount of time

• If the shift lever is in R
• When the VSC OFF indicator is illuminated (only the pre-collision warning

function will be operational)
The operation speeds and operation cancellation for each function is
listed below.

Pre-collision warning

While the pre-collision warning function is operating, if the steering wheel is

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 detectable object, etc.
• When changing lanes while overtaking a detectable object, etc.

• When rapidly closing on a detectable object, etc.
• When approaching objects on the roadside, such as detectable objects,

guardrails, utility poles, trees, or walls

• When there are patterns or paint in front of your vehicle that may be mis-

taken for a detectable object

• When the front of your vehicle is hit by water, snow, dust, etc.

• When approaching a detectable

object in an adjacent lane or on the
roadside, such as when changing the
course of travel or driving on a wind-
ing road

• When overtaking a detectable object

that is changing lanes or making a
right/left turn

Situations in which the system may not operate properly

●

In some situations such as the following, an object may not be detected by
the radar sensor and front camera, preventing the system from operating
properly:
• When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudden swerv-

ing, acceleration or deceleration)

• When your vehicle approaches a detectable object rapidly

• When a detectable object is near a wall, fence, guardrail, manhole cover,

vehicle, steel plate on the road, etc.

• When a detectable object is under a structure
• When part of a detectable object is hidden by an object, such as large

baggage, an umbrella, or guardrail

• When there are many things which can reflect the radio waves of the

radar in the vicinity (tunnels, truss bridges, gravel roads, snow covered
road that have tracks, etc.)

• When there is an effect on the radio waves to the radar that is installed on

another vehicle

• When multiple detectable objects are close together
• If the sun or other light is shining directly on a detectable object
• When a detectable object is a shade of white and looks extremely bright
• When a detectable object appears to be nearly the same color or bright-

ness as its surroundings

• If a detectable object cuts or suddenly emerges in front of your vehicle
• When the front of your vehicle is hit by water, snow, dust, etc.
• When a very bright light ahead, such as the sun or the headlights of

oncoming traffic, shines directly into the front camera

• When approaching the side or front of a vehicle ahead
• If a vehicle ahead is a motorcycle

• While making a right/left turn, when

an oncoming vehicle turns right/left in
front of your vehicle

• When a detectable object is not

directly in front of your vehicle

In some situations such as the following, sufficient braking force or steering
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.)

4-5. Using the driving support systems

While driving on a road with clear white (yellow) lane lines, the LTA
system warns the driver if the vehicle may deviate from the current
lane or course

, and also can slightly operate the steering wheel to

help avoid deviation from the lane or course

. Also, while the dynamic

radar cruise control with full-speed range or dynamic radar cruise con-
trol is operating, this system will operate the steering wheel to main-
tain the vehicle’s lane position.
The LTA system recognizes white
(yellow) lane lines or a course

using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.

: Boundary between asphalt and the side of the road, such as grass, soil, or

a curb

LTA (Lane Tracing Assist)

Summary of functions

WARNING

■

Before using LTA system

●

Do not rely solely upon the LTA system. The LTA 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 paying careful attention to the surround-
ing 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.

■

Situations unsuitable for LTA system

In the following situations, use the LTA switch to turn the system off. Failure
to do so may lead to an accident, resulting in death or serious injury.

●

Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.

●

Vehicle is driven on a snow-covered road.

●

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

●

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

●

When the tires have been excessively worn, or when the tire inflation pres-
sure is low.

●

During emergency towing

■

Preventing LTA 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.
