■

Object detection function

The system detects objects based

on their size, profile, motion, etc.

However, an object may not be

detected depending on the sur-

rounding brightness and the motion,

posture, and angle of the detected

object, preventing the system from

operating properly. (

The illustration shows an image of

detectable objects.

■

Conditions under which the

system may operate even if

there is no possibility of a colli-

sion

In some situations such as the fol-

lowing, the system may determine

that there is a possibility of a fron-

tal collision and operate.

• When passing a detectable object,

etc.

taking a detectable object, etc.

• When approaching a detectable

object in an adjacent lane or on

4-5. Using the driving support systems

●

In addition to the above, in some

situations, such as the following,

the emergency steering assist

may not operate.

• When the white (yellow) lane lines

are difficult to see, such as when

they are faint, diverging/merging,

or a shadow is cast upon them

tern on the road surface, such as

due to road repairs

near the centerline of the vehicle

• When the target is too close

• When there is insufficient safe or

unobstructed space for the vehicle

to be steered into

• If oncoming vehicle is present

• If VSC function is operating

●

In some situations such as the fol-

lowing, 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 main-

tained (brakes or tires are exces-

sively worn, improper tire inflation

pressure, etc.)

trailer or another vehicle

• When your vehicle is lifted up

■

If VSC is disabled

●

If VSC is disabled (



P.384), the

pre-collision brake assist and pre-

collision braking functions are also

disabled.

●

The PCS warning light will turn on

and “VSC Turned OFF Pre-Colli-

sion Brake System Unavailable”

will be displayed on the multi-

information display.

261

4-5. Using the driving support systems

ing

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

, and also can

slightly operate the steering
wheel to help avoid deviation
from the lane. Also, while the
dynamic radar cruise control
with full-speed range is operat-
ing, this system will operate the
steering wheel to maintain the
vehicle’s lane position.
The LTA system recognizes
white (yellow) lane lines

using

the front camera. Additionally, it
detects preceding vehicles
using the front camera and
radar.

: May recognize the boundaries

between the asphalt and the side
of the road, such as grass, soil, or
the curb, to be road lanes

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 automatically drive the vehi-

cle 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 atten-

tion to the surrounding condi-

tions 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 care-

ful attention may lead to an

accident, resulting in death or

serious injury.

●

When connecting a trailer which

can be connected with Toyota’s

official TBC ECU, the lane cen-

tering function will be disabled

automatically when LTA detects

a trailer connection.

When other trailer is connected,

turn off the lane centering func-

tion if a trailer is connected and

it is not automatically disabled.

After trailer disconnect and

power switch is turned off, lance

centering function can be turned

on.

262

4-5. Using the driving support systems

WARNING

●

This vehicle has Automatic

Trailer Detection feature that

can detect certain trailers under

certain conditions. After trailer is

detected, lane centering func-

tion will be disabled. In certain

conditions, there is a possibility

of falsely detecting trailer when

there is no actual trailer. In that

case, lane centering function

will be disabled. To activate lane

centering function, turn power

switch to off and then turn it on

again.

●

Following scenes has possibility

of false detection of trailer:

Crowded environments such as

parking lots or camping

grounds, closely following vehi-

cles such traffic jam, drive

through, parallel parking, etc.

●

Do not use the lane centering

system and steering assist func-

tion when the vehicle is lifted

unless using a Toyota official lift

up kit up to 4 in. (101 mm),

including tire height. Aftermar-

ket lift kits may degrade system

performance.

■

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 sur-

face which is slippery due to

rainy weather, fallen snow,

freezing, etc.

●

Vehicle is driven on a snow-cov-

ered road.

●

White (yellow) lines are difficult

to see due to rain, snow, fog,

dust, etc.

●

Vehicle is driven in a temporary

lane or restricted lane due to

construction work.

●

Vehicle is driven in a construc-

tion zone.

●

A spare tire, tire chains, etc.,

are equipped.

●

When the tires have been

excessively worn, or when the

tire inflation pressure is low.

●

When your vehicles is towing a

trailer or another vehicle, except

when the following condition is

met.

• When the other vehicle is a

trailer properly attached and

connected to Toyota’s official

TBC ECU. (



P.198)

●

When the vehicle is lifted up,

except in the following cases.

• When using a Toyota official lift

kit up to 4 in. (101 mm), includ-

ing tire height. Aftermarket lift

kits may degrade system perfor-

mance.

■

Preventing LTA system mal-

functions and operations per-

formed by mistake

●

Do not modify the headlights or

place stickers, etc., on the sur-

face 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.

Lane departure alert func-
tion

When the system determines
that the vehicle might depart
from its lane

, a warning is dis-

played on the multi-information
display, and either a warning
buzzer will sound or the steering
wheel will vibrate to alert the
driver.

When the warning buzzer sounds
or the steering wheel vibrates,
check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane.
When the system determines that
the vehicle might depart from its
lane and that the possibility of a col-
lision with an overtaking vehicle in
the adjacent lane is high, the lane
departure alert will operate even if
the turn signals are operating.

: May recognize the boundaries

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

■

Steering assist 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.

When the system determines that
the vehicle might depart from its
lane and that the possibility of a col-
lision with an overtaking vehicle in
