WARNING

■Toyota Safety Sense 2.0

The Toyota Safety Sense 2.0 is

designed to operate under the

assumption that the driver will

drive safely, and is designed to

help reduce the impact to the

occupants and the vehicle in the

case of a collision or assist the

driver in normal driving condi-

tions.

recognition accuracy and control

performance that this system can

provide, do not overly rely on this

system. The driver is always

responsible for paying attention to

the vehicle’s surroundings and

driving safely.

Situation Actions

When the area around a camera is

covered with dirt, moisture (fogged

up, covered with condensation, ice,

etc.), or other foreign matter

Using the wiper and A/C function,

remove the dirt and other attached

matter. (P.349)

When the temperature around the

front camera is outside of the opera-

tional range, such as when the vehi-

cle is in the sun or in an extremely

cold environment

If the front camera is hot, such as

after the vehicle had been parked in

the sun, use the air conditioning sys-

tem to decrease the temperature

around the front camera.

If a sunshade was used when the

vehicle was parked, depending on its

type, the sunlight reflected from the

surface of the sunshade may cause

the temperature of the front camera

to become excessively high.

If the front camera is cold, such as

after the vehicle is parked in an

extremely cold environment, use the

air conditioning system to increase

the temperature around the front

camera.

The area in front of the front camera

is obstructed, such as when the

hood is open or a sticker is attached

to the part of the windshield in front

of the front camera.

Close the hood, remove the sticker,

etc. to clear the obstruction.

When “Pre-Collision System

Unavailable” is displayed.

LTA (Lane Tracing

Assist)

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 con-

trol with full-speed range

P.291 is operating, this sys-

tem will operate the steering

wheel to maintain the vehi-

cle’s lane position.

The LTA system recognizes

white (yellow) lane lines or a

course*using the front cam-

era. Additionally, 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

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 not using the LTA sys-

tem, use the LTA switch to turn

the system off.

■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.
