Enabling/disabling the pre-
collision system

The pre-collision system can be 
enabled/disabled on 

 

(

P.573) of the multi-informa-

tion display.

The system is automatically 
enabled each time the engine 
switch is turned to ON.

If the system is disabled, the 
PCS warning light will turn on 
and a message will be displayed 
on the multi-information display.

“Pre-Collision System OFF”

Changing the pre-collision 
warning timing

The pre-collision warning timing 
can be changed on 

 

(

P.573) of the multi-informa-

tion display.

The warning timing setting is 
retained when the engine switch is 
turned off. However, if the pre-colli-
sion system is disabled and re-
enabled, the operation timing will 
return to the default setting (mid-
dle).

If the pre-collision warning tim-
ing is changed, emergency 
steering assist timing will also 
be changed accordingly.
If late is selected, emergency 
steering assist would not oper-
ate 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 cancelation for each function is listed 

below.

Pre-collision warning

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

operated heavily or suddenly, the pre-collision warning may be canceled.

Emergency steering assist

When the turn signal lights are flashing, emergency steering assist will not 
operate in case of an emergency.
The emergency steering assist will be disabled automatically when the sys-
tem judges that a trailer is connected.

If any of the following occur while the emergency steering assist function is 

operating, it will be canceled:
• The accelerator pedal is depressed strongly.

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. (

P.244)

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.

• When changing lanes while over-

taking a detectable object, 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 winding road

• When rapidly closing on a detect-

able object, etc.

• When approaching objects on the 

roadside, such as detectable 

objects, guardrails, utility poles, 

trees, or walls

• When there is a detectable object 

or other object by the roadside at 

the entrance of a curve

• When there are patterns or paint 

in front of your vehicle that may be 

mistaken for a detectable object

• When the front of your vehicle is 

hit by water, snow, dust, etc.

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 function if a 

trailer is connected and it is not 

automatically disabled.After 

trailer disconnect and power 

switch is turned off, lance cen-

tering function can be turned on.

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. n that 

case, lane centering function 

will be disabled. To activate lane 

centering function, turn power 

switch to off and then turn it on 

again.

248

4-5. Using the driving support systems

WARNING

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.

TBC ECU. (

P.186)

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.

Conditions in which functions 

may not operate properly

In the following situations, the 

functions may not operate prop-

erly and the vehicle may depart 

from its lane. Drive safely by 

always paying careful attention to 

your surroundings and operate 

the steering wheel to correct the 

path of the vehicle without relying 

solely on the functions.
