NOTICE

●

Under the conditions listed 

below, it will become more diffi-

cult for the system to detect the 

vehicle in front, motorcycles, 

bicycles, pedestrians and obsta-

cles on the road, and lane mark-

ers. Also, EyeSight may 

temporarily stop operating. 

However, the temporary stop 

will be canceled once these 

conditions have improved and 

the vehicle is driven for a short 

period of time.

• Bad weather (for example 

heavy rain, a blizzard or thick 

fog). In particular, the system is 

more likely to temporarily stop 

operating when there is an oil 

film adhering to the windshield, 

a glass coating has been 

applied, or poorly performing 

wipers are used.

• Strong light is coming from the 

front (sunlight or headlight 

beams of oncoming traffic, etc.).

• The windshield washer is in 

use.

• Raindrops, water drops, or dirt 

on the windshield are not wiped 

off sufficiently.

• The windshield has become 

fogged, scratched or smeared, 

or snow, dirt ,dust or frost has 

adhered to it, or it is otherwise 

affected. These will reduce the 

stereo camera’s field of view. 

Also, light is reflecting off the 

dirt, etc.

• The vehicle is tilted at an 

extreme angle due to loaded 

cargo or other factors.

• Visibility is poor due to sand, 

smoke or water vapor blowing in 

the wind, or the front vision is 

obscured due to water 

splashes, snow, dirt or dust stir 

up generated by the vehicle in 

front or oncoming traffic.

• The stereo camera’s field of 

view is obstructed.

• Through the entrance or exit of 

a tunnel

• The rear aspect of the vehicle in 

front is low, small or irregular 

(for example a low bed trailer, 

etc.).

• The obstacle is a fence, a wall 

or a shutter, etc. with a uniform 

pattern (a striped pattern, brick, 

etc.) or with no pattern in front.

• The obstacle is a wall or door 

made of glass or a mirror in 

front.

• Driving at night or in a tunnel 

when there is a vehicle in front 

that does not have its taillights 

on

• Driving through a banner or flag, 

low branches on a tree or 

thick/tall vegetation

• On steep uphill or downhill 

grades

• The stereo camera is 

obstructed by a hand, etc. (If 

even one of the lenses is 

obstructed, the system does not 

operate properly.)

• It is completely dark and no 

objects are detected.

• The area around the vehicle has 

a uniform color (such as when 

completely covered in snow, 

etc.).

NOTICE

• Accurate detection is not possi-

ble due to reflections in the 

windshield.

●

Under the conditions listed 

below, EyeSight may temporar-

ily stop operating. If this occurs, 

EyeSight will resume operating 

when the conditions improve.

• The temperature inside the 

vehicle is high, such as after the 

vehicle was left in bright sun-

shine, or the temperature inside 

the vehicle is low, such as after 

the vehicle was left in an 

extremely cold environment.

• Immediately after the engine 

starts

●

Under the conditions listed 

below, it is difficult to recognize 

vehicles in front, motorcycles, 

pedestrians, obstacles on the 

road, traffic lanes, etc. Also, the 

EyeSight system may temporar-

ily stop operating. If the Eye-

Sight system repeatedly stops 

operating several times, con-

tact a Toyota dealer and have 

the system inspected.

• The stereo camera lenses are 

smeared such as from finger-

prints.

• The stereo camera has become 

misaligned due to a strong 

impact.

●

When there is a malfunction in 

the EyeSight system, turn off 

Pre-Collision Braking System 

(



P.189) and Lane Departure 

Warning (



P.221), and stop 

using Adaptive Cruise Control 

and Conventional Cruise Con-

trol. Contact a Toyota dealer 

and have the system inspected.

●

When the slip indicator is illumi-

nated, Pre-Collision Braking 

System may not operate prop-

erly. If the slip indicator is illumi-

nated, turn off Pre-Collision 

Braking System. Also, do not 

use Adaptive Cruise Control or 

Conventional Cruise Control.

NOTICE

●

The stereo camera monitors 

and detects smears or blurs on 

the front of the camera. How-

ever, detection is not 100% 

accurate.

Under certain conditions, the 

function may fail to detect 

smears or blurs on the front of 

the stereo camera accurately. In 

addition, this function may not 

detect that there is snow or ice 

on the windshield close to the 

stereo camera. In such condi-

tions, be sure to keep the wind-

shield clean at all times 
(indicated by 

 ). Otherwise 

the system may not operate cor-

rectly. When this function 

detects that the front of the ste-

reo camera is smeared or 

blurred, no EyeSight functions 

can be activated except for 

Conventional Cruise Control.

●

The stereo camera lenses are 

precision components. Always 

observe the following precau-

tions especially when handling 

them.

• Never touch the stereo camera 

lenses, and do not attempt to 

wipe or clean the lenses. Doing 

so could damage or soil the 

lens, and lead to improper sys-

tem performance. If you ever 

touch a lens for any reason, be 

sure to contact your Toyota 

dealer.

• When cleaning the windshield, 

cover the front of the camera 

casing with paper that does not 

collect dust, such as copy 

paper. Affix the paper to prevent 

glass cleaner from getting on 

the camera lenses. At this point, 

make sure that the tape’s adhe-

sive surface does not come in 

contact with the windshield or 

the lens. Be sure to remove the 

paper after cleaning.

• When having the inside of wind-

shield cleaned at a service sta-

tion, etc., be sure to request that 

the attendant covers the cam-

era covers before washing the 

vehicle.

• Do not subject the stereo cam-

era to a strong impact.

• Do not remove or disassemble 

the stereo camera.

• Do not change the positions 

where the stereo camera is 

installed or modify any of the 

surrounding structures.

●

Do not install an interior rear-

view mirror other than a genuine 

Toyota rearview mirror (such as 

a wide-type mirror) and the sun 

visor. Also, use the rearview 

mirror so that it does not 

obstruct the stereo camera. 

Failure to do so may affect the 

stereo camera’s field of view 

and could prevent the EyeSight 

system from functioning prop-

erly.

EyeSight includes the following 
functions.

■

Pre-Collision Braking Sys-
tem

This function uses a following 
distance warning feature to 
warn the driver to take evasive 
action when there is the possi-
bility of a collision with a vehicle, 
pedestrian or obstacle in front of 
you. If the driver does not take 
evasive action, the brakes are 
applied automatically to help 
reduce vehicle collision dam-
age or, if possible, help prevent 
a collision. (



P.179)

■

Adaptive Cruise Control

This function maintains the set 
vehicle speed and when there is 
a vehicle in front in the same 
traffic lane, it follows the speed 
of the vehicle in front up to the 
maximum of the set vehicle 
speed. (



P.190)

■

Conventional Cruise Con-
trol

In this mode, the system main-
tains a constant vehicle speed. 
It does not follow the vehicle in 
front. This function can be used 
even when the stereo camera 
has temporarily stopped operat-
ing (



P.229). This function is 

used by switching from Adaptive 
Cruise Control to Conventional 
Cruise Control. (



P.207)

NOTICE

●

Keep the windshield (outside 

and inside) clean at all times. 

When the windshield has 

become fogged, or it has a dirt 

or an oil film on it, the stereo 

camera may not detect objects 

accurately and the EyeSight 

system may not operate cor-

rectly. Never mount any device 

to the center air vent, as any air-

flow change may impact Eye-

Sight performance.

●

Do not place any stickers or 

accessories on the windshield 

(outside or inside). If you have 

to do so (for example, legally 

required or electronic toll tag), 

avoid the area directly in front of 

the camera. Otherwise, it may 

adversely affect the field of view 

of the stereo camera and can 

cause improper operation of the 

system. For details, contact a 

Toyota dealer.

●

Do not use any glass coating 

agents or similar substances on 

the windshield. Doing so may 

interfere with the proper opera-

tion of the system.

●

Do not install any film or an 

additional layer of glass on the 

windshield. The system may not 

operate correctly.

Pre-Collision Braking 

System

*

When there is the risk of a 
rear-end collision with an 
obstacle or pedestrian in 
front, the EyeSight system 
helps to prevent or minimize 
a collision by warning the 
driver. If the driver still does 
not take evasive action to 
avoid a collision, the brakes 
can be automatically 
applied just before the colli-
sion in order to reduce 
impact damage, or if possi-
ble, prevent the collision. If 
the driver takes evasive 
action to avoid a collision, 
Pre-Collision Braking Assist 
will operate in order to help 
the driver to prevent or min-
imize the collision.

This function can be acti-
vated when the shift lever is 
in the D, M or N position.

WARNING

●

Never use Pre-Collision Braking 

System and Pre-Collision Brak-

ing Assist to stop your car or 

avoid a collision under ordinary 

conditions. These functions 

cannot prevent collisions under 

all conditions. If the driver relies 

only on Pre-Collision Braking 

System for Brake operation, col-

lisions may occur.

●

When a warning is activated, 

pay attention to the front of the 

vehicle and its surroundings, 

and operate the brake pedal 

and/or take other actions if nec-

essary.

●

The EyeSight Pre-Collision 

Braking System is primarily 

designed to prevent rear-end 

collisions with other vehicles 

when possible or to minimize 

damage and injuries in the 

event of a collision. In addition 

to other vehicles, things such as 

motorbikes, bicycles and pedes-

trians can also be treated as 

obstacles. However, there may 

be cases when detection is not 

possible depending on a variety 
of conditions

*2

. For example, 

when a vehicle is viewed from 

the side, oncoming vehicle, 

vehicles approaching in 

reverse, small animals or chil-

dren, or walls or doors are not 

likely to be detected.

●

Pre-Collision Braking System 

will operate at the point when it 

determines that a collision can-

not be avoided and is designed 

to apply strong braking force 

just before a collision. The result 

of this varies depending on a 
variety of conditions

*2

. Because 

of this, performance of this func-

tion will not always be the same.

●

When Pre-Collision Braking 

System is activated, it will con-

tinue to operate even if the 

accelerator pedal is partially 

depressed. However, it will be 

canceled  if the accelerator 

pedal is suddenly or fully 

depressed.

●

If the driver depresses the brake 

pedal or turns the steering 

wheel, the system may deter-

mine that this constitutes eva-

sive action by the driver, and the 

automatic braking control may 

not activate in order to allow the 

driver full control.

●

When the difference in speed 

with the obstacle in front is the 
following figure

*1

or more, it may 

not be possible to avoid a colli-

sion. Even if the speed differ-
ence is the following figure

*1

 or 

less, in cases such as when 

another vehicle cuts in front of 

you, or in other cases depend-

ing on visibility, the condition of 

road surface and other fac-
tors

*2

, the function may be 

unable to stop the vehicle or 

may not activate. Pre-Collision 

Braking Assist also may not 

activate depending on the con-
ditions

*2

 listed below.

:For vehicles: approximately 30 

mph (50 km/h),
For pedestrians: approxi-
mately 20 mph (35 km/h)

:Conditions in which Pre-Colli-

sion Braking System cannot 
detect obstacles:

• Distance to obstacle in front of 

you, speed difference, proxim-

ity conditions, lateral displace-

ment (the amount of offset)

The EyeSight system can also 
detect pedestrians. The Eye-
Sight system detects pedestri-
ans from their size, shape and 
movement. The system detects 
a pedestrian when the contour 
of the head and shoulders are 
clear.

the system may not be able to 

prevent a collision.

If the driver operates the brake 

pedal during automatic braking, 

the pedal may feel stiff; however, 

this is normal. By depressing the 

brake pedal further you can apply 

more braking force.

Detection of pedestrians

4-5. EyeSight

When there is an obstacle in front of you during driving, the system 
activates in the following sequence in order to warn the driver and to 
activate braking control and the stop lights.

Following distance warning:

When the system determines that there is a risk of collision, an alert sounds 
repeated short beeps and the indicators on the meter display illuminate to 
warn the driver.
The Following Distance Warning operates when Adaptive Cruise Control is 
not activated.
When the driver depresses the brake pedal to decelerate and achieves a 
suitable following distance, the warning is canceled.

First braking and warning:

When the system determines that there is a high risk of collision with an 
obstacle in front, an alert sounds repeated short beeps and the indicators 
on the meter display illuminate to warn the driver. Braking control may be 
activated and in some situations, engine output may also be controlled. If 
the system determines that the amount of evasive action (braking, steering, 
etc.) taken by the driver has reduced the risk of collision, braking activation 
is canceled.

Secondary braking and warning:

WARNING

The EyeSight system’s Pre-Colli-

sion Braking function also identi-

fies pedestrians as obstacles. 

However, depending on the con-

ditions, there may be cases when 

the system cannot detect a 

pedestrian. In the following condi-

tions, the possibility that the sys-

tem may not be able to detect a 

pedestrian as an object is particu-

larly high.

●

Pedestrians are walking in a 

group.

●

A pedestrian is next to a wall or 

other obstacle.

●

A pedestrian is using an 

umbrella.

●

A pedestrian is wearing clothes 

that are a similar color to the 

surrounding environment.

●

A pedestrian is carrying bulky 

luggage.

●

A pedestrian is bent over, 

crouching down or lying down.

●

A pedestrian is in a dark loca-

tion.

●

A pedestrian suddenly crosses 

in front of you from the side or 

suddenly runs in front of you.

If the system then determines that the risk of collision is extremely high, the 
alert changes to a continuous beeping sound and stronger braking control 
is activated. Despite any evasive action taken by the driver, if the system 
subsequently determines that a collision is unavoidable, braking and 
engine output are controlled by the system.
When the vehicle is completely stopped by the automatic braking system, a 
short tone “3 intermittent beeps, 1 short beep and 1 long beep” will sound 
and braking will be gradually released and the vehicle will start creeping. To 
stop the vehicle completely, depress the brake pedal after the vehicle has 
stopped.

●

Neither first braking nor secondary braking will operate in the following 

cases.

• The vehicle speed is approximately 1 mph (1 km/h) or less (When the shift 

lever is in the N position and your vehicle speed is approximately 2 mph (4 

km/h) or less) or 100 mph (160 km/h) or more.

• VSC is active.

●

If the system detects the stop lights of the vehicle in front, your vehicle will 

start decelerating earlier than if it does not.

●

There are some cases where the first braking is applied for a longer period 

of time. One of the reasons for this is due to a large speed difference with 

an obstacle in front. In those cases, stronger or weaker braking control 

may be activated.

After the Pre-Collision Braking System operation, a message 
appears and stays on the meter display for a certain period of time.
