About EyeSight
10
EyeSight includes the following seven functions.
■Adaptive Cruise Control
This function maintains the set vehicle speed and when there is a vehicle in front in the
same traffic lane, it tracks the speed of the vehicle in front up to the maximum of the set
vehicle speed.
* Refer to page 21.
■Pre-Collision Braking System
This function uses a following distance warning feature to warn the driver to take evasive
action when there is the possibility of a collision with a vehicle or obstacle in front of the
driver’s vehicle. If the driver still does not take evasive action, the brakes are quickly applied
automatically just before the collision in order to reduce the collision damage or, if possible,
prevent the collision.
* Refer to page 43.
■Pre-Collision Throttle Management
This function reduces accidental forward movement caused by the selector lever being
placed in the wrong position or the accelerator pedal being accidently depressed, or
depressed too strongly.
* Refer to page 52.
■Lane Departure Warning
This function warns the driver when the vehicle is about to depart the traffic lane during driv-
ing.
* Refer to page 58.
■Lane Sway Warning
This system detects vehicle drifting caused by driver fatigue, failure to concentrate on the
road, inattention, strong crosswinds or other factors, and warns the driver.
* Refer to page 61.
■Lead Vehicle Start Alert
This function notifies the driver when the vehicle in front has started moving but the driver’s
vehicle has not.
* Refer to page 64.
EyeSight Functions

Adaptive Cruise Control

 ŸContinued from previous page
- Traffic conditions when frequent acceleration and deceleration make it diffi-
cult to maintain the following distance
It may not be possible for the system to perform as the traffic conditions
require.
- Steep downhill grades
The set vehicle speed may be exceeded.
- On a steep continuous downhill grade
The brakes may overheat.
- Roads and overpasses with repeated steep uphill and downhill grades
Detection of the vehicle in front may be lost, or the road surface may be
detected instead of the vehicle in front, making correct control impossible.
- When entering an interchange, service area, parking area, junction, toll
booth or other facility
Detection of the vehicle in front may not be possible.
- When there are sudden changes in brightness, such as at a tunnel entrance
or exit
- When visibility is poor due to sand, smoke or water vapor blowing in the
wind, or when the vehicle in front or oncoming traffic causes water, snow,
dirt or dust to obscure the view
Detection of the vehicle in front may be lost, or water or other substances
may be incorrectly detected instead of the vehicle, making correct control
impossible.
- When there is snow, frost, dirt or dust on the windshield or it is clouded
- When water droplets from rain or the window washer, or dirt has not been
fully wiped off the windshield
It may not be possible to detect the vehicle in front, making correct control
impossible.
- When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)

- When the vehicle in front is
not directly ahead of your
vehicle and is shifted to
one side
- When there is an obstacle
at the side of the road
- When the speed difference with the vehicle (or object) in front is more
than 20 MPH (30 km/h)
- When a vehicle cuts into your lane in front of you
- When the distance between vehicles is extremely small
- When your vehicle is drifting within the lane
- When driving on a bumpy or unpaved road surface
- When driving on a road with extremely narrow lanes, such as when traf-
fic restrictions are in effect or in areas where construction work is taking
place
- When normal driving has become compromised due to an accident or
malfunction
- When extremely heavy cargo is loaded in the cargo area, rear seat or
trunk of your vehicle
xThere are limits to the capabilities of Adaptive Cruise Control. Even when
the vehicle in front is detected, the system may not be able to decelerate in
time in cases such as when the difference in speeds is large or when the
vehicle in front decelerates suddenly. Operate the brake pedal and decel-
erate as necessary.
xBefore using the system, perform a daily inspection and verify that there
are no malfunctions of the tires or brakes.
*Refer to the separate “Warranty and Maintenance Booklet”.
xIf the buzzer sounds frequently, do not use Adaptive Cruise Control.

xEven when the following distance is short, the “brake more” warning may
not activate in the following cases.
- When the speed difference compared to the vehicle in front is small (the
two vehicles are travelling at almost the same speed)
- When the vehicle in front is traveling faster than your vehicle (the follow-
ing distance is gradually increasing)
- When another vehicle cuts into your lane very close to your vehicle
- When the vehicle in front decelerated suddenly
- When there are repeated uphill and downhill grades
CAUTION
xAfter Adaptive Cruise Control has started, it maintains control continuously
according to the behavior of the vehicle in front. When your vehicle comes
to a stop because the vehicle in front has stopped, the automatic braking
function will be cancelled immediately after stopping and the vehicle will
start creeping forward gradually (at the same time three short beeps and a
single long beep will sound). Be sure to depress the brake pedal and stop
the vehicle completely.
Note that the vehicle is not maintained at a standstill position and will not
automatically start moving from a standstill position.
xBraking may not be sufficient depending on the following conditions. Oper-
ate the brake pedal and decelerate as necessary.
- Vehicle conditions (amount of load, number of occupants, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- Vehicle maintenance status (brake systems, tire wear, air pressure, tem-
porary spare tire is being used, etc.)
- When the brakes are cold. (For example, just after the engine is started
or when the outside temperature is low.)
- For a short period of time when driving after the engine is started until the
engine has warmed-up
- When the brakes are overheated on downhill grades (braking effective-
ness may be reduced)
- When driving in rain or after washing the vehicle (the brakes may
become wet and braking effectiveness may be reduced)
- When the speed to potential obstacles is more than 20 MPH (30 km/h)

Adaptive Cruise Control

xWhen a vehicle in front is detected
The vehicle tracks the lead vehicle in front,
and will maintain the chosen following dis-
tance, up to the set target vehicle speed -
between 25 MPH (40 km/h) and 90 MPH
(145 km/h).
xIf the lead vehicle is no longer tracked
within a distance of approximately 100 ft
(30 m) and a speed of approximately 20
MPH (30 km/h) or less is detected, a buzzer
sounds single long beep and Adaptive
Cruise Control function is canceled.
At this time, the lead vehicle indicator
flashes.
If the vehicle in front is no longer detected
under conditions other than the previous
ones, the vehicle gradually accelerates back
to the set target vehicle speed and will drive at
that constant speed.
If a vehicle in front is detected while accelerat-
ing to the set target vehicle speed, vehicle
tracking will be started again.
NOTE
xWhen the brakes are applied by Adaptive Cruise Control, the vehicle’s
brake lights will illuminate.
xEven if there is no lead vehicle present, on a downhill grade, the Adaptive
Cruise Control’s automatic brake may operate in order to maintain the set
target vehicle speed.
xTo temporarily accelerate quickly, use the accelerator pedal.

Pre-Collision Braking System

Pre-Collision Braking System
When there is the risk of a rear-end collision with a obstacle in front, the EyeSight system
helps to minimize or prevent 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
collision in order to reduce impact damage, or if possible, prevent the collision. When the
system determines that there is a high risk of collision with an obstacle ahead, and the
driver depresses the brake pedal, the system activates braking assist. (Pre-Collision Brake
Assist)
This system can be effective not only with frontal collisions, but also with offset (right or left)
collisions. This function can be activated when the select lever is in the , or posi-
tions.
Continued on next page Ÿ
WARNING
xNever use the Pre-Collision Braking System and Pre-Collision Brake
Assist to stop your car under ordinary conditions. The Pre-Collision
Braking System cannot prevent collisions under all conditions. If the driver
relies only on the Pre-Collision Braking System for Brake operation, colli-
sions may occur.
xWhen 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.
xThe EyeSight Pre-Collision Braking System function is primarily designed
to prevent rear-end collisions with other vehicles when possible and to
minimize damage and injuries in the event of a collision. In addition to
other vehicles, things such as motorbikes, bicycles and pedestrians can
also be treated as obstacles. However, there may be cases when detec-
tion is not possible depending on a variety of conditions*. It is highly proba-
ble that the Pre-Collision Braking System function does not work against
vehicles parked in a lateral position, oncoming vehicles, backing up vehi-
cles, small animals, infants, fences, walls, gates, etc.
xThe Pre-Collision Braking System function will operate at the point when it
determines that a collision cannot 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*. Because of this, performance of this
function will not always be the same.
xWhen the Pre-Collision Braking System function is activated, it will con-
tinue to operate even if the accelerator pedal is partially depressed. How-
ever, it will be canceled if the accelerator pedal is fully depressed.
xIf the driver depresses the brake pedal or turns the steering wheel, the sys-
tem may determine that this constitutes evasive action by the driver, and
the automatic braking control may not activate in order to allow the driver
full control.
xWhen the difference in speed with the obstacle in front is approximately 20
MPH (30 km/h) or more, it may not be possible to avoid a collision. Even if
the speed difference is approximately 20 MPH (30 km/h) or less, in cases
such as when another vehicle cuts in front of you, or in other cases
depending on visibility, condition of road surface and other factors*, the
function may be unable to stop the vehicle or may not activate. Pre-Colli-
sion Brake Assist may also not activate depending on the conditions* listed
below.
*Conditions
- Distance to obstacle in front of you, speed difference, proximity condi-
tions, lateral displacement (the amount of offset)
- Vehicle conditions (amount of load, number of occupants, condition of
tires, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- When visibility ahead is poor (rain, snow, fog or smoke, etc.)
- When the detected object is one of the following
• A domestic animal or other animal (a dog or deer, etc.)
• A guardrail, telephone pole, tree, fence or wall, etc.

- Even if the obstacle is a motorcycle, bicycle or pedestrian, depending on
the brightness of the surroundings as well as the relative movement, and
aspect or angle of the object, there may be cases when the system can-
not detect it.
- When the system determines that operation by the driver (based on
accelerator pedal operation, braking, steering wheel angle, etc.) is
intended as evasive action
- Vehicle maintenance status (brake systems, tire wear, tire pressure,
whether a temporary spare tire is being used, etc.)
- When towing a trailer or vehicle, etc.
- When the brakes are cold due to outside temperature being low or just
after starting the engine.
- When the brakes are overheated on downhill grades (braking effective-
ness is reduced)
- When driving in rain or after washing the vehicle (the brakes are wet and
braking effectiveness is reduced)
- Recognition conditions of the stereo cameras
In particular, the function may be unable to stop the vehicle or may not
activate in the following cases.
• Bad weather (for example heavy rain, a blizzard or thick fog)
• When visibility is poor due to sand, smoke or water vapor in the air or
when the vehicle in front or oncoming traffic causes water, snow, dirt,
dust or other substances to obscure the view through the windshield
• When driving at night or in a tunnel without the headlights on
• When driving at night or in a tunnel when there is a vehicle in front that
does not have its taillights on
• When approaching a motorcycle, bicycle or pedestrian at night
• When ambient light is poor in the evening or early morning
• When a vehicle, motorcycle, bicycle or pedestrian is outside the area
illuminated by the headlights
• When affected by strong light from the front (for example, sunlight at
dawn, sunset or headlight high beams, etc.)
• When there is snow, frost, dirt or dust on the windshield or it is clouded
• When fluid has not been fully wiped off the windshield during or after
washer use
• When the target cannot be correctly recognized because the stereo
cameras’ view is obstructed by water droplets from rain or the window
washer, or by the wiper blades.
• When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)
• When the rear aspect of
the vehicle in front is
low, small or irregular
(the system may recog-
nize another part of the
vehicle as its rear and
will determine operation
from that)
- When there is an
empty truck or trailer
with no rear and/or
side panels on the
cargo bed
- With vehicles that
have cargo protruding
from their back ends
- With non-standard
shaped vehicles (vehicle transporters or vehicles with a sidecar
fitted, etc.)
- When the height of the vehicle is low, etc.

Conventional Cruise Control
Conventional Cruise Control is a driving support system intended to allow more comfortable
driving on expressways, freeways and interstate highways. It can be used to travel at a con-
stant speed by maintaining the vehicle speed that was set by the driver (approximately 25
MPH (40 km/h) to 90 MPH (145 km/h)). Please remember that you should not exceed
posted speed limits.
About Conventional Cruise Control
WARNING
xWhen Conventional Cruise Control is functioning, the system does not per-
form tracking control to maintain following distance, as when using Adap-
tive Cruise Control.
Strive for safe driving and operate the brake pedal to decelerate the vehi-
cle as necessary in order to ensure a safe following distance from the vehi-
cle in front.
xUnder the following conditions, do not use the Conventional Cruise
Control. Doing so may result in an accident.
- Roads with heavy traffic or roads with sharp curves
You may fail to drive at a speed that is appropriate for the road condi-
tions, possibly resulting in an accident.
- Frozen roads, snow-covered roads or slippery road surfaces
The tires may spin, causing loss of control of the vehicle.
- Steep downhill grades
The set vehicle speed may be exceeded.
- On a steep continuous downhill grade
The brakes may overheat.
- When towing a trailer.
CAUTION
When using Cruise Control, be sure to check the display screen to confirm
which Cruise Control mode is selected: Adaptive Cruise Control or
Conventional Cruise Control.
