About EyeSight
EyeSight is a driving support system that uses a range of functions to assist the driver in
making decisions in order to provide for more safe and comfortable driving and to reduce
driver fatigue. Making use of images created by stereo cameras specially designed by
SUBARU, EyeSight detects the vehicle in front, obstacles, traffic lanes and other items.
EyeSight
WARNING
Drivers are responsible for driving safely. Always comply with all
traffic rules and regulations regardless of the fact that your vehicle
is equipped with EyeSight. Always maintain a safe following dis-
tance behind the vehicle in front of you, pay attention to your sur-
roundings and the driving conditions, operate the brake pedal and
take other action as necessary in order to maintain a safe following
distance.
Never attempt to drive relying on EyeSight alone.
EyeSight is intended to assist the driver in making decisions in
order to reduce the chance of accidents or damage and lessen the
burden on the driver.
When a warning is activated, pay attention to what is in front of you
and to your surroundings, operate the brake pedal and take other
action as necessary.
This system is not designed to support driving in poor visibility or
in extreme weather conditions, or to protect against careless driv-
ing when the driver is not paying complete attention to the road
ahead. It also cannot prevent collisions from occurring in all driving
conditions.
There are limits to the EyeSight recognition performance and con-
trol performance. Be sure to read the instructions for each function
before using the system, and always use it properly. Improper use
may lead to failure of control performance, which could cause an
accident.
Refer to the following pages for each function:
xFor the Pre-Collision Braking System, refer to page 20.
xFor Adaptive Cruise Control, refer to page 32.
xFor Pre-Collision Throttle Management, refer to page 62.
xFor Conventional Cruise Control, refer to page 75.

EyeSight includes the following functions.
■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.
Ÿ Refer to page 20.
■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.
Ÿ Refer to page 32.
■Lane Keep Assist
This function supports control of drifting out of a lane by detecting lane markings (e.g., white
lines) on highways, etc. and assisting steering operation.
Ÿ Refer to page 54.
■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.
Ÿ Refer to page 62.
■Lane Departure Warning
This function warns the driver when the vehicle is about to depart the traffic lane during driv-
ing.
Ÿ Refer to page 68.
■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.
Ÿ Refer to page 71.

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. If the driver
takes evasive action to avoid a collision, Pre-Collision Brake Assist will operate in order to
help the driver to prevent the collision.
This system can be effective not only with direct rear-end collisions, but also with offset
rear-end collisions. This function can be activated when the select lever is in the , or
positions.
WARNING
xNever use the Pre-Collision Braking System and Pre-Collision Brake 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 the
Pre-Collision Braking System for Brake operation, collisions 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 is primarily designed to pre-
vent rear-end collisions with other vehicles when possible and to minimize
damage and injuries in the event of a collision. In addition to other vehi-
cles, things such as motorbikes, bicycles and pedestrians 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 vehi-
cle is viewed from the side, oncoming vehicle, vehicles approaching in
reverse, small animals or children, or walls or doors are not likely to be
detected.
xThe Pre-Collision Braking System will operate at the point when it deter-
mines 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
*2. Because of this, performance of this function will
not always be the same.
xWhen the Pre-Collision Braking System is activated, it will continue to
operate even if the accelerator pedal is partially depressed. However, it will
be canceled if the accelerator pedal is deeply depressed.
xIf the driver depresses the brake pedal or turns the steering wheel, the system
may determine that this constitutes evasive action by the driver, and the auto-
matic braking control may not activate in order to allow the driver full control.
xWhen the difference in speed with the obstacle in front is the following fig-
ure
*1 or more, it may not be possible to avoid a collision. Even if the speed
difference is the following figure*1 or less, in cases such as when another
vehicle cuts in front of you, or in other cases depending on visibility, the
condition of road surface and other factors
*2, the function may be unable to
stop the vehicle or may not activate. Pre-Collision Brake Assist also may
not activate depending on the conditions
*2 listed below.
*1:For vehicles: approximately 30 MPH (50 km/h),
For pedestrians: approximately 21 MPH (35 km/h)
*2: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, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- When visibility ahead is poor (rain, snow, fog or smoke, etc.)
- When the detected object is something other than a vehicle, motorcycle,
bicycle or pedestrian
xA domestic animal or other animal (a dog or deer, etc.)
xA 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 another 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.
xBad weather (for example heavy rain, a blizzard or thick fog)
xWhen 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
xWhen driving at night or in a tunnel without the headlights on
xWhen driving at night or in a tunnel when there is a vehicle in front that
does not have its taillights on
xWhen approaching a motorcycle, bicycle or pedestrian at night
xWhen ambient light is poor in the evening or early morning
xWhen a vehicle, motorcycle, bicycle or pedestrian is outside the area
illuminated by the headlights
xWhen affected by strong light from the front (for example, sunlight at
dawn, sunset or headlight beams, etc.)
xWhen there is snow, frost, dirt or dust on the windshield or it is clouded
xWhen fluid has not been fully wiped off the windshield during or after
washer use
xWhen 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.
