Foreword
Congratulations on choosing a SUBARU vehicle equipped with EyeSightTM.
EyeSight incorporates the latest driver assistance features available from
SUBARU, including such features as Adaptive Cruise Control, a Lead Vehicle Start
Alert and a Lane Departure and Lane Sway Warning, all of which are designed to
assist the driver in making decisions and increase driver comfort and
convenience. Initially, the operation and use of the various EyeSight features may
be unfamiliar to you. That is why we urge you to read this manual carefully before
using EyeSight. We also recommend that you first take the time to test EyeSight in
order to experience its features for yourself so that you can become familiar with
their operation.
Please keep in mind that it is the responsibility of drivers to operate their vehicles
safely at all times. Drivers should always remain alert and should never become
complacent while operating their vehicles because of the presence of EyeSight.
EyeSight is never a substitute for active driver involvement and it may not operate
optimally under all driving conditions.
This booklet is a supplement to the Owner’s Manual for your SUBARU vehicle and
contains a detailed description of EyeSight. It should be read in conjunction with
your Owner’s Manual so that you will gain a thorough understanding of the proper
operation of your vehicle.
The information, specifications and illustrations found in this booklet are those in
effect at the time of printing. FUJI HEAVY INDUSTRIES LTD. reserves the right to
change specifications and designs at any time without prior notice and without
incurring any obligation to make the same or similar changes on vehicles
previously sold.
Please keep this booklet together with your Owner’s Manual and leave it in the
vehicle at the time of resale. The next owner will need the information it contains.

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 52.
xFor Conventional Cruise Control, refer to page 65.
The EyeSight system in your vehicle is designed for use in coun-
tries in which traffic operates on the right-hand side of the road.
EyeSight for LHD vehicles such as yours is not designed for use in
countries in which vehicles are driven on the left-hand side of the
road.
xThe system may not operate correctly under the conditions listed below.
When these conditions occur, turn off the Pre-Collision Braking System.
Also, do not use Adaptive and Conventional Cruise Control.
- The tire pressure is not correct.*1
- The temporary spare tire is installed on any wheel.*1

for your vehicle.

About EyeSight

CAUTION
xThe characteristics of the stereo cameras are similar to those of human
eyes. For this reason, conditions that make it difficult for the driver to see
in the forward direction have the same effect on the stereo cameras and
make it difficult for the system to detect vehicles, obstacles and traffic
lanes.
xDetection by the EyeSight system is limited to objects that are within the
range of the stereo cameras’ field of vision. Also, after an object enters the
range of the cameras’ field of vision, it may take some time for the system
to detect it as a controllable target and warn the driver.
xUnder the conditions listed below, it will become more difficult for the sys-
tem to detect the vehicle in front, motorcycles, bicycles, pedestrians and
obstacles on the road, and lane markers. 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 particu-
lar, 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 old wipers are used.)
- When affected by strong light from the front (sunlight or headlight beams
of oncoming traffic, etc.)
- When the front windshield washer is being used.
- The windshield has become fogged, or snow, dirt, dust or frost has
adhered to it, reducing the stereo cameras’ field of view.
- The vehicle is tilted at an extreme angle due to loaded cargo or other
factors.
- 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 or
other substances to obscure the view
- When the stereo cameras’ field of view is obstructed (for example by a
canoe on the roof of the vehicle)
Low objects surrounding the vehicle cannot
be detected.

completely covered in snow, etc.)
- When the stereo camera lenses are dirty due to fingerprints, etc.
- When accurate detection is not possible due to reflections in the front
windshield
- When the stereo cameras have become misaligned due to a strong
impact
xUnder the conditions listed below, EyeSight may temporarily 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 sunshine, 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
xWhen there is a malfunction in the EyeSight system, turn off the Pre-Colli-
sion Braking System (refer to page 30) and the Lane Departure Warning
(refer to page 60), and stop using the Adaptive Cruise Control. Contact
a SUBARU dealer and have the system inspected.

Handling of the Stereo Cameras
CAUTION
xA function is included that will automatically detect that the fronts of the
stereo cameras are dirty. However it is not 100% effective.
Under certain conditions, this function may fail to detect that the fronts of
the stereo cameras have become dirty. In addition, this function may not
detect that there is snow or ice on the windshield close to the stereo cam-
eras. In such conditions, be sure to keep the windshield clean at all times
(indicated by ). Otherwise the system may not operate correctly.
When this function detects that the fronts of the stereo cameras are dirty,
no EyeSight functions are activated except for Conventional Cruise
Control.
xThe stereo camera is a precision component. Always observe the following
precautions especially when handling lenses.
- Never touch the stereo camera lenses, and do not attempt to wipe or
clean the lenses. Doing so could cause lens damage or contamination
and lead to improper system performance.
If you ever touch a lens for any reason, be sure to contact a SUBARU
dealer.

- When cleaning the front
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 adhesive sur-
face does not come in
contact with the windshield
or the lens. Be sure to
remove the paper after
cleaning.
- When having the inside of windshield cleaned at a service station, etc.,
be sure to request that the attendant covers the camera covers before
washing the vehicle.
- Do not subject the stereo cameras to a strong impact.
- Do not remove or disassemble the stereo cameras.
- Do not change the positions where the stereo cameras are installed or
modify any of the surrounding structures.
xDo not install an interior rearview mirror other than a genuine SUBARU
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 cameras. Failure
to do so may affect the stereo cameras’ field of vision and could prevent
the EyeSight system from functioning properly.

xDo not install any accessories other than the ones designated by SUBARU
on the prohibited areas shown in the illustrations (grey zones).
Even if some accessories are installed on the outside of the prohibited areas,
abnormal operation of EyeSight may occur due to the reflection of the light or
any objects. In this situation, move the accessories. For details, contact a
SUBARU dealer.
<Side view> <Front view>
xDo not place any objects on top of the instrument panel. The stereo cameras
may not be able to detect objects accurately and the EyeSight system may
not function properly due to reflections in the front windshield. For details,
contact a SUBARU dealer.
xIf the top of the instrument panel is polished with chemicals or other sub-
stances, the stereo cameras may not be able to detect objects accurately
and the EyeSight system may not operate properly due to reflections in the
front windshield.
xDo not install any wiper blades other than genuine SUBARU wiper blades.
Doing so may affect the stereo cameras’ field of vision and could prevent the
EyeSight system from functioning properly.
xReplace damaged wiper blades as soon as possible. The stereo cameras
may not be able to detect objects accurately and the EyeSight system may
not function properly due to liquid remaining on the windshield.
xDo not install any accessories
on the front side such as on
the hood or the grille. It may
affect the camera view and
the system may not operate
correctly.
xMake sure that the cargo
loaded on the roof does not
obstruct or interfere in the ste-
reo cameras’ field of view.
Obstructing the stereo cam-
eras’ view may impair the sys-
tem operation. For details,
contact a SUBARU dealer.

EyeSight includes the following functions.
QPre-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 20.
QAdaptive 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.
