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 u se 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 responsibilit y 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 acti ve driver involvement and it may not operate
optimally under all driving conditions.

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:
x For the Pre-Collision Braking System, refer to page 20.
x For Adaptive Cruise Control, refer to page 32.
x For Pre-Collision Throttle Management, refer to page 62.
x For Conventional Cruise Control, refer to page 75.

Handling of the Stereo Cameras
CAUTION
xA function is included that will automatic ally 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.
x The 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 damage or soil the lens, and lead to
improper system performance.
If you ever touch a lens for any reason, be sure to contact a SUBARU
dealer.

Pre-Collision Braking System
27
When there is an obstacle in the forward direction during driving, the system activates in the
following sequence in order to warn the driver, activate braking control, and active the brake
lights.
Following Distance Warning:
When the system determines that there is a risk of collision, a buzzer sounds repeated short
beeps and the indicators on the multi information display illuminate to warn the driver.
The Following Distance Warning operates when Adaptive Cruise Control is not set.
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, a
buzzer sounds repeated short beeps and the indicators on the multi information display illu-
minate to warn the driver, and braking control is activated and the engine output, in some
situations, is also 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 activa-
tion is canceled.
Secondary Braking and Warning:
If the system then determines that the risk of collision is extremely high, the buzzer changes
to a continuous beeping sound and stronger braking control is activated. If, despite any eva-
sive action taken by the driver, the system subsequently determines that a collision is
unavoidable, braking control and the engine output control are continued.
Even after the vehicle has stopped, depress the brake pedal.

Until the brake pedal is depressed, a mes-
sage appears and stays in the warning screen
area of the multi information display for
approximately 2 minutes. A single continuous
beep sounds while the message is displayed.

Adaptive Cruise Control
Adaptive Cruise Control is a driving support system intended to allow more comfortable driving on
expressways, freeways and interstate highways. The vehicle in front in the same traffic lane is
detected by means of the stereo cameras, and your vehicle tracks the vehicle in front (up to the
maximum speed of the set vehicle speed) while automatically maintaining a following distance that
corresponds to the speed of the vehicle in front. Through operation of the electronic parking brake,
the system uses the vehicle’s conventional braking system to stop your vehicle when the vehicle
in front is stopped. The vehicle is capable of being controlled at a speed between approximately 0
and 90 MPH (145 km/h). Please remember that you should not exceed posted speed limits.
WARNING
xThis system does not provide the driver with an automatic driving function
that handles all traffic conditions.
x Do not rely excessively on Adaptive Cruise Control. This system is not intended
to assist in driving when the driver is not paying full attention to what is ahead of
him/her due to distractions or a lack of concentration while driving, or under
conditions of poor visibility. It is not intended to prevent rear-end collisions.
Strive for safe driving at all times. Always maintain a safe following distance
behind the vehicle in front of you, pay attention to your surroundings and the
driving conditions, and operate the brake pedal and take other action as neces-
sary.
x Set the set vehicle speed within a range that is appropriate to the road con-
ditions and surrounding environment.
x Before using the system, perform a daily inspection and verify that there
are no malfunctions of the tires or brakes.
Ÿ Refer to the separate “Warranty and Maintenance Booklet”.
x The system may not operate correctly under the conditions listed below.
When these conditions occur, do not use Adaptive Cruise Control.

Troubleshooting
94
A vehicle (in front of your vehicle) is not detected, is detected later or detection is
lost quickly.
Is the vehicle in front stopped, moving slowly relative to your vehicle or moving
extremely slowly?
Detection of stopped vehicles, vehicle moving slowly relative to your vehicle, and
vehicles moving extremely slowly may be difficult.
Is the windshield dirty or fogged?
If the windshield is dirty or fogged, it may not be possible to detect object or vehi-
cles. Clean off the dirt or fog from the windshield, and then try using the system
again.
Is the vehicle in front far away?
The maximum detection distance of EyeSight’s stereo cameras is approximately
360 ft (110 m). Detection is not possible if the vehicle is farther away.
Is the vehicle on a curve?
The detection range is limited in the left and right directions when the cameras are
properly aimed.
Is the vehicle on a road with repeated uphill and downhill grades (such as an over-
pass), or on a banked road?
The detection range is limited in the up and down directions.
Did the vehicle detected in front change?
Detection may be delayed after the vehicle in front has changed.
Have water, snow or other substances been kicked up by the vehicle in front as it
drives?
When water or snow have been kicked up, it may not be possible to detect the
vehicle in front.
Control is activated even though no vehicle in front is detected?
Is there a vehicle in the neighboring lane?
Depending on the road conditions, vehicles in neighboring lanes may be detected
as well as a vehicle directly in front.
Are you driving on or near a curve?
When driving on a curve, braking control may be activated in response to guard
rails, the angle of the steering wheel, or roadside structures.
The Lead Vehicle Start Alert activates, even though there is no vehicle in front.
Depending on surrounding objects, traffic environment and weather, the Lead
Vehicle Start Alert may issue a warning in response to objects other than a vehicle
that appear in front of your vehicle.
