assist the driver in making decisions and increase driver comfort and
convenience. Initially, the operation and u se of the various EyeSight features may

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.

About EyeSight

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 helps suppress lane drifting by detecting lane markings (e.g., white lines) on
highways, etc. and by a ssisting steering operation.
Ÿ Refer to page 54.
■Pre-Collision Throttle Management
This function reduces accidental forward movement caused by the select 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.
