EyeSight Functions
Pre-Collision Braking System
This function can recognize an impending collision with an obstacle, such as a motorcycle
or pedestrian, or with a vehicle traveling in the same lane ahead of the EyeSight vehicle. It
informs the driver with audible and visual alerts. If the driver takes no corrective action, the
system will automatically apply the brakes to help avoid the collision or minimize impact when
a collision is inevitable.
Pre-Collision Brake Assist
If EyeSight recognizes an impending collision with an obstacle or a vehicle traveling in the
same lane ahead of the EyeSight vehicle, and the driver does not apply enough brake pedal
force, Pre-Collision Brake Assist automatically applies up to full braking pressure in order to
try to reduce stopping distance.
Pre-Collision Throttle Management
This function is designed to help prevent drivers from unintentionally accelerating into a
stopped vehicle or other obstacle in front of the EyeSight vehicle. It simultaneously warns the
driver and reduces engine power until the driver applies the brakes to help avoid an impact.
Pre-Collision Throttle Management is helpful when:
• The driver inadvertently selects Drive instead of Reverse and starts to accelerate toward a
parked car, wall or parking structure.
• Starting to merge onto another road when the vehicle ahead accelerates, but suddenly stops.
Lane Departure Warning
Lane Departure Warning works at speeds of approximately 30 mph or greater to alert the
driver when the vehicle unintentionally moves out of its travel lane and the turn signal is not
used. It takes no corrective vehicle action other than issuing visual and audible warnings.
Lane Sway Warning
Lane Sway Warning works at speeds of approximately 38 mph or greater. It detects repetitive
or unusual side-to-side vehicle movement within the driver’s lane of travel that is usually
indicative of a drowsy driver.
Lane Keep Assist with Lane Departure Prevention
By detecting lane markings in the lane of travel, the system assists the steering operation to
help keep the vehicle within its lane. If the vehicle is about to deviate from a driving lane and
starts crossing the road lines, steering assistance control is triggered in the opposite direction,
helping to avoid lane deviation. A departure warning sound and display in the instrument
cluster alert the driver. These features are designed to function at speeds of approximately
40 mph or greater. Therefore, it is best used on freeways, expressways or interstate highways.
Note: This is a driver selectable feature and must be turned on to be functional.
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. It is designed to help assist drivers, not replace them.

Adaptive Cruise Control and Conventional Cruise Control
This function combines the benefits of Cruise Control with active monitoring of the road
ahead by EyeSight. The system works at speeds above approximately 20 mph and issues
warnings and activates automatic braking when needed.
When selected by the driver, Adaptive Cruise Control can regulate the driver set speed in
order to keep the driver-selected gap between the EyeSight vehicle and the vehicle ahead
traveling in the same lane. It does not replace Conventional Cruise Control, which can still be
used, when desired, without the adaptive function.
Conventional Cruise Control maintains a constant driver set speed. It does not mirror the
speed of a vehicle traveling in the same lane ahead of the EyeSight vehicle. See the Owner’s
Manual for additional information.
Lead Vehicle Start Alert
Lead Vehicle Start Alert notifies the driver when the vehicle in front has started moving but
the EyeSight driver’s vehicle has not. This occurs when the lead vehicle has moved forward a
minimum of 10 feet.
EyeSight Operation
EyeSight uses stereo color cameras to process 3-D images and to identify objects such as
the vehicle in front, obstacles, traffic lanes and other items. Under specific circumstances, if
the driver takes no corrective action, EyeSight will apply the brakes or decrease the throttle to
help avoid a collision or help reduce the severity of a collision.

EyeSight Limitations*
• The EyeSight system needs time to recognize an object or potential obstacle. When the
vehicle speed differential with an obstacle in front is greater than approximately 30 mph,
it may not be possible to avoid an impending collision.
• Sun glare, inclement weather such as heavy rain, blinding snow or fog, or a dirty windshield
will hinder EyeSight operation. A cracked windshield, oil film on the glass or reflections may
impede EyeSight performance. In these conditions, EyeSight may not operate properly or
EyeSight may temporarily stop operating. If you cannot see, EyeSight cannot see.
• EyeSight may not recognize low-contrast objects, those with regularly spaced patterns,
no pattern, horizontal lines, backlit objects, very small objects (less than 3 feet tall) or
non-standard shaped vehicles, such as cement mixers or car-carrier trucks.
• Cargo loaded on the vehicle roof must be positioned so as to not interfere with or obstruct
the camera’s view.
• Non-approved aftermarket vehicle accessories, such as hood protectors, and water-
repellent glass coatings should not be used with EyeSight-equipped vehicles. EyeSight
may not operate properly or EyeSight may temporarily stop operating.
*Please refer to the disclaimer information on the back cover.
Stereo Color Cameras Precautions
The stereo color camera lenses are precision components. When the system detects that the
stereo color camera lenses are dirty, no EyeSight functions will be activated.
Always observe the following precautions:
• Do not touch or try to clean the EyeSight camera lenses inside the vehicle. Extra precaution
should be used when cleaning the inside of the windshield. Over-spray from cleaners
may impair or even damage the cameras’ lenses. Such damage is not covered under any
vehicle warranty.
• Do not attempt to remove or disassemble the stereo color cameras.
• Do not attempt to change the position where the stereo color cameras are installed or
modify any of the surrounding structures.
• Do not install any interior rearview mirror (such as a wide-type mirror) other than a genuine
SUBARU rearview mirror. Also, adjust the rearview mirror so it does not obstruct the stereo
color cameras. Failure to do so may affect the stereo color cameras’ field of vision and
could prevent the EyeSight system from functioning properly.
For more detailed information, please consult your EyeSight Owner’s Manual.

Windshield Glass and Dashboard
There must be no oil film, dirt, scratch or fogging that obstructs the forward visibility of the
stereo color cameras.
Do not stick or attach aftermarket parts on the prohibited areas shown in gray on the
windshield and top of the dashboard in the image in this section.
Even outside the prohibited area, if abnormal operation occurs due to the reflection of the
light or the reflection on the glass, change the adhering position or installation position.
• Application of stickers or antennas, installation of wide‐angle type mirror
– This will affect the visibility of the stereo color cameras and may impair functionality.
• Placement of an aftermarket navigation unit, cellphone or similar on the dashboard
– These things may be reflected on the windshield glass, affecting the recognition of the
stereo color cameras, thus causing its function to not operate as designed.

Other Driver Assist Technologies
Rear Cross Traffic Alert (RCTA)
(if equipped)
Rear Cross Traffic Alert (RCTA) notifies the driver of a collision danger if a vehicle is detected
approaching from either direction, perpendicular to the reversing vehicle. The system uses
radar detection sensors located in the left rear and right rear of the vehicle. The system uses
an audible and visual warning to alert the driver.
Lane Change Assist (LCA)
(if equipped)
Lane Change Assist (LCA) notifies the driver of an approaching vehicle in an adjacent lane or
lanes. The system uses radar detection sensors located in the left rear and right rear of the
vehicle. The sensors illuminate a vehicle icon in the exterior mirror on the side in which the
oncoming vehicle is detected. When the driver uses the turn signal indicator to switch lanes,
and a vehicle is in their path, the radar detection sensor flashes the vehicle icon only in the
exterior mirror on the side the oncoming vehicle is detected.
Blind Spot Detection (BSD)
(if equipped)
Blind Spot Detection (BSD) assists the driver by detecting vehicles located on either side of
the vehicle that are hidden from the driver’s view in the exterior mirror. The system uses radar
detection sensors located in the left rear and right rear of the vehicle. The sensors illuminate a
vehicle icon only in the exterior mirror on the side the oncoming vehicle is detected. When the
driver uses the turn signal indicator to switch lanes, and a vehicle is in their path, the radar
detection sensor flashes the vehicle icon only in the exterior mirror on the side the oncoming
vehicle is detected.
Front View Monitor
(if equipped)
The front view monitor displays an image of the front and front side views of the vehicle
on the multi-function display. The system has a camera located in the grille. This system
helps eliminate blind spots in front of the vehicle and allows the driver to check the forward
direction of travel.

11
Reverse Automatic Braking (RAB) System
(if equipped)
The Reverse Automatic Braking (RAB) system is designed to assist the driver by detecting
objects, to help avoid a possible collision, when the vehicle is moving in a low speed reverse
direction. The system will provide automatic vehicle braking, if a obstacle is detected within
its range.
This system is not a substitute for safe and attentive driving. System effectiveness depends
on many factors, such as vehicle maintenance, weather, and road conditions. Excessive
build-up of dirt, snow or ice will affect the operation of the RAB system. Always exercise
caution and use vehicle mirrors and the Rear-Vision Camera when backing up. See the
Owner’s Manual for complete details on system operation and limitations.
High Beam Assist (HBA)
(if equipped)
High Beam Assist automatically switches the headlights between the high and low beams
when the headlight switch is in the high beam position. The system works in conjunction with
the EyeSight system. The EyeSight system detects a vehicle ahead, or oncoming vehicles,
and switches the headlights automatically from high beam to low beam. See the Owner’s
Manual for complete details on system operation and limitations.
Steering Responsive Headlights (SRH)
(if equipped)
The Steering Responsive Headlights (SRH) system aims the headlight beams in the direction
of vehicle travel on curved roads to help improve visibility at night. See the Owner’s Manual
for complete details on system operation and limitations.
