Foreword
Congratulations on choosing a SUBARU vehicle equipped with EyeSight
TM
.
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. SUBARU CORPORATION 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.

    How to activate Adaptive Cruise Control on my Subaru Impreza 2023?
    • A
      Ashley GeorgeAug 17, 2025
      First, ensure you've pressed the (CRUISE) switch; the (Adaptive Cruise Control indicator) won't appear if you haven't. Also, check if EyeSight operation is temporarily stopped, indicated by the (EyeSight temporary stop indicator: White) on the combination meter display. Correct any issues causing the temporary stop before setting Adaptive Cruise Control again. Finally, confirm that the (READY indicator) is displayed, as Adaptive Cruise Control cannot be activated without it.

    Debra EvansAug 20, 2025
    Why does braking control activate frequently with Adaptive Cruise Control in heavy traffic in my Subaru Impreza 2023?
    • K
      kelly40Aug 20, 2025
      When Adaptive Cruise Control is active, the EyeSight system adjusts to vehicles or objects in front, leading to frequent acceleration and deceleration. If maintaining a consistent following distance is difficult in heavy traffic, poor weather, or urban environments, consider not using Adaptive Cruise Control.

    What to do if EyeSight does not restart after a temporary stop in my Subaru Automobile?
    • C
      carolpachecoAug 23, 2025
      EyeSight may not restart after a temporary stop due to several reasons. If you are driving in the rain with poorly performing wipers or there is a smear on the windshield, replace the wipers or clean the windshield. Also, EyeSight may temporarily stop operating in poor weather conditions with heavy rain, snow, fog, or dust. Furthermore, direct sunlight or bright headlights at nighttime can cause a temporary stop. Parking in extremely hot or cold conditions may also cause EyeSight to temporarily stop until the temperature is suitable for the camera.
  • G

    Why is Adaptive Cruise Control activated even without a vehicle in front in my Subaru Impreza 2023 Automobile?
    • T
      Tara Ortega MDAug 26, 2025
      Adaptive Cruise Control might activate if a vehicle in a neighboring lane is detected or if you're driving on or near a curve. Braking control may activate in response to guardrails, the angle of the steering wheel, or roadside structures.
  • E
    Emily BarnesAug 28, 2025
    Why is acceleration slower or faster when the vehicle in front turns or distance increases in my Subaru Impreza 2023?
    • C
      Cheryl RayAug 28, 2025
      EyeSight's reaction time may be slower when the vehicle in front turns off the roadway or the distance increases, causing a delayed acceleration and longer braking time. Also, acceleration may vary depending on the cruise control mode you selected.
  • S

    Why does the timing of the “Obstacle Detected” warning vary in my Subaru Automobile?
    • P
      Patrick SmithSep 2, 2025
      The “Obstacle Detected” warning sounds when the system determines that more braking is necessary, based on the distance from the vehicle in front and the difference in speed compared to it. As a result, timing may vary depending on how the brakes are applied in relation to the vehicle in front, and your relative speed to that vehicle.
  • Y
    Yolanda FloresSep 5, 2025
    Why does the Lead Vehicle Start Alert activate when there is no vehicle in front of my Subaru Impreza 2023 Automobile?
    • D
      Devin WilsonSep 5, 2025
      The Lead Vehicle Start Alert may issue a warning in response to objects other than a vehicle that appears in front of your vehicle, depending on surrounding objects, traffic environment and weather.
  • V
    Vicki PenaSep 8, 2025
    Why is cruise control canceled automatically in my Subaru Impreza 2023?
    • B
      Benjamin KennedySep 8, 2025
      Cruise control might be canceled automatically if you perform one of the following operations or if the EyeSight system temporarily stops while Adaptive Cruise Control is in use.
  • J
    Julie SanchezSep 12, 2025
    What is the noise when automatic braking control activates in my Subaru Impreza 2023?
    • E
      Erica JohnsonSep 12, 2025
      The noise you hear is the sound of the automatic braking control operating. The system has mechanical components that may make audible sounds during automatic braking control. This does not indicate a malfunction.
  • D
    Danielle ParkerSep 13, 2025
    Why doesn't Lane Keep Assist operate even with lane markers in my Subaru Impreza 2023 Automobile?
    • L
      lroachSep 13, 2025
      Lane Keep Assist requires the road width to be between approximately 10 ft (3 m) and 15 ft (4.5 m) to operate. If the road is too narrow or too wide, the system will not function.
