How To Disable Subaru EyeSight: A Comprehensive Technical Guide
Subaru EyeSight is a complex driver assistance system that integrates stereo cameras, adaptive cruise control, and pre-collision braking; disabling it requires specific button combinations or physical interventions depending on the vehicle generation. While the system can be temporarily toggled via steering wheel controls for specific drive cycles, permanent deactivation is not natively supported by the vehicle software due to federal safety compliance standards.
Pre-Operational Requirements and System Familiarization
Before attempting to modify the operation of your Subaru EyeSight system, you must understand the distinction between temporary suppression and permanent system faults. Subaru designs EyeSight as a safety-critical suite; therefore, most modifications are designed to be transient.
- Essential Equipment: Access to the steering wheel-mounted control interface, specifically the "i/SET" switch and the steering wheel menu toggles.
- Mandatory Knowledge: Familiarity with the instrument cluster multi-function display (MFD) navigation, as most adjustments are menu-driven rather than mechanical.
- Environmental Prerequisites: Ensure the vehicle is in Park (P) or a stationary state with the ignition in the "On" position to ensure all menu options are accessible.
- Safety Warning: Disabling EyeSight functions removes protective layers such as Automatic Emergency Braking (AEB) and Lane Keep Assist. Operate the vehicle with extreme caution when these systems are inactive.
Procedural Workflow for System Suppression
Step 1: Accessing the EyeSight Menu via the Multi-Function Display
Locate the steering wheel toggle switches on the lower-left spoke. Use the up and down arrows to navigate the settings menu on the gauge cluster display. Select the "Settings" gear icon by pressing the "i/SET" button. Within this sub-menu, locate the "EyeSight" category.
Warning: Attempting to navigate these menus while the vehicle is in motion is restricted by the vehicle control module to prevent driver distraction. Always perform these adjustments while safely parked.
Step 2: Toggling Pre-Collision Braking and Adaptive Cruise
Once inside the EyeSight menu, you can toggle individual features. To suppress the Pre-Collision Braking system, highlight the specific feature and select "Off." Please note that on most Subaru models, this action is not a permanent "hard" disable. The system is designed to reset to the "On" state automatically upon the next ignition cycle.
Step 3: Deactivating Lane Departure Warning and Lane Sway
The Lane Departure Warning (LDW) and Lane Sway Warning can be deactivated using the physical button located on the overhead console near the map lights or the interior rearview mirror. Pressing and holding this button for approximately two to three seconds will trigger an audible chime and an illuminated indicator on the dashboard, signaling that the lane-monitoring components are suppressed.
Step 4: Understanding the Hard Reset Protocol
If you require a temporary shutdown for specific off-road conditions or heavy snow accumulation where the cameras are blinded, utilize the physical "EyeSight Off" switch if equipped on your console. If your model lacks a dedicated switch, you may trigger a temporary system fault by placing a non-permanent adhesive cover over the camera lenses; however, this is discouraged as it triggers an "EyeSight Disabled" warning light that remains persistent until the obstruction is removed.

Comparative Overview of EyeSight Component Behaviors
| Feature | Primary Function | Deactivation Method | System Reset Behavior |
|---|---|---|---|
| Pre-Collision Braking | Automatic emergency stop | MFD Settings Menu | Resets on Ignition Cycle |
| Adaptive Cruise Control | Maintains distance/speed | Steering Wheel Toggle | Resets on Ignition Cycle |
| Lane Keep Assist | Steering input correction | Center Console/Overhead | Retains State until Toggled |
| Lead Vehicle Start Alert | Notifies when traffic moves | MFD Settings Menu | Retains State until Toggled |
Common Field Failures and Troubleshooting Remedies
- Root Cause: "EyeSight Disabled" Warning Light Stays On.
- Actionable Fix: Check the windshield area directly in front of the stereo cameras for debris, ice, or excessive condensation. Clear the area with a microfiber cloth and ensure the dashboard is free of reflective objects, as solar glare can cause the system to self-disable.
- Root Cause: Settings Reset After Vehicle Restart.
- Actionable Fix: Recognize that Subaru programmed the system to default to "On" for insurance and safety rating compliance. There is no factory-authorized method to permanently disable the system without causing an permanent diagnostic trouble code (DTC) in the Engine Control Module (ECM).
- Root Cause: Audible Chimes Persist During Manual Deactivation.
- Actionable Fix: If you have turned off specific features but the vehicle continues to chime, verify that other safety systems, such as Blind Spot Detection (BSD) or Rear Cross-Traffic Alert (RCTA), are not also active. These systems often share the same alert frequency and may be mistaken for EyeSight notifications.
Frequently Asked Questions
Can a dealership permanently disable EyeSight for me?
No, authorized Subaru service centers cannot permanently disable the EyeSight system. Because the system is tied to the vehicle's crash safety certification and insurance rating, modifying it would violate federal safety protocols and void the manufacturer's warranty.
Is it safe to drive with EyeSight turned off?
Driving with EyeSight disabled is safe provided you maintain full manual control of the vehicle. You will lose active safety benefits such as pre-collision alerts, adaptive cruise control, and automated braking, requiring you to be more vigilant in traffic.
Why does EyeSight turn itself back on?
Subaru utilizes a "fail-safe" design philosophy that defaults all driver-assistance systems to the "On" position every time the ignition is cycled. This ensures that features like emergency braking are always active for the next driver.
Does blocking the cameras trigger a service light?
Yes, intentionally obstructing the stereo cameras will trigger a "Check EyeSight" warning message and illuminate the master warning light on the instrument cluster. This may also disable unrelated systems like cruise control entirely, as they rely on camera input for data.
Maintain your Subaru’s safety integrity by ensuring the EyeSight system is clear of obstructions and functioning within factory parameters. If you experience persistent issues with system activation, consult with a certified technician to perform a recalibration of the stereo camera array.
