The 2023 Subaru Crosstrek's Lane Departure Prevention uses EyeSight to help prevent unintended lane departures through steering assistance. When this feature shows as disabled, understanding EyeSight's requirements helps identify whether conditions or a fault is responsible.
Lane Departure Prevention Function
Lane Departure Prevention is part of EyeSight that monitors lane markings and provides steering torque when drift is detected without turn signal activation. It's more active than basic Lane Departure Warning, actually helping correct your course rather than just alerting you.
Why the Feature May Be Disabled
Several conditions disable Lane Departure Prevention. Manual disable through settings turns off the feature. EyeSight camera obstruction disables all EyeSight functions including lane departure features. Speed outside operating range prevents activation. System faults cause feature disable with accompanying warnings.
EyeSight System Status
Lane Departure Prevention depends on overall EyeSight functionality. If EyeSight is disabled due to camera obstruction or other issues, Lane Departure Prevention is also unavailable. Check the overall EyeSight status indicator to understand system health.
Restoring the Feature
If manually disabled, re-enable through settings. If EyeSight is unavailable, address that underlying issue first—usually by cleaning cameras. If specific faults are indicated, professional diagnosis identifies the problem.
