Operational Notes
The system works up to 87 miles per hour.
EyeSight will override Brake Assist when not braking hard enough to help prevent a rear-end collision.
If 40 percent or less of the vehicle ahead is in the EyeSight vehicle’s path, the system assumes that it can be avoided and does not issue warnings or activate the brakes.
To have the front windshield replaced or repaired, contact a Subaru retailer. Do not install a front windshield other than a genuine Subaru front windshield. The stereo cameras may not be able to detect objects accurately and the EyeSight system may not operate properly.
The windshield of an EyeSight-equipped vehicle must be clear for the system to work properly – window tints, aftermarket coatings, toll-road transponders, and cracks may hinder operation. Broken windshields must be replaced with Subaru windshields.
If fingerprints or spray from glass cleaner touches the EyeSight system’s lenses, they must be replaced.
Cruise control speed changes via the +/- switch move in 5-mile-per-hour increments, unless the button is held down, which then changes speed in 1-mile-per-hour increments.
Under most conditions, the EyeSight system activates the brake lights.
Legacy and Outback Limited models sport a unique center-mounted color LCD that accommodates EyeSight alerts and functions, when equipped.


How Eyesight Works


Each of the two cameras scans the road through a 25-degree arc from the vehicle’s centerline. A full horizontal sweep takes approximately 0.1 second.


A processor in the EyeSight housing determines the perceived distances between objects in the road from one camera’s image to the next, much like your two eyes perceive an object’s location. (Try this: When you look at an object and close one eye, then open it and close the other, you perceive a distance between where each eye sees an object. That’s what EyeSight does with the cameras.)


As it scans, the EyeSight system recognizes if that distance is changing. If it grows, the vehicle is approaching the object. If the distance shrinks, it’s moving away from the vehicle.


The system recognizes objects moving in the same direction of travel – not across the vehicle’s path.


The EyeSight processor determines if the closing speed presents a dangerous situation, and it is networked with engine, transmission, and chassis system processors that enable actions to be taken. Networked systems and sensors include those for the Anti-lock Braking System, Vehicle Dynamics Control System, Brake Assist, steering-angle sensor, and the gauge cluster in the instrument panel.
