Subaru EyeSight Driver Assist Technology Quick Reference Guide

WRX 2016

What is EyeSight?

EyeSight is a driving support system that uses a range of functions to assist the driver in making decisions to provide for more safe and comfortable driving and to reduce driver fatigue. It is designed to help assist drivers, not replace them.

How Does EyeSight Work?

EyeSight uses stereo cameras to process stereo images and identify objects such as the vehicle in front, obstacles, traffic lanes and other items. Under the right circumstances, EyeSight will apply the brakes or decrease the throttle to help reduce the severity of, or help avoid a collision.

EyeSight Functions

Pre-Collision Braking System

This function can recognize an impending collision with a vehicle or obstacle in front of the EyeSight vehicle, alert the driver and even automatically apply the brakes to help avoid a collision or minimize the impact when a collision is inevitable.

Pre-Collision Brake Assist

If EyeSight recognizes an impending collision with a vehicle or obstacle in front of the EyeSight vehicle, and the driver is applying the brakes but not with enough brake pedal force, Pre-Collision Brake Assist automatically applies up to full braking pressure in order to try to shorten braking 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 them. 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 and Lane Sway Warning

Lane Departure Warning alerts drivers when they unintentionally move out of their travel lane. It takes no corrective vehicle action other than issuing visual and audible warnings.

Lane Sway Warning acts in a similar way, detecting unusual back and forth vehicle movement within the driver's lane of travel that is usually indicative of a drowsy driver.

Adaptive Cruise Control and Lead Vehicle Start Alert

This function combines the benefits of Cruise Control with active monitoring of the road ahead by EyeSight. It issues warnings and activates automatic braking when needed.

Adaptive Cruise Control can regulate vehicle speed in order to keep a safe following distance from the vehicle ahead. It does not replace Conventional Cruise Control, which can still be used when desired. Lead Vehicle Start Alert notifies the driver when the vehicle in front has started moving but the EyeSight driver's vehicle has not.

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 20 mph, it may not be possible to avoid a collision.
Sun glare, inclement weather such as heavy rain, 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.
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.
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 Cameras Precautions

The stereo camera lenses are precision components. When the system detects that the stereo 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.
Do not attempt to remove or disassemble the stereo cameras.
Do not attempt to change the position where the stereo 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 cameras. Failure to do so may affect the stereo 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

Standard

There must be no oil film, dirt, scratch or fogging that obstructs the forward visibility of the stereo camera.

Do not stick or attach aftermarket parts on the prohibited areas shown in gray on the windshield and top of the dashboard.

Even outside the prohibited area, if the 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-type mirror: This will affect the visibility of the stereo camera, causing the function not to operate correctly.
Placement of navigation unit, ETC or other things on the dashboard: These things may be reflected on the windshield glass, affecting the recognition of the stereo camera, thus causing the function not to operate correctly.
