Adaptive Crusie Control


Summer 2014

As part of the Subaru of America, Inc. National Marketing Department, I’m regularly exposed to new Subaru vehicles and products and test them as they are introduced. When EyeSight,1the Subaru Driver Assist Technology, was introduced, it caught my attention because of its ability to look at the road ahead and control vehicle speed to correspond with the flow of traffic – a feature straight out of The Jetsons.


When in a car, I need to be the one in control. Since high school, I’ve always been the guy who drives – a matter of trust and control. At first, I was a bit apprehensive about driving a vehicle that was able to stop and start by itself and take that control away from me. I’ve had a clean driving record for more than 30 years, so naturally I was intrigued to see if EyeSight would be able to make better driving decisions than
I could. 

But Subaru engineers have always been innovators, and a feature that helps make our vehicles even safer is definitely worth a try. Especially when it’s acclaimed by the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS).

I took a 2014 Legacy 2.5i Limited for a Sunday road trip. The goal was to test EyeSight in a variety of circumstances without endangering myself, the vehicle, or any other vehicles on the road. I decided to use the Adaptive Cruise Control as much as possible on a route that combined inner-city and suburban expressways, back roads, and a major interstate highway. 


I’m not one to read instruction manuals, even though I realize I should, especially for products that incorporate new technology. Nonetheless, I just hopped in the car and set out across the bridge into Philadelphia, Pennsylvania. Once on the Schuylkill Expressway, which runs through the heart of the city and into the western suburbs, I engaged the EyeSight Adaptive Cruise Control. 

The Schuylkill is the primary artery for traffic leaving the city, and on this Sunday morning, lots of drivers wanted to get out of Philly. I set the cruise control to the pace of overall traffic flow – approximately 55 mph – jumped in, and let the car do the work. 

The EyeSight Adaptive Cruise Control gives the driver the benefits of cruise control while actively monitoring the road ahead. It warns the driver and automatically brakes when needed to maintain a safe following distance from the vehicle ahead. While the vehicle is stopped, the Lead Vehicle Start Alert notifies the driver when the vehicle in front has started moving and the EyeSight vehicle has not. A tap of the accelerator or the RES+ switch on the steering wheel will start the vehicle and accelerate it to the set speed. 

In the 20 miles or so that I was on the expressway, the pace varied from upward of 65 mph to a grinding halt, then back up to 65. After EyeSight brought the car to its first grinding halt, I was admittedly a little white-knuckled. While stopped, I noticed the button on the steering wheel that adjusts the following distance. I set it to the longest of the three increments and took off again.

Throughout the remainder of the almost 200 miles of the trip on familiar roads, I drove with the system on various types of roadways, ranging from open highway to congested highway to stop-and-go driving with traffic lights. On the open highway, the system acted just like cruise control – the car maintained the set speed. 

The last leg of the trip was on an incredibly congested part of I-95 through Maryland, Delaware, and back toward Philadelphia. The only thing I really did during this part of the drive was steer. EyeSight maintained speed with the flow of traffic, slowed down when cars from other lanes moved in front of me, and kept a safe distance from that car in front. 


The EyeSight Adaptive Cruise Control function is a revolutionary camera system designed to support – not replace – the driver, who still needs to be engaged in controlling the vehicle. EyeSight is a secondary means of helping a person drive safely. While I was never in a position where a collision was inevitable, EyeSight made me more comfortable by letting me make fewer decisions about speed control and maintaining pace with traffic flow. It gave me more confidence in the event that I was ever unintentionally put into a position where a crash seemed inevitable.

Usually, arriving home from this same drive requires me to take a few minutes to chill out. I-95 can be mentally challenging. However, I think that the Adaptive Cruise Control gave me more confidence and allowed me to relax a little more. I love to drive, and this experience with EyeSight has given me another reason to do so, even in the most challenging situations.

EyeSight is an available option on 2015 Forester and will be available as an option on 2015 Legacy and Outback in fall of 2014. 

In future issues of Drive, I’ll continue to explore the functions and new features of Subaru EyeSight and more new safety features. 


EyeSight uses a combination of throttle and brake management when needed. 

Have your vehicle’s brake system inspected by a Subaru retailer with every tire rotation. Using Genuine Subaru Brake Pads and Rotors is especially important on vehicles with EyeSight, as the system is calibrated based on their part specifications.


Read more about EyeSight in the Fall 2012 issue of Drive. 


The system works between 25 mph and 90 mph.

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 state law requires registration stickers or other items in this area, install them as low as possible.

Adaptive Cruise Control can be set and road speed can be changed in increments of plus or minus 1 mph to 5 mph.

Legacy and Outback Limited models have a unique, center-mounted color LCD screen that accommodates EyeSight alerts and functions, when equipped.

To prevent damage, disable EyeSight when entering a car wash.

Technology effectiveness depends on many factors such as vehicle maintenance, weather and road conditions. See Owner’s Manual for complete details on system operation and limitations. Please remember to turn off EyeSight when going through a car wash.
