Blind spot monitoring systems like Subaru Blind Spot Detection employ a set of sensors including radar and cameras, often positioned on the mirrors and/or rear bumper. These sensors constantly monitor adjacent lanes and nearby objects relative to a driver’s designated blind spot zone. When another vehicle enters this area, the sensors detect it and trigger an alert—typically a blinking light on the corresponding side mirror, sometimes accompanied by a beeping or clicking noise. This lets the driver know they should use added caution when shifting lanes or merging. In most equipped Subaru models, the warning light is located on the inner rim of each side mirror.
The Subaru Blind Spot Detection system engages automatically, without any action from the driver. However, if you need to disable the system for any reason, simply toggle a switch located in the dash area and/or on the infotainment screen. In many Subaru models, the Blind Spot Detection system works in conjunction with a similar feature called Rear Cross-Traffic Alert. Both features are controlled with a single switch or touchscreen toggle.
Rear Cross-Traffic Alert is just one of several systems in a Subaru that utilize the same basic principles and technology as Blind Spot Detection to protect drivers in different ways. Other key systems that use smart sensors paired with a warning system or helpful intervention include Lane Centering, EyeSight® Driver Assist Technology, Reverse Automatic Braking, and our DriverFocus® Distraction Mitigation System.
