ADAS: Lexus HS is equipped with numerous safety systems, such as radar-guided, active, cruise control and various levels of stability and traction control. At any given time, up to five cameras are working to keep the driver safe.
Lane Keep Assist (LKA) uses a camera to detect lane markers and a second camera to detect the driver’s head movements. If the HS drifts out of its lane without using a turn signal and the system determines that the driver is distracted, LKA will nudge the steering wheel to correct the vehicle’s course. Drivers can easily push through the LKA’s inputs if, in fact, the lane change is intentional. We tested the system on a clear highway and, as promised, the HS will keep itself in its lane if allowed to drift. The feedback is gentle, but noticeable, and definitely got our attention, which we think is the point.
Telematics: The Lexus HS 250h is slated to be the first vehicle to offer the all-new telematics system Lexus Enform with Safety Connect, available by subscription on the dedicated luxury hybrid sedan when it goes on sale in late summer. Safety Connect, the cornerstone of the services, is available on both non-navigation and navigation-equipped HS250h vehicles and offers four fundamental safety and security features: Automatic Collision Notification, Stolen Vehicle Location, Emergency Assistance Button (SOS), and enhanced Roadside Assistance, which adds GPS data to the already included warranty-based Lexus roadside service.
