Lane Keeping Assist System (LKAS)
The Lane Keeping Assist System (LKAS) is a convenience feature that works proactively to help keep the vehicle centered in a detected lane by providing steering assistance. A camera located between the windshield and the rearview mirror can detect lane separation markings, and as the vehicle moves from the center of the lane, the Electric Power Steering system applies torque to return the vehicle to the middle of the lane. The farther it gets from the center, the more torque is applied. The Lane Keeping Assist System (LKAS) is intended to warn and assist the driver, and is not a substitute for steering the vehicle. The driver must keep their hands on the wheel for the system to operate.
Lane Keeping Assist System (LKAS) only assists driver in maintaining proper lane position when lane markings are identified without a turn signal in use and can only apply mild steering torque to assist. LKAS may not detect all lane markings; accuracy will vary based on weather, speed, and road conditions. System operation affected by high interior heat. Driver remains responsible for safely operating vehicle and avoiding collisions.
