Alerts and helps to assist you if the system determines a possibility of your vehicle unintentionally crossing over detected lane markings and/or leaving the roadway altogether while driving between 45-90 mph (72-145km/h).
If your vehicle is getting too close to detected lane markings without a turn signal activated, the system, in addition to a visual alert, applies steering torque and alerts you with rapid vibrations on the steering wheel, to help you remain within the detected lane. Braking is applied only when the lane markings are solid continuous lines.
