You look away for just a second and suddenly the vehicle in front of you has stopped. That's when the forward collision mitigation system comes to life. When it senses an impending impact, it will activate a combination of features to help prevent or reduce the severity of an accident. Forward collision mitigation is always looking ahead. Pedestrian impact prevention - An extra step toward safety. Pedestrians don't always stop, look, and listen, but with Pedestrian Impact Prevention, your vehicle is equipped to better see them and avoid them. This system constantly monitors the road ahead to identify and track pedestrians. It projects that image to an interior display screen, AND should an impact become likely, Pedestrian impact prevention takes steps to avoid a collision. Hands-off cruise control - Set it and forget it. Road trips used to be stressful. Cruise control only managed speed, but not distance or safety. Now with hands-off cruise control simply set your desired speed and let sensor technology maintain a safe distance between you and surrounding vehicles with minimal steering input from you. It slows you down; speeds you up and even keeps you in your own lane. Meet your ultimate co-pilot with hands-off cruise control.
