Now, with adaptive cruise control, simply set your desired speed and let sensor technology maintain a safe distance between you and the vehicle ahead. Adaptive cruise control; your ultimate co-pilot.Safety and Security Forward collision mitigation - Forward thinking. 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. Rear camera - Watching your back! The rear camera helps you see obstacles and hazards you otherwise couldn't by showing enhanced images of what is behind you. The rear camera is an extra set of eyes that's both convenient and safe.Technology and Telematics Mobile hotspot - WiFi on the fly. Connect your devices to the Internet through your vehicles private mobile hotspot and take the internet wherever your journey takes you, without eating up your data allowance.
