Pedestrians don't always stop, look, and listen, but with Pedestrian Impact Prevention, your vehicle is equipped to better see them and avoid them.

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. Brake assist - Stop right there. Something jumps out into the middle of the road and you need to stop now! With brake assist, you will. It uses the speed of the brake pedals travel to sense panic braking, then applies all available power to boost your stopping power.
