In this tutorial, we learn how to operate dynamic radar cruise control in the 2010 Prius. This supplements the conventional cruise control with a vehicle to vehicle cruise control. The radar system sees the car ahead and is less effected by bad weather conditions. The driver can select short, medium, or long driving distances. When cruising at a set speed that is faster than the car ahead, the vehicle will slow down to the speed of that car. A warning will be sounded to tell the driver to take further control if a break is needed further from this. Once the road is clear, the vehicle will slowly accelerate to the previously selected cruising speed.
