It uses fuel and runs the engine at least until reaching a coolant temperature of 130. The car could simply require more brake effort to mechanically waste speed into heat, but instead the car starts up for no reason that has been adequately explained to me.
Engine also comes on above 61 MPH. The trick to bypass that action is to shift to N. It's meant to come on above a certain speed to keep the motors within safe RPM limits, but they built a massively conservative margin in. I've coasted at 75 MPH down a hill without issue.
