Abstract
A vehicle includes an engine, a climate control system, a cabin, and a controller. The controller is programmed to, in response to the climate control system supplying heat to a vehicle cabin and receiving a request for an economy mode, decrease an engine coolant temperature engine start threshold. The controller is further programmed to, in response to the engine coolant temperature becoming less than the threshold, start the engine.
