Abstract
A vehicle has a front grille, engine, engine compartment, power storage device, temperature sensor, shutter, heater and controller. The device can be electrically charged from an external power supply. The temperature sensor detects engine coolant temperature. The shutter is disposed in a transfer pathway of air drawn into the engine compartment via the front grille, and is switched between closed and open states. The heater is able to generate heat when receiving the electric power, raising the coolant temperature. The controller starts the engine when the coolant temperature is lower than a startup threshold value, drives the heater when the coolant temperature is lower than a first threshold value equal to or higher than the startup threshold value, until the coolant temperature becomes equal to or higher than the first threshold value, and drives the shutter to place the shutter in the closed state while the heater is driven.
