In control for a vehicle provided with a transmission in which a speed or shift range is changed by a shift operation performed by a driver, and a shift indicator that indicates a shift operation into an optimum speed or shift range selected based on a running state of the vehicle to the driver, it is determined whether an amount of fuel remaining in a fuel tank (64) is low, and if it is determined that the amount of fuel remaining is low, a speed or shift range set in advance such that priority is given to fuel efficiency performance over power performance is selected as the optimum speed or shift range based on the running state of the vehicle (10).
