In an information providing method for a vehicle, an engine is stopped automatically when a predetermined permission condition is satisfied in a state in which the vehicle is stopped by a brake operation executed by a driver. The permission condition is a brake operation amount of a brake having reached a predetermined brake operation amount. The driver is notified of support information prompting the driver to increase the brake operation amount when the permission condition is not satisfied after a predetermined time has elapsed since the vehicle was stopped. A braking force capable of maintaining a vehicle stop state is generated by a vehicle stop keeping control. The driver is notified of the support information when the brake operation amount decreases before the predetermined time has elapsed in a state in which the vehicle has been stopped by the brake operation and the vehicle stop keeping control is executed.
