Methods and systems are provided for restarting an engine following an engine idle-stop. In one example, a method may include, following a first unsuccessful engine restart attempt, prompting a driver, via a human machine interface (HMI) to apply a brake pedal and upon application of the brake pedal, carrying out one or more restart attempts. If the driver does not apply the brake pedal within the threshold duration, the driver may be prompted to manually restart the engine.
