Program for operating vehicle from outside vehicle

A program stored in a mobile terminal including a processor, a display, and a communication device, the program being configured to operate an operation target vehicle from outside with use of the mobile terminal, the operation target vehicle being registered in advance, the program causing the processor to execute:

• a step of estimating a distance from the mobile terminal to the operation target vehicle;
• a step of determining whether or not the estimated distance is less than a prescribed threshold;
• a step of receiving an operation instruction from the communication device with respect to the operation target vehicle when the estimated distance is less than the threshold, the operation instruction being a moving instruction;
• a step of causing the communication device to output a signal instructing an operation in response to the operation instruction received from the communication device;
• and
• a step of making a notification that the mobile terminal is out of an operable range of operating the operation target vehicle when the estimated distance is equal to or more than the threshold.
