Claim 9:
10. A method of controlling a utility vehicle, comprising:
storing electric power in a lithium battery of the utility vehicle;
operating a motor controller of the utility vehicle in a normal mode in which the motor controller provides electric power from a lithium battery of the utility vehicle to an electric motor of the utility vehicle to turn one or more ground engaging members of the utility vehicle,
after operating the motor controller in the normal operating mode, operating the motor controller in a walkaway mode in which the motor controller configures the electric motor to provide braking torque;
receiving an accelerator signal from an accelerator pedal, the accelerator signal indicating a current amount of pedal depression encountered by the accelerator pedal; and
entering the walkaway mode when the accelerator signal indicates that the accelerator pedal is not depressed; and
wherein the motor controller is constructed and arranged to enter the walkaway mode when a keyed switch of the utility vehicle is set to an OFF position, the keyed switch being electronically coupled with a battery management system (BMS) of the lithium battery.
