a second operator input device electrically coupled to the at least one control unit, the at least one control unit being operative to power on the electrical system without starting the engine in response to detecting, while the electrical system and the engine are each in the powered off state, both (1) an actuation of the second operator input device and (2) a lack of actuation of the first operator input device, and

the second operator input device is configured to power off the electrical system when at least one of a first condition and a second condition is present, where the first condition is a vehicle speed equal to zero and the second condition is the engine in the powered off state, and the second operator input device is further configured to power off both the electrical system and the engine when the electrical system and the engine are both in a powered on state.

2. The vehicle of claim 1 , wherein in response to detecting an actuation of the first operator input device after powering on the electrical system and while the engine is in the powered off state, the at least one control unit is operative to start the engine.

3. The vehicle of claim 1 , wherein the at least one control unit is further operative to maintain the electrical system in the powered off state when the duration of the actuation of the first operator input device is less than the threshold duration.

4. The vehicle of claim 1 , further including a wireless security device detectable by the at least one control unit, the at least one control unit being operative to determine whether the wireless security device is within a range of the vehicle in response to detecting the actuation of the first operator input device, the at least one control unit powering on the electrical system and starting the engine when both the wireless security device is present and the duration of the actuation of the first operator input device is longer than the threshold duration.

5. The vehicle of claim 4 , wherein the at least one control unit determines that the wireless security device is within the range by transmitting a wireless signal to the wireless security device and receiving a return signal from the wireless security device.

6. The vehicle of claim 4 , wherein the at least one control unit is configured to determine when the wireless security device is outside the range of the vehicle, and the at least one control unit is configured to power off the engine when the wireless security device is outside the range of the vehicle and the vehicle is not moving for a predetermined time period.

7. The vehicle of claim 6 , wherein the at least one control unit is configured to power off the engine when the wireless security device is outside the range of the vehicle and the vehicle is stationary for a first predetermined time period, and the at least one control unit is configured to power off the electrical system when the wireless security device is outside the range of the vehicle and the vehicle is stationary for a second predetermined time period, and the first predetermined time period is less than the second predetermined time period.

8. The vehicle of claim 1 , wherein the first operator input device includes a pushbutton, and the duration of the actuation of the first operator input device corresponds to a continuous time that the first operator input device is depressed by the operator.

9. The vehicle of claim 1 , wherein the at least one control unit includes an engine control unit for controlling operation and throttle demands of the engine and a vehicle control unit for controlling the plurality of electrical components of the electrical system, and the vehicle control unit powers on the electrical system and instructs the engine control unit to start the engine when the duration of the actuation of the first operator input device is longer than the threshold duration.

10. A method of controlling the startup of a vehicle carried out by at least one control unit of the vehicle, the method including:

detecting an actuation of a first operator input device of the vehicle while an electrical system and an engine of the vehicle are each in a powered off state;

monitoring a duration of the actuation of the first operator input device;

powering on the electrical system without starting the engine in response to detecting, while the electrical system and the engine are each in the powered off state, both (1) an actuation of a second operator input device of the vehicle and (2) a lack of actuation of the first operator input device;

maintaining at least the engine in the powered off state in response to the duration of the actuation being less than the threshold duration; and

powering off at least one of the electrical system and the engine, using the second operator input device, according to any of the following conditions:

powering off the electrical system when a vehicle speed equal to zero;

powering off the electrical system when the engine is in the powered off state; and

powering off both the electrical system and the engine when both the electrical system and the engine are in a powered on state.

11. The method of claim 10 , wherein the maintaining further includes maintaining the electrical system in the powered off state in response to the duration of the actuation of the first operator input device being less than the threshold duration.

12. The method of claim 10 , further including, after powering on the electrical system in response to detecting the actuation of the second operator input device and while the engine is in the powered off state, starting the engine in response to detecting an actuation of the first operator input device.

13. The method of claim 10 , further including

determining whether a wireless security device is within a range of the vehicle in response to detecting the actuation of the operator input device, and

powering on the electrical system and starting the engine when both the wireless security device is present and the duration of the actuation of the first operative input device is longer than the threshold duration.

14. The method of claim 13 , further comprising determining whether the wireless security device is outside the range of the vehicle, and powering off the engine when the wireless security device is outside the range of the vehicle and the vehicle is stationary for a first predetermined time period.

15. The method of claim 14 , further comprising powering off the electrical system when the wireless security device is outside the range of the vehicle and the vehicle is stationary for a second predetermined time period, and the first predetermined time period is less than the second predetermined time period.
