Abstract: A vehicle location system includes a vehicle-based communication unit having a processor. The processor is configured to analyze request signals from a portable communication device. A first audible output device is configured to generate a first audible sound. A second audible output device is configured to generate a second audible sound. The sound generated by the second audible output device is a greater sound pressure than the first audible output device. The processor selectively enables one of the first audible output device and second audible output device based on the processor comparing a proximity characteristic of the request signals to a predetermined threshold.

Abstract: An unattended-vehicle engine-idling system controls a vehicle powertrain in a non-motive mode with the engine running. An ignition switch operables with a removable ignition key. A control circuit has multiple states including a PREARMED state which is entered when the powertrain is in the motive mode and the user generates a manual activation signal. An ARMED state is entered when the transmission is in Park and holds an ignition switch status signal at RUN. An ACTIVE state is entered when the ignition switch is moved to the Accessory or Off positions or the key is removed. The powertrain is switched to non-motive mode and the switch status signal stays at RUN. A DISARMED state is entered in response to a manual deactivation signal generated independently of the ignition switch. In the DISARMED state, the ignition switch status signal corresponds with the ignition switch position, thereby turning off the engine.
