WARNING: This page is about a different car, the 2003 Infiniti M45. However, it is still accessible from the selected car via links, so may be relevant.

The VACS (Voice-Activated Control System) provides a safe and convenient way of controlling vehicle systems such as the audio, auto A/C and navigation (if so equipped). The system is controlled by the PTT (Push to talk) button. Voice commands are picked up by a microphone. When giving a command, voice feedback will be heard through the speaker, and messages will be shown on the display. Voice feedback can be turned off. Personal directories of nametags for radio station presets can be created, and spoken command help is provided.
Refer to Owner's Manual for voice activated control system operating instructions.
