Interrogative To New 2012 “vee” Owners – Is the VPNS function activated and noticeably emitting “Proximity Notification” sounds in your new ride? I did a “Parking Lot Test” of the VPNS with my "V" For "V"ictory petrol warfighter in its “stealth,” EV propulsion, mode moving a under 15 MPH, and with my wife as the “Blind Pedestrian” listener. She heard no “the Prius' noise-maker will also raise or lower the pitch of the hum based on the vehicle's speed. This gives pedestrians the ability to gauge the speed and direction of the Prius, says Toyota” or other noise, sound, “Space Ship” sound, “White Noise,” or auditory etceteras being emitted by our new fuel-sipper. Additionally, the security guard at the entrance gatehouse recently commented as I passed through on “stealth” EV-Electric Power, “Your car is super quiet.” I am wondering if Toyota/Local Dealer/Southeastern Toyota Regional has the VPNS sound deactivated for pre-sale marketing purposes. That is, so the VPNS warning sound cannot be heard during test drives of the “v” by prospective buyers who might be deterred from purchasing a $30,000 car with built-in OEM “noise maker.” I am going in to have some dealer-owed, post-sale “We Owes” installed in my “vee” by my local Toyota Dealer in a few days, and will have my “silent” VPNS “fixed/activated” when it is in there. FWIW FYI NOTE: The Pedestrian Safety Enhancement Act of 2010, sponsored by Sen. John Kerry [D-MA], was passed by the Senate 12/9/2010, passed the House 12/16/2010, and was signed into law by President Obama Jan 4, 2011. The new law requires the National Highway Traffic Safety Administration (NHTSA) to be the “Noise Cop” for new, quiet EVs (Electric Vehicles). All 2012 model year and beyond Prius hybrids and plug-in hybrid electric vehicles (PHEV) sold in the U.S. have OEM, factory–installed Vehicle Proximity Notification System (VPNS) “noise makers,” and are and will be NHTSA compliant.
