Pedestrian Warning System
The Pedestrian Warning System (if equipped) causes Model 3 to emit sound when driving below approximately 24 km/h (15 mph) or while driving in reverse. Electric vehicles operate quietly and this sound helps to alert pedestrians of your oncoming vehicle. The sound, which activates whenever the setting is turned on (if equipped) and Model 3 is shifted out of Park, gets louder as speed increases.
For vehicles manufactured prior to approximately November 2021: In situations where you need to turn the sound off (such as in stop and go highway traffic), touch . The sound is paused for the current drive only. On your next drive, the sound automatically turns back on. The switch may not be available for vehicles manufactured after this date.
