Pedestrian Warning System
The Pedestrian Warning System (if equipped) causes Model 3 to emit sound when driving below approximately 33 km/h (21 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 Model 3 is shifted out of Park, gets louder as speed increases.
The Pedestrian Warning System may not be available in vehicles manufactured prior to approximately July 1, 2021.
If sound cannot be heard, pedestrians may not be aware of your oncoming vehicle, which may increase the likelihood of a collision resulting in serious injury or death. If the Pedestrian Warning System is not operating, immediately contact Tesla.
