To ensure a clear picture, the camera lens must be clean and free of obstructions. Remove any build-up of dirt or debris by spraying water onto the camera lens with a spray bottle or pressure washer.
CAUTION: Do not attempt to remove dirt or debris by wiping an exposed lens with your hands or a cloth. This debris can damage the surface of the lens when rubbed against it during wiping.
CAUTION: Do not use chemical-based or abrasive cleaners. Doing so can damage the surface of the lens.
Pedestrian Warning System
The Pedestrian Warning System (if equipped) causes Model S to emit sound when driving below approximately 19 mph (32 km/h) 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 S is shifted out of Park, gets louder as speed increases.
WARNING: 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.
