..How Forward Collision Warning Works If Model S is equipped with Autopilot, a camera mounted on the windshield behind the interior rear view mirror and a radar sensor in the center of the front grill monitor the area in front of Model S for the presence of a vehicle, bike or pedestrian. If a collision is considered likely unless you take immediate corrective action, Forward Collision Warning is designed to provide visual and audible warnings. The cameras and sensors associated with Forward Collision Warning are designed to monitor an approximate area of up to 525 feet (160 meters) in the driving path, as illustrated below.
Warning: The area being monitored by Forward Collision Warning can be adversely affected by road and weather conditions (see Limitations on page 58). Use appropriate caution when driving. Caution: If your Model S is equipped with Forward Collision Warning, you must take your vehicle to Tesla Service if a windshield replacement is needed. Failure to do so can cause Forward Collision Warning to malfunction.
Warning: Forward Collision Warning does not operate when Model S is traveling less than 4 mph (7 km/h). Warning: Forward Collision Warning is designed only to provide visual and audible alerts (see Visual and Audible Feedback on page 58). It does not attempt to apply the brakes or decelerate Model S. When seeing and/or hearing a warning (described below), it is the driver's responsibility to immediately take an appropriate action.
Warning: Forward Collision Warning is for guidance purposes only and is not a substitute for attentive driving and sound judgement. Always keep your eyes on the road when driving and never depend on Forward Collision Warning to warn you of a potential collision. Several factors can reduce the performance of Forward Collision Warning, causing either unnecessary, invalid, inaccurate, or missed warnings (see Limitations on page 58). Depending on Forward Collision Warning to warn you of a potential collision can result in serious injury or death. Visual and Audible Feedback When a collision with a vehicle, bicycle, or pedestrian is considered likely unless immediate action is taken, Forward Collision Warning is designed to sound an audible alert and display a collision warning in the center of the instrument panel. Warnings cancel automatically when the risk of a collision has been reduced (for example, you have decelerated or stopped Model S, or a vehicle in front has moved out of your driving path). Warning: Forward Collision Warning may provide a warning in situations where the likelihood of collision may not exist. Stay alert and always pay attention to the area in front of Model S so you can anticipate whether any action is required. Controlling Forward Collision Warning To turn Forward Collision Warning off or adjust its sensitivity, touch Controls > Settings > Driver Assistance > Forward Collision Warning. Instead of the default warning level of Medium, you can turn the warning Off, or you can choose to be warned Late or Early. Note: Your chosen setting is retained until you manually change it. It can also be saved in your driver profile. Limitations Forward Collision Warning cannot always detect vehicles, bikes, or pedestrians, and you may experience unnecessary, inaccurate, invalid or missed warnings for many reasons, particularly if: • The road has sharp curves.
• Visibility is poor (due to heavy rain, snow, fog, etc.). • Bright light (oncoming headlights or direct sunlight) is interfering with the camera's view. • The radar sensor in the center of the front grill is obstructed (dirty, covered, etc.). • The windshield area in the camera's field of view is obstructed (fogged over, dirty, covered by a sticker, etc.).
Warning: The list above does not represent an exhaustive list of situations that may interfere with proper operation of Forward Collision Warning. Forward Collision Warning may fail to provide warnings for many other reasons. To avoid a collision, stay alert and always pay attention to the area in front of Model S so you can anticipate the need to take corrective action as early as possible.
