Full Self-Driving (Supervised) Limitations
Limitations
The Driver Monitoring System (DMS) is a support feature and may not operate perfectly in all conditions. The DMS may issue alerts when the driver is attentive, or may fail to issue alerts when the driver is inattentive, misusing the system, or engaging in extreme or unusual behavior. You must remain attentive and responsible for safe vehicle operation at all times while using FSD (Supervised) and should not rely on the DMS to define or validate your behavior. The absence of a warning does not mean it is safe or acceptable to disengage from the driving task or to neglect the driver's responsibilities. You are always responsible for safe vehicle operation.
- System may not always detect or appropriately react to pedestrians, cyclists and other road users. Always pay attention, and if necessary, immediately take control of the driving task to ensure safety.
- System may not always detect or appropriately react to present or emerging animals on the road. Always pay attention, and if necessary, immediately take control of the driving task to ensure safety.
- System may not always follow traffic rules and traffic controls, select the proper lane of travel, or give priority to emergency vehicles. Always pay attention, and if necessary, immediately take control of the driving task to ensure safety.
- System may operate at speed that may not be appropriate for road conditions, such as poor road surface conditions, rain, fog, snow, ice, debris and related conditions. Always pay attention, and if necessary, immediately take control of the driving task to ensure safety.
- System may not always signal or indicate ahead of a maneuver, such as lane change, turning and entries of exits of roundabouts. Always pay attention, and if necessary, immediately take control of the driving task to ensure safety.
- System may not be able to detect objects due to camera occlusion, angle, or coverage limitations. Always pay attention, and if necessary, immediately take control of the driving task to ensure safety.
- System may have limited visibility of objects due to their position, distance, camera occlusion or coverage limitations. Always pay attention, and if necessary, immediately take control of the driving task to ensure safety.
Warnings and Cautions
- Interactions with pedestrians, bicyclists, and other road users.
- Unprotected turns with high-speed cross traffic.
- Multi-lane turns.
- Simultaneous lane changes.
- Narrow roads with oncoming cars or double-parked vehicles.
- Rare objects such as trailers, ramps, cargo, open doors, etc. protruding from vehicles.
- Merges onto high-traffic, high-speed roads.
- Debris in the road.
- Construction zones.
- High curvature roads, particularly at fast driving speeds.
Visibility is critical for Full Self-Driving (Supervised) to operate. Low visibility, such as low light or poor weather conditions (rain, snow, direct sun, fog, etc.) can significantly degrade performance.
The list above represents only a fraction of the possible scenarios that can cause Full Self-Driving (Supervised) to make sudden maneuvers and behave unexpectedly. In fact, Model Y can suddenly swerve even when driving conditions appear normal and straight-forward. Stay alert and always pay attention to the roadway so you can anticipate the need to take corrective action as early as possible. Remember that this is an early access feature that must be used with extra caution.
