• The road has sharp curves or significant changes in elevation.
• Road signs and signals are unclear, ambiguous, or poorly maintained.
• Visibility is poor (due to heavy rain, snow, hail, etc. or poorly lit roadways at night)
• You are driving in a tunnel or next to a highway divider that interferes with the view of the camera(s)
• Bright light (such as from oncoming headlights or direct sunlight) interferes with the view of the camera(s).

• Autosteer is unable to accurately determine lane markings. For example, lane markings are excessively worn, have visible previous markings, have been adjusted due to road construction, are changing quickly (lanes branching off, crossing over, or merging), objects or landscape features are casting strong shadows on the lane markings, or the road surface contains pavement seams or other high-contrast lines.
• Visibility is poor (heavy rain, snow, fog, etc.) or weather conditions are interfering with sensor operation.
• A camera(s) or sensor(s) is obstructed, covered, or damaged.
• Driving on hills.
• Approaching a toll booth.
• Driving on a road that has sharp curves or is excessively rough.
• Bright light (such as direct sunlight) is interfering with the view of the camera(s).
• The sensors (if equipped) are affected by other electrical equipment or devices that generate ultrasonic waves.
• A vehicle is detected in your blind spot when you engage the turn signal.
• Model Y is being driven very close to a vehicle in front of it, which is blocking the view of the camera(s).

• 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.

• Do not use Autopark if anything, such as a ball hitch, bike rack, or trailer, is attached to the tow hitch. Autopark may not stop for hitches when parking between or in front of other vehicles.
• Never depend on Autopark to find a parking space that is legal, suitable, and safe. Autopark may not always detect objects in the parking space. Always perform visual checks to confirm that a parking space is appropriate and safe.
• When Autopark is actively steering Model Y, the steering wheel moves in accordance with Autopark's adjustments. Do not interfere with the movement of the steering wheel. Doing so cancels Autopark.
• During the parking sequence, continually check your surroundings. Be prepared to apply the brakes to avoid vehicles, pedestrians, or objects.
• When Autopark is active, monitor the touchscreen to ensure that you are aware of the instructions that Autopark is providing.

Autopark is particularly unlikely to operate as intended in these situations:

• The road is sloped. Autopark is designed to operate on flat roads only.
• Visibility is poor (due to heavy rain, snow, fog, etc.).
• The curb is constructed of material other than stone, or the curb cannot be detected.
• The target parking space is directly adjacent to a wall or pillar (for example, the last parking space of a row in an underground parking structure).
• One or more of the sensors (if equipped) or cameras is damaged, dirty, or obstructed (such as by mud, ice, or snow, or by a vehicle bra, excessive paint, or adhesive products such as wraps, stickers, rubber coating, etc.).
• Weather conditions (heavy rain, snow, fog, or extremely hot or cold temperatures) are interfering with sensor (if equipped) operation.
• The sensors (if equipped) are affected by other electrical equipment or electrical interference.
