Warning: Never depend on Park Assist to inform you if an area you are approaching is free of objects and/or people. Several external factors can reduce the performance of Park Assist, causing either no readings or false readings (see Limitations and False Warnings on page 53). Therefore, depending on Park Assist to determine if Model 3 is approaching an obstruction can result in damage to the vehicle and/or objects, and can potentially cause serious injury. Always inspect the area with your own eyes. When reversing, perform shoulder checks and use all mirrors. Park assist does not detect children, pedestrians, bicyclists, animals, or objects that are moving, protruding, located too far above or below the sensors, or too close or too far from the sensors. Park Assist is for guidance purposes only and is not intended to replace your own direct visual checks. It is not a substitute for careful driving.

Limitations and False Warnings The parking sensors may not function correctly in these situations:
• One or more of the parking sensors is damaged, dirty, or covered (such as mud, ice, or snow).
• The object is located below approximately 8 inches (20 cm) (such as a curb or low barrier). Caution: Shorter objects that are detected (such as curbs or low barriers) can move into the blind spot of the sensors. Model 3 cannot alert you about an object while it is in the blind spot of the sensors.
• Weather conditions (heavy rain, snow, or fog) are interfering with sensor operation.
• The object is thin (such as a sign post).
• A sensor’s operating range has been exceeded.
• The object is sound-absorbing or soft (such as powder snow).
• The object is sloped (such as a sloped embankment).
• Model 3 has been parked in, or being driven in, extremely hot or cold temperatures.
• The sensors are affected by other electrical equipment or devices that generate ultrasonic waves.
• You are driving in a location where the sensors' ultrasonic waves are deflected away from the vehicle (such as driving next to a wall or pillar).
• The object is located too close to the bumper.
• A bumper is misaligned or damaged.
• An object that is mounted to Model 3 is interfering with and/or obstructing the sensor (such as a bike rack or bumper sticker).
• Model 3 rolls freely in the opposite direction of the gear you selected (for example, you will not receive an alert if Model 3 rolls backwards down a hill while in Drive).
