Lane Assist • The sensors are affected by other electrical equipment or devices that generate ultrasonic waves. • An object mounted to Model X (such as a bike rack or a bumper sticker) is interfering with or obstructing a sensor. • Visibility is poor and lane markings are not clearly visible (due to heavy rain, snow, fog, etc.). • Lane markings are excessively worn, have visible previous markings, have been adjusted due to road construction or are changing quickly (for example, lanes branching off, crossing over, or merging). Warning: The lists above do not represent every possible situation that may interfere with Lane Assist warnings. Lane Assist may not operate as intended for many other reasons. To avoid a collision, stay alert and always pay attention to the roadway when driving so you can anticipate the need to take corrective action as early as possible. Autopilot 123
