Lane Assist provides steering interventions if Model X drifts into (or close to) an adjacent lane in which an object, such as a vehicle, is detected. In these situations, Model X automatically steers to a safer position in the driving lane. This steering is applied only when Model X is traveling between 48 and 140 km/h on major roads with clearly visible lane markings. When a steering intervention is applied, the instrument panel briefly displays a warning message.

Lane Departure Avoidance is designed to warn you if Model X is drifting out of, or nears the edge of, your driving lane.

Lane Departure Avoidance operates when driving between 64 and 145 km/h on roads with clearly visible lane markings. You can choose if and how you want Lane Departure Warning to operate by touching Controls > Autopilot > Lane Departure Avoidance and selecting between these options:

• Off: You are not warned of lane departures or potential collisions with a vehicle in an adjacent lane.
• Warning: If a front wheel passes over a lane marking, the vibrates.
• Assist: Corrective steering is applied to keep Model X in a safe position if Model X drifts into an adjacent lane or near the edge of the road.

When Lane Departure Avoidance is enabled and Traffic-Aware Cruise Control is active, if Model X drifts out of the driving lane when the associated turn signal is off, Lane Assist also checks to see whether your hands are on the . If hands are not detected, the instrument panel displays a series of alerts, similar to those that are used when driving with Autosteer. If hands are repeatedly not detected Model X gradually slows down to 25 km/h below the detected speed limit, or below the set cruising speed, and the hazard lights start flashing.

Emergency Lane Departure Avoidance automatically applies steering to avoid a potential collision in situations where:

• Model X is departing a lane and may collide with a vehicle traveling in the same direction in the adjacent lane (regardless of the status of the turn signal).
• Model X is departing a lane into an oncoming lane, the turn signal is off, and an oncoming vehicle is detected.
• Model X is departing the road and the turn signal is off (for example, very close to the edge of the road and a collision may occur).

To turn this feature on or off, touch Controls > Autopilot > Emergency Lane Departure Avoidance.

When Emergency Lane Departure Avoidance applies steering, a chime sounds and the instrument panel displays a warning and highlights the lane marking in red.

Emergency Lane Departure Avoidance operates when Model X is traveling between 64 and 145 km/h on a road with clearly visible lane markings, curbs, etc.

Lane Assist features cannot always detect lane markings and you may experience unnecessary or invalid warnings when:

• Visibility is poor and lane markings are not clearly visible (due to heavy rain, snow, fog, etc.).
• Bright light (such as from oncoming headlights or direct sunlight) is interfering with the view of the camera(s).
• A vehicle in front of Model X is blocking the view of the camera(s).
• The windshield is obstructing the view of the camera(s) (fogged over, dirty, covered by a sticker, 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).
• The road is narrow or winding.
• Objects or landscape features are casting strong shadows on lane markers.

Lane Assist may not provide warnings, or may apply inappropriate warnings, when:

• One or more of the sensors (if equipped), or cameras is damaged, dirty, or obstructed (by mud, ice, or snow, or by a vehicle bra, excessive paint, or adhesive products such as wraps, stickers, rubber coatings, etc.).
• Weather conditions (heavy rain, snow, fog, or extremely hot or cold temperatures) are interfering with sensor operation.
• The sensors (if equipped) are affected by other electrical equipment or devices that generate ultrasonic waves.
• An object that is mounted to Model X is interfering with and/or obstructing a sensor (such as a bike rack or a bumper sticker).

In addition, Lane Assist may not steer Model X away from an adjacent vehicle, or may apply unnecessary or inappropriate steering, in these situations:

• You are driving Model X on sharp corners or on a curve at a relatively high speed.
• Bright light (such as from oncoming headlights or direct sunlight) is interfering with the view of the camera(s).
• You are drifting into another lane but an object (such as a vehicle) is not present.
• A vehicle in another lane cuts in front of you or drifts into your driving lane.
• Model X is not traveling within the speeds at which the Lane Assist feature is designed to operate.
• One or more of the sensors (if equipped) 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 operation.
• The sensors (if equipped) 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).
