Tesla Model Y: Steering Interventions

Lane Assist provides steering interventions if Model Y drifts into (or close to) an adjacent lane in which an object, such as a vehicle, is detected. In these situations, Model Y automatically steers to a safer position in the driving lane. This steering is applied only when Model Y is traveling between 30 and 85 mph (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

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

Lane Departure Avoidance operates when driving between 40 and 90 mph (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 steering wheel vibrates.
  • Assist: Corrective steering is applied to keep Model Y in a safe position if Model Y 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 Y 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 steering wheel. 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 Y gradually slows down to 15 mph (25 km/h) below the detected speed limit, or below the set cruising speed, and the hazard lights start flashing.

NOTE: Lane Departure Avoidance does not warn you of lane departures, or provide steering interventions, if the associated turn signal is on, which indicates an intentional lane change.

WARNING: Lane Departure Avoidance is intended to help keep you safe, but it does not work in every situation and does not replace the need to remain attentive and in control. WARNING: Keep your hands on the steering wheel and drive attentively at all times.

WARNING: Steering interventions are minimal and are not designed to move Model Y out of its driving lane. Do not rely on steering interventions to avoid side collisions.


     Emergency Lane Departure Avoidance

    Emergency Lane Departure Avoidance automatically applies steering to avoid a potential collision in situations where: Model Y is departing a lane and may collide with a vehicle traveling in the

     Limitations and Inaccuracies

    Lane Assist features cannot always detect lane markings and you may experience unnecessary or invalid warnings in these situations: Visibility is poor and lane markings are not clearly visible (

     Collision Avoidance Assist

    The following collision avoidance features are designed to increase the safety of you and your passengers: Forward Collision Warning - provides visual and audible warnings in situations when Mode


     How It Works

    Your Model Y includes the following components that actively monitor the surrounding area: A camera is mounted above the rear license plate. Ultrasonic sensors are located in the front and rear bumpers. A camera is mounted in each door pillar. Three cameras are mounted to the windshield abov


    Smart Summon is unlikely to operate as intended in the following types of situations: GPS data is unavailable due to poor cellular coverage. The driving path is sloped. Smart Summon is designed to operate on flat roads only (up to 10% grade). A raised concrete edge is detected. Depending on
