Auto Lane Change with Autopilot Tesla Model Y

When Autosteer is enabled on a vehicle with Auto Lane Change, you can use the turn signals to manoeuvre the Model Y into an adjacent lane without having to move the steering wheel (which would cancel Autosteer).

See Autopilot Overview and Features.

Warnings: It is the responsibility of the driver to assess if a lane change is safe and suitable. Always evaluate blind spots, lane markers, and the surrounding roads before making a lane change to ensure it is safe and suitable to proceed into the target lane.

  • Never rely on Auto Lane Change to choose the best driving path. Drive attentively by keeping an eye on the road and traffic ahead of you, scanning the environment around you, and checking the touchscreen for alerts.
  • Always be ready to act quickly if necessary.
  • Do not use Auto Lane Change on city streets or routes with frequently changing traffic conditions or when bicycles and pedestrians are present.
  • The capacity of the camera(s) to discern lane markers affects the operation of Auto Lane Change.
  • Auto Lane Change should not be used on winding highways with abrupt curves, icy or slippery roads, or when weather conditions (such as heavy rain, snow, fog, etc.) may obscure the view from the camera(s) or sensors.
  • Warning: Failure to heed all warnings and directions could result in property damage, serious injury, or death.

 

Operating Auto Lane Change

When Autosteer is turned on, Auto Lane Change is available. To use Auto Lane Change to change lanes, follow these steps:

  • Make visual checks to ensure that moving into the target lane is safe and suitable.
  • Make sure the proper turn signal is fully engaged.
  • When you've reached the target lane, turn off the turn signal.

If the following conditions are met, Auto Lane Change will move Model Y into the adjacent lane in the direction indicated by the turn signal:

  • The turn signal has been fully activated.
  • Up to the centre of the target lane, the ultrasonic sensors and Autopilot cameras do not identify a vehicle or object, and the lane markings indicate that a lane change is permissible.
  • The camera(s)' view is not hindered.
  • There is no other vehicle in your car's blind spot.
  • Auto Lane Shift can detect the target lane's outside lane marking halfway through the lane change.
  • Driving speed is about 30 mph (45 km/h)

Overtake Acceleration is enabled while the lane change is in progress, allowing Model Y to accelerate closer to the vehicle in front. Auto Lane Shift must identify the outside lane marking of the target lane halfway through the lane change. The lane change is aborted if this lane marking cannot be detected, and Model Y returns to its original driving lane.

Note that Auto Lane Change only moves the Model Y in one direction at a time. After you've completed the first lane change, you'll need to engage the turn signal a second time.

It is critical to keep an eye on the driving path in front of you as well as the surrounding region when utilising Auto Lane Change. Always be ready to take over steering if necessary. The tablet displays the lane marking as a dashed blue line as you cross into the neighbouring lane. Lane markers are presented as solid blue lines once you're in your new lane.

The touchscreen shows a series of cautions when Auto Lane Change is unable to operate at optimal performance or cannot operate owing to insufficient data.
As a result, when utilising Auto Lane Change, keep your eyes on the touchscreen and be ready to manually steer the Model Y.
