Tesla Model 3: Auto Lane Change

When Autosteer is active on a vehicle equipped with Auto Lane Change, you can use the turn signals to move Model 3 into an adjacent lane without moving the steering wheel (which would cancel Autosteer).

Warning: It is the driver's responsibility to determine whether a lane change is safe and appropriate. Therefore, before initiating a lane change, always check blind spots, lane markings, and the surrounding roadway to confirm it is safe and appropriate to move into the target lane.

Warning: Never depend on Auto Lane Change to determine an appropriate driving path. Drive attentively by watching the road and traffic ahead of you, checking the surrounding area, and monitoring the touchscreen for warnings.

Always be prepared to take immediate action.

Warning: Do not use Auto Lane Change on city streets or on roads where traffic conditions are constantly changing and where bicycles and pedestrians are present.

Warning: The performance of Auto Lane Change depends on the ability of the camera(s) to recognize lane markings.

Warning: Do not use Auto Lane Change on winding roads with sharp curves, on icy or slippery roads, or when weather conditions (such as heavy rain, snow, fog, etc.) may be obstructing the view from the camera(s) or sensors.

Warning: Failure to follow all warnings and instructions can result in property damage, serious injury or death.

Operating Auto Lane Change

Auto Lane Change is available whenever Autosteer is active. To change lanes using Auto Lane Change:

1. Perform visual checks to make sure it is safe and appropriate to move into the target lane
2. Fully engage the appropriate turn signal.
3. Disengage the turn signal after you are in the target lane.

Auto Lane Change moves Model 3 into the adjacent lane in the direction indicated by the turn signal, provided the following conditions are met:

• The turn signal is fully engaged.
• The ultrasonic sensors and Autopilot cameras do not detect a vehicle or obstacle up to the center of the target lane.
• The lane markings indicate that a lane change is permitted.
•  The view of the camera(s) is not obstructed.
• Your vehicle does not detect another vehicle in its blind spot.
• Midway through the lane change, Auto Lane Change can detect the outside lane marking of the target lane.
• Driving speed is at least 30 mph (45 km/h).

As the lane change is in progress, Overtake Acceleration is activated, allowing Model 3 to accelerate closer to a vehicle in front. Midway through the lane change, Auto Lane Change must detect the target lane's outside lane marking. If this lane marking cannot be detected, the lane change is aborted and Model 3 returns to its original driving lane.

Note: Auto Lane Change moves Model 3 one lane at a time. Moving into an additional lane requires you to engage the turn signal a second time after the first lane change is complete.

When using Auto Lane Change, it is important to monitor its performance by watching the driving path in front of you and the surrounding area. Stay prepared to take over steering at any time. As you are crossing over into the adjacent lane, the touchscreen displays the lane marking as a dashed blue line. Once in your new lane, lane markings are displayed as solid blue lines again.

In situations where Auto Lane Change is unable to operate at optimal performance, or cannot operate due to inadequate data, the touchscreen displays a series of warnings.

Therefore, when using Auto Lane Change, always pay attention to the touchscreen and be prepared to manually steer Model 3.
