Tesla Model S: Operating Autosteer

Before you can operate Autosteer, you must enable it by touching Controls > Autopilot > Autosteer (Beta).

To indicate that Autosteer is available (but not actively steering Model S), the instrument panel displays a gray Autosteer icon.

To initiate Autosteer, press the right scroll wheel.

NOTE: If the setting for Autosteer Activation is set to Single Click (touch Controls > Autopilot > Autosteer Activation), Autosteer engages when you single-press the right scroll wheel. If set to Double Click, you must double-press the right scroll wheel to engage Autosteer.

To indicate that Autosteer is now actively steering Model S, the instrument panel displays the Autosteer icon in blue. When Autosteer is able to detect lane markings, it also displays the driving lane in blue.

Autosteer briefly displays a message on the instrument panel reminding you to pay attention to the road and be ready to take over at any time.

The speed at which you can initiate Autosteer can vary depending on various conditions and whether or not a vehicle is detected ahead of you. When no vehicle is detected ahead of you, you must be driving at least 18 mph (30 km/h), unless certain vehicle and environmental conditions are met, in which case, you may be able to initiate it at lower speeds. When a vehicle is detected ahead of you, you can initiate Autosteer at any speed, even when stationary, provided Model S is at least 5 feet (150 cm) behind the detected vehicle.

NOTE: The maximum cruising speed is 90 mph (150 km/h). It is the driver's responsibility to cruise at a safe speed based on road conditions and speed limits.

NOTE: Auto High Beam is automatically enabled when Autosteer is engaged and the maximum cruising speed may be limited to a lower speed for vehicles manufactured after approximately February 13, 2022.

CAUTION: If available in your market region, Model S detects lights from an emergency vehicle when using Autosteer at night on a high speed road, the driving speed is automatically reduced and the instrument panel displays a message informing you of the slowdown. You will also hear a chime and see a reminder to keep your hands on the steering yoke. When the light detections pass by or cease to appear, Autopilot resumes your cruising speed. Alternatively, you may tap the accelerator to resume your cruising speed.

WARNING: Never depend on Autopilot features to determine the presence of emergency vehicles. Model S may not detect lights from emergency vehicles in all situations. Keep your eyes on your driving path and always be prepared to take immediate action.

In situations where Autosteer is temporarily unavailable, the Autosteer icon disappears. For example, your driving speed is not within the speed required for Autosteer to operate. Autosteer may also be unavailable if it is not receiving adequate data from the camera(s).

If unable to detect lane markings, Autosteer may determine the driving lane based on a vehicle you are following.

In most cases, Autosteer attempts to center Model S in the driving lane. However, there may be situations in which Autosteer may steer Model S in a driving path that is off set from the center of the lane (for example, detection of guard rails).

WARNING: Autosteer is not designed to, and will not, steer Model S around objects partially in a driving lane and in some cases, may not stop for objects that are completely blocking the driving lane. Always watch the road in front of you and stay prepared to take immediate action. It is the driver's responsibility to be in control of Model S at all times.

Restricted Speed

On a controlled-access highway, the cruising speed reflects the speed limit, taking into consideration any off set you've specified using Speed Assist. However, if you choose to use Autosteer on residential roads, a road without a center divider, or a road where access is not limited, Autosteer may limit the maximum allowed cruising speed and the instrument panel displays a message indicating that speed is restricted. The restricted speed will be the speed limit of the road plus 5 mph (10 km/h).

In situations where the speed limit cannot be detected when Autosteer is engaged, Autosteer reduces your driving speed and limits the set cruising speed to 45 mph (70 km/h). Although you can manually accelerate to exceed the limited speed, Model S may not brake for detected obstacles. Autosteer slows down to the limited speed when you release the accelerator pedal. When you leave the road, or disengage Autosteer by using the steering yoke, you can increase your set speed again, if desired.

Hold Steering Yoke

Autosteer determines how best to steer Model S. When active, Autosteer requires you to hold the steering yoke. If it does not detect your hands on the steering yoke for a period of time, a flashing light appears along the top of the instrument panel and the following message displays:

Apply slight turning force to steering yoke

Autosteer detects your hands by recognizing slight resistance as the steering yoke turns, or from you manually turning the steering yoke very lightly (without enough force to take over steering). Autosteer also qualifies your hands as being detected if you engage a turn signal or use a button or scroll wheel on the steering yoke.

NOTE: When your hands are detected, the message disappears and Autosteer resumes normal operation.

Autosteer requires that you pay attention to your surroundings and remain prepared to take control at any time. If Autosteer still does not detect your hands on the steering yoke, the flashing light on the instrument panel increases in frequency and a chime sounds.

If you repeatedly ignore Autosteer's prompts to apply slight force to the steering yoke, Autosteer disables for the rest of the drive and displays the following message requesting you to drive manually. If you don't resume manual steering, Autosteer sounds a continuous chime, turns on the warning flashers, and slows the vehicle to a complete stop.

Autosteer unavailable for the rest of this drive. Hold steering yoke to drive manually.

For the rest of the drive, you must steer manually. Autosteer is available again on your next drive (after you stop and shift Model S into Park).

Take Over Immediately

In situations where Autosteer is unable to steer Model S, Autosteer sounds a warning chime and displays the following message on the instrument panel:

Take over immediately

When you see this message, TAKE OVER STEERING IMMEDIATELY.

Canceling Autosteer

Autosteer cancels when:

  • You press the brake pedal
  • You start steering manually
  • You exceed the maximum speed at which Autosteer operates - 90 mph (150 km/h)
  • You shift
  • A door is opened
  • An Automatic Emergency Braking event occurs

When Autosteer cancels, it sounds a chime and the Autosteer icon either turns gray to indicate that Autosteer is no longer active, or disappears to indicate that it is not currently available.

NOTE: If Autosteer Activation is set to Double Click and Autosteer cancels because you started steering manually, Traffic-Aware Cruise Control remains active. If Autosteer Activation is set to Single Click and Autosteer cancels because you started steering manually, Traffic- Aware Cruise Control also cancels.

To disable Autosteer so it is no longer available, touch Controls > Autopilot > Autosteer (Beta).
