Traffic-Aware Cruise Control is always enabled.

To use Traffic-Aware Cruise Control:

1. To change the set speed, roll the right scroll wheel up to increase, or down to decrease. You can apply the accelerator at any time to temporarily override the set cruising speed. For more information, see While Using Autopilot.
2. To cancel Traffic-Aware Cruise Control, or press the brake pedal. For more information, see Canceling Autopilot.

When Traffic-Aware Cruise Control is available but not engaged, the instrument cluster displays the cruising speed in gray. The number shown represents the speed that will be set when you engage Traffic-Aware Cruise Control.

When Traffic-Aware Cruise Control is actively cruising at a set speed, the speed is highlighted with blue text.

If you engage a turn signal while Autosteer is active, Model X moves into the adjacent lane in the direction indicated by the turn signal, provided the following conditions are met:

• The turn signal is engaged.
• Lane markings indicate that a lane change is permitted.
• Auto Lane Change detected your hands on the steering wheel.
• Midway through the lane change, Model X must detect the target lane's outside lane marking. If this lane marking is not detected, the lane change is aborted and Model X returns to its original driving lane.
• The view of the camera(s) is not obstructed.
• Model X does not detect a vehicle in its blind spot, or a vehicle or obstacle up to the center of the target lane. If a vehicle or other obstacle is detected in the target lane, it is shown in red in the visualization on the instrument cluster and Model X does not complete the lane change until it is safe to do so.

The minimum speed at which Autopilot changes lanes may vary depending on region, adjacent lane speeds, and other factors. Always be ready to manually steer and change lanes as necessary. When an automatic lane change is in progress, Overtake Acceleration is activated, allowing Model X to accelerate closer to a vehicle in front (see Overtake Acceleration).

When you engage a turn signal, Autopilot moves Model X 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.

As Model X changes lanes, 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 instrument cluster displays the location in the lane that Model X is moving into.

Traffic-Aware Cruise Control cancels when:

• You press the brake pedal.
• You exceed 140 km/h.
• You shift into Reverse, Park, or Neutral.
• A door is opened.
• An Automatic Emergency Braking event occurs (see Collision Avoidance Assist).
• The driver's seatbelt is released, and/or the driver gets out of their seat.

When Traffic-Aware Cruise Control cancels, the cruising speed icon on the instrument cluster turns gray to indicate that Traffic-Aware Cruise Control is no longer active.

When Traffic-Aware Cruise Control cancels, Model X does not coast. Instead, regenerative braking slows down Model X in the same way as when you move your foot off the accelerator when driving without Traffic-Aware Cruise Control (see Regenerative Braking).

When Traffic-Aware Cruise Control is active and Autopilot is maintaining a set speed, the speed is highlighted with blue text on the instrument cluster.

When Autosteer is active, the steering wheel icon is blue and the lane markings are highlighted in blue on the visualization.

To display more details about the roadway and its surroundings, such as road markings, stop lights, and objects (such as trash cans and poles), touch Controls > Autopilot > Full Self-Driving Visualization Preview.

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 X in the driving lane. However, there may be situations in which Autosteer follows a driving path that is offset from the center of the lane (for example, if guard rails are detected).

Stopping and Slowdowns

When moving significantly faster than vehicles in adjacent lanes, Model X automatically reduces the driving speed. This is especially helpful in heavy traffic situations or when vehicles are constantly merging into different lanes. When Model X detects other vehicles driving significantly slower, the instrument cluster highlights the adjacent lanes with arrows and detected vehicles in gray, and Model X reduces the driving speed as appropriate. To temporarily override this feature, press the accelerator pedal.

When following a vehicle, Autopilot remains active at low speeds, even when Model X comes to a full stop. For example, Autopilot remains active even if Model X slows down to a complete or near-complete stop in heavy, stop-and-go traffic on a highway. When traffic starts moving more rapidly, Autopilot again accelerates up to the set speed.

Sometimes when Model X is at a full stop, Autopilot goes into a HOLD state. If this happens, briefly press the accelerator pedal to resume cruising.

When the HOLD status is active, the instrument cluster displays the HOLD icon and a message that indicates that you need to resume cruise control.

Model X goes into HOLD state while Autopilot is active in the following circumstances:

• Model X has been at a standstill for 5 minutes.
• Model X detects a pedestrian (the HOLD state may clear when the pedestrian is no longer detected).
• Model X suddenly loses visibility of the vehicle in front of you.
• An obstacle is detected in front of Model X.

In situations where Autopilot is unable to steer Model X, a warning chime sounds and the instrument cluster displays the following message.

Autosteer is aborting

When you see this message, take over steering immediately.

Autosteer determines how best to steer Model X. When active, Autosteer requires you to hold the steering wheel. If it does not detect your hands on the steering wheel for a period of time, a flashing blue light appears at the top of the vehicle status section of the instrument cluster and the following message displays:

Apply slight turning force to steering wheel

When your hands are detected, the message disappears and Autosteer resumes normal operation. Autosteer detects your hands by recognizing slight resistance as the steering wheel turns, or from you manually turning the steering wheel 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 wheel.

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 wheel, the flashing light on the vehicle status section of the instrument cluster increases in frequency and a chime sounds.

If you repeatedly ignore Autosteer's prompts to apply slight force to the steering wheel, Autosteer disables for the rest of the drive and displays the following message requesting you to drive manually.

Autopilot unavailable for current drive. Autopilot Strikeout - Attention warnings ignored.

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

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.

Use of Autopilot features will be suspended if improper usage is detected.

Use of Autosteer is suspended for a week when you or another driver of your vehicle receives three Autopilot "strikeouts." A strikeout is when the Autopilot system disengages for the remainder of a trip after the driver receives several audio and visual warnings for inattentiveness.

You can see how many strikeouts are remaining before Autopilot access is suspended by touching Controls > Autopilot.

A strikeout is forgiven after 7 days, as long as you don't receive another strikeout in that time.

There may be occasions where driver intervention is required and you must take over immediately to maintain safe driving. Driver-initiated disengagements do not count as improper usage and are expected from the driver.
