Traffic-Aware Cruise Control is always enabled.

To use Traffic-Aware Cruise Control:

1. Press the right scroll button, then release the accelerator pedal to allow Traffic-Aware Cruise Control to maintain the cruising speed. A chime sounds to indicate that Traffic-Aware Cruise Control is now active.
   Note

   If Autopilot Activation is set to Single Click, pressing the right scroll button once also activates Autosteer (which includes Traffic-Aware Cruise Control). Touch Controls > Autopilot > Autopilot Activation and choose Double Click to use Traffic-Aware Cruise Control independently of Autosteer when you single-press the right scroll button.
2. 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.
3. To cancel Traffic-Aware Cruise Control, press the right scroll button 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.

To enable Autosteer:

1. Touch Controls > Autopilot > Autopilot Features > Autosteer (Beta).
2. After carefully reading and understanding the popup window, touch Yes.

When you engage Autosteer, Model S confirms activation with an audible chime and briefly displays a message on the instrument cluster reminding you to pay attention to the road and have your hands on the steering yoke (or steering wheel).

To indicate that Autosteer is available (but not actively steering Model S), the instrument panel displays a gray Autosteer icon. In situations where Autosteer is temporarily unavailable, the Autosteer icon disappears. (For example, if your driving speed is not within the speed required for Autosteer to operate.)

To indicate that Autosteer is active, the instrument cluster displays the Autosteer icon in blue.

When Autosteer is able to detect lane markings, it displays the edges of the driving lane in blue on the instrument cluster.

Whenever Autosteer is active, Traffic-Aware Cruise Control is active as well.

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 70 km/h. Although you can manually accelerate to exceed the limited speed, Model S will not brake for detected obstacles as long as you are applying the accelerator pedal. 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 (or steering wheel), you can increase your set speed again, if desired.

If you engage a turn signal while Autosteer is active, Model S 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 yoke (or steering wheel).
• Midway through the lane change, Model S must detect the target lane's outside lane marking. If this lane marking is not detected, the lane change is aborted and Model S returns to its original driving lane.
• The view of the camera(s) is not obstructed.
• Model S 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 S 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 S to accelerate closer to a vehicle in front (see Overtake Acceleration).

When you engage a turn signal, Autopilot moves Model S 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 S 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 S is moving into.

To enable Navigate on Autopilot, touch Controls > Autopilot > Navigate on Autopilot (Beta). Then, to customize how you want Navigate on Autopilot to operate, touch Customize Navigate on Autopilot:

• Enable at Start of Every Trip: Choose whether to automatically enable Navigate on Autopilot for every navigation route. When enabled, the Navigate on Autopilot button on the turn-by-turn direction list is already enabled at the start of every trip.
• Speed Based Lane Changes: Navigate on Autopilot is designed to perform both route-based and speed-based lane changes. Speed-based lanes changes are optional. You can use this setting to disable speed-based lane changes or to specify how assertively you want Navigate on Autopilot to change lanes to achieve the set cruising speed (Mild, Average, or Mad Max).
• Require Lane Change Confirmation: (if equipped) By default, Navigate on Autopilot requires your confirmation before proceeding with a lane change by pressing the appropriate turn signal. If you do not confirm the lane change within 3 seconds, a chime sounds to remind you that Navigate on Autopilot requires your confirmation to change lanes.
• Lane Change Notification: You can specify if or how you want to be notified of lane changes (Off, Chime, Vibrate, or Both).

If Enable at Start of Every Trip is turned on, Navigate on Autopilot engages automatically when:

• Autosteer is active.
• You are navigating to a destination.
• You are on a controlled-access highway.

Once enabled, the Navigate on Autopilot button appears on the map’s turn-by-turn direction list whenever a navigation route is active and the route includes at least one controlled-access highway.

If Enable at Start of Every Trip is turned off, touch the Navigate on Autopilot button above the turn-by-turn directions to enable it. Once the Navigate on Autopilot is selected, it will engage whenever you engage Autosteer.

The Navigate on Autopilot icon shows in the turn-by-turn direction list when you are navigating to a destination and Navigate on Autopilot is available but not active.

If Navigate on Autopilot is active, the icon is blue. If Enable at Start of Every Trip is turned on, the Navigate on Autopilot icon is selected whenever you start navigation. Touch the icon to cancel Navigate on Autopilot and revert to Autosteer.

Whenever Navigate on Autopilot is active, the Navigate on Autopilot button is blue and the instrument cluster displays the driving lane as a single blue line in front of Model S:

The turn-by-turn directions display the Autosteer icon next to the maneuvers (such as off-ramps) that Navigate on Autopilot will handle.

When Navigate on Autopilot is engaged Model Sautomatically makes both speed-based and route-based lane changes.

• Speed Based Lane Changes: Navigate on Autopilot changes lanes to reduce driving time to your destination. For example, if Model S is behind a vehicle going below the set cruising speed, Navigate on Autopilot will move into the passing lane to pass it. Speed-based lanes changes are optional.
• Route Based Lane Changes: Navigate on Autopilot changes lanes to route you to your destination. For example, Navigate on Autopilot will move into the exit lane as Model S approaches the off-ramp specified by the navigation route.

If you ignore a route-based lane change suggestion (for example, you are driving in the left lane while approaching an off-ramp on the right side of the highway), Navigate on Autopilot is unable to maneuver onto the off-ramp and as a result, you are re-routed to your destination.

Navigate on Autopilot activates and deactivates based on the type of road you are driving on. When Navigate on Autopilot is active and you approach an off-ramp or interchange along your navigation route, the appropriate turn signal engages and Autosteer maneuvers Model S onto the off-ramp or interchange.

When you leave a controlled-access highway Navigate on Autopilot reverts to Autosteer—a chime sounds and the instrument cluster displays the driving lane lines in blue (instead of the single blue in front of Model S). When Navigate on Autopilot deactivates, Autosteer remains active. Always be prepared to take appropriate action.

Traffic-Aware Cruise Control cancels when:

• You press the right scroll button on the steering yoke (or steering wheel).
• You press the brake pedal.
• You exceed 150 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 Autosteer cancels, a chime sounds 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.

When Navigate on Autopilot cancels but Autosteer remains active, a chime sounds and the visualization goes from a single blue line in the driving lane to two blue lines on either side of the lane.

When Traffic-Aware Cruise Control or Autosteer cancels, Model S does not coast. Instead, regenerative braking slows down Model S 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 yoke (or steering wheel) icon is blue and the lane markings are highlighted in blue on the visualization. If Navigate on Autopilot is also active, the Navigate on Autopilot button is blue and the instrument cluster displays the driving lane as a single blue line in front of Model S.

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 S 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).

Changing the Set Speed

Roll the right scroll wheel up to increase, or down to decrease, the set speed.

It may take a few seconds for Model S to reach the new cruising speed.

Stopping and Slowdowns

When moving significantly faster than vehicles in adjacent lanes, Model S automatically reduces the driving speed. This is especially helpful in heavy traffic situations or when vehicles are constantly merging into different lanes. When Model S detects other vehicles driving significantly slower, the instrument cluster highlights the adjacent lanes with arrows and detected vehicles in gray, and Model S 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 S comes to a full stop. For example, Autopilot remains active even if Model S 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 S 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 S goes into HOLD state while Autopilot is active in the following circumstances:

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

If available in your market region, Model S automatically reduces driving speed when lights from an emergency vehicle are detected when using Autosteer at night on a high speed road. When this happens, the instrument cluster 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 (or steering wheel). 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.

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

Autosteer determines how best to steer Model S. 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:

Steering yoke alert:

Apply slight turning force to steering yoke

Steering wheel alert:

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 S 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 five 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.
