To enable Navigate on Autopilot, touch Controls > Autopilot > Autopilot Features > Autosteer > 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 or not you want 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. Route-based lane changes are designed to keep you on your navigation route (for example, moving you into an adjacent lane to prepare for an upcoming off-ramp) whereas speed-based lane changes are designed to maintain a driving speed (not to exceed your cruising speed) that allows you to minimize the time it takes to reach your destination (for example, moving into an adjacent lane to pass a vehicle in front of you). Speed-based lanes changes are optional. You can use this setting to disable speed-based lane changes or to specify how aggressively you want Navigate on Autopilot to change lanes to achieve the set cruising speed. The Mild setting is more conservative about lane changes and may result in a slightly longer driving time whereas Mad Max is designed to allow you to reach your destination in the shortest driving time possible, but changes lanes only when safe to do so.
• Exit Passing Lane: Choose whether you want Navigate on Autopilot to maneuver out of a passing lane when navigating to a destination.
  Note

  In addition to route-based and speed-based lane changes, Navigate on Autopilot requests a lane change out of a passing lane as a reminder to stay in a slower lane when you are not passing other vehicles. Choose NO to disable this and keep Model S in a passing lane except when needed to stay on the navigation route.
• Require Lane Change Confirmation (if equipped): By default, Navigate on Autopilot requires your confirmation before proceeding with a lane change by pulling the Autopilot stalk toward you or engaging the appropriate turn signal. However, if you want Navigate on Autopilot to change lanes without requiring this confirmation, turn this setting off. When you turn the setting off, you can specify if or how you want to be notified of lane changes (Off, Chime, Vibrate, or Both).
  Warning

  If you turn off Require Lane Change Confirmation, Navigate on Autopilot notifies you of upcoming lane changes and off-ramps, but it remains your responsibility to monitor the environment and maintain control of Model S at all times. Lane changes can occur quickly and suddenly. Always keep your hands on the wheel and your eyes on the driving path in front of you.

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. When enabled, the Navigate on Autopilot button is blue and the turn-by-turn direction displays the Autosteer icon next to the maneuvers (such as off-ramps) that Navigate on Autopilot will handle.

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. If Enable At Start Of Every Trip is turned off, you must touch the Navigate on Autopilot button to enable it for each navigation route.

Navigate on Autopilot activates and deactivates as appropriate, based on the type of road you are driving on. For example, if Autosteer is active and Navigate on Autopilot is enabled, Navigate on Autopilot automatically becomes active when you reach a controlled-access highway on your navigation route.

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

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 (for example, you take an exit or you enter a section of the navigation route that is no longer supported), Navigate on Autopilot reverts to Autosteer— a chime sounds and the instrument panel displays the driving lane lines in blue (instead of the single blue in front of Model S).

You can cancel Navigate on Autopilot at any time by touching Navigate on Autopilot on the map’s turn-by-turn direction list (Model S reverts to Autosteer), or by canceling Autosteer entirely (see Canceling Autosteer).
