• 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 will
only change lanes when safe to do so.
• Require Lane Change Confirmation: 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.
Note: In addition to route-based and speed-
based lane changes, Navigate on Autopilot
also requests a lane change to the right as a
reminder to stay out of the left-most lane
when you are not passing other vehicles.
Note: The touchscreen displays route-based
lane changes at the top of the map's turn-by-
turn direction list to notify you that an
Autopilot
upcoming lane change is needed to stay on
the navigation route.
Operating Navigate on Autopilot
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 road. Touch this button to
allow Navigate on Autopilot to assist you on
your journey. When enabled, the Navigate on
Autopilot button is blue and the turn-by-turn
direction displays the Autosteer icon next to
maneuvers (such as freeway exits) that
Navigate on Autopilot will handle.
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 the Navigate on
Autopilot setting is turned on, Navigate on
Autopilot automatically becomes active when
you reach a supported controlled-access
portion of 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 freeway interchange
along your navigation route, the appropriate
turn signal engages and Autosteer maneuvers
Model S onto the off-ramp or interchange.
Warning: Never depend on Navigate on
Autopilot to determine an appropriate
Autosteer
