Navigate on Autopilot
WARNING: Never depend on Navigate on
Autopilot to determine an appropriate lane at an
off-ramp. Stay alert and perform visual checks to
ensure that the driving lane is safe and
appropriate.
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 back 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 X).
WARNING: When Navigate on Autopilot
deactivates, Autosteer remains active. Always be
prepared to take appropriate action.
WARNING: Navigate on Autopilot may not always
attempt to exit at an off-ramp or change lanes,
even when an exit or lane change is determined by
the navigation route. Always remain alert and be
prepared to manually steer onto an off-ramp, or
make a lane change to prepare for, or to exit at, an
off-ramp or interchange.
You can cancel Navigate on Autopilot at any time by
touching Navigate on Autopilot on the map's turn-by-
turn direction list (Model X reverts back to Autosteer), or
by canceling Autosteer entirely (see
Autosteer on page 108).
Lane Changes
Navigate on Autopilot changes lanes to either prepare
Model X for an upcoming off-ramp, to increase your
driving speed (not to exceed your set cruising speed), or
to move Model X out of a passing lane when you are not
actively passing other road users. A message displays at
the top of the map's turn-by-turn direction list to notify
you when an upcoming lane change is required to stay
on your navigation route. The instrument panel displays
the upcoming driving path:
When the instrument panel displays a message asking
you to confirm the lane change, engage the appropriate
turn signalor pull the Autopilot stalk toward you. If you
do not confirm the lane change within three seconds, a
chime sounds to remind you that Navigate on Autopilot
requires your confirmation to change lanes.
112
NOTE: 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.
Be Ready to Assist
When attempting to change lanes or maneuver Model X,
or when approaching construction zones, Navigate on
Autopilot may be unable to determine the appropriate
driving lane (for example, complex clover leafs and
multi-lane off-ramps) and the instrument panel displays
an alert indicating that Navigate on Autopilot is trying to
maneuver and may require assistance. When you see the
message, be prepared to take immediate action to
ensure that it is safe and appropriate to complete the
lane change or maneuver.
Canceling
WARNING: Navigate on Autopilot may not always
attempt to exit at an off-ramp or change lanes,
even when an exit or lane change is determined by
the navigation route. Always remain alert and be
prepared to manually steer onto an off-ramp, or
make a lane change to prepare for, or to exit at, an
off-ramp or interchange.
