NOTE: Double-pulling the Autopilot stalk toward
you engages Autosteer (assuming it has been
enabled as described in Autosteer on page 102)
in addition to setting the cruising speed.
WARNING: When you adjust the cruising
speed based on the speed limit, the set
cruising speed may not change when the
speed limit changes.
WARNING: Do not rely on Trac-Aware Cruise
Control or Speed Assist to determine an
accurate or appropriate cruising speed. It is the
driver's responsibility to cruise at a safe speed
based on road conditions and applicable speed
limits.
3.
To change your speed while using Trac-Aware
Cruise Control, you can use the right scroll wheel or
the Autopilot stalk. For details, see Changing the
Cruising Speed on page 98.
4. To cancel Trac-Aware Cruise Control, push the
stalk away from you once or press the brake pedal.
See
Canceling and Resuming on page 100 for more
information.
Changing the Cruising Speed
To change the set cruising speed while using Trac-
Aware Cruise Control, move the Autopilot stalk up
(increase) or down (decrease) until the instrument
panel icon displays your desired cruising speed.
To increase/decrease speed by
1 mph (1 km/h), move
the stalk up or down to the first position and release. To
increase/decrease speed to the closest 5 mph (5 km/h)
increment, move the stalk up/down to the second
position and release. For example, if you are traveling at
57 mph and you move the stalk up to the second
position and release, the speed increases to 60 mph.
You can also increase/decrease speed by holding the
stalk in the full up/down position and releasing when
the icon on the instrument panel displays your desired
cruising speed.
You can also pull and hold the Autopilot stalk towards
you for approximately half a second to cruise at the
speed limit.
NOTE: It may take a few seconds for Model X to reach
the new cruising speed, assuming Model X is not
cruising behind a vehicle that is driving slower than
your set speed.
Cruising at the Set Speed
Trac-Aware Cruise Control maintains your set cruising
speed whenever a vehicle is not detected in front of
Model X. When cruising behind a detected vehicle,
Trac-Aware Cruise Control accelerates and
decelerates
Model X as needed to maintain a chosen
following distance (see Adjust the Following Distance
on page 99), up to the set speed.
Trac-Aware Cruise Control also adjusts the cruising
speed when entering and exiting curves.
You can manually accelerate at any time when cruising
at a set speed, but when you release the accelerator,
Trac-Aware Cruise Control resumes cruising at the set
speed.
NOTE: When Trac-Aware Cruise Control is actively
slowing down Model X to maintain the selected
distance from the vehicle ahead, brake lights turn on to
alert other road users that you are slowing down. You
may notice slight movement of the brake pedal.
However, when
Trac-Aware Cruise Control is
accelerating Model X, the accelerator pedal does not
move.
WARNING:
Trac-Aware Cruise Control may
occasionally cause Model X to brake when not
required or when you are not expecting it. This
can be caused by closely following a vehicle
ahead, detecting vehicles or objects in adjacent
lanes (especially on curves), etc.
WARNING:
Due to limitations inherent in the
onboard GPS (Global Positioning System), you
may experience situations in which Trac-Aware
Cruise Control slows down the vehicle, especially
near highway exits where a curve is detected
and/or you are actively navigating to a
destination and not following the route.
