WARNING: Do not rely on Traffic-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.
2. To change your speed while using Traffic-Aware
Cruise Control, you can use the right scroll wheel or
the Autopilot stalk. For details, see
Cruising Speed on page
3. To cancel Traffic-Aware Cruise Control, push the stalk
away from you once or press the brake pedal. See
Canceling and Resuming on page 99
information.

If you want a chime to sound when you engage or
cancel Traffic-Aware Cruise Control, touch Controls >

NOTE: Model X must be in Park.
Changing the Cruising Speed
To change the set cruising speed while using Traffic-
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
detected 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
Traffic-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,
Traffic-Aware Cruise Control accelerates and decelerates
Model X as needed to maintain a chosen following
distance (see
Adjust the Following Distance on page
98), up to the set speed.
Traffic-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,
Traffic-Aware Cruise Control resumes cruising at the set
speed.
NOTE: When Traffic-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 Traffic-Aware Cruise Control is accelerating
Model X, the accelerator pedal does not move.
WARNING: Traffic-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 Model X slows
down, especially near exits or off-ramps where a
curve is detected and/or you are navigating to a
destination and not following the route.
