Chime
If you want a chime to sound when you engage or
cancel Traffic-Aware Cruise Control, touch Controls >
Autopilot > Traffic-Aware Cruise Control Chime.
NOTE: Model Y must be in Park.
Changing the Cruising Speed
Roll the right scroll wheel up to increase, or down to
decrease, the set speed. Slowly rolling the scroll wheel
changes the set speed in 1 km/h increments and quickly
rolling the scroll wheel changes the set speed to the
closest 5 km/h increment.
With Traffic-Aware Cruise Control engaged and cruising
at a set speed, you can also change the cruising speed
to the current speed limit (including any offset you've
specified), by either pushing the drive stalk downward
and briefly holding, or touching and briefly holding the
speed limit sign on the touchscreen, until you see the
cruising speed change.
NOTE: It may take a few seconds for Model Y to reach
the new cruising speed, assuming Model Y 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 Y. When cruising behind a detected vehicle,
Traffic-Aware Cruise Control accelerates and decelerates
Model Y as needed to maintain a chosen following
distance (see Adjust the Following Distance on page
92), 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 Y 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
Y, the accelerator pedal does not move.
WARNING: Traffic-Aware Cruise Control may
occasionally cause Model Y 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 Y 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.
WARNING: Traffic-Aware Cruise Control may not
detect all objects and, especially when cruising
over 80 km/h, may not brake/decelerate when a
vehicle or object is only partially in the driving lane
or when a vehicle you are following moves out of
your driving path and a stationary or slow-moving
vehicle or object is in front of you. Always pay
attention to the road ahead and stay prepared to
take immediate corrective action. Depending on
Traffic-Aware Cruise Control to avoid a collision
can result in serious injury or death. In addition,
Traffic-Aware Cruise Control may react to vehicles
or objects that either do not exist, or are not in
your lane of travel, causing Model Y to slow down
unnecessarily or inappropriately.
