Tesla MODEL X 2019 Owner's Manual page 106

To set the cruising speed to the speed limit
plus any offset you've specified using Speed
Assist, pull the cruise control lever toward you.
If you are already driving faster than the speed
limit, the set speed does not adjust to the
speed limit—it adjusts to your current driving
speed. If you move the cruise control level up
or down after setting Traffic-Aware Cruise
Control to cruise at the speed limit, your set
speed becomes your current driving speed.
After setting the cruising speed, release the
accelerator pedal to allow Traffic-Aware Cruise
Control to maintain your set speed.
Note: Double-pulling the cruise control lever
toward you engages Autosteer (assuming it
has been enabled as described in
on page 110). In this case, if you are not
already cruising at a set speed, the cruising
speed is set to either your current driving
speed or the speed limit (plus any specified
offset), whichever is greater.
Warning: When you adjust the cruising
speed based on the speed limit, the set
speed does not change when the speed
limit changes. You must pull the cruise

control lever again to cruise at the new
speed limit. You can also manually adjust
your cruising speed at any time (see
Changing the Set Speed
Warning: Do not rely on Traffic-Aware
Cruise Control or Speed Assist to
determine an accurate or appropriate
cruising speed. Always cruise at a safe
speed based on road conditions and
applicable speed limits.
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
Distance on page 107), 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 Traffic-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.
Warning: Traffic-Aware Cruise Control
cannot detect all objects and, especially
in situations when you are driving over
80 km/h, may not brake/decelerate when
on page 106).
