Tesla Model 3: Adjacent Lane Speed
Due to market region and vehicle
configuration, this feature may not be
available on your vehicle.
When your vehicle is moving at a significantly
faster speed than neighboring lanes, Model 3
automatically reduces your driving speed. This
is especially helpful in heavy traffic situations
or when vehicles are constantly merging into
different lanes. When Model 3 detects that
neighboring driving speeds are significantly
slower, the neighboring lane is highlighted
with arrows and detected vehicles are
highlighted gray on the touchscreen, and your
vehicle slows down as appropriate. This
functionality can be temporarily overridden by
pressing the accelerator pedal. Never rely on
Autopilot to determine a safe driving speed;
you are responsible for the vehicle and
obeying traffic laws.
Limitations and Inaccuracies
Lane Assist cannot always clearly detect lane
markings and you may experience
unnecessary or invalid warnings in these
situations:
- Visibility is poor and lane markings are not
clearly visible (due to heavy rain, snow,
fog, etc.). The exact detection zone of the
ultrasonic sensors varies depending on
environmental conditions.
- Bright light (such as from oncoming
headlights or direct sunlight) is interfering
with the view of the camera(s).
- A vehicle in front of Model 3 is blocking
the view of the camera(s).
- The windshield is obstructing the view of
the camera(s) (fogged over, dirty, covered
by a sticker, etc.).
- Lane markings are excessively worn, have
visible previous markings, have been
adjusted due to road construction, or are
changing quickly (for example, lanes
branching off, crossing over, or merging).
- The road is narrow or winding.
- Objects or landscape features are casting
strong shadows on lane markers.
Lane Assist may not provide warnings, or may
apply inappropriate warnings, in these
situations:
- One or more of the ultrasonic sensors is
damaged, dirty, or obstructed (such as by
mud, ice, or snow).
- Weather conditions (heavy rain, snow, fog,
or extremely hot or cold temperatures)
are interfering with sensor operation.
- The sensors are affected by other
electrical equipment or devices that
generate ultrasonic waves.
- An object that is mounted to Model 3 is
interfering with and/or obstructing a
sensor (such as a bike rack or a bumper
sticker).
In addition, Lane Assist may not steer Model 3
away from an adjacent vehicle, or may apply
unnecessary or inappropriate steering, in
these situations:
- You are driving Model 3 on sharp corners
or on a curve at a relatively high speed.
- Bright light (such as from oncoming
headlights or direct sunlight) is interfering
with the view of the camera(s).
- You are drifting into another lane but an
object (such as a vehicle) is not present.
- A vehicle in another lane cuts in front of
you or drifts into your driving lane.
- Model 3 is traveling slower than 30 mph
(48 km/h) or faster than 90 mph (145
km/h).
- One or more of the ultrasonic sensors is
damaged, dirty, or obstructed (such as by
mud, ice, or snow).
- Weather conditions (heavy rain, snow, fog,
or extremely hot or cold temperatures)
are interfering with sensor operation.
- The sensors are affected by other
electrical equipment or devices that
generate ultrasonic waves.
- An object mounted to Model 3 (such as a
bike rack or a bumper sticker) is
interfering with or obstructing a sensor.
- Visibility is poor and lane markings are not
clearly visible (due to heavy rain, snow,
fog, etc.).
- Lane markings are excessively worn, have
visible previous markings, have been
adjusted due to road construction or are
changing quickly (for example, lanes
branching off, crossing over, or merging).
Warning: The lists above do not represent
every possible situation that may interfere
with Lane Assist warnings. Lane Assist
may not operate as intended for many
other reasons. To avoid a collision, stay
alert and always pay attention to the
roadway when driving so you can
anticipate the need to take corrective
action as early as possible.
