The Autopilot cameras and ultrasonic sensors keep an eye on the markers in the lane you're driving in, as well as the areas around Model Y, for automobiles or other things.
Colored lines emanate from the image of your car on the touchscreen when an object is detected in your blind spot or close to the side of Model Y (such as a vehicle, guard rail, etc.). The lines' locations correspond to the detected object's location. The colour of the lines (white, yellow, orange, or red) indicates how close the object is to your car, with white being the furthest away and red being very close, demanding your urgent attention.
Only when travelling between 7 and 85 mph (12 and 140 km/h) do these coloured lines appear. If you're using Autosteer, these colourful lines will appear if you're going slower than 7 mph (12 km/h). When the Model Y is stopped (for example, in heavy traffic), the colourful lines do not appear.
Lane Assist will also alert you if a desired lane departure is not safe. When you activate the turn signal and a vehicle or object is identified in the adjacent lane you intend to enter, the touchscreen displays a red lane line to indicate that a vehicle or object has been detected. The lane line returns to normal when the vehicle or object is no longer detected.
Caution: Ensure that all cameras and sensors are in good working order. Autopilot performance can be harmed by dirty cameras and sensors, as well as weather conditions like rain and faded lane lines.
Warning: Lane Assist functions are simply for guidance and are not meant to take the place of your own direct visual assessments. Before changing lanes, use side mirrors to visually assess the lane you're entering and do the necessary shoulder checks.
Warning: Never rely on Lane Assist to warn you about driving outside of your lane unintentionally, or to warn you about a vehicle in your blind area or close to the side of your car. Lane Assist's performance might be hampered by a variety of external conditions, such as a lack of lane markers or curbs. This could lead to erroneous or non-existent warnings. It is the obligation of the driver to remain attentive, pay attention to the driving lane, and be aware of other road users at all times. Failure to comply can lead to serious harm or death.
Lane Assist also has these features to help with safety in the driving lanes:
This feature may or may not be available depending on your vehicle's configuration. When driving between 40 and 90 mph (64 and 145 km/h) on major highways with clearly visible lane markings, Lane Departure Avoidance gives steering interventions if the Model Y wanders into (or close to) an adjacent lane.
Press Controls > Autopilot > Lane Departure Avoidance from the drop-down menu and select one of the settings:
The setting is saved until changed manually.
The designated lane line is highlighted in blue on the touchscreen when Lane Departure Avoidance detects drifting and executes a steering intervention.
Note: Lane Departure Avoidance is designed to keep you safe, but it does not operate in every situation and does not take the place of staying alert and in control.
Warning: Always keep your hands on the steering wheel. Model Y emits a chime and the hazard warning lights flash if it detects your hands are not on the steering wheel.
Warning: The steering adjustments are minor and aren't intended to push the Model Y out of its lane. To avoid side crashes, don't rely on steering interventions.
This feature may or may not be available depending on your vehicle's configuration.
When going between 40 and 90 mph (64 and 145 km/h), Emergency Lane Departure Avoidance aims to avoid a potential collision with a vehicle in an adjacent lane by directing Model Y back into your driving lane. If the cameras detect the lane's edge, such as a lane line or kerb, this works. When you use this steering intervention, you'll hear a chime and the touchscreen will display a warning with the lane line highlighted in red until Model Y returns to the driving lane. Touch Controls > Autopilot > Emergency Lane Departure Avoidance to toggle it on or off.
Touch Controls > Autopilot > Blind Spot Collision Warning Chime if you want a chime to sound when a car enters your blind spot and a possible collision is detected.
Warning: Collision in the Blind Spot Chime isn't capable of detecting every collision. It is the obligation of the driver to stay aware and examine their blind zones.
This feature may not be accessible on your vehicle due to market area and vehicle configuration. When your car is travelling at a much quicker rate than the lanes around it, Model Y automatically slows down. This is particularly useful in congested areas or when vehicles are continually moving into new lanes. When Model Y senses that nearby driving speeds are much slower, the next lane is indicated with arrows on the touchscreen, and identified vehicles are highlighted grey, and your vehicle slows down accordingly. By tapping the accelerator pedal, you can temporarily disable this feature.
Lane Assist may not always be able to recognise lane markers clearly, and you may receive superfluous or invalid alerts as a result:
Due to severe rain, snow, fog, and other factors, visibility is poor and lane markers are difficult to see. The ultrasonic sensors' precise detection zone vary based on the environment.
In the following conditions, Lane Assist may not issue warnings or may issue alerts that are inappropriate:
In addition, in the following conditions, Lane Assist may not drive Model Y away from an adjacent car or may apply unnecessary or improper steering:
Warning: The scenarios listed above do not cover every scenario that could cause Lane Assist warnings to fail. For a variety of reasons, Lane Assist may not function as planned. Stay awake and pay attention to the road when driving to avoid a collision. This will allow you to foresee the need for remedial action as soon as feasible.
