Tesla Model 3: Drive to Calibrate Cameras

Model 3 must maneuver with a great deal of precision when Autopilot features are being used. Therefore, before some features (for example, Traffic-Aware Cruise Control or Autosteer) can be used for the first time or after certain Service repairs, the cameras must complete a self-calibration process. For your convenience, a progress indicator is displayed on the touchscreen.

Calibration typically completes after driving 20-25 miles (32-40 km), but the distance varies depending on road and environmental conditions. Driving on a straight road with highly-visible lane lines allows Model 3 to calibrate quicker. When calibration is complete, the Autopilot features are available for use. Contact Tesla only if your Model 3 has not completed the calibration process after driving 100 miles (160 km).

Note: If you attempt to use a feature that is not available until the calibration process is complete, the feature will not be enabled and the touchscreen displays a message.

Note: Model 3 must repeat the calibration process if the cameras are serviced by Tesla, and in some cases, after a software update.

Limitations

Many factors can impact the performance of Autopilot components, causing them to be unable to function as intended. These include (but are not limited to):

• Poor visibility (due to heavy rain, snow, fog, etc.).
• Bright light (due to oncoming headlights, direct sunlight, etc.).
• Damage or obstructions caused by mud, ice, snow, etc.
•  Interference or obstruction by object(s) mounted onto the vehicle (such as a bike rack).
• Obstruction caused by applying excessive paint or adhesive products (such as wraps, stickers, rubber coating, etc.) onto the vehicle.
• Narrow or winding roads.
• A damaged or misaligned bumper.
• Interference from other equipment that generates ultrasonic waves.
• Extremely hot or cold temperatures.

Warning: The list above does not represent an exhaustive list of situations that may interfere with proper operation of Autopilot components. Never depend on these components to keep you safe. It is the driver's responsibility to stay alert, drive safely, and be in control of the vehicle at all times.

Caution: If a windshield replacement is needed, take your vehicle to Tesla Service.

This will ensure appropriate handling and mounting of the camera(s). Failure to do so can cause one or more Autopilot features to malfunction.

Cleaning Cameras and Sensors

To ensure the various Autopilot components can provide information that is as accurate as possible, keep them clean and free of obstructions or damage. Occasionally remove any buildup of dirt by wiping the components with a soft cloth dampened with warm water.

Caution: Do not use chemical-based or abrasive cleaners. Doing so can damage surfaces.

Caution: Avoid using a high-pressure power washer.

Caution: Do not clean an ultrasonic sensor or camera lens with a sharp or abrasive object that can scratch or damage its surface.
