Most Tesla vehicles are equipped with advanced driver assist technology that enables Autopilot and Full Self-Driving capabilities. However, these systems may not always perform as expected.

In this article, we’ll explore the most common Autopilot alerts Tesla owners encounter and provide solutions to help you resolve them, ensuring a smooth and safe driving experience with your driver-assist features.

1. APP_w304 - Camera blocked or blinded. Clean camera or wait for it to regain visibility

This alert triggers when one or more of your Autopilot cameras cannot “see” the road properly. This can be caused by dirt or debris on the camera, sun glare, inclement weather, vehicle wraps, or other obstructions.

To resolve this alert, either wait for the sun glare and/or inclement weather to resolve or clean your cameras with water and a soft cloth. Ensure nothing is physically blocking the camera and test Autopilot again to ensure proper operation.

2. APP_w048 - Autopilot features temporarily unavailable. Features may be restored on next drive

This on-screen alert indicates that an issue has occurred, temporarily disabling your vehicle's Autopilot features.This alert can trigger for multiple reasons, including: blocked cameras, inclement weather, unclear road lines, etc.

In most cases, this alert will resolve on its own by your next drive. However, if it persists across multiple drives, you may need further diagnostics to detect an underlying issue.

3. APP_w207 - Autosteer temporarily unavailable

This alert is triggered when Autosteer becomes unavailable. Typically, this is due to one of several possible causes: missing or faded lane markers, narrow or winding roads, inclement weather, extremely hot or cold temperatures, or bright lines due to sun glare, other vehicle headlights, or other light sources.

Generally, this alert resolves on its own. If it persists across multiple drives, schedule an appointment for further diagnostics to assess possible causes.

4. DI_a175 - Cruise control unavailable

This alert will appear on screen when cruise control has become unavailable. In most cases, cruise control becomes unavailable due to the driver cancelling their request, the driver unbuckling their seat belt, a trunk or door being open, an environmental condition, or valet mode being active.

This alert will typically resolve once the blocking conditions are resolved. However, if none of these conditions are present and the alert persists during multiple drives, you may require diagnostics to determine the root cause of the alert.

5. APP_w389

This alert triggers when the front camera of your vehicle is obstructed by a hazy residue. When this happens, Autopilot cameras can no longer provide accurate information to the Autopilot computer.

To resolve this alert, inspect your windshield for dirt, debris, ice, snow, or other environmental obstructions. Additionally, check for wiper streaks that may be obstructing the camera.

Proceed to clean the windshield with water or windshield cleaner and a soft microfiber cloth to remove any debris. Once complete, test your vehicle to ensure the alert is resolved.

If the alert persists, or if you note that the haze is on the inside of the windshield, you may need service to disassemble the front camera and clean the windshield.

Conclusion

These five alerts are the most common Autopilot/Full Self-Driving alerts that trigger on Tesla vehicles. By knowing how to resolve them, you can often restore full Autopilot functionality yourself without needing a service visit.
