Tesla Autopilot Unavailable: Read the Alert Before Resetting

Start with the complete warning and any accompanying alerts. "Unavailable" can describe temporary visibility limits, calibration or a restriction on a particular feature. Those situations do not share one reset procedure.
Autosteer requires your hands on the wheel, attention to traffic and readiness to intervene. Feature availability varies with the vehicle, region, equipment and software. Check the manual on your touchscreen rather than assuming another Tesla has identical controls. Source: Tesla Model 3 — Autosteer.
Take control, then read the warning while parked
Continue controlling speed, steering and braking yourself when assistance is unavailable. If another warning tells you to stop, or you cannot control the vehicle safely, stop in a safe location and arrange help. An assistance warning alone is not enough information to pronounce the whole car safe.
Once parked, photograph the exact message and code. Record whether only one feature is unavailable and whether there are camera, braking, steering or power warnings alongside it. Do not dismiss those other alerts as part of an "Autopilot glitch."
Match the message to its next step
Examples from the Model 3 alert guide:
| Alert | What to check |
|---|---|
| APP_w207: Autosteer temporarily unavailable | Road/weather conditions can limit availability. If it persists into the next planned drive, check for obstruction or damage; arrange service if there is no obvious obstruction or damage is found. |
| APP_w222: Reduced front camera visibility | Inspect the front camera's windshield area while parked. Persistent alerts across subsequent drives without visible obstruction warrant service. |
| APP_w224: Cameras calibrating | Follow the calibration instructions and progress indicator for your vehicle. Unavailability after calibration completes warrants service. |
| APP_w304: Camera blocked or blinded | Check the indicated camera surfaces and follow cleaning/condensation guidance. If it persists through the next planned drive despite these steps, schedule service. |
These are distinct alerts, not diagnoses of a failed camera or computer. Read your exact entry in Tesla's Troubleshooting Alerts.
Check visibility without dismantling cameras
While parked, inspect accessible camera surfaces and the windshield area for dirt, ice or other obstruction. Use your model's camera-cleaning instructions: the current Model 3 manual specifies water and microfiber for camera lenses, and prohibits chemical or abrasive cleaners. Window-cleaning instructions are not permission to apply glass cleaner to an exposed camera lens. Source: Tesla — Cleaning a Camera.
Do not remove camera covers to wipe internal surfaces. If equipped, Controls > Service > Camera Visibility provides recent visibility information. Tesla also documents cabin preconditioning and defrosting for condensation affecting windshield/door-pillar camera visibility. Source: Tesla — Cameras.
If the rear image itself stays blurry, follow the separate rear-camera checks.
Reset calibration only when the procedure calls for it
Tesla describes calibration after certain service work or when a camera has moved from its calibrated position, such as applicable camera or windshield replacement. Clearing calibration starts that process again; it is not a general cure for unavailable assistance. Do not reset it merely to make a warning disappear. Follow the matched manual's conditions and service criteria instead of driving an arbitrary distance hoping to fix a fault. Source: Tesla — Drive to Calibrate Cameras.
Give service the evidence
Send the warning photo, event date/time, weather, location, software version and any recent windshield, camera or body work. Describe what persisted after the documented checks. Avoid repeatedly rebooting or clearing information before the concern is recorded.
If the actual problem is unexpected braking, use the phantom-braking guide. If the display is black or unresponsive, use the black-screen guide; that is a different problem from an unavailable feature on an otherwise functioning screen.
