Controls with openpilot nightly-dev
- Steering
- openpilot helps keep you centered in your lane.
- Gas and brakes
- Factory adaptive cruise by default in the checked development build.
- Your role
- Watch the road and stay ready to steer or brake.
Check Software → Additional Vehicle Information → Autopilot computer: this entry is for HW2.5. A 2019 Model 3 can instead have HW3.
The car needs the newer 3-bit steering-message firmware, introduced for HW2.5 around Tesla software 2026.8.6. Older firmware leaves openpilot in dashcam mode. A version number alone is not the runtime check.
Optional alpha software speed control and radar wiring need the Tesla-specific setup instructions.
