Applies to the official ATTO 3 (2024), English RHD, 20260304 handbook. Chinese domestic Yuan Plus (元PLUS) reports supplied the question; they do not verify an export-car defect, shared firmware or a repair. Match your car's handbook before using a control.

THE QUICK ANSWER

Check Settings → Vehicle → Exterior Rearview Mirror → Auto-fold, then use the physical fold button once to compare both mirrors. Do not repeatedly operate a frozen or obstructed mechanism.

China-market owner report

In a discussion dated 2025-05-06, the linked China-market report raised this issue: A 2024-purchased Yuan Plus owner reported one mirror intermittently failing to fold when locking. This is an individual account, not a confirmed diagnosis or failure-rate finding. The steps below use the export handbook.

Checks to make while safely parked

1Look for ice or obstructionInspect both housings without forcing them. If frozen, follow the handbook’s de-icer advice and let the mechanism free up before using the controller.
2Check automatic foldingOpen Exterior Rearview Mirror settings and inspect Auto-fold. A disabled automatic setting can explain both mirrors staying open when you lock the car.
3Compare the fold buttonPress the mirror fold button while stationary. Both mirrors should fold; another press requests their normal position. Note whether the same side fails each time.
4Restore visibility before drivingMake sure both mirrors are extended and correctly adjusted. If a mirror cannot provide a proper rearward view, arrange assistance before driving.

Tick steps as you go. Your progress stays in this tab.

Check the result and know when to stop

A single side that still stalls or makes unusual sounds warrants inspection rather than a guessed battery replacement or controller reset. Record a short video while parked showing the control used and the affected side. The owner report does not prove that low voltage or lubrication is the cause.

Common questions

Can the touchscreen setting fix a damaged motor?+

No. It only controls the automatic function; it does not repair a mechanical fault.

Should I force the housing open?+

Avoid forcing a stuck mechanism. Ask BYD how to restore it safely if normal control fails.
