Check the simple causes
- Park safely and confirm the vehicle is powered as required by the exact manual.
- Inspect the visible guide area for an object or folded material without reaching into the mechanism.
- Try one deliberate press rather than repeated rapid commands.
- Note whether the blind moves briefly, reverses, makes noise or remains silent.
Do not guess a reset sequence
Initialisation procedures can vary by version and software. Use only the ATTO 2 handbook procedure or instructions from an authorised BYD repairer.
Arrange inspection
Stop operating it if the blind is skewed, creased, trapped, noisy or repeatedly reverses. Record a short video and the vehicle software version for the retailer.
Step-by-step sunshade test
- Park, keep passengers and hands away from the blind and switch the vehicle to the manual-required power state.
- Remove loose objects only from the visible guide area without reaching into the mechanism.
- Press the normal control once and observe direction, distance moved, sound and any reversal.
- Try the opposite direction once only if the fabric is straight and no grinding is heard.
- Record a video and the complete vehicle-software version before stopping the test.
What the behaviour suggests
- Moves then reverses: resistance or anti-trap protection may be operating.
- Motor noise but no movement: stop; the drive or fabric may be jammed.
- Silent with other roof controls working: the switch, initialisation or individual mechanism needs checking.
- Skewed or creased fabric: do not operate it again.
Use only the initialisation procedure published for the exact model and version. Never pull the blind or defeat anti-trap protection.
