Low Speed Warning Sound System Fault Warning LightWarning

This warning light indicates a fault with the Low-Speed Pedestrian Warning System. Electric vehicles are required to emit an audible alert when travelling at low speeds (typically under 20 km/h) to warn pedestrians of the vehicle's approach. With this system faulty, your vehicle will run silently at low speeds, significantly increasing the risk of collision with pedestrians.

Can I drive?Yes — safe to drive
What to doContact a BYD authorised service centre to have the system inspected and repaired. Until the fault is rectified, exercise additional caution when driving at low speeds, especially in high-pedestrian areas such as car parks, residential streets, and school zones.
Low Speed Warning Sound OFF IndicatorInfo

This indicator means the low-speed pedestrian warning system has been manually switched off. Your EV normally emits a warning sound when travelling below 20km/h to alert pedestrians and cyclists, but this can be disabled through your vehicle settings. When off, your vehicle will run silently at low speeds. Please note that some Australian jurisdictions legally require this safety feature to remain active.

Can I drive?Yes — safe to drive
What to doThis light confirms the pedestrian warning sound is currently disabled. To reactivate it, go to your vehicle settings and turn the low-speed alert back on. We recommend keeping this feature enabled in school zones, car parks, and busy urban areas to help keep pedestrians safe.
