Low Speed Warning Sound System Fault Warning Light
WarningBYD · Vehicle
What does this warning light mean?
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 do
Contact 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.
