AVAS fault warning light
What it means
This warning relates to the acoustic vehicle-alerting system used to alert nearby pedestrians at low speed, not an interior notification sound.
What to do
Do not rely on a faulty or disabled AVAS to alert pedestrians. If the expected prompt sound is absent, contact BYD. Consult this edition's AVAS chapter for its controlled checking procedure rather than attempting it in traffic.
