Airbag fault warning light
What it means
The airbag-system light normally goes out shortly after ignition. An absent or persistent startup indication or illumination while driving can indicate a monitored restraint-system fault.
What to do
Arrange BYD inspection as soon as possible for an abnormal self-check, a persistent warning or a driving-time warning. Do not interpret it as the ordinary seat-belt reminder.
