Airbag fault warning light
What it means
The restraint-system light normally extinguishes after the ignition-on self-check. A missing self-check, persistent light or warning appearing during driving can indicate a monitored airbag-system fault.
What to do
Contact a BYD authorised dealer or service provider for inspection as soon as possible in those conditions. Do not interpret this as the ordinary unfastened-seat-belt reminder.
