High-voltage battery fault warning light

What it means

The traction-battery fault light normally goes out after the power-on self-check. Remaining on, recurring or appearing during driving can indicate a monitored battery-system fault.

What to do

Contact a BYD authorised dealer or service provider for inspection as soon as possible for the described persistent or recurring conditions. Do not treat this as merely a low-charge reminder.
