Parking brake system fault warning light
What it means
The parking/braking-system fault warning can indicate low brake fluid or a braking-system fault. It is distinct from the EPB engagement P indicator.
What to do
Immediately park safely and contact BYD for the described conditions: low brake fluid, persistent warning despite normal fluid and EPB operation, or simultaneous ABS warning. The handbook explicitly says not to continue driving with low brake fluid.
