Parking brake system fault warning light
What it means
This brake-system warning is distinct from the EPB-applied status. The handbook associates it with low brake fluid or a braking-system fault and identifies simultaneous ABS warnings as significant.
What to do
Immediately park safely and contact BYD for low brake fluid, a persistent warning despite normal brake-fluid and EPB operation, or simultaneous brake and ABS fault warnings. The handbook warns that continuing with low brake fluid is dangerous.
