Parking system fault warning light
What it means
The red exclamation-in-a-circle is the brake-system fault warning, separate from the red parking-brake-applied P symbol. Low brake fluid, a persistent warning with normal EPB operation and simultaneous ABS/brake warnings are listed fault conditions.
What to do
For those conditions, park safely immediately and contact BYD. The handbook explicitly says continuing with low brake fluid is dangerous; do not dismiss simultaneous ABS and brake-system warnings as an ordinary parking-brake status.
