High-voltage battery low SOC warning light
What it means
This indicates low state of charge in the high-voltage traction battery, not a battery-system fault. The battery chapter notes that acceleration performance can decline at low charge. It does not give a universal percentage threshold for this warning light.
What to do
Arrange charging promptly and check the actual charge level, remaining range and instrument-panel messages. The handbook advises timely charging to maintain enough range. Do not assume a fixed reserve distance or interpret the symbol as permission to continue a journey regardless of the displayed conditions.
