Low-voltage power system fault warning light

What it means

This monitors the DC module and low-voltage-battery system. During charging it indicates a charging-system failure; while moving it indicates a DC or low-voltage-system problem.

What to do

If it illuminates while moving, turn off the air conditioning and fans, immediately park safely and contact a BYD authorised dealer or service provider. Do not infer that charging a 12V battery will clear the underlying fault.
