Low-voltage power system fault warning light

What it means

When this warning appears while moving, it indicates a problem with the low-voltage power system. It is distinct from low traction-battery charge.

What to do

Turn off devices such as air conditioning, fan and radio. Pull over immediately when safe and contact BYD for rescue as soon as possible. Do not dismiss it as a harmless low-charge reminder.
