Battery / charging warning
Driver guidance · CAUTION — symbol color, meaning and urgency can differ by vehicle
What the symbol may mean
The charging system may not be supplying expected electrical power while the engine is running.
What to do now
Reduce nonessential electrical demand and pull over safely if other systems or lighting deteriorate. Arrange prompt charging-system diagnosis.
What a technician may check
Charging voltage, alternator belt and battery connections require checks.
Always follow the exact vehicle handbook; colored lamps and warning behavior vary across models. A serious vehicle fault should not be cleared or driven through without inspection.
