What the Auto Start-Stop Light Means
On the your car, this 'A' symbol shows start-stop status. Green/available means it can stop the engine at rest; amber or crossed-out means conditions (battery charge, cabin temperature) are preventing it.
Common Causes
- Start-stop operating normally
- Weak or aging battery preventing stops
- High climate-control demand
- Battery sensor fault
- System switched off by the driver
How to Fix It
- Confirm whether start-stop was switched off
- Understand it disables when the battery is low or AC demand is high
- Have the battery and its sensor tested if it never works
- Replace an aged battery with the correct AGM/EFB type
- Scan for battery-management faults if needed
