What the Auto Start-Stop Light Means on a Aston Martin Vantage
On the Aston Martin Vantage, 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.
How Urgent Is the Auto Start-Stop Light?
