What the Auto Start-Stop Light Means on a Ford B-Max
On the Ford B-Max, 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?
How worried should you be? For the Auto Start-Stop Light on a Ford B-Max, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Ford B-Max still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.

Frequently Asked Questions
Why is the Auto Start-Stop Light on in my Ford B-Max?
On a Ford B-Max, the Auto Start-Stop Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Auto Start-Stop Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Ford B-Max, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Auto Start-Stop Light on a Ford B-Max?
There is no single price for the Auto Start-Stop Light on a Ford B-Max; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Auto Start-Stop Light reset itself on a Ford B-Max?
Sometimes the Auto Start-Stop Light on a Ford B-Max clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
