What the Auto Start-Stop Light Means
The auto start-stop light on a your car indicates the system that shuts the engine off at idle (to save fuel) is active or has just operated. An amber version can mean it is currently unavailable, often due to battery or climate demands.
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
