What does an A with a circle around it and an exclamation mark mean on a durango?
The symbol is tied to the vehicle’s Auto Start-Stop system and generally signals that the feature is unavailable or there is a fault in the system.
On a Dodge Durango, the dashboard display sometimes shows an “A” inside a circle with an exclamation point. This combination acts as a warning regarding the automatic stop/start function that saves fuel by turning off the engine at idle and restarting it when you lift off the brake. The exact meaning can depend on the model year and trim, but the light almost always indicates one of two things: the Auto Start-Stop system isn’t available right now, or there’s a fault detected by the system. Below is a breakdown of common scenarios and what you should do.
What the symbol typically indicates
Common scenarios when you might see this light.
- The Auto Start-Stop system is currently unavailable due to conditions like low battery state-of-charge, engine temperature not being optimal, or a heavy electrical load (such as accessories running or high-demand climate control).
- A fault has been detected in the Auto Start-Stop system, triggering the warning light to require inspection or service.
- The feature has been manually disabled or overridden by driver settings in some trims, in which case the light may serve as a reminder rather than a fault indicator.
In short, the light signals that you should not rely on Auto Start-Stop at that moment, and you may need to check electrical systems or get a diagnostic check if the warning stays on.
What to do if you see it
Steps to take when the symbol appears on your Durango’s dash.
- Check the battery and electrical load: ensure the battery is in good health and that terminals are clean and tight. A weak battery can prevent the Auto Start-Stop system from functioning.
- With the engine running, see if the light persists after a short drive. If conditions improve (battery charge rises, engine reaches temperature, etc.), the light may turn off on its own.
- If the light stays on, or comes on while driving, plan a diagnostic check with a Dodge dealer or a qualified mechanic to identify a potential fault in the Auto Start-Stop system or related components.
- Consider any recent changes or loads (extensive use of electrical accessories, aftermarket devices) that could affect the system; removing or adjusting these may help.
Temporary conditions can cause the light to appear briefly, but a continuous illumination should be checked by a professional to prevent unexpected loss of fuel-saving capability or other electrical issues.
Why this matters for your Durango
The Auto Start-Stop system is designed to improve fuel economy and reduce emissions by idling the engine less. If the system is unavailable or faulty, you may notice the engine staying on at stops or not engaging when you expect it to. Addressing the underlying cause helps ensure you’re getting the intended efficiency benefits and avoids potential battery or electrical problems down the line.
Summary
The A-in-a-circle-with-exclamation mark on a Durango is a warning related to Auto Start-Stop. It usually means the feature is not available at the moment or there is a fault that requires inspection. Check the battery and electrical system, be mindful of driving conditions, and seek a diagnostic if the light remains illuminated.

What does the a with a circle and exclamation mark mean?
An "A" with a circle and exclamation mark on a car's dashboard indicates a problem with the auto start-stop system. This can be caused by a weak battery, a faulty brake sensor, or other system malfunctions. You can try troubleshooting by checking the battery, inspecting the brake pedal sensors, or consulting your owner's manual, as some systems may require a professional diagnosis or code reset.
Common causes
- Weak battery: A low battery charge is a frequent cause, as the system requires sufficient power to operate.
- Faulty brake sensor: The system relies on brake pedal sensors, and if they are not functioning correctly, it can trigger the warning light.
- System sensor faults: Other sensor or module malfunctions can also disable the start-stop system.
What to do
- Check your owner's manual: Consult the manual for the specific meaning of the light on your vehicle and any recommended checks.
- Inspect the battery: Check the battery's health and ensure all connections are secure.
- Examine the brake pedal sensor: Ensure the brake pedal sensor is working properly and is not damaged.
- Consider a system reset: Sometimes, turning the vehicle off and on can reset the system. If the warning persists, an OBD-II scanner may be needed to clear the error code, but this should be done after the underlying issue is resolved.
- Seek professional help: If the light continues to appear after these checks, it's best to have a mechanic diagnose the issue to ensure proper function and safety.
