Why is my Kia Ceed's start-stop system not working?

I recently purchased a Kia Ceed and noticed that the start-stop system is not functioning properly. When I come to a stop, the engine does not turn off and the start-stop indicator does not appear on the dashboard. What could be the issue and how can I fix it?

First, check if the start-stop system has been enabled in your vehicle's settings. If it has, then the issue could be with the battery. Make sure it is fully charged and in good condition.

Another possible cause could be a faulty sensor or solenoid in the start-stop system. I would recommend taking your Kia Ceed to a certified mechanic for a diagnostic check.

It is also worth checking if the air conditioning or defrost system is on when the start-stop system is not functioning. These systems can sometimes override the start-stop system to maintain comfort in the cabin.
