Hello guys, what is this sign?

Hello friends, I'm new to the forum, I bought a Peugeot 206 1.4 XT automatic as the first vehicle, I am very pleased, thank God, but today a malfunction light came on, when I started the vehicle, it goes away. If you can help, I would appreciate it in advance

I couldn't add an image, how to add
