How does 407 AC writing air conditioner work?

Hello, first of all, there is a 2007 model 407, there is a digital air conditioner, but AC is not written. How do I operate the air conditioner and fan?

Press clim to the trip computer. Say activate cooling is turned on.
Likewise, when it says disable, it sends the air coming from outside with a fan. Oktk is 2017-06-27 20:55:46

If AC is written on the screen when you turn the fan on, the air conditioner is turned off, only the fan is running, the other time the first time you start the air conditioner will be activated directly ...

When the air conditioner is turned on, it does not write on the ac.
