Three days ago I've got my KIA Ceed 1,6 CRDI Automatic equipped with cruise control which is placed on the
right side of the wheel. On the left side is audio control without
"mute" button. Is there any way to mute the audio system in control
Yours is different to mine, my Cee'd didn't come with cruise control and the indicators are on the right side of the wheel. The mute button is normally above the mode button but in this case this doesn't sound like the case. I do know if you press the power button on the stero it turns it off,. if you're listening to a CD this comes back on in the same place. I'm really not sure about this what does the manual say?
The manual describe two type of wheel controls, depends if your car is equipped with or without cruise control.. One of them (Type A -> like your's), without cruise control, has mute button on the right side of the wheel. Type B (my case) has audio control on the left side (without mute button) and on the right side only C/C controls.
Pressing the power button on/off seems to be the only solution for me
