cdk?

I'm looking into buying a used 2003 evo VIII and while doing research i found out that the car has a automatic and/ or manuel spray device to cool the intercooler. I was wondering where is this button located? I found a button to the left of the steering wheel that has a picture of the front tires turned and it says cdk on it i believe. What does this mean and what does it do? Thanks

the intercooler sprayer is on the center console by the cup holders. i'm not sure exactly what the other button is.

i think the spray is just to cool the intercooler more. hence "intercooler". Mitsubishi did away with it because it was useless on the 05's

i think the spray is just to cool the intercooler more. hence "intercooler". Mitsubishi did away with it because it was useless on the 05's. plus its connected to your windshield wiper tank, that after all the spraying on the intercooler. you dont have any more for you windshields.
