Those three buttons are without any feature, is there any parts could be replace it? such as cigarette lighter, or USB connector?

 

You use them for switches when you add in accessories - ill post a pic in a sec

 

Disregard dirty car. About to wash it. ILX snow foam bukake to follow. Red switch is for the light up bubble shift knob, blue switch is for puddle lights. What will your switches be used for? Only time will tell....

 

I'd like to replace it as cigarette lighter, or USB connector

 

I want to get my fog lights wired alone to a switch. Then they could be on whenever the car is on, be it with DRLs or low/high beams and they can be switched off for there was any reason to be.

 

The ILX Hybrid has a traction control switch on the far left button. Other than that, you can customize it with whatever you want as usdmJON said.
