Near the cigerette lighter (power socket), there are two switches surrounding a large button. What are the switches? I'm looking at a couple of ssei'* on line, and one has them and the other does not. What is the large button in the middle - traction control?

Can you recommend I look for any other useful options?

The two rectangular switches are for the heated seats and the large square one in the middle is for traction control. I'm guessing all the lettering is worn off of yours?

Edit: And all SSEi'* have them I do believe. I know some of the earlier 00+ had them behind the shifter instead of next to the cig lighter
