That's aftermarket add on.
Mine has all options (i think they called it the Permium package, there is also an Ultimate package but they are opposite of how they sound, ie Premium is top of the line, all options??)
Lets see, options;
HID lights
Heated and cooled seats
Factory Navigation
AWD (you either get AWD or 2WD)
Advance Trac traction control (in late 2004 they added RSC Roll StabilityControl to Advance Trac)
2nd row buckets (vs 2nd row bench)
Class III hitch
Entertainment system
Sun roof
Chrome accent rims
I think those were the only options. I'm not sure if there were different gearing options, mine is 3.73.
