There should be no set bluetooth code for your vehicle. You just make up a code (no more that 16 digits) enter it in, then enter the same code from your hanadset.
Do you have a bluetooth manual? If not I can send you a copy in PDF if you like.
It should accept any code. Try 0000, then find the car with your phone and enter 0000 in the phone as well. It should work this way.
Does your car have Nav or just a radio?
here is the page from tha manual about paring you phone.
