When this car was made they put this tool in various places around the car, making it something like an Easter egg hunt. I did not find one and got one from the dealer.
For the first time ever I went to put something in the pocket on the bulkhead behind the driver and between the seats, under the umbrella clips, VOILĄ I found the multifunction tool. It has been there untouched since Nov.2003. Have a look if yours is missing it may be there as well.
I now have two and they are slightly different to one another, on one the part with the wrench looking opening is longer than the other. I think that another version has a bend in it, but I could be wrong. (for the first time ever)
