Jerry... Can you try something with that "clip" and then post the results in this thread.
Take that clip (like pictured below I assume) and plug it into the driver's seat belt female buckle..
Now, with that clip plugged in, start your JL and see see if you can drive your JL, forward, say 30 feet with the driver's door open. Also, try this going in reverse with the driver's door open.
I'm wanting to know if use of that clip as mentioned will prevent auto park from activating.
Thanks for trying this and letting us know how you make out.
