Weird, I was just about to start a thread asking the same thing except for a 2dr coupe..
Any ideas? (don't mean to hijack)
O'Brien's aren't sounding very confident in what's going to happen..
Shift lock release allows you to press the button and change gears without having the ignition on. Broken down & towing etc..
The other button activates the gear change controls on the steering wheel.
