Mine is a newage so may not be the same. has a button to the top left
of the gear lever console, if this is what you mean i have never pressed it,
when i was first looking at buying the car the owner pressed the button to roll
the car forward when the keys were not in the ignition, took this to mean the
button was to unlock the transmission from park when the engine was not running!
Am assuming you're not talking about the button on the gear lever itself, my car
has a very small button on the gear change console, hope this sort of makes sense?
