I don't know what this lever does. When I push it up towards the mountain picture, the lights flash and something displays on the dash screen.
Anyone knows what this does?

ps it is located right behind the shift stick.

 

It is part the the PTM system. It lets you select between 'high range' and 'low range' modes and lock the center differential.
