Lock And Unlock
WARNING: This page is about a different car, the 2016 Jeep Wrangler and 2015 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.
The system locks mechanically the shifter into the PARK position. When the key is in the ON position (3) and the brake pedal is depressed, at least one half inch, the shifter is unlocked and will move into any position.
