WARNING: This page is about a different car, the 2017 Jeep Patriot and 2017 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
When selecting between N (P) and D (R) position, the optimum operating pressure is set on the basis of the throttle position, the engine speed, and the secondary pulley (output) revolution speed to lessen the select shock.
