Back-up Control (Engine brake)

WARNING: This page is about a different car, the 2003 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.

If the selector lever is shifted to 2nd position while driving in D₄ (O/D) or D₃ , great driving force is applied to the clutch inside the transmission. Clutch operating pressure (line pressure) must be increased to deal with this driving force.
