Back-Up Control (Engine Brake)
WARNING: This page is about a different car, the 2007 Nissan Versa. However, it is still accessible from the selected car via links, so may be relevant.
If the selector lever is shifted to "2" position while driving in D4 or D3, great driving force is applied to the clutch inside the transaxle. Clutch operating pressure (line pressure) must be increased to deal with this driving force.
