I just bought a 2005 LR3 HSE TDV6 and am learning how to use everything. It also has the locking rear diff option. My question is about the center diff. When selecting one of the terrain response choices and turning on the driver info screen, the center diff shows unlocked. Is there any setting where the center diff will be locked more than others as I have yet to see the screen show it locked. I was slogging through mud today in the mud setting but never saw either center or rear diff show as locked. Enjoying the vehicle greatly though. Thanks
