A locked differential will be supplying power to both wheels meaning if one slips, both are spinning and still not giving you the traction.

Snow, mud, sand are conditions for 4WD.

Your VDC (Vehicle Dynamic Control) is a good device for preventing slippage-in rain/snow so leave it on! The system is there to help keep you on your steered path. If your Titan should start to oversteer (fishtail) or understeer (plow forward), VDC will reduce engine power and/or apply braking pressure to specific wheels to help keep you on course.

4-wheel Limited Slip (ABLS) applies braking force to a wheel that's losing traction while directing power to the wheels with a better grip.

Those two systems are your best bet when managing ice/rain. If you are on ice 4WD will help ONLY IF you reduce speed and prevent tires from losing traction.

thanks for that info
not sure about LOL
