It happened today the Differential Lock light is on, I feel the difference right away on the parking lot and start nervous, could not figure out what is the light do. Pull the manual and read, found out the switch is below the steer. I guess my knee might touch the button!
Anyway, push the button, the light starts blinking, not turning off! What to do? Eventually find out the trick is to drive a few feet on the parking lot, the light is magically off!
Hopefully it will helps.

 

Its extremely useful off-road!

 

That's how it functions

 

I did the same and drove it for 20 miles and thinking this truck is so difficult to drive.
now lessons learned after watching lots of articles and videos on how central differential works.

I used to think the "X" in the light means breaking up the front and rear wheels so it means unlock,
but actually the "X" means disable the central differential, and then means locked front and rear wheels.

confusing icon and could lead to mis-understanding....

 

agree. especially for the critical controls like this one!
