Hi I was driving (2011 Lexus gx460)and my knee accidentally hit the central differential lock and was middle of traffic so couldn’t disengage it right away. As I was driving smoke started to come out but pulled over in time and it stopped once I was able to turn off the central differential lock. Car smells burnt but driving like nothing happened is this something I should be worried about?

 

I am skeptical that the smoke has anything to do with this. Where was the smoke coming from?

Yes, the manual says to unlock when on hard surfaces but unless you are making a lot of turns, the drivetrain would not be binding up. Where you making a lot of turns? Also why didn't you just push the button to unlock?

smoke was coming from rear and I was pressing it to turn off but was flashing and had to YouTube it reversed it and it turn off and smoke went away. I was on the free way when this occurred so no turns at all which I found odd. The button was stuck and wouldn’t let me turn it off

 

From the owners manual:

Were you "dragging" a tire ? ... if so, the tire compound can heat up pretty quick and smoke. Was it a dark(er) smoke with a burnt rubber smell ?

 

it was a white smoke tires seem to be fine. But a distinct burn smell of rubber or sum sort
