It's your owners manual

 

ok i think im just going to throw this out here:

switch the knob to 4Hi while in D dosent have to be stopped as long as below 50 mph or whatever i guess just dont flip it on doing 90, you should hear a click and solid 4Hi light on.
put it in N or P and go to 4Low its gonna flash you might need to rock the car a bit till the light is solid.
put it in drive and dont try to race nobody, but there is where you should be able to go to crawl mode and select the speed.

please do not try any of that on pavement as you will grind your gear and then say the truck is a peace of crap!
