Difference between PDL lock and off road switch

The "off-road" switch is used when the GPS doesn't comport with reality and you have to make the turn onto a road that the GPS thinks is paved but is not.

 

You're right. It's also for all wheel drive functionality also if he would need it. ThAt truck also has a turbo button for advanced operation and maneuvering.

 

The PDL for your power door lock operation. The off road has a driver feedback tutorial functionality option as well.

 

Not exactly. The driver tutorial switch will decipher the difference occasionally and will allow driver options of choices to function truck specifically sand without pheasability.

 

Does it have the Dip button as well? May be dip? Not sure exactly. nse

 

If you leave the mud and snow switch on, like I did all last winter, it snows everywhere. I shut it off and the weather is nice again. Sorry

 

I thinks that's the ats button?

 

The PDL (power divider lock) is only used in times of low traction at steady speeds. You might use it through a snow storm, traveling down a muddy road or even backing under a trailer where your tires might spin out. It is a separate unit from both differentials that will apply more power to the wheels that have grip and less power to the ones that are spinning. It's kind of like a limited slip differential on a car but a little more sophisticated. Do not use it full time like at highway speeds on dry pavement or you might tear up axles, gears and seals. Use it only like driving slower in the snow where your tires can spin out. Failure to use can also cause problems if you are constantly spinning in snow. I wouldn't use it above 35 mph and for short periods or it will heat up from abuse. You can engage and disengage it while moving but not under throttle. You will get a solid light when engaged. If you are going too fast for it the light will flash about once a second, slow down or turn it off. Some trucks have an audible alarm if you are traveling too fast. If it flashes real fast like 2 times a second indicates you have problems with it.

Off road is your differential lock and should only be used in a pickle like stuck when stationary or below low speeds like 25 mph or like climbing a snow covered hill at low speed. If I ain't mistaken which I don't know a Prostar but is the RF and RR drive tires.

The two switches can be used together for maximum traction but at only low speeds and conditions that warrant it, like trying to get up a snow covered hill at 15 mph.
