turning on fogs.
To turn on fogs, look at the lights stalk.
On the stalk itself, there should be a collar with a light symbol. Turn it forward.
I drive with my fogs + headlights on all the time.
You can leave the fogs in the "on" position regardless of your headlights being on or off.
You can also leave your headlights turned on, turn off the truck and when you open the drivers door, the lights go off.
Did you get a owners manual? It's in there. If you don't have one, get one.
