I started a thread with several questions, but this one seemed to fall through the crack.

I noticed on my truck, no key in ignition, when you push the stalk (headlight ****, shifter, what ever you want to call it) the truck makes a single beep sound. I am not sure what this option does. The head lights turn on and when you repeat the process, the lights turn off.

what feature am I exactly turning on or off by doing this?

 

I too noticed this feature shortly after buying my 2017. If you push it forward and the headlights come on, they are on a delayed timer for around 30 seconds I believe. I’ve used this feature for extra lighting when parking in my driveway and walking up to my house in the dark.

 

I’ll give this a try tomorrow and see what happens. Thanks!
