Lane Departure Alert won't turn off??

I don't use it and one day I got a warning when I crossed a white line without signalling. I checked the settings. I'm pretty certain I have it turned off. Anyone have this happen and how can I cancel it. Re-starting the truck hasn't helped.
Thanks in advance for any help.

 

It's the button on your steering wheel. Bottom right. It's near the button to change the following distance on the radar.

What you are showing there is just the sensitivity, not the on/off.

 

DUH! thanks I was trying to turn it off through the other menu!

 

I found the lda completely useless. Maybe I'm a bad driver, but it just beeps all the freaking time. It may have been more useful if it was combined with the blind spot mirrors to warn you when it matters.

 

I like my dad borrow the truck once, I turned it on before giving it to him. He called me asking what that annoying beeping sound was, I told him to stay in the lane lol
