    Is there a way to prevent interior dome lights from automatically turning on when ignition is turned off? This occurs even though no doors are open and dome override switch is in the off position. 2018 Limited

    That looks like a Techstream setting. Some trim levels may have access to that setting via the dash cluster.

    Thank you for the welcome and the feedback. Joe333x - yes, even with that switch in the off position. I will look into Carista or Techstream and see what I can learn. Thanks for the welcome to the site!

    They should not be coming on if that switch is in the full off position.

    Somethings up because when I shut that switch off the lights do not come on when I shut the truck off. I have techstream and don't ever recall seeing anything about that in the options. I can check when I get a chance.
