Here's my post on this forum from 9-21-2018:
OK, I had some time parked facing a store window waiting for someone to finish their business in the store and decided to try all the various combos of IGN OFF/ON, Motor OFF/ON, all light switch position (off-auto-parking-lights), and trans in P or D. Did not fool with the parking brake, left it not set, and auto-hold was off.
Result, the only absolute definitive statement I can make after all this fiddling: If motor is ON and trans in Drive, DRL (orange led's under-headlight) are ON full bright and no manner of switch fiddling (including Auto) will turn them OFF.
All other combos of the above variables, I could not get a definitive repeatable behavior. The logic clearly knows if the trans has ever been in Drive and the motor was ON during some length of previous time.
At first start of the experiment, after I had been out of the car, car locked, in the store, for about 10 minutes.
Testing showed even with motor ON, I could not get the DRL's to come ON until shifting into Drive. They would be half-bright with the side marker lights when turning on the parking or low beams.
What was surprising was how much permissive logic must be satisfied to just get the low beams to come ON, and never could get the high beams ON with the motor OFF.
Looks like a lot of logic is at work in the lights control system to protect the battery from run-down.
Consumer Reports Magazine's recent new car issue dings the Sorento for being too easy to turn off the DRL's. I've never found an easy way to turn them OFF once they decide to come ON.
