Somehow I got into a mode where just by keeping one finger on the wheel, my 2026 Prius would negotiate most curves in the road. Then I lost it. What combination of options gets it back? TIA Don (central VA)
I assume you mean the car would steer itself as long as you kept a finger on the wheel? If so, make sure you are still in Dynamic Radar Cruise Control and you have Lane Tracing Assist turned on. DRCC is selected using the steering wheel button with the word MODE underneath a little speedometer symbol(northeast of the cruise control cancel button). LTA is triggered by the button just above it marked with a little car between two dotted lines. Lane Tracing Assist will keep the car centered in the lane, but it only operates in DRCC. Lane Keeping Alert operates all the time, but all it does is give you a beep when you start to leave the lane and bumps you back into it. If all you used was LKA, the car would just wander between the lines like a bowling ball going down the lane when the side bumpers are up. (The system would shut itself down before it got to that point, but that would be the effect if it didn't.) But I'm guessing you just bumped the LTA button and accidentally turned it off.
