2023 Highlander - Cruise Control / Steering

Hey guys, just picked the wife up a 2023 Highlander...and curious if any of your wives or as a secondary vehicle have one with the Adaptive Cruise Control, LDA and LTA.



From their site, Toyota describes them as follows:

Full-Speed Range Dynamic Radar Cruise Control
Intended for highway use, Full-Speed Range Dynamic Radar Cruise Control (DRCC) * is an adaptive cruise control system that is designed to be set at speeds above 20 mph and uses vehicle-to-vehicle distance control to help maintain a preset distance from the vehicle ahead of you.

Lane Departure Alert With Steering Assist
When white/yellow lane markings or certain road-edge boundary lines are detected at speeds above 32 mph, Lane Departure Alert with Steering Assist (LDA w/SA) * is designed to issue an audio/visual lane departure warning if an inadvertent lane departure is detected. If the driver does not take corrective action, the system is also designed to provide gentle corrective steering for lane-keeping assistance.

Lane Tracing Assist
When Full-Speed Range Dynamic Radar Cruise Control (DRCC) * is enabled and lane markers are detected, Lane Tracing Assist (LTA) * uses the lines on the road and/or preceding vehicles to provide active driving assistance and help keep the vehicle centered in its lane.

I'm curious of the intended purpose of the LTA (or how you use it). When I set the dynamic cruise control, as long as I keep my hands (or a hand) on the wheel, it quite literally just drives 100% for me. What is the intended purpose of this...is it supposed to be just used as an almost-fully-autonomous driving mode when on the highway? Obviously you need to keep your hands (hand?) on the wheel and pay attention / are responsible for the operation of the vehicle still (that's not what I'm asking).

Her previous vehicle had the feature (guessing more similar to the LDA) where you basically drove, but if you started to veer out of your lane, it would jerk/quicly correct it (largely over-correcting it and basically causing a brief state of panic as the vehicle itself "let go" and returned full control to the driver who is already fighting that over-correction it a bit) - but I get none of that with the Highlander. It seems different - like it was kind of intended to just relax and let it "do it all for you."

Thanks.

 

I advise not use any of those systems. Instead pay attention to the road as conditions are always changing.

Recall related to Toyota Highlander the front bumpers can fall off.
