In my 2022 ES350 I occasionally use the Lane Centering Assist while on interstates. It is biased to hold just right of center. It’s close enough to the lane to my right that I worry about a mirror clipping a wide truck. I’ve verified this by following my car while someone else drives. Has anyone else noticed this? Can it be adjusted by a dealer?

 

I think it's more lane keeping assist to make sure you don't cross into the next lane. Unless there was a significant change to LKA for 2022...

I wouldn't be relying on that regardless prevent yourself from clipping trucks lol. If the margin for error is that slim, a gust of wind will just about do it regardless.

 

The Lane Centering works best if the Dynamic Cruise is also on. Does not have
to actually be set to a speed, just press the cruise On button and see the green
icon down by the Odometer and LTA light.

 

Lane Centering is a function of Lane Tracing Assist, and must be engaged after LTA is first engaged. I certainly don’t rely on it as an “autopilot,” rather as an added safeguard. Or at least I’d like to if it didn’t find the center to the right of the actual center.

 

Lane Centering works ONLY when the Dynamic Cruise is turned on and set. So only why you're actively using Dynamic Cruise will the Lane Centering function work. And LTA is turned on of course.

 

Next time I use cruise control, I'll try this lane centering thing.

 

Make sure LTA is turned on and Lane Centering is turned on the settings screen of the MID. I find the ES Lane Centering works fairly well and isn't nearly as obtrusive feeling as the RX.

 

Dealers should have a calibration procedure for vehicles equipped with LSS (Lexus Safety System) and BSM (Blind Spot Monitor). For a hint as to what is involved see the Tech Tip L-TT-0245-18 pdf Target Placement for LSS and BSM Calibration which includes the ES 300H and ES 350 in the list of applicable vehicles. (One of the contributions of increased repair costs for modern vehicles is the cost of recalibrating the vehicle's installed safety systems.)

In case you haven't already done so, I suggest you repeat your verification of the right of center bias and take a photo showing the bias in relation to visible roadway markings. With the photo the dealer's service manage and technicians will be able to see with their own eyes the deviation from center you're complaining about and should be able to tell you in concrete terms if the system is within calibration limits or not.

 

Thanks grp52. I will have my wife and daughter tail me and record it and then bring that documentation into the dealer at my 5,000 mile service.

That Tech Tip is very involved. I see the reason for documenting the issue!

 

Just tried LTA right now with DRCC. Worked pretty nicely, perfectly centered. Even worked on a somewhat mild curve... but didn't work on a more aggressive curve on an off-ramp.. lol
