Blue line in adaptive cruise graphic
 

Does anyone know what the vertical blue line means in this graphic? I can't find any information online and my dealership has not responded to my inquiries. It comes and goes and I can't determine what it means. Thanks in advance.

You get that line when the guidance is the car in front and not the white lines.

Ah-ha. That makes sense. Thanks for the quick response. Not sure why the dealership couldn't answer as quickly.
:)

Also the amount of them (3) means it will keep 3 paces, aka distance or lead time, from them. You can toggle it between 1, 2, and 3. I assume it's something like 2s, 2.5s, 3s lead time.

Assuming you have either a 2024 ES250 AWD or a ES 350, see pages 188 and 189 of 2024 LEXUS ES250, ES350 OWNER'S MANUAL USA AND CANADA ONLY:
In the illustration just under the "Indications on multi-information display" section heading on page 188, 🄳 points to the vertical line. (If you don't want to have that sort of steering assist active there are settings in the Multi Information Display (MID) where you can turn on or off where steering assist is active.)

The "Lexus How-To: Lane Tracing Assist" video starting at approximately the 100 second time mark also explains it:

That's a different function - "Vehicle-to-vehicle distance settings". JRBPilot was asking about the "vehicle following" mode of the steering assist of the lane centering function.

FYI, the description of "Vehicle-to-vehicle distance settings" along with a table showing the following distance corresponding to a vehicle speed of 50 mph (80 km/h) is found in the "4-5. Using the driving support systems" subchapter, "Vehicle-to-vehicle distance settings (vehicle-to-vehicle distance control mode)" section of the Owner's Manual (page number varies by model year and model type).

The distance for each setting does vary by vehicle speed. From the manual:

Yes, I understand how the "vehicle to vehicle distance" settings work, I just didn't know the difference between "lane centering" and "vehicle following". Owner's manual Pgs 188-189 was exactly the reference I needed. Not sure how I missed that when I read it before but I understand it now. Thanks for the quick replies.:)

Did they give you the manual?

Yes, I just didn’t see the explanation when i read through it the first time. Pgs 188-189 was exactly where it was. Thanks,

Talking about this... How far in the middle your car usually travels between the lines?
Mine seems to be to the left a bit more, it does not "truly" stay at the centre.
Is this how yours as well?
In the US, yours might be to the right though...

I agree. Mine tends to hold more to the right of center. Sometimes it even puts the right side wheels right on the lane line before it corrects.

Cool..
I thought mine had a calibration issue..
It saves me going back to the dealership haha.
It is annoying actually. It is not really centering it.
Driver should choose how much to centre the vehicle as well instead of having a set value.
I feel like I am fighting the thing most of the time.
It is also bad when motorcycles are passing me. I keep disengaging it.
Feels like motorcycles will hit me because I am close to the left line marking.

Well, you do drive on the wrong side of the road :p

FYI if you guys care about lane centering and ACC, you should probably check out comma with openpilot. It's the reason I bought my ES.

I've thinking about this for some time now. Can you elaborate on your experience? Which ES model/year? Have you tried the experimental features (red light, etc)? Thanks!
