Friends,

I ask for your advice and opinion on the suite of driver "aids" in the LC 500. I come from an older BMW with no parking sensors or anti-collision/lane keeping/HUD stuff. My better half has an older IS and she loves it - and I was all in on picking up a new LC 500 to replace my coupe...but then the Missus took her IS in for service and got a 2025 SUV for a loaner. I simply cannot (or at least, will not) tolerate the intrusive nature of the driver aids. Since LCs are not really test-drive type cars, I ask you if disabling (or at least minimizing) those "features" is possible. If not, I'm afraid it's back to Stuttgart. But I really, really want an LC...

 

Everything can be fully disabled. There may be a handful that you have to disable each time but lane departure, hud, sensors etc. can be permanently turned off. It's the pre-collision that I don't recall if it will stay off or if you have to turn it off each time.

 

I'm so grateful for your feedback! I hoped so, because honestly my heart is with the LC. One last question for you, if that's okay. Our driveway has a bit of an incline. When backing into the garage, the collision detection on the loaner got scared and hit the brakes...abruptly and firmly. Is that one of the features you can permanently bypass? I appreciate your kindness.

 

Yes that is rear cross traffic alert with emergency brake, it too cna be turned off but I don't recall if it remembers your setting

edit: LC has RCTA but does not perform any emergency braking function wrt parking sensors like other models i.e. PKSB function.

 

Brilliant. Thank you so much. I've got an appointment to meet with the dealership's GM next week, and will likely place an order for a new coupe. Your feedback really helps.

 

Definitely check by turning the settings off, powering the car off, then restarting to see which ones it remembers.

 

The most intrusive is the lane trace assist. You can permanently turn this off.
The other stuff like blind spot monitoring is quite useful. I can’t think of any other driving assist that would bother you.
I agree, they should turn off the LTA on their loaners on default.

 

Hopefully more owners will chime in, but I'm one of the front-page Content Editors for ClubLexus. As part of my job, I get to borrow and test drive many different Lexus and Toyota models. I too have found the newer nanny systems, particularly the braking, to be overly aggressive in brake applications on many models. However, I've borrowed several LC models, mostly 2021+ V8 coupes and convertibles, and it hasn't been too aggressive for my tastes. It certainly beeps backing down inclines toward flat surfaces, but no sudden braking in my experience. Possibly because it's an older platform? Maybe because it's a sporty grand tourrer? I can't say for certain.

That being said, if you head over here -- https://www.lexus.com/My-Lexus/resou...d_guides_promo -- you can download the owner's manual for the model LC you're thinking about buying, or use an online interactive version. According to what I read, all the pre-collision nannies can be turned off via the Settings Menu (the cog) on the LC's digital gauge cluster.

 

Thanks for that, Nick. You're right about the LTA, and I agree on the blind spot monitoring. I just don't want the car to override my throttle inputs when I'm backing into my garage! Between the mirrors and the spectacular backup camera I've got it under control.

 

That would be the precollision avoidance system(PCA). It is quite useful!!!!
but you also can permanently turn it off.

 

Thank you for the kindness; I'm sure questions from newbies get tiresome, but I greatly appreciate the link to the LC owner's manual. I'll get to readin'!

 

FWIW I have rear cross traffic and parking sensors enabled and I get real close to my garage wall backing in and it has not once ever triggered automatic brake for me. It beeps like crazy and flashes red on the screen but it's never tried to stop me from what I'm doing.

Contrast to my Toyota minivan which automatically brakes multiple times as I pull into the garage, both forwards and backwards. I've learned to live with it as extra protection from the foot slip or momentary lapse in attention that will otherwise destroy my water heater and water softener

 

Great to know, amigo. You're all a bunch of enablers...not that I'm cross about it!

 

Just to close the loop - the LC does not actually have the "Parking Support Brake" or PKSB feature that the newer IS and other Lexus models have (which explains why it's never tried to stop me before). This is the specific feature that triggers the automatic brake when the car detects obstacles via the parking sensors, and is the feature that interfered with your loaner when backing up. So no worries there wrt your driveway.

 

Pink Floyd listener you are.
