    I have a 2021 TRD Pro. Has anyone successfully turned off the radar feature on cruise control? I don't like my car automatically breaking itself.

    Hold the cruise control activation button in for about 3 seconds when you turn it on. That activates it without the radar feature. You will see it say "radar off" for a second in the notification center on the dash when it turns on.

    Awesome, thank you! Will I have to do this every time I turn my car on/off?

    From what I've experienced, yes. Each time you activate cruise.

    Speaking of cruise control has anyone noticed that it revs really high while CC is on? I can go 80mph under 2500rpm, but once CC is activated it acts like it's being dropped into a lower gear, and even on flat terrain revs at about 3500rpm

    Part of me was hoping it was just an issue with mine and it could be fixed, but I'm also glad I'm not the only one that has experience this. There are a few things I need to take it in for. The Apple Car Play volume with navigation doesn't work. It is always on super loud and it won't adjust. The rear view camera isn't centered at all. And I supposed I could have them check the CC just to see if there is a simple fix.

    Does it only do that on flat ground, or when going up hills? Mine will do that going up hills, it doesn't know that it needs to work up a little extra speed before the hill, so then it will downshift and get the revs up because the engine doesn't have the power to make the grade without downshifting a few gears. However if I'm on flat ground, it's the revs are exactly the same whether I'm using cruise control or not.

    Yeah, if yours does it on flat ground it almost sounds like it's not allowing the transmission to shift into 5th gear. Unless perhaps you're on a slight grade, or driving into a headwind where the motor doesn't have enough power to maintain that speed in top gear.

    You make great points! I'm in Texas, so usually I'm on a flat grade, unless I'm driving through hill country (San Antonio/Austin), and what I think is flat may actually have a slight grade to it. What usually happens, I'll go up a hill, it will downshift to get up the hill, and then even when I'm going down the hill on the other side the rpms remain the same /high. I just need to go in and have them check it, Toyota is usually pretty good about taking the time to find the issue. Unlike Ford, when I owned one in college, haha.

    We have the Radar Cruise Control in our 2020 Rav4. I kind of like, at least until I get behind a really slow driver.

    There was another thread about this recently. Basically unless the ground is completely flat with 0 elevation changes, the cruise sucks

    Sooo. 2021 TRD ORP and couple things want to see if ya'll have experienced

    1) when the cruise is on with the radar and it adjusts speed is anyone else hearing a 'clicking' sound from under the dash?
    None of my wife's RX350's (2) and now NX300 have I ever noticed any sound whatsoever. I assume it's all the same tech between the two - could be that Lexus sound has some sort of sound deadening and i'm just not hearing it. It's not that big of a deal all in all but still slightly annoying.

    2) Also, driving yesterday in mild rain the dash light's up with two amber lights - a caution triangle, and what is supposed to be front radar - info center says "radar cruise control unavailable Clean Sensor"
    The sensor was not covered in anything except the rain water. No mud, excessive bugs -anything. It stayed that way for a couple miles, then went off and worked fine since. Found that odd.

    Oh and yeah - I do know that using cruise control in rain conditions can land my ass in a ditch....

    You’re not supposed to use adaptive cruise in the rain or in the snow.

    Can't we turn off the adaptive part after activating cruise control in one of the menus? I think there's a menu with the lane lines and the three horizontal bars with which you can select the sensitivity. Or maybe you can just adjust rather than deactivate?

    No clicking behind the dash when using CC on my 2021 ORP.

    That clicking is likely the brakes. If the vehicle can't bleed off enough speed by coasting, it'll apply the brakes a bit. It happens when I'm using cruise and headed down a long hill. Or, if I'm approaching a vehicle ahead that's traveling much slower than expected.

    Mine clicks (MY22 ORP) too when activating the brakes while using adaptive cruise...sounds like a relay of some sort in the steering column. Debating asking the dealership to replace parts if its not normal.

    Mine clicks as well when it applies the brakes.
    RPMs are not higher on mine than when I don’t use CC although I don’t think I have set the adaptive CC above 75 mph so far.
    My wife’s 2021 Hyundai Elantra also has adaptive CC and it seems a bit smoother than the one on the 4R. For example, if a car turns into my lane in front of me but still goes somewhat fast, the Elantra will slow down gently and match the speed whereas the 4R kinda brakes abruptly to match the speed (I’m slightly exaggerating but I can definitely feel the difference).
    Also wish it would work all the way to a stop and keep going when the car ahead moves like it does on the Elantra.

    Overall I’m happy to have it though, it’s definitely nice during morning commute when there are a lot of cars but speed of traffic is still fast.

    yep - the 4Runner is violent with both deceleration and acceleration - definitely an area where the engineers didn't massage it's behavior before release.
    I love the adaptive cruse control though - My wifes vehicle is Lexus SUV - it's adaptive cruse is very finely tuned.

    I love it regardless of the whiplash ..... LOL

    My GF has an Elantra as well, and it's crazy how much smoother a 20k Elantra is compared to a 40k(+) 4Runner. We just took it on a trip up into NH, even in the mountains it averaged 42mpg and didn't struggle on the grades at all, where my 4R would have been wheezing like it was in pain.

    Obviously I'm not taking it off-roading, but what a great little commuter car.

    The clicking is a relay.

    If my CC is reved high in 4th, tapping the accelerator forces it to upshift. Also, I found that holding your foot ever so lightly on the accelerator in hilly terrain with CC on, the vehicle will not downshift attempting to slow you down to the CC set speed.
