From the manual: “In the vehicle-to-vehicle distance control mode, the set speed will be increased or decreased as follows:  For Europe Fine adjustment: By 5 km/h (3.1 mph) *1 or 5 mph (8 km/h) *2 each time the lever is operated Large adjustment: Increases or decreases in 5 km/h (3.1 mph) *1 or 5 mph (8 km/h) *2 increments for as long as the lever is held  Except for Europe Fine adjustment: By 1 km/h (0.6 mph) *1 or 1 mph (1.6 km/h) *2 each time the lever is operated Large adjustment: Increases or decreases in 5 km/h (3.1 mph) *1 or 5 mph (8 km/h) *2 increments for as long as the lever is held”

Oh Herbie, Herbie, Herbie…the thing is you clearly don’t know what a Techstream model code is do you. And, your point about setting the region to where you live suggests you don’t know a lot about how to get-around defaults and maybe change settings that aren’t designed for Europe etc. Why bother commenting when you have nothing useful to contribute?

The question was “Does anyone know if it's possible to change the fine speed adjust on the cruise control via Techstream?” The 3rd post doesn’t answer the question, it simply restates what we already know: “Default radar cruise control is in increments of 5mph…”. As this 5mph increment is DIFFERENT from the 1mph increment used everywhere else in the world outside of Europe, asking about whether it is possible to change the UK setting to the setting used elsewhere via Techstream seems like a legitimate and (for many) important question. Why are people on this forum so quick to misinterpret questions and rationalise the irrational?

The thing about a lot of variables is that they lead to a lot of permutations, and the thing about Techstream is that it’s slow and cumbersome, particularly with a laptop balanced on your lap…so do one.

‘Tis my pleasure. And perhaps you could refrain from butting in when you don’t know the answer.

Really? Show me where someone has answered the question about the +/- 5 mph increments for the radar controlled cruise control. PS: I have used techstream myself but there are a lot of variables that might determine the answer to my question (such as version of TS, region setting for TS, model codes, options, and so on). You really are a forum stereotype.

I mean a “permanent” solution via a techstream setting that allows the use of Radar Controlled Cruise but with the non-European +/- 1 mph increments.

Hate to break up the party of people queueing up to poo poo the idea that there might be anything irritating or dangerous about a cruise control that can only increase or decrease a car’s speed in 5mph increments, does anyone know the answer to the original question? That is, is it possible to change this setting so that it matches what everyone outside of Europe gets (which is 1mph increments)?

Stereotype forum post. Q: Does anyone know how to do X? You: Why would anyone want to do X? I just do Y.

Bear in mind that everywhere else in the world gets 1 mph increments for ACC. So Lexus chose to do this for Europe only. Also, every other car in the world uses 1 mph/kph increments. If I’m driving in a 50 avg speed zone for 20 miles and I want to gently overtake someone (as happens all the time), I don’t want to jump to 55mph in one flick. In fact, that’s insane, stupid, and dangerous.

I would really like an answer to this question as well. The 5 mph increments are infuriating & dangerous.

The 5mph increments are a Europe-only feature/insanely-dangerous-and-stupid-bug. Everywhere else gets 1mph increments. Can this setting be changed? Has anyone achieved or tried this?

This 5 mph/kph increment thing is a crazy & downright dangerous Europe only “feature’”. Everyone else gets the sensible 1 mph increments. Toyota obviously misread an EU law.
