I like the analogy - we should rename it "the scared cat switch"!

I have done some experiments in my 1.5 CVT this morning. Bearing in mind this is the first and last time I will use the speed limiter, as I consider it a device of the devil. I expect a car to respond to control inputs not sit with its brain in neutral!

At varying speeds from 45 to 65 mph with the limiter on I slowly pressed the accelerator, the limiter did not cut out until way past the accelerator resistance and was almost fully depressed. Pressing the accelerator more rapidly had a similar effect. My conclusion is it is not a limiter cut out.

With the limiter off I pressed the accelerator through the resistance at varying rates and car speeds. The CVT changed down before I got to the resistance. After the resistance there was an increase in engine noise and revs but I am not sure if the CVT reduced its ratio any more as by this time the car was taking off like a scared cat.

This is all a bit academic because the treatment I gave my car this morning was not normal driving, and you would rarely need to go beyond the resistance in normal driving in a 1.5 unless you were trying a risky overtake.

My conclusion is still it is an economy stop.

Thanks both. I took it to a local mechanic I trust for a look underneath on a jack. We verified the arb linkers are detached (left) and on the way (right), and he didn't like the state of the condenser which has the typical stone damage and probably causes the A/C leak -- though there could of course be others.

If these were properly fixed I'd happily keep the car as I'm struggling to find a better one for 300-400 more, which then could also have similar issues anyway. But I don't want to go up and down to the dealer chasing down an A/C leak. It seems to me like the dealer thinks he can fix them well enough to sell, and eventually sell the car for more then I paid. Otherwise it's hard to explain why they offered a fix last night then changed their mind today.

IMHO the indent is to fool the driver into thinking the throttle is all the way down. To put it in the manual would kind of negate its purpose.
We know why it is present on the manual version (speed limiter override), it says so in the user manual and I have one so can confirm that.  It indubitable performs the same function in the CVT and I can also confirm that because I have driven an HR-V CVT. Skyrider may also confirm that for the Jazz later.

So the only question to be answered is that if it also performs a kick down function in the CVT.
I experimented with it a bit last night. I don't think it performs a kick-down because the car can be kicked down without pushing the pedal that far. For instance I often kick-down to get the car out of Atkinson mode. However going past that notch does seem to get some extra power even after you've kicked down so I think Skyrider is probably correct. It's some kind of WOT (Wide Open Throttle) guard to prevent you accidentally demanding total power from the engine. Although if so I'm not entirely sure what the point is. It's also something that wasn't felt necessary on the CVT-7 or the Mk2 both of which I have owned :-/
Ok I think that answers our question.  It is just there for speed limiter override.

And I think you are both correct @andruec, @skyrider.  What would be the point in adopting that on a CVT.  The acronym speaks for itself.

If it's got other faults as well, you say the aircon doesn't work, I would go for the refund.

Hello thank you for replying. Unfortunately I had. Bought the car second hand and orderd a nice sporty looking one from ebay but it's noway near the size for my hole. It must be for the 2nd gen jazz.
