Cruise control

Anything related to the Kizashi can go here, but please look at the other headings first. Your topic may fit better under something else.

The manual actually says "4th, 5th or 6th gear", and I know you cannot engage the cruise at 50km/h in 3rd gear- I tried it and was confused why it wouldn't work. (That's why I read the manual and found the above info ;) )

PS: Remember I'm talking a 6 spd manual trans- not the CVT in manual mode. The CVT might be 40km/h (as most cruise systems seem to be that I've previously had.)

PPS: Just had another check of the manual and it says for CVT "select lever is in D position or the gear is in 3rd, 4th, 5th or 6th". It also does state speed must also be above 40km/h for both transmissions (- But I don't like my chances of getting anywhere near 40km/h in 4th gear without the engine being very unhappy!)
hmmm I did not get any info from the dealer regarding the manual, so I just assumed there is a speed limit ;)

btw. the CVT cruises with the engine @ ~1100rm and drops the rpm to this value once the torque converter locks and there is slight or none acceleration, which happens between 35-40km/h, at this rpm the engine is quiet if cruising, but under acceleration has a deep rumbling sound (if the acceleration is not hard enough to raise the rpms)

not sure how the manual gears are laid out, but I guess 1100 rpm should be fine for manual as well ;)
Your cruise control revs at 1100rpm? At what speed? I'm a bit confused

I think it's engine revs = ~ 1100rpm with the cruise control set at 40km/h (in a Kizashi with the CVT).

Correct. When cruising with CC engaged from ~40km/h to ~70km/h, on level ground, the rpms stay around 1100.

If. Never cruise controlled at such low speed. CC at 65mph I get around 2200 rpm. That about right?

65mph = ~104kmh,

I think my CVT is a bit lower at that speed, ~2000rpm

Has anyone noticed? This has become more conspicuous to me lately.
I thought I was alone noticing this too. Almost feels like it's "letting go" when you get under 10 or 5 mph coasting to a stop.

Yaaa exactly. Like you let go off the brake. But to me it's a lil scary as it made it unpredictable while I come to the stop, but at least at a very low speed though

Yes .. I think thats the torque converter unlocking. When you are slowing down, the gas supply to engine is cut and the revolving engine is a drag which you feel. When the speed drops too low, the converter unlocks, gas supply is restored and the engine starts to idle. This is the time you feel like "letting it go".

I completely agree that its not gentle and smooth.

I also noticed that when I break really hard, it even feels like the engine is about to stall and I see that the rpm drop below idle, then raise swiftly to ~1000 and then settle at idle. I think this is the slowish ECU trying to keep the engine running.

When you let off the throttle pedal completely, the ECM senses this as a coasting situation and cuts off the fuel completely as an mpg and emissions saving thing. As you slow down, you will eventually get to a certain rpm where the ECM decides enough is enough and turns the injectors back on just enough to support idle. Most cars this is around 1200 rpm, I haven't felt it in my Kizashi yet, so I couldn't tell you exactly when.

My wife has a 2010 Chevy Equinox, and when we take road trips (I always get to drive) I've noticed that the cruise control tries to maintain the set speed at all costs...which often means winding out the engine on long hills and subsequently killing MPG's. Otherwise it's one of the better CC units I've ever used.

Anyway, that brings me to a question for current owners: Does the Kizashi cruise control allow for speed adjustments in 1mph increments? The GM cruise control does which I find very useful, but the Kizashi cruise control is something I always forget to try when test driving..
