Not sure if this should be under the technical section but is there a way to modify the cruise control to be set to a position on the hsi and not based on the speed. After all it is all electronic.

View 18 Replies2012 Prius with 10K miles.
One of the features I really like over the '06 Prius is the ability of the cruise control to hold the set speed on downhills (until the battery fills up and it switches to compression braking "B" mode, but that's a different topic).
After taking it in for the 10K mile service, it no longer engages regenerative braking on downhills with cruise control set. This is on the same hills where previously it would hold speed.
Did Toyota do a software upgrade that disables this feature?
So my cruise is giving me issues, won't set the speed. Turns on and off no problem but set and resume do not work. However, turn off the car and then re-start it and the cruise works again. I know the radio is only up to 60k.

View 20 RepliesIf i am driving say for 15 mins on the highway at 65-75 mpg with a few brakes and accelerations in between due to other cars around, is it better to use the cruise control (i have adaptive cruise control on my prius v) and let the car figure out the throttle and braking or is it better to just drive by myself without using cruise control? i read about the different pulse-glide driving methods.
View 19 RepliesMy 01 tundra can bog down under load - going up a long hill or towing a trailer - with the speed and RPMs steadily dropping until it finally downshifts, and the RPMS shoot up to 4k or so, but I don't regain much speed. This is without cruise control. If I have the cruise control on the problem does not occur. The truck slows, but in a normal way expected under the circumstances. The CEL is not on. No codes are being recorded. The Tranny fluid is full and smells fine.
View 18 RepliesAs odd as it may sound, our Prius salesman told us we should not use the cruise control on our 2010 Prius II for the first 1500 miles. We could not find any such warning in the manual. Did we just misunderstand or was the salesman correct?
View 10 RepliesTwice now, while going downhill hill (steep grade on freeway) my Prius has revved up to over 4,000 RPMs with the cruise control set at approximately 65 mph. The noise of the engine was my tipoff and I immediately had to turn the cruise control off. This just doesn't make sense to me! Seems like this could be a potential problem for those of us utilizing cruise control!!!
View 15 RepliesAbout 2 months ago, I was driving and my cruise control wouldn't engage on the highway ... I happened to be right near the dealership so I immediately returned there .... didn't turn off the car, but the tech put it in P while I was waiting. I was so ticked off because I thought that may have 'reset' things, and of course when the tech took the car for a drive (in D) the cruise worked fine. We of course never confirmed that the cruise control didn't work.
Today, the same thing happened at the same place, so I returned to the dealership, calling them on the phone, and informing them that I would not turn the car off, or allow the car to be put in park. The service manager met me out front and we went for a quick ride so I could 'prove' that the cruise was inoperative. He confirmed that it was not working, and why. For some reason, I glanced at the dashboard and noticed that the car was in 'B' mode. I mentioned that to the manager and he noted it as well. I must have bumped it somehow while driving as I NEVER use B mode for anything ... ever. I said I wondered if that was the reason, and put it in D, and lo and behold, the cruise worked again.
I haven't checked the manual yet to see if this is stated there, but the cruise control is inoperative if the car is in B mode. Or at least it seems that that is the case. Other than the car being in B mode, it acted just like it always does, and since I was on the highway, I never noticed the braking effect that B mode gives you.
I've heard that cruise control reduces mileage. This was in relation the Honda Civic Hybrid (Gen II).

View 12 RepliesI have had my 8 month old Prius for a week. I have used cruise control fine before and after the incident. All of a sudden we started slowing down. Doing any thing on the cruise control had no effect. I canceled it. But every time I pressed the accelerator I just got the amber warning light come up and the car beeped at me and no acceleration. The cruise control didn't get the car going either. I had to stop on the motorway. Put the car into park then put it into drive and drove off fine and the car has worked fine since.
View 10 RepliesWe have 2 trips coming up this summer (600 miles and 1400 miles), these will be my first long distance with the Prius.
Did anyone tested fuel economy using the cruise control in ECO vs NORMAL vs PWR ?
What are the most and least optimal times to use cruise control at highway speeds?
View 16 RepliesCuriosity question. I've noticed that on a downhill of a couple miles, especially in "braking" mode or with the cruise control on, the motor/generator and engine are used to keep the speed down and the battery gets charged to the very top quite quickly. That's good!
On a really long downhill, will the motor/generator still be used for braking and the excess electricity discarded to keep from overcharging the battery?
My vehicle shows currently two awkward behaviors:
1) I can start the vehicle using the keyless start button without having to step on the brake pedal.
2) I can switch on cruise control. The green symbol appears, however, I cannot set a speed. The system simply seems to ignore that I press the set button.
My 2010 Subaru Outback recently surprised the hell out of me by simultaneously turning on the brake warning light, the traction control light, the check engine light and (just for a bonus!) disabled my cruise control while flashing the cruise control light. I pulled over, quickly surmising that all of those systems could not have failed at 70 MPH without instantaneous death to either me or the vehicle. Both apparently still being alive, I tried turning the car on an off to reset the lights. No go. Subaru was not going to miss this chance to get me to the dealership! (who I had avoided to this point!) As I was far away from home and the car being very healthy, it seemed, I decided to drive on. I proceeded to put a couple of hundred more miles on the car before I got back to town.
My car had 39,000 miles on it, 3,000 miles beyond the warranty end. I learned that I have an error code of P0171, "Fuel Trim Malfunction (Air/Fuel too lean)". So I guess I'm wondering about a few things...why would this sensor set off every light on my dashboard and disable my cruise control? Seems a bit overblown for running a bit lean. My gut tells me Subaru has a sensor/software problem they are not owning up to. I'm a big fan of conspiracy theories and this really smells like one...
Second, jeez, I'm only 3K miles over warranty, don't you think they'd cut me some slack. I mean I love my Subaru, or did anyway, until this happened. Now it's just another POS car that breaks for no apparent reason...
My cruise control will engage but not maintain set speed. It slowly loses KPH, 10 KPH every 30 seconds. What to look for?
View 6 RepliesThe cruise on my 2013 LS460 SWB RWD sucks big time! Both Dynamic and Normal cruise modes are WAY too sloppy in speed regulation. I was out today on a 55mph PSL two-lane with set speed of 59mph. On a long SLIGHT downhill, the indicated speed topped out at 70MPH!!!
BTW, tranny shifting was weird during this episode with a prolonged run at over 3k RPM. At any rate, that's 11mph over the set speed for the arithmetically challenged. So instead of tooling along at a maximum of 5 over the PSL as my 2007 LS would have done (set speed 59 + overspeed 2 = 61 indicated = 60 actual, so 5mph over PSL), I'm flying at 10mph over the PSL ripe for the picking by any county sheriff (and I saw THREE of them on that road, all with their radar on).
I figure my car's speed regulation (in both Dynamic and Normal cruise) is +11mph/-2mph for set speed of 59mph. That is crazy!
