Prius (2010-12) Fuel :: Do Cruise Control Impacts On Mileage?
I've heard that cruise control reduces mileage. This was in relation the Honda Civic Hybrid (Gen II).

View 16 RepliesPrius C Fuel :: 2015 - Using Cruise Control Would Give Better MPG?
I just got a new 2015 Prius C Three and have been reading up as much as possible. I wanted to know if using cruise control would give me better MPG. If it's just a matter of 3/4 mpg difference, then I would use the cruise control to rest my feet. But if its a big difference, then I would avoid cruise control.
My daily commute from Germantown, MD to Alexandria Va and back is about 40 miles each way: total 80 miles. 90% of that highway on I-270 and I-495. I leave after morning rush hour and again drive back after evening rush hour.
Last couple of trips without cruise I have been getting around 50~52mpg.
Prius C Fuel :: Using Cruise Control To Maximize Regeneration?
Did use cruise control to maximize battery changing when coasting to a red light or slowing down for a speed zone? Just keep in mind your vehicle will slow down fairly rapidly with no brake lights- so I tend to to do this during those glorious moments when there are no cars behind mine. When you see an approaching red light (with cruise control on) just hold the cruise control switch down and the vehicle will automatically power the generators to max. In this way you will not lose any potential battery charge to the actual brake pads. Be advised also the generators will stop and the cruise will cancel automatically at 22mph which is usually slow enough to avoid engaging the brake pads until you are pretty much stopped. Just thought I would share a neat trick with fellow hypermillers. **Also note this may be a less effective charging method than long drawn out braking but is most effective for rapid slowdown situations like unanticipated red lights, speed zones or expressway off ramps ect. and requires some skill to do safely.

As 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?

Twice 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 RepliesPrius (2010-12) :: Cruise Control Is Disabled If In B Mode?
About 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 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.

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 RepliesPrius (2010-12) :: Downhill Cruise Control No Longer Holding Speed
2012 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?
Prius (2010-12) :: Battery Charging While Going On Downhill Especially With Braking Mode / Cruise Control On?
Curiosity 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?
Subaru - Outback :: 2010 - Brake Warning / Traction Control / Cruise Control / Check Engine Light Came On?
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 fuel gauge is not working, nor is the cruise control, Had the truck looked at, was told the cruise was not working due to the fuel gauge not working?
Also when he hooked it up was told the dash gauge worked fine and the computer showed 60% which would have been about right based on mileage on the tank. My guess is that I need a sending unit?
Elantra MD (2010-15) :: Cruise Control Would Not Set
Ok, today on my way to work, I got up to speed and turned on the cruise control. It worked fine. I then stopped on my way to work to get a bottle of water. I got up to speed and went to hit Set. Nothing would happen. I ended up getting off at the next exit and turn off the car completely. Restarted the car and got back on the interstate. Got up to speed, turned on the cruise and hit Set. It worked. On my way home, no problems. It was just strange.
