Prius C Fuel :: 2015 - Using Cruise Control Would Give Better MPG?
Mar 24, 2015
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.

If 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.

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.

I've heard that cruise control reduces mileage. This was in relation the Honda Civic Hybrid (Gen II).

We 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?

I'm kind of up against the clock. I am sure this answer is in a book in the car. But that book looked pretty thick.
My husband just told me that he did not want to take my car to the ball game because he can't stand the cruise control turning off every time it gets even close to a car (yes, I understand what this may mean, but I'm not driving with him and he is a grown man).
Is there a way to disengage the automatic turn off on the safety cruise control feature? He likes to be the one in control I suppose.

I have been using ACC a lot during my daily commute, it's really an effortless way to drive the car on a daily basis.
One of the issues I have been running into with it is that sometimes when the car in front (recognized by radar) accelerates and immediately decelerates to a quick stop my Sonata's ACC does not react and apply the brakes fast enough. The car will basically apply some braking power (~50%) while very quickly approaching the car in front, all the while triggering the rapid beeping of the Collision Detection system. Everytime this happens I have always had to manually intervene and apply the necessary braking power to stop short of hitting the car in front. This is pretty ridiculous to me since if the car KNOWS that it will crash without additional braking, and has the ability to apply the brakes, why doesn't it do so properly?

The cruise control on my 2013 works as I expected.
However the cruise control on my 2016 Sonata does not.
When driving at highway speeds (65 to 70 mph) in cruise control and the shifter set on "D" (drive) the transmission will down shift to 4th speed whenever I go down hill.
This might be intentional as a way to keep the car from exceeding the set speed, but I have never heard of this and it would seem to place more wear an tear on the transmissions.
Do the down shifting is engineered in or if it is a service problem that I need to have addressed...

I love the car and SCC is one of my favorite features. I've had good experience with the SCC most of the time - if car in front of me is moving and then stops, it reacts well. (Also was pleased to learn I can resume SCC from a stop by just tapping the accelerator, no need to hit resume like the LCD screen implies).
However, the one situation is when I'm going like 55mph, and up ahead there's a car stopped completely. I'll see a thing on the dash that the SCC recognizes there's a car ahead, but it won't hit the breaks till the last minute. Truthfully, I end up hitting the brakes myself in most of these situations.
I've got the longest distance selected (though i've tried it with short following distance too) and my car is a Limited 2.4 GDI.
SCC stops fine if slower car ahead stops. Seems a little risky when car ahead is already stopped (waits till the last second for brakes?).
I've also tried changing the setting for cruise control response from "normal" to "fast"...maybe i'll try "slow?"

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?

Does the prius v TMPS shows you the pressure in each tire or just give you a warning when one of the tire is low. How many MPG do we gain if we over inflate the tire to the max possible.

My cruise control doesn't work anymore. There is no blinking/cruise icon on the dash--period. Is this the result of the button being worn out or a relay/fuse? My little tank has 231k, so it has been used. BTW, I can't seem to find a write up for replacing the switch. Is there one?

We drive a 2012 Prius v (lowercase v for the Prius v wagon) 5 with a little under 20,000 miles. This is the situation:
Yesterday afternoon we were driving and the dynamic cruise control went out. The "PCS" indicator is now flashing, and the error code "E3" popped up where the cruise light used to be. If I turn cruise control off and then on again the E3 code will show up after a second or two.
I discovered later that if I turn the car off, turn cruise on right away, and switch to regular cruise that I can use regular cruise. The PCS indicator still flashes though. The interesting thing is that when the E3 code is up, I am unable to use either type of cruise control unless I turn the car off and switch to regular cruise right away. I am not really sure what happened or what to do next.

Is there a limit of cruise speed at 117KM/H on Prius v models ?Can it be unlocked ?

My Prius just stalled out on highway from cruise control @ 65 mph, so I coasted luckily off an exit, and before coming to complete stop the whole dash went black with exception of power steering failure warning light. I had it towed, at my cost of $95, to dealer for troubleshooting. They found that the fuel sensing system/indicator had worn, and cost for repair is $422+, as not under any warranty or recall. Fuel sense indicator worn out @ 105,145 miles...

In ordinary cars, the cruise control (CC) only has control of the throttle. That is to say, when the car encounters a hill, the CC system increases the throttle. Coming down a hill, the CC unit will reduce throttle. If the speed increases too much, the CC unit can not reduce the speed of the car. On especially steep hills, the speed may well become too high.
In contrast in my Prius v, I find that the CC holds the speed study even on steep downgrades. This is possible due to the hybrid system which regenerates power. Even on steep grades, the CC system holds the speed rock steady at the set point.

Had an intermittent problem with my Cruise Control engaging. The CC light would come on when the CC on/off button was pressed.
When the CC would engage the "set" light would come on and the speed would hold. On occasion the CC would not engage.
I looked are reread the owners manual.....NOTHING! I was double checking to make sure there was nothing different with the hybrid. (I have owned Toyota for a very long time...since 88').
Since the Hybrid is new to me, "shifting" is a little bit different. There is a "B" on the shifter which is mentioned for "downshifting". There is no mention that once you are done with downshifting that you must shift back to "D" for normal operation. The only mention is not to run in "B" for an extended amount of time.
So, when you are in the "B" position, the CC with disengage.

First it wouldn't turn on, at times now it at times won't work even though the light is on, on the dash. At other times it works as expected. I dun think it's the 12V battery, because when only the center console is on in diagnostics the battery reads 12.2-12.4 and 14.5 + when the engine is on.

Mine just quit on me. Nearly 180K. 2008 Gen 2. I watched that youtube video, they were working on a Corolla. Seems easy enough, it's a pricey part though. It's called an airbag clock spring. I don't think it's the stalk. The button feels the same as it ever did.

Very very odd thing happened. Driving up from Houston to Colorado yesterday. Snow tires mounted in preparation for the snow in NM and CO. Around 300 mi into the trip, the CEL (check engine light) came on. I was on cruise control, I did not notice the lack of power. Checking the battery, it was in the purple. I first opened the gas cap and screwed it back in. I figured the change in elevation or temperature may have had something to do with the CEL. Nothing. Gas tank was a quarter full.
At Lubbock, I pulled over and filled up. I played with the rubber gasket on the gas cap but decided it was going to be more trouble than I was prepared to deal with, without any tools. CEL stayed on for another 30minutes or so while I navigated through the city, covering another 20 miles or so. After a pitstop to pick up OJ, I started the car and the CEL was off.
Here are the variables:
Elevation delta - +3000 ft
Temp delta - -10F
The only thing I can think of is that the hybrid battery is getting long in the tooth (2008 MY, 103k mi), the wind in the high plains chewed through the battery power, and the long length of being in low charge got the ECU to confuse itself into thinking that the hybrid battery has bad cells, which it probably has a few weak cells.
