Prius (2010-12) Fuel :: ECO Vs NORMAL Vs PWR Mode When Using Cruise Control
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 ?
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?
Prius (2010-12) :: Gen 3 - EV Mode Disabled Due To Excessive Speed
I was under the impression that when you enable EV mode the car will stay in EV till around 40 mph or something close to it? I can't seem to go above 10 mph without getting a message stating "EV Mode disabled due to excessive speed"? Is this a glitch or can you really only go 10 mph? That seems pointless if that is the case.
View 18 RepliesPrius (2004-09) :: CEL Came On In Cruise Control Mode
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.
Prius (2010-12) Fuel :: Using Cruise Control For Better Mpg?
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.

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?
View 10 RepliesPrius (2010-12) :: Car Revved Up While Going Downhill With Cruise Control
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!!!

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.

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.

So the problem occurs while I am driving with cruise control on . Suppose I am driving at the speed of 80mph with 1300rpm, few seconds after I come downhill the rpm shifts to 2000 and comes back to 1300. Now I understand that the rpm will increase as I go up in order to maintain the speed but this problem occurs once I come downhill
And today also while driving without cruise control on I experienced the similar problem. I got a SE V6.
Ford :: 2013 - EV Mode Won't Work In Cruise Control?
I own a 2013 C-Max hybrid and I notice that during long drives if i engage the cruise control, I don't get as many EV miles as I do when I have my foot on the gas pedal and take it off when i have reached my desired speed. Does EV mode not work in cruise control? My feet start to ache a bit with constantly having to press and release the gas pedal just so that I can generate some EV miles.

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?
