Does your 2010 Prius roll backward at 1ft/sec in D gear on an incline, foot off brake, accelerator?

2010 has a anti roll feature. press the brake hard and it locks for 3 sec or so, there is a indicator on the dash when in this mode.

If you have ever drove a standard trans this would not be a concern. I drive up steep hills and have to start off from a full stop. the roll back is like one would feel as in a standard transmission.( manual )

My Honda cars do hold on hills. they to not use the CVT style transmission.

I am very pleased with the 2010 Prius.

That's crazy talk, an electric motor doesn't need to go backwards first. If you're concerned, use the roll-back feature by stepping on the brake a little harder, until it beeps and a yellow light comes on. That locks the brakes for about a second, plenty of time to move to the accelerator.

I tested this on a friends steep driveway, and found that I didn't need the roll-back feature. I learned to drive with a manual transmission, so going from the brake to accelerator is quick.

You can also come to a stop, and then apply the accelerator just enough to hold the car from rolling back, it seems to work fine. Just like on a manual transmission, you can let the clutch slip to hold the car on a steep hill, you can apply pressure on the accelerator to hold the car.

In other cars, I have been on such steep hills that I applied the handbrake to hold the car, but having a foot controlled parking brake doesn't work as smoothly for this.

I just use applying the accelerator. Find a steep driveway and practice a little with different methods until you feel comfortable.

And for some fun, look for and listen to Bill Cosby's old track on "Driving in San Francisco!"

Yes I think it does drift backward on a hill (2010). I first noticed the car would hold still on a slight incline. Pretty cool, I thought. Then I punched up the system display, and I saw the battery driving the motor to hold everything still. Hmm. Stepped on the brake, arrows go away. Now I know which method uses less energy!

Thanks...great old sketch...found it on YouTube. Go have a listen before the media rights police catch up with them.

They must have improved the design of their auto gear box. My last drove a Honda was 10 years ago. Toyota should also learn from them.

Me && Brad have the 2010 V w/ Adv. Technology.
So it has hill assist.

 

i will admint, i'm not sure if I hit the park button or not, but my 2012 v crashed today after rolling out of my driveway and down a slanted driveway across the street and in a deep ditch. so my fear is that hitting the break didn't make a difference even if it was in drive.

 

Sorry to hear about your Prius. I have stepped out of the Prius without pressing the park of start button more than once, but the car was parked on level ground. The beeper alerted me to my error and I properly parked the car. Did you hear the beeper when you got out of the car?

 

If you have it, a light will appear on the dashboard when it engages, at least in the 2012.

 

The HSD system does not have the intrinsic "creep" that a conventional torque converter transmission has when the vehicle is standing still in gear. In other words, if zero current were supplied to the MGs, the Prius would rolld down hills freely and stand still when stopped like a car with a manual transmission. So my take is that Toyota introduced some artificial creep to make the vehicle feel "normal" to those drivers who are accustomed to conventional automatic transmissions. So we're just talking about the magnitude of the artificial creep. To me, a center handbrake would would address this nicely.

 

I started a thread about this early last year about the car ROLLING BACK after stops and applying the gas pedal on steep hills like those found in San Francisco. People thought I was crazy but it was obvious they never drove on those hills. Everyone said use HILL ASSIST. Um yeah, like it's reasonable to activate it up a hill every few feet especially during rush hour. Anyway, my suggestion is hit the power button and apply the gas pedal fast when you let go of the brake on the hill. Will allow you to drive "almost" like a normal car up those hills.

 

Fuzzy1's comment seems to have gotten lost. Very simple solution that I used with older cars and continue to use today in my Prius when I am concerned about possibly rolling backwards from a stop -- left foot on the brake and increase pressure on gas with right foot when ready while decreasing pressure on brake with left foot. No need to change habits or think about how hard I'm pressing on the brake or timing. It's not difficult to do, and I don't even know how to drive a stick shift.

 

re: "I don't even know how to drive a stick shift." This is why it works so well for you -- your left foot has never been trained to perform an entirely different function.

 

I was doing both in my youth -- left foot for the clutch on the farm equipment and one of the cars, left foot on the brake in a really old automatic car. The later was needed because the engine very easily stalled if the right foot completely released the gas pedal during braking.

I had to break the left foot braking habit when that car was sent to the scrap heap, but it has come in handy in a few situations since.
