Help with Hill Assist!

Once Hill Assist kicks in, to get moving again remove your foot from the brake and press the gas. It's pretty intuitive.

I don't have a Gen 3 or Prius v (hill start assist is new w/the Gen 3), but to me, it seems like the solution is to not press the brake pedal so hard.

Also, from what I understand, it does NOT ever detect hills in order to decide whether or not to be enabled. Second, you should be able to go within if you press on the accelerator for a few seconds. I wouldn't screw around w/turning the car off, back on, etc.

 

It sounds like you have a much bigger problem and that your diagnosis of HSA coming on is a red herring.

I'll let a Gen 3 or Prius v wagon owner chime in, but I think they'll probably tell you to take it a dealer, esp. if it's easily repro. If not, try to take a video of it to show them.

 

I have never used the Hill-start Assist feature - pretty flat around here. Are you aware, once you activate the feature by stepping on the brake harder (with the car already stopped) that the brakes will stay applied for up to 2 seconds AFTER you release the brake pedal? Stepping on the accelerator should cancel the feature.

 

If the driver activates the hill assist, then the slip indicator flashes and a buzzer will sound once. This sounds different then what you describe.

From page 255 of the Owner's Manual "if the slip indicator light comes on (not blinking I assume); it may indicate a malfunction in the system. Contact your Toyota dealer."
This sounds more serious and like what you describe.

Let us know what the dealer says.

 

Does it only happen in reverse? If so, shift to D and give it a little gas before shifting back to R.

It sounds like you may be in "Ignition On" instead of "Ready", when you are trying to drive. When in "Ignition On", the only gears available are Park and Neutral, and the vehicle will not move under it's own power. Please make sure the you depress and hold the brake pedal before pressing the power button, then make sure the "Ready" light turns on. If you are having difficulty achieving "Ready" mode, check that your brake lights turn on when depressing the brake pedal. A misadjusted brake light switch may cause difficulty in achieving "Ready" mode.
Hope this helps.

Yep. That's another possibility. If the READY light's not on, then the car cannot be driven.

If one pushes power w/o pressing the brake, then it'll cycle between OFF, ACC (accessory) and IG-ON (most dash lights on, radio on, etc.).

 

Hehe, I was also thinking that it sounded like OP was in IG-ON. Then I thought to myself.... Nah... No way!

 

I totally agreed with you for explaining possibilities: Ignition on only and not Ready mode.
After I install the bypass kit so that my wife can enjoy her DVD on the run (I drive), the flashing P with arrow came on and I couldn't go to D. So I thought perhaps because I left the bypass switch ON all the time and it has to do with the parking brake signal. So I turned it off but did not solve the flashing P. I had to turn everything off and back on a few time before the system acts normal. This went on for a few days and went away even if I left the bypass switch on. I looked everywhere for the flashing P and basically the manual says "see your dealer".
Lucky me but until now I still do not know what is that yellow P with arrow means!! It can't be a parking brake because that is the RED one on the left.
