Default MTs and Hill Start Assist

For the MT owners, do you like the Hill Start Assist function on this car? I picked up my Impreza last Saturday; didn't even realize it was doing this. When starting out on hills, I was doing my usual very quick transition from the brake. It had seemed like things weren't going that smoothly for me, though I'm still getting accustomed to the clutch engagement point and throttle response. I was just reading about this in the manual last night. I'm going to have to do some experimenting now.

Is this something you guys like or do you prefer it disabled?

I dont ever notice it. i switch from brake to gas while letting off the clutch and time it right. I do know that sometimes when im on a hill it would be nice to creep back a little if i was too far on the line. It wont let you do that unless you shift into R

I like it, it can be disabled, but it will throw a warning light on the dash and you have to disable it every time you start the car (I think).

I can (almost) see the point of some WRX/STI owners who dislike it, because it can impede a fast launch, but if you are driving a regular impreza, it isn't an issue IMHO.

Having never had Hill Assist in any of my other cars, I find it intrustive quite a bit of the time. There is that split second, especially when the car is only on a slight grade, where the damn car won't move when I apply the gas and I always wonder why. Then I remember, ah... Hill Assist... and I think about disabling it.

I think a less aggressive system, or possibly one that reacts more quickly to pedal inputs would be better.

The Impreza is my first manual transmission car, so I found it extremely helpful while I was still learning the ropes. It's certainly never bothered me, but as I said, this is my first MT car.

It works by holding the brakes until you have released the clutch past a certain point. Some posters in another thread have said that they were able to adjust that point, making the system much more unobtrusive.

Interesting. Any idea what that thread was called or how long ago it was posted?

I keep it disabled. Visibility is often poor on steep hills and it's nice to be able to roll back out of the way. Also, being able to parallel park on hills without shifting is a good thing.

Do you manually disable it every time you drive? As I recall from the documentation (and as Zeeper mentioned above), I don't believe you can disable this feature once and have it remain disabled.

My recollection is that it remains turned off. However, there's a warning light on your dash all the time.

I like it but at the same time I get annoyed. When starting off on a very minimal incline/decline, the car does not move for a good second. But, it is handy when you're starting off on a major hill in SF.

I was experimenting with it today. It was nice on steep hills, particularly because I feel like newer vehicles using throttle-by-wire don't have the immediate throttle response that older vehicles once did.

I grew up driving manual transmissions; I have yet to own an automatic. I gave it some hard consideration this time around though. My last vehicle was a 2007 Tacoma. Still is actually, I'm keeping it as a second vehicle. But it was the first throttle-by-wire vehicle I've driven, and I never liked the goofy things the computer would do with the throttle. The Impreza seems to have some of the same traits (slightly delayed throttle response, RPM hang, etc..), but they aren't as bad as the Tacoma, or maybe I'm just used to them now.

But back to the HSA, I agree that on a very light grade it was occasionally a real annoyance. Several times I could distinctly tell the brakes had not let off while I was trying to move. There was a slight delay.

One thing I think is kind of crazy is that after 2 seconds the HSA releases the brakes whether you've started to engage the clutch or not. If it's going to hold me there, I actually think I would rather it just hold the brakes on indefinitely until I do something, rather than give me an arbitrary amount of time and then let me coast backwards into the car behind me. If you do want to coast back, it's easy enough to momentarily take it out of gear.

I turned it off day 2 of ownership, it does stay off. Sometimes I wanna roll back, like when soccer mom in her windstar is thinking about getting a tad too close on a hill. I dont't even notice the dash light anymore.

If I want to roll back, I don't have a problem going to neutral. I tend to keep it in neutral when I'm stopped anyway until I'm ready to move forward.

I think it's kind of crazy though that it gives you 2 seconds and then let's you roll.

I don't mind it. I can get going nice and easy with it. Little more gas and same pickup point.

Why that is more than enough time?

Typically unless you somehow fumble the transition. Bottom line though I just don't like something as important as the brakes being locked on left to a timer, particularly a timer that I can't see. I'd rather something like releasing the brakes require user input. If I want to coast backward a bit, I can easily put it in neutral momentarily.

IMO, all manual transmission cars should have it. My 88 Subaru had it and I was glad the Impreza has it.

The parking ramp at my work is under the building and you have to wait on an incline for the automatic doors to open and it comes in very handy.

I don't understand why anyone would "hate" it.

Not a fan of the hill assist. It seemed too abrupt and unpredictable, but maybe I didn't give it enough time to try and get used to it. I disabled it a couple days after getting the car. For me, it was just a weird sensation to try to overcome in my driving mechanics. I'd expect the car to go, then it didn't, then it would release the brakes suddenly, and VROOOOM!

That's what I thought at first, but now I like it. I don't know if I've gotten used to it, learned how to smooth it out, or if there's some kind of "break-in" process that smooths out its behavior.

Regardless of why, I can get the car rolling smoothly out of hill assist mode now.

I don't even notice it anymore. Thought I was going to hate it when I got my car a year ago. I feel like I can still roll backwards whenever I want (either wait out the two second delay or very lightly tap the gas to disengage) and have never felt it stopped me from getting started on any pitch incline. Seems to let me be able to drive a little lazier since I don't have to worry about somebody pulling up too close behind me or keep the gas and throttle balanced to stay stationary while I wait for an opening to pull out into.

Hate it ...gonna have to read up more on how to disable it...if you know how to drive a manual car correctly and it engages to assist when it disengages it causes almost a small launch from you giving the car gas and lifting the clutch to go...now I have to wait for it to disengage and then apply some gas
