I can't help chiming in on this evil hill assist thread.

But first, I think that some people don't grasp the concept that most Subarus with Hill Assist have a mechanical system, which releases when the clutch is just about to be engaged, whether it has been brake locked for one second or one hour. Only the 2009+ STi's have an electronic version, which uses a timer, but makes it easy to disable this 'feature'.

My Forester has the mechanical system, which works reliably and precisly as designed to do. I do not need it, and I would much prefer if it did not exist. I can physically remove the system from the car, but I've decided that doing so would be more of a pita than living with it. And by the way, my biggest problem with it is that my garage is at the top of a steep driveway. Every day, as I back out of the driveway, I engage the clutch to roll out of the garage. Then, gravity takes over and I begin to roll down the hill. I immediately disengage the clutch since my speed quickly exceeds that which will ensure that I bottom out at the gutter. Gravity still speeds me up to the point that I must slightly brake the car. And here is the dig. Every time I apply the brake, the hill assist engages and totaly stops the car. So, I must re-engage the clutch 3 or 4 times just to safely roll to out to the street. This is a pita, and causes needless wear on the clutch.

Being able to deactivate the Hill Assist on the newer STi's is nice, but why on earth is the default position 'On'. I don't need (or want) the thing, so why must I turn it 'Off'? I can easily see that it has value for newer drivers, but imho, these drivers should have to turn it 'On', and they can deal with the indicator light. It's the same thing with my "Self-Dimming Rear View Mirror". I find this feature annoying any time except at night, on the highway, and yet I must disable it nearly every time I get into the car. Again imho, I think that it should be 'Off' by default, and turned 'On' by those who desire it. It came as part of a package or else I would not ever have had it in the car.

I'm done now. Thanks for listening......................Frank

Well... Then this "feature" was made for people like you... or...

1; It isn't working right in my car... cause it SUCKS...
2; It is working right in you guys cars... good for you...
3; It is working right in everyone's car and some people actually need it...
4; Nobody should actually need it... And if they do, then maybe they shouldn't be driving...

JMO... Been driving for almost 40 YEARS and in ALL those years have stalled a car/vehicle, maybe, 5 times, including learning to drive stick... This '09 STi I have probably stalled 15 times in the last year... Something is just not right with this system... Boo... Hiss... Subaru.

No offense Frank, but I don't believe the 2009 STI's are the only ones with a electronically controlled Hill Assist. As I recall when I look at my WRX 2008 transmission, there was no mechanical hill holder attached to it. On the older subarus there was a cable attached to your bell housing on the tranny that allows you to adjust your hill holder which you could disable by simply taking it off.

There isn't anything like that on the 2008 WRX. Not to mention there is a warning light on the dash when it's disabled which leads me to believe that it's electronically controlled. If your referring to the actual "brakes" as being mechanical then yes I would have to agree.

I personally hate the hill assist. I have to get my motor up to about 1.5-2k and then release the clutch only to watch it bolt forward and almost stall out. Makes me look like I can't drive a manual when I've been driving one since I was a young buck.

Yeah, the Incline Start Assist was introduced on the '08 Impreza.. all models... then the '09 Forester and then the '10 Legacy/Outback. The '09+ WRX and STI are the only cars that can have the ISA disabled. It's the same system in the '08.. but the controller doesn't have the software for switching it off.

The Hill Holder was a mechanical system that pre-dates ISA and was only on the Forester by '08 (?).

I believe only the STi does, my '10 WRX does not have the ability to disable ISA, at least to my knowledge....

I found the incline assist to be very handy when getting out of an uphill parking spot in one of the hilliest parts of San Francisco, with a car full of people, at night. No clutch killing needed thankfully.

I've come to realize that I can get around the hill start assist by not holding the brake pedal down too hard. mine only engages when I put the brake pedal down hard while stopping. Also if you shift to neutral while at a stop light this will disengage the hill start automatically as well. So now when I come to a stop I stay in neutral or switch to it as I stop or I just don't hit the brakes that hard as I come to a complete stop.

I've been trying to find a way to disable it without unplugging things in my WRX and that has come to no solution but in that time I have learned to work around it.

That is the whole point of this thread... We shouldn't have to Work around it... The people who need this feature should be the ones turning it on...

trust me, i completely agree with that statement but it's one of those things that for ow we just have to suck up and deal with unless we want to start hacking up wires and messing with other things.

There is a tilt sensor that is supposed to be in the system somewhere to help make the system engage more on hills, maybe if you find a way to make it read level all the time it wont engage the system nearly as much...

If you look closely, you'll see that it is for the WRX STI. If you didn't know, Subaru manuals are written generically....

This is taken directly from my 2010 WRX manual, see below:

while it is in there, it doesn't work. I tried 20 times to get it to work and it doesn't. It only works on STi models.

Why, yes it is... It's on my '09 STi too, and yes, I CAN turn it OFF... but why should I have a warning light on, my instrument panel all the time warning me that my hill assist is off????? It's BS... Cars manufactured for the dumb/uncoordinated that shouldn't be driving anyways...

EDIT; And for those of you that think the hill assist is the cat's meow... Maybe you shouldn't have a drivers licence.... Same as with all these other "helpers" that are coming out... Lane change beepers, automatic parking, automatic braking when too close to other car when catching up.... Sheesh get a cab if you actually need any of these "features'...

It ain't the cats meeow, but it is handy 'when needed', like traction or stability control, or ABS, or Airbags, or crumple zones.

Remember that in AWD cars like ours, it takes a little more energy(controlled) to get the entire drivetrain into motion.

I actually enjoy some of Subie's "low tech" nature, ascompared to all the gadgets and helpers in the Evo and GT-R. People drive them and are like "omg I can do anything in this car!" Yeah cuz the computers and mechanical devices are doing all the work bub.

It can be a slippery slope from a simple vehicle feature (drl's, hill assist) to replacing the driver (auto braking, self parking).

Well, it certainly IS a hindrance to me on my '09 STi... It DOESN'T come off with the clutch (it has a timer), It comes on even on flat ground when I stop fast and the car squats it thinks it's on a hill... It's just useless/stoop-id and frustrating to deal with. And yes I could turn it off but then there I sit, staring at this yellow warning light every-time I drive it...

You have the option to turn it off but complain about a warning light.... I agree it is stupid and silly, but if you really hate it that much, just get a different vehicle.....

Maybe a dealership could replace the tilt indicator. I believe a "could not replicate" would be the analysis...

2011 WRX and those instructions only apply to the STI. I really want to turn it off because I drive my buddy's truck fairly often and dont want to loose the practice of starting on a hill. Plus I like a manual transmission because of the extra work to get from A to B......

Really which I could turn it off permanently, but dont see how

I found the same information in section 7-41 & 7-42 of the 2011 Impreza Owners Manual.
It seems to be still only available for STI models even in 2011 which is too bad for people with other models that suffer with the HSA gremlin..
God knows i've stalled mine 3x so far and i've been doing hill starts for 25 years.

Yeah, same here- just bought a 2011 wrx and after driving my 2008 sti with the hill start assist disabled, I had forgotten how much I hated it. Stalled the WRX like 10 times already. Don't ask me how the hill start assist was disabled on my sti because someone helped me with it and I don't know what they did, but now I'm going to find out how to do the same on my WRX. Pretty sure Subaru knows a way, they just aren't telling us.

I have an 08 STI and would love to turn it off. I’ve been driving manual cars since 1997 and I don’t need it. I REALLY HATE IT when I stop on an incline so small that I don’t notice it, but the Hill Holder locks my brakes. Then when I start, I almost stall and look like a noob.
