07 does not come with hill start assist. I think it first became an option on the 08's. To be honest, I would turn it off if I could. Just use the e-brake if you're not comfortable with hill starts yet

You can turn it off if you are not an 08 car, just fyi.

I hated that function so so much. Happy it was gone when I swapped in a 6 speed.

I love it. Why would you hate not rolling back on a hill?

My unfamiliarity with hill assist caused me to scratch my front bumper.
Was starting in reverse backing out of a spot on a downward incline.

But I still keep it on now that I have gotten used to it, very convenient.

2008 and newer Subies have it. I've used it a few times and it does take a bit of getting used to. You don't have to do anything to make it work, just be on an incline and start to roll backwards. The only thing I don't like is how it makes the car feel like its "stuck", almost like you rolled backwards into the thickest molasses ever. My car seems to take quite a bit of accelerator to roll out of hill assist. Can be kinda spooky if your in a line of cars on a hill. I prefer the e-brake method myself.

When my hill assist is on I do not roll backwards at all. Just give it a little gas when I let off the break and go.

It basically holds the car in place. On a hill, foot on clutch, take your foot off the brake and the car doesn't roll back at all? Does it just hold the brake on for you or does it slightly engage the clutch to keep the car from moving? I really want to try it now!

Keeps the brakes on for a second...if you wait long enough or take off it disengages....not sure if its rpm or just forward motion.

mine will not allow me to roll backwards for about 1.5 to 2 seconds at the most, then it rolls backwards. it just gives you a tiny bit of extra time to get moving forward. don't have to do anything to activate it, just have to be stopped on a hill for a couple seconds.

who cares? it's helpful, and not needed. but it's there, and passive.

you're so cool for rolling down a hill 1.5 seconds faster then I would, prior to putting any gas on it.

Only the STi as far as I know. I cannot turn it off in my 09 2.5i

haha i would be, except i know how to handle my car so i dont need an electronic nanny to do that for me. i can use the e-brake is the hill is super steep. if its not super steep, which is 90% of the time, i can go from the brake to the gas fast enough to barely roll a couple inches. if people behind me have a problem with that, they shouldnt come so close to my rear bumper. computers in performance cars were made for running the engine. THATS IT. electronic nannies that help you drive are for sissies and women and old people. if you talk on your cell phone while putting on your makeup, then yes you should probably be in some type of mercedes that will brake for you when there is a stopped car ahead of you. that makes me feel safer with those kinds of people on the road. if you need something to stop you from rolling backwards on a hill, then you should stop being distracted, start concentrating on DRIVING ONLY, and learn how to handle your machine so that you dont need electronics to help you. cars are becoming so damn boring it makes me sick. if i wanted a luxury experience id buy a mercedes. if i wanted sporty refinement then id buy a bmw. if i wanted raw performance then i'd probably buy something cheap and fast, or cheap with the potential to be faster without re-mortgaging the house. and i wouldnt want or expect it to come with the refinement and electronic nannies that the bmw and mercedes come with. /rant

Who cares? Well I care... The default setting should be off.. For those that want it, need it, then they can turn it on... It can be a MAJOR hindrance for those of us that learned how to drive a manual properly and are used to synchronizing the feet R & L for taking off without rolling back on a hill. Now after 40 years I have to re-learn to wait until the brakes come off over 1 seconds before taking off, it's very frustrating way to drive. And when instinct takes over sometimes ending out stalling... hugely embarrassing and totally frustrating... Boo SUBARU... BOO... And yes I know I can turn it off but then I have to keep looking at a warning light on the dash all the time... Boo....

For most hill assist systems, its mechanical, not electrical. MOST that is.

1. It DID come on some 07 models. My FXT had it. (I know, that isnt a WRX, but just saying the 07 MY, some had it)

2. It isn't something you can turn on and off. But it can be effectively disabled. (see first line)


3. Its MECHANICAL, not electrical. This is why you cant turn it off. There is no "off" You cant unplug it, you cant switch it off. You can adjust it so loose that it doesnt work any more.

4. It has nothing to do with your transmission. Its not part of the transmission. You can have it on a 6 speed. If you swap in a 6mt and its gone, you somehow disabled it (possibly just left it off). I know this for a fact, and as proof, well, I have a 6MT and, hill assist.





It isn't some thing you can change a setting. Its a VERY simple device. When you hit the brake pedal and the clutch, it engages a small valve, that holds the brake pressure in the lines until you release the clutch. This is normally fine and not a problem, but Subaru has a HUGE tendency to ship them from the factory with it adjusted so tightly that it engages on flat ground. If you adjust it properly, its seemless and damn near impossible to detect unless you are really looking for it. It will drop off as soon as you start to lift off the clutch even the tiniest bit on a hill, so your footwork is exactly the same as it would be without hill assist. The only difference is, when you are sitting still you don't have to hold your brake.





NOW<

For those of you with electrical assist.

USUALLY you can disable it without kicking any lights on by adjusting it looser. Be it electronic or pure mechanical, the valve is still a valve, and almost always adjustable. If you just adjust it looser, it will be less, or loose enough and it just wont function. Lights don't come on until you unplug things typically.





Are you guys SURE its electronic on your cars? I highly doubt it. If so, regardless, find the adjustment and loosen it at the valve itself. Its usually near the firewall by the drivers side frame rail.
