Default Disabling hill assist 2015 WRX

Has anyone successfully disable the hill assist feature in a 2015 WRX? I've tried a few times, following the directions in the manual, with no luck. The process fails at a particular point. More specifically, the traction control lights are all supposed to go out at some point (while holding the VDC off button) and this simply doesn't happen for me.

Anyone that has tried or accomplished this have any tips?

Thanks.

If it's something that's supposed to take place per the manual and it isn't working... talk with your dealer.

That is the plan if no one here is able to help. I thought someone here may have a solution.

Just curious, why is this such a concern for you? I assume this feature works just like my '13, and I guess I have a hard time understanding why it would want to be disabled.

I agree that the hill assist is a pain in the rear. I know how to drive a manual, I don't need help on hills. On my 13 it seems like the hill assist holds on just a tad too long at times making starts difficult.

If its anything like the GR models, it shows the instructions in the manual, but also has a "*For Sti Models" annotation, which means its not valid for you.

http://techinfo.subaru.com/proxy/695...5M1113A_15.pdf Section 7-42. Yes, this is not the same as your model, but will be similar.

I agree, and have been driving a manual for 18 years, but I still don't find the feature annoying or difficult to use. To each their own though I guess.

The directions are similar for the 2015, however, the manual does not state "For STI models" which lead me to believe it is valid for the WRX.

Default Yes!

Yes, I just did it now on a 2015 WRX. I followed the instructions in the manual and it worked. One thing to note is that the manual says to hold down the VDC OFF button until the VDC OFF light goes away. This took over 20 seconds to occur. I then released the button and quickly pushed it again. The "Hill Assist Disabled" light came on for a second and went away. I then turned the car off and turned it back on. The "Hill Assist Disabled" light came on and stayed on. I tested it out on a hill. It's definitely off.

yeah I did it too, then I turned it right back on because the car is so fat, turning off hill hold is just going to hurt clutch life unless you never see hills during your driving

The first time I attempted turning the Hill Assist OFF, I failed… I didn't hold the "Vehicle Dynamics Control Hold OFF" button long enough because I was impatient. Turned the car off, back on, and held the button for a pretty long time until the light turned off as the instructions advised. Maybe you need to hold it for longer?

I disabled it this past week, what a much better feeling while shifting, especially to 1st!

"...a braking effect may be felt even after the brake pedal has been released." - per 2015 WRX/STI Manual.

When you normally let off the clutch on 1st (with hill assist ON), you feel a slight pull-back of a brake-feeling. I always tried to smooth out my foot motions thinking I missed the catch point, but only slightly…

After turning it off, it makes shifting gears MUCH SMOOTHER. I realized that I never missed the catch point, it was the pull-back E-brake feeling from the Hill Assist!

Now, with more confident shift-feels with the later gears, I would recommend it turning it off for any owner!! (unless you drive on constant slopes, I could see how it would be nice).

Hill hold shouldn't be effecting your shifting in later gears, it only activates when you step on the clutch and brake at the same time.

I got it to work, just follow the directions, I turned it right back on though because it leaves an annoying light on and the car being so heavy and awd is annoying to do hill starts with.

The feature is a little annoying. I do enjoy it on the times when I'm on a very steep hill and someone is right behind me. I wouldn't have any problems normally but it is nice to take the effort out of it.

However, the other 95% of the time it's almost like a random launch control. Sometimes on even the smallest inclines I expect to take off but hill assist kicks in. In those scenarios it just seems too intrusive. They should have also made it a button in the WRX to toggle just as the STI is.

Is it just a button on the STi? Where is it located in the STi?

It's not just a button, you have to follow the procedure in the manual. I hated the hill-assist as well. I disabled it very early on in ownership..

I'm only a second class citizen so I wouldn't know for sure.

However I recall reading a thread asking the same question (for previous years) and the STi users said you could disable it but in the WRX it was forced on. They didn't mention how to disable it but I would imagine it's just a button like TCS. I think my WRX even has a cutout beside the TCS which they probably use in the STI.

Edit: ahh sorta like what I said:

Every car I've owned since 1983 has been a manual. I love driving manuals and can only think of one reason to shut off hill assist; so you can smugly say in conversation, "Oh, I turned that feature off".

I agree, I think its like a cocky thing, guys want to roll back on purpose so everyone can see they are driving stick and to make them sound like skilled drivers on the interwebz. You just feather the clutch like any other car

Nothing like thatů As a newer driver, it's much easier to learn the clutch with the Hill Assist feature OFF. Now driving is much smoother.
