Hill Climb Assist trouble?

[christianchevell]

http://auto.howstuffworks.com/car-dr...rt-control.htm this is a site which explains some of the different ways they get the system to work on various cars...here is fords explanation with its two second delay I hope this helps...frankly i always just used the right foot to go at a angle on the brake and gas at the same time if some jerk was on my ass on a steep hill at a stop, and hoped to burn out a little to show them hey there are still clutches in some cars.....lol

Frankly I wonder which way they activate it wether its with a mercury switch or with some sensor it would be nice to know how to disable it if desired by intent. I do not know which way the general went as you can tell there are different methods of engaging it according to how stuff works.

You can't turn it off in the Camaro that's just stupid… I hope your joking and it is somehow possible to turn it off. I know with my GT500 you have to go through elaborate steps to enable/disable it:

Disabling and Enabling the Hill Start Assist Feature

Your vehicle comes with hill start assist already enabled. If desired, you can disable the feature by following the procedure below.

The following procedure must be completed within 45 seconds or the process will have to be repeated. Begin this procedure with the ignition turned off. This procedure is for both disabling and enabling the hill start assist system.

1. Apply parking brake to make sure the vehicle is not moving.
2. Turn the ignition on.
3. Place the vehicle in neutral gear.
4. Slowly press and release the brake pedal five times – make sure the brake pedal is completely released each time.
5. Rotate the steering wheel at least one full turn to the right and return
the steering wheel to the original starting position.
6. Rotate the steering wheel at least one full turn to the left and return the steering wheel to the original starting position.
7. Slowly press and release the brake pedal five times – ensure the brake pedal is completely released each time.
When the procedure has been completed successfully the ABS icon in the instrument cluster will flash:
• three times indicating that the feature has been disabled. • twice indicating it has been enabled.

Once the feature is programmed as desired, it will remain in that mode until the above procedure is repeated.

I would suggest looking in the manual if you haven't yet because this is a stupid feature to have to deal with…..

My question was asked on the live stream with Al Oppenheiser about the hill assist. I asked if there was any way for it to be disabled and he said something like "Don't hold the brakes so long." So I'm not sure if it's something that can actually be disabled but then again it was asked on a live stream show so he probably wouldn't go into detail as to how to do it?

Even if it worked very well, it would still only be a crutch for those just learning to drive a manual transmission car. That's probably the manufacturers' justification for including it in the first place - so that drivers new to stick shifts won't be as intimidated by hill starts.

In that respect I suppose it's a good thing if it helps maintain manual transmissions as viable options.


But for cryin' out loud, Chevy, at least assume that even rank MT newbies will eventually catch on and not need this sort of 'help' the whole time they'll own one of your MT cars.


As cumbersome as Ford's method of disabling it goes, the good thing is that it becomes the new default setting. Other Ford default settings require similar procedures, and you don't have to worry about them again unless you actively want them changed (or at least not unless/until you have to replace the SJB, err, BCM).


It gets awfully easy to suspect that the people at the various car mfrs who have been pushing for these things don't have enough manual transmission driving experience to know that hill starts just aren't that tricky after you've been doing them for a little while.

Time was when you had to demonstrate having enough hill start skill to avoid stalling or rolling backward to your driver's license examiner.

One thing I will report about it in my Shelby is if you begin to let off the clutch it will still hold for about two seconds and then start to roll back. On my car, at least from what I can hear from the Camaro owners, is way less invasive than the method that GM uses….

Hopefully it can be disabled. Not giving a way to turn it off would be a huge oversight on GM's part.

I have a '13 ZL1 and can't seem to make HSA work. Not that I really care, but I was curious after reading this thread.

My position is that if you notice it at all, it's too invasive.

There are times when I actively want to have the ability to roll back slightly in the hope that whoever is right behind me might have to stop and think or wonder for a moment (and be a little less likely to come crawling up my car's tailpipe on my 1-2 upshift, which I'm not going to do in drag-race style solely for the benefit of traffic behind me).

What would be your response to a human right-seat passenger who insisted on pulling up on the P-brake for you every time you had to stop on a hill?

Out of the blue I got a call from GM engineering Saturday (!) asking how I liked my ZL-1 and if I had any problems. I told them about the hill assist and that it was the only problem. (I should have moaned about MyLink not recognizing portable hard drives, too, but I didn't discover this until today.)

They said 1) give the dealer a chance to fix it, 2) Call the 800 number listed in the owner's manual if the dealer couldn't help, and 3) the engineering team may call me back if I grant them permission (which I did).

This is the first car I've had where the manufacturer asked me how their product was performing. Pretty impressive.

All you have to do is stop on a steep enough hill, assuming you have a manual transmission, and take it out of gear. The DIC will alert you the "Hill start assist is active". Then, if you let go of the brake, you should notice the car won't roll backwards for a couple of seconds.

That's pretty easy for someone in FL to say!

I don't think anyone NEEDS it. Except maybe people in West Virginia or Colorado or San Francisco... It would be nice to have though.

Except I've only lived in FL for 2 years - I drove manuals in England for 10 years before that and have performed hundreds of hill starts on very steep hills before now without the need for any help.

In fact if you can't perform a hill start without rolling back in England then you won't even pass your driving test.

I would have no issue with the system being there if it could be turned off, but to force the system on those of us that can actually drive a manual properly is really annoying

[pharmboy]

ya, not gonna lie, the hill assist is annoying. It's probably the ONLY thing i don't like about my zl1. I find myself giving it gas and rolling back (and repeat) just to keep the hill assist from engaging. I did figure out that if you can time it just right, you can just gas it a little riiiight before the brakes disengage. But overall I could do without it. Truthfully, if you need a feature called "hill assist" in a manual vehicle, you probably shouldn't own one that has 600hp...just sayin.
