Hill Assist Control dropped for 2013

Most of the 4.3 RAV4's came with the Hill Assist Control feature. If stopped at a traffic light on a hill, you could push the brake pedal hard until a beep was heard, then the brakes would stay on for 3 seconds while moving your foot from the brake pedal to the accelerator. This would prevent the vehicle from rolling backward. Toyota must have deemed it too confusing or too expensive, so they dropped it for 2013. Here is the new procedure from the 2013 owner's manual:

The new Hill Start Assist:

Starting off on a steep uphill

1. Make sure that the parking brake is set and shift the shift lever to D.
2. Gently depress the accelerator pedal.
3. Release the parking brake.

Brilliant!

James

Nice feature lost.

Found out my Accord has the feature yesterday and did it automatically. I pulled up into a steep driveway to turn around. Stopped and took my foot off the brake. The car didn't move and didn't go into its normal Auto Stop either. Giving a little gas pulled it up some more but it held there again until I shifted into Neutral. Pretty neat.

Guess it must have been our LED brake lights that held our 4.3s on a hill.

My automatic 2005 Mazda 6 v6 FWD never backed up when stopped up a hill.
My RAV always starts backing up if I leave the brakes on that same steep hill.
I was taken by surprise the first time I drove the RAV there.

May be it is for better fuel efficiency?

That's why it beeps.. I though it beeps because lack of brake pressure or what it is, like in old Land Cruiser when I pressed pedal many times the brake warning light came on.

But to my mind hill assist control is most useful with manual gearbox. Otherwise if you don't want use the parking brake it is quite a play with all three pedals. So I must check if 06 manual has this hac(checked, does not have).

Anyway like in other thread I said, Euro versions will come with hac and some with dac. To add these functions the Ecu must have control of brake pressure.
If Usspec cruise control has control of brakes when deaccelerating, it may be possible to add these functions.

When I drove a manual, on a steep hill, I would use the e-brake process. As for the Rav4 rolling back on a hill when the Mazda6 didn't, could be due to the fact the Rav4 is much heavier. My Mazda6 was a manual so I don't know how well the autobox held the car on a hill though.

I think Subaru's hill start assist is automatically activated with a ball inside the brake line or something that when you exceed a certain % incline, the ball will roll back and block the brake line holding the brake pressure for you until you gas it.

Don't know why the 4.3's had such a complicated system that requires you to press the brake harder to activate it.

However, I guess it's to not give you any surprises, cause on my Kia, the hill start activates automatically, but I would never know until I release the brake whether the hill gradient was high enough to activate the system, so maybe that's why the Rav4 Hill start assist is user activated.

It's because the Mazda is a lighter vehicle and maybe also the rpm's where a little higher at idle than the Rav4.

I learned to drive an old VW bus in San Francisco. You master the clutch and gas or roll into the people behind you. Some hills are so steep that I saw nothing but sky.

About the HAC - My lady found it difficult to press the brake hard enough to set it on.
