I use the car on hills a lot and I am wondering how I am supposed to engage the downhill descent. The manual is oh so confusing and I would hate to mess up my transmission and drivetrain. I'd rather ask someone who's already tried it. I've tried it once but not sure what's supposed to happen. I engaged the low gear, pressed the button and the car started vibrating.

turn on DAC, put it in low range.

take your foot off the gas and brake, DAC will apply the brakes; probly the vibrating you felt.

Then scroll down to see Demo on Downhill Assist Control.

Yep, all the vibrating and clacking is just letting you know that the system is working. Stating the obvious, but remember not to touch any of the pedals while DAC is operating.

Just so you know, DAC is for offroad only. You don't need or want to use it on pavement.

Really ??. I remember there was a video on the lexus website (i think a year ago) that demo'ed DAC on pavement. I have DAC on my '04 but have never tried to use it

In late fall I used the downhill assist while driving down Mt. Washington in the White Mountains in NH in my '03 GX. The system was great. Hit the button, put it in 1st and I only used the brakes 2 or 3 times. The Ford in front of me was smoking like a barbacue. He had to pull over to let his brakes cool down. I will probably never use this feature again but for those of you who will, it works as advertised.

Did you also have to put truck in Low Range ??
