Your opinion of Hill Descent Control?

I used it briefly yesterday on our new Trailhawk and it seemed to work really well. I wonder though about prolonged use in long, steep downhill sections. I assume it was designed with just that in mind but is it possible to overuse it and subject the brakes to overheating or fade? What has your experience been?

Re: Your opinion of Hill Descent Control?

Since it is only for use in off road situations, most people will not over use it.

Re: Your opinion of Hill Descent Control?

I have used it in off-road situations and love it! I don't worry about overuse or brake fade since it is not used like I see some folks use their brakes coming down on mountain road or those two-footers doing 80 mph.

Cheers,

Re: Your opinion of Hill Descent Control?

I got a chance to use it on the Leadville side Mosquito Pass and it worked very well. There was no brake fade whatsoever. It was great to have the control over the speed by using the shifter. As a relatively inexperienced off-roader it was nice to have.

Re: Your opinion of Hill Descent Control?

How is HDC different/better than using a low gear, in 4LO? Is it even slower? As I understand it, it's kind of the anti- anti-lock brakes, using the same mechanism but to slow the wheel down rather than free it up (as in a skid).

Based on my brief experience yesterday and for this particular vehicle, 1st gear in 4LO is insufficient on trails with steep, rocky grades. So in that sense, yes, HDC is slower and offers good control during the descent. I would prefer to have a lower gear ratio and control it that way but this seems like a reasonable alternative.

Re: Your opinion of Hill Descent Control?

The HDC is amazing. It is ONLY available in LOW gear. I have used it in serious off-road and it is amazing for newbies like me and probably useful to off-roading vets. The HDC has to be engaged by the driver.

No...it is NOT simply slower. It is snail paced - but surefooted. I would not worry about brake fade because you can really only engage it from either stationary or very slow to start with and the brakes don't have to slow down a fast moving vehicle but rather to creep forward a car that was hardly moving to begin with.

On the other hand the Uphill Ascent Control is fully automatic and you don't realuize it until you get the message on the dashboard screen and you realize that your uphill progress is unrelated to how much you mesh the throttle.

Re: Your opinion of Hill Descent Control?

I've used the HDC numerous times on trails in Arizona. It's especially handy when you are on rougher downhill terrain and your foot might get bounced off of the break pedal otherwise.

Re: Your opinion of Hill Descent Control?

you must first enable it on the appropriate box in the uconnect menu. To have it activated, you must be in 4-LO and be in an uphill situation. The car would know it automatically when to engage it.

Re: Your opinion of Hill Descent Control?

I think the HDC is outstanding. We used it a lot when descending steep snow covered trails in Ouray / Silverton, Colorado area. With the HDC on and the autostick in 1st gear I don't think I could walk down the trail any slower than the GC was going. In 1st it will go no faster than 1mph, 2nd gear 2mpg and so on through 4th. Always felt very sure-footed.

My trail only Jeep Scrambler with 4:88 gears, 4:1 low range and (can't remember 1st gear tranny ratio off the top of my head but low) will not descend as slow as the GC.

Re: Your opinion of Hill Descent Control?

Same experience as everyone else - it works great. I used it this weekend on Aspen Mountain coming down into town. I was already in 4-LO and using, then we stopped at one point and I took it out of 4-LO.

Continued down the hill in regular 4wd and it was immediately noticeable just how quickly you start gaining speed with HDC.
