Re: Adaptive cruise adjustment?

The day I picked up my GC Overland I used the ACC to drive for four hours and I found it to be smooth and it exceeded my expectations. It was set a little conservative on distance but I'm fine with that. I'm glad that I ordered it. As for cost, it is part of a package with cross path warning and blind spot warning. It is fairly reasonable for all three. All aspects work as well as I could have hoped. My young daughter loves the blind spot warning.

I wouldn't use it in stop and go or heavy traffic. Light traffic moving at 55+ is best.

Re: Adaptive cruise adjustment?

I did over 1000mi in mine with the ACC on 90% of the time. I found it a joy to use and only noticed that it did not like round-abouts, as the car in front would brake, so would the ACC, but it tended to over brake, then would try to catch up while I was turning in the round-about. While I know that it is best not used in this situation, I found I was more relaxed as the consistent speed changes when driving through different speed zones, did not concern me as it just matched the car in front.
I would want this feature on any future cars I purchase as it is a great option and well worth the money.

Re: Adaptive cruise adjustment?

This summer I drove extended distances on a variety of roads ranging from two lane to Interstate using the Adaptive Cruise Control. On long trips I found that it was a real pleasure and helped to cut down on the fatigue that one experiences when driving long distances on major highways. However, I find that I do not use the feature in city driving with heavy traffic. After reading the manual I believe that there is a difference between the collision warning system and the collision avoidance feature. They both require that the Adaptive Cruise Control be activated. However, the collision warning system does not require that a speed be set. I remember asking the Service Manager at the dealership about the difference between these two features shortly after taking delivery of my 2011 Jeep Grand Cherokee Overland. He confirmed the difference after consulting with Chrysler Canada.

Re: Adaptive cruise adjustment?

My FCW will go off without the ACC turned on, it seems to be always on.
I have had several false warnings, so I turned from far/close to only close setting and the false alarms have mostly gone away.

Re: Adaptive cruise adjustment?

Quick question:
When the ACC brakes do the brake lights come on too?
Also, I do love ACC I just get better MPG when I don't use it in moderate traffic

Re: Adaptive cruise adjustment?

Yes, the brake lights come on. Saw their reflection in the side view mirror the other night. Depending on how quick it needs to change your closing rate on the vehicle in front, it will also coast or "let up" without braking.

This is a great safety and fatigue-reducing feature when used in the correct situations.

Just my preference. The yellow triangle blind spot warnings are cool/helpful though.
Yeah, if you are always city driving or on congested roads, then there is not much use for the adaptive cruise. But, in more congested traffic, I've been saved a couple times by the collision avoidance feature when merging into traffic. As I peak over the shoulder to double check if the lane is clear or someone is bearing down, the car I'm following stops, the avoidance alarm brings my attention to the car in front in plenty of time to avoid a nasty experience.

The audible warning that something may be in my blind spot when the turn signal is activated is re-assuring.

These two features alone is worth the option cost, IMHO. But YMMV

If you were 17 feet behind me at 70 mph you would be getting the bird.

I love the ACC. I use it all the time on the highway. Just set it and forget it. I keep it on setting 3, leaving plenty of room for cut-ins. As soon as you hit the turn signal to change lanes, the vehicle begins to accelerate back to the set speed. I'm amazed that it doesn't react to large trucks in the next lane when going through a turn. I wonder if the steering wheel position has something to do with that?

Re: Adaptive cruise adjustment?

I noticed on a large roundabout (not sure what they are called in the US may be rotary)
With ACC on the other vehicle leaves the jeep keeps a constant speed until the steering wheel is straightened.

This is a big roundabout can do 60km/h around it.

Or maybe stability control!

Re: Adaptive cruise adjustment?

I didn't want the acc either but have found it to be indispensable after a few long trips. It's not perfect... But the fatigue from a rd trip was less than before. In traffic I'd rather not use it and stay more focused on driving.
