I was not in cruise control mode either. It was unexpected so I thought I'd mention it on here as that never happened in my 2012. Wasn't sure if it was a "feature". The warning has gone off before and NOT applied any brakes for me, but before the warning was short lived or I was already applying the breaks.

This time the warning was audible for two seconds or so (so a considerable amount of heads up), I didn't apply the breaks at all and as I got closer to the car ahead of me, there was like 3 hard pumps on the brakes and I had a wtf look on my face, but then was thinking that it was a nice safety feature.

Thats too funny! The exact same thing happen to me! The guy in front me was going into a small strip mall, and I didnt apply the brake, alarm went off, then car applied the brakes while my foot was over the gas pedal, but not applying gas. I jerked forward pretty hard since I didnt expect the car to suddenly apply the brakes. It actually scared me. I kept thinking, if I was drinking coffee or water, which I do quite often, it would have spilled all over my self. It was that hard of jerk.

the other day, same situation but this time the alarm sounded, and then my brake pedal shook sideways, but it didnt slowed the car.

Maybe I need to start breaking sooner! But I like the feature.

I drive a 2014 summit.

Re: Advanced Collision Warning Breaking?

I was in traffic rolling up to a car, no warning or stopping.

I was pulling up in a parking lot close to the car in front of me and nothing beeped or warned me.

What would be the safest way to test this feature?

Be sure not to have your foot on the brake because it will cancel-out the FCW.

Re: Advanced Collision Warning Breaking?

Actually, I was literally just reading the card that is attached to the gear shift when you buy a new JGC (at least it was on mine) and it says....

"When the system senses the driver applying the brakes to avoid a probable collision, additional brake force will be provided to the vehicle. When the system determines a collision with the vehicle in front of you is no longer probable, the warning message will be deactivated."

So I don't think, based on this, that having your foot on the brake will do anything but make the computer add more brake into it. Its all very confusing and I honestly don't understand why a company like Chrysler wouldn't have a bunch of youtube videos that go through all of this. I work for a software company and we put youtube videos out that go through just about every feature of every product we make. It would be good to hear straight from them how these things work, especially since I keep reading contrary stuff on here and in multiple places in the manuals, not to mention the sales rep and what he told me.

Re: Advanced Collision Warning Breaking?

The Advanced Collision Warning measures the car ahead of you stopping and you continuing to go forward, and then it triggers. So the safest scenario would probably be like I described with a car turning (they hit the breaks but are also turning) and you continuing on at your normal pace. Don't hit the brakes and the Jeep should take over with the warning and some brake being applied.

I wouldn't recommend trying to make it happen, just so you don't accidentally rear-end someone but I'm sure you'll find yourself in the scenario with someone braking / turning ahead of you and you know you wont hit them even if you speed up, etc

Re: Advanced Collision Warning Breaking?

wouldn't it be safer - if you wanted to test it - to see if you can tweak the detection distances? I know that with the active cruise control there are 3 distances that you can select. Maybe the same distance selector also interfaces with the collision avoidance and mitigation functions. And in doing so I suggest selecting the maximum detection distance.

In the UConnect settings menu there is a near and far setting for this exact reason, or you can turn off the braking part, or altogether turn off FCW.

Re: Advanced Collision Warning Breaking?

Good call, TitanFlyer.

Changing FCW And Active Braking Status
To change the FCW and Active Braking settings with
Uconnect® 8.4/8.4A System Screen — if equipped.
NOTE: The settings can only be changed when the
vehicle is in PARK.
Follow these steps to set the FCW and Active Braking:
1. Press the “Controls” soft-key located on the bottom of
the Uconnect® display.
2. Press the “Settings” soft-key.
3. Press the “Safety & Driving Assistance” soft-key.
4. Press the “FWD Collision Warning”, Far or Near
soft-key for your desired preference.
5. Press the “Active Braking” On or Off soft-key.
NOTE: A check mark will appear in the selection box to
indicate the setting.

To change the FCW and Active Braking settings with
Uconnect® 5.0 System Screen — if equipped.
NOTE: The settings can only be changed when the
vehicle is in PARK.
Follow these steps to set the FCW and Active Braking:
1. Press the “+ MORE” hard-key located on the lower
right side of the Uconnect® system.
2. Press the “Settings” soft-key.
3. Press the “Safety/Assistance” soft-key.
4. Press the first “FWD Collision W...” soft-key.
5. Press the “FWD Collision Warning” Far or Near
soft-key for your desired preference. Then press the
back arrow.
6. Press the second “FWD Collision W...” soft-key.
7. Press the “Active Braking” On or Off soft-key.

The default status of FCW is the “Far” setting and the
Active Braking is the “On” setting, this allows the system
to warn you of a possible collision with the vehicle in
front of you when you are farther away and it applies
limited braking. This gives you the most reaction time to
avoid a possible collision.
Changing the FCW status to the “Near” setting, allows
the system to warn you of a possible collision with the
vehicle in front of you when you are much closer. This
setting provides less reaction time than the “Far” setting,
which allows for a more dynamic driving experience.
NOTE:
• The system will retain the last setting selected by the
driver after ignition shut down.
• FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects not in the
path of the car, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.

Re: Advanced Collision Warning Breaking?

I wonder how this system will work with snow drifts. In almost every vehicle I have owned, at some point I have had to "hit" drifts that are about bumper height (or more) during winter driving. If a system like this applied the brakes I would end up stuck in the drift.

Cool system but all these systems need a disable button.

I know people with Toyota 4X4 that hate them and get stuck all the time due to traction control software not allowing the tire to spin and throw the snow/mud out of the tread. Toyota is a nanny and has no disable capability.

Yep, just turn it off.
