Just an observation (although not fully tested) that the auto stopping only happens when cruise is activated.

Has anyone with more patience read the manual or at least observed this?

If this is the case I am a bit disappointed as I was kind of thinking it would be good for stop and go traffic where I get distracted...

Now the cruise does adjust but it is abrupt on the throttle and less efficient.

Not sure I understand your question but I think you're talking about the smart cruise control feature where it will keep a set distance from the car in front of you. This feature is only active when the cruise control is engaged. Also, in the Niro the cruise control disengages at 6mph so it does not in fact, stop the car completely. This is evidently due to the lack of an electronic parking brake in the Niro, an minor disappointment in my opinion. It would be nice to have fully automated stop start in traffic.

When the cruise is not active there is still the front collision avoidance feature. Like the smart cruise control this feature is not active below 6mph. This is intended solely for emergency braking to avoid a collision, not for deliberate use in traffic. :eek:

The emergency autonomous braking works even when cruise control is off (as long as you have emergency autonomous braking turned on in the menu, which it should be by default).


You probably just didn't notice because you haven't nearly rear-ended anyone yet. It does NOT NOT NOT replace normal braking. It is designed to literally slam on the brakes (nearly screeching tires) at the last second before it's too late and the computer has decided you aren't going to react in time yourself.

In every other scenario, it does nothing, and lets you control the braking.


You'll usually get a "forward collision warning" chime and message for a moment, and the computer gives you a moment to react yourself, before it gives up waiting for you and hits the brakes itself.


You should never really experience emergency autonomous braking. It would only activate in scenarios where, without it, you probably would have rear-ended the car in front of you. Hopefully that isn't a common occurance - if it is, consider staying off your phone while you're driving :D

It is not the same thing as the (normal, non-emergency) automatic braking that occurs in smart cruise control mode.

The AEB feature is something of an enigma. If you read the complaints posted on the NHTSA web site, you'll find "NHTSA ID Number: 11099431" where someone complained that AEB did not protect them form a collision. On the other hand, evidently they survived the experience, and perhaps AEB contributed to that outcome. AEB disengages when your foot is on the brake pedal (which this particular person apparently did at some point, so perhaps AEB didn't even engage in their accident). There are several other limitations to AEB, not all of which seem to be clearly spelled out in the owner's manual. There is a link to a service manual (this documentation is not necessarily correct for recent models or the model in your country) that spells out certain additional limitations to the AEB system.


My take: I hope I never have the opportunity to discover if it even exists. If it does exist and that opportunity comes up for me, maybe it's time for me to reevaluate my approach to driving safely. This is clearly a last-resort, "you messed up", kind of safety feature, and it's clearly not perfect.

It saved my butt once already. It worked. It literally slammed on my brakes when I was coming up behind someone who was stopped somewhere they shouldn't have, and I was looking over at my blindspot at the time. Car beeped at me aggressively and when I turned my head back to see why, the car slammed on the brakes a split second before I would've anyways. Probably would've hit the guy if it didn't brake for me, and DEFINITELY would have hit the guy if the beeps didn't alert me to the stopped car ahead.


So I have actual first-hand knowledge that it does work. Maybe not in all scenarios, but it worked for me when it was supposed to, so I can't complain.


It was VERY aggressive braking, I can't stress that enough. It virtually locked my tires, I heard them screeching a bit. It is most definitely NOT a system you want to use frequently... keep it enabled, but avoid needing to use it at all costs, it is purely a last resort. Your neck and tire treads will thank me.

Did the car come to a complete stop? I've read that while AEB will operate as you describe, it won't come to a full stop in the Niro. That of course leads to a collision if the operator doesn't finalize the stop.

Evidently the BEV Niro has an electronic parking brake. This feature seems mandatory for full stop cruise control. Maybe ABS can't actuate the brakes below a certain speed?
Bingo on the electric parking brake! That is the stated reason why only the BEV can do full start stop.

You likely mean AEB, not ABS. ABS works at two miles an hour.

Once I realized the car was hitting the brakes for me, I hit the brake pedal myself, so I'm not sure if it would have come to a complete stop by itself or not.

In the AEB test video above, of course it failed. Firstly, cardboard isn't going to be detected by the radar. Secondly, AEB doesn't respond to objects that are stationary and have always been stationary, otherwise it would slam on the brakes any time you make a turn to avoid a parked car or tree. Instead, it tracks the moving car in front of you, and detects when it has slowed to a speed significantly slower than you're going.

So the test didn't fail, you were testing a scenario that the AEB system was designed to ignore.

The only real way to test it is to almost crash into a car that stops in front of you, and that's not a test I recommend trying.

Yes, in a perfect world, AEB would make a car uncrashable, while also never braking when you don't want it to. But AI isn't that good yet, even Tesla hasn't completely figured out how to make that work. So the system we have in our Niro's isn't perfect, but it's far better than nothing, IMO.

AEB has been tested several times on my car and if flawed, is certainly working! Usual scenario is car in front is turning. I see that it will clear the road before I arrive at turning point and so continue at same speed. AEB slams into action, even though it would be impossible to hit the turning car. This happens if a small portion of the turning car is still in my lane when I'm within twenty feet (guessing at distance).

It also starts beeping and at least once took action when I was changing lanes and it judged I was too close to the car in front. Again, no danger, so AEB has only been annoying so far.

If you check out the euroncap safety videos it appears to work without screeching and fanfare:

2:38 into video

https://www.euroncap.com/en/results/kia/niro/25042

It even works with a pedestrian! (Inflatable as well)

I have to try this out with our inflatable Snowman! What a hoot. Who would ha e thought a simple car would be this much entertainment!!

The pedestrian did not appear to be inflatable, and it was moving. All a bit strange as the Niro is not marketed in the US as having pedestrian detection as are more advanced cars from other manufacturers.

The car dummy that was set up certainly provided an optimal radar target similar to a semi that was center of the lane if it was metallic (didn't appear to be cardboard. I wouldn't want to try that myself, but all the posted Ioniq attempts on video seemed to fail at detecting a static obstacle.

My car easily detects a turning car that has mostly left the lane. But it never detects parked cars that are just as close to my path as a turning car. It also starts beeping when it thinks I'm going to fast braking for a stopped car at a light. I think it really depends on the strength of the radar signal and how fast that signal is increasing. A stopped car only one quarter in my lane does not trigger AEB warning.

Thanks for the video! :)

@yticolev, do you have front sensors on your LX with Tech options ? or only the small radar for the SCC.


in my SX, i have those 4 sensors that detects moving parts in front of me, and exemple. last week. was parkes backward in a grocery parking lot, parked cars on the left and on the right.. As i was on D to go forward, it beeped me and a person from my left walked in front of me.! and another time it was a car..BAM right in my face.! It does the same like the back system does. pretty cool..

my subaru’s eyesight system will bring you to a complete stop if cruise control is on. (the brake releases afterwards so you need to hit the pedal to keep from rolling forward. and if you don’t go when the car in front of you goes it will give you an alert to let you know that traffic is moving again.) the emergency brake is a pull up lever between the seats so i’m assuming it’s not electric.
