Passenger Seat Belt Warning Chime goes on even though there's no passenger.
 

I was cruising down beautiful West L.A. this afternoon, and a pleasant drive at that minus a guy in a late model M3 who was tailgating me on the 10E, and then add another douchebag in a late model Jag who almost rear ended me because when I gave him "the stare" as he passed me on my right he seemed to be showing off to his female friend to look cool I guess.

Why God? why are there so many douchebags driving? I guess having a brand new car with dealer advertisement plates still on has something to do with it pffft!!!

Anyways, having said that....while I was in the middle of my pleasant FR-S cruise I noticed that my Passenger NO SEAT BELT FASTENED Chime randomly went off, and I was like wtf?

So in order for me stop the annoying chime, I reached for the Passenger Seat Belt and just fastened it. Chiming Stopped. It's the first time it has ever happened.

Question: Other than taking it back to the dealer to have 'em check it.....What else should I do?

Was there anything on the seat? Mine does that occasionally if I have something in the seat.

Damm you da BOSS!!!
Had my wallet, garage door remote, keys, and some other crap.

Thank you!!!

Yup Same thing happened to me. No passenger yet the chime was going off. I lifted my cellphone from the seat and bam...no more chime or seatbelt light. The seat is really sensitive seems like. And to add to your douchbag encounters, same here. Had a corvette tailgate me for a good 3miles. What an ass. The other three lanes were clear as day.:thumbdown:

so when someone follows you on a particular lane you say they're an ass?

When there are no other cars on the road and that person is inches from my bumper yes they're an ass. I was looking for an address and he could have passed me but decided to ride me till i turned then he turned in the opposite direction. It was pointless.

The weight threshold is way too low. I think it's 1.5 kg or something. I don't know why they didn't make it something reasonable like 20kg.

i always thought those seats will activate the chime when the object is 40lbs or more. at least that's what it said in my Nissan Altima Coupe manual. I haven't gone in detail about the brz manual yet.

In my limited experience on these things, I believe it changes from model to model. My old Lexus seemed to have a much higher threshold. Never beeped at me for anything either. That was one of it's best (and only good) features :bellyroll:

AFAIK it's not related to weight per-se. Some people months ago suggested that it had to do with the frequency of your phone and that tripping it off when it's in the passenger seat.

For those times when it's a non-electronic item, you can make the seatbelt chime go nuts by placing the item towards the back of the seat (against the seat back). I believe it's something to do with this car having a more modern airbag system that factors for the passengers seating position. Anyone else recall something like this?

You typed it before I could. It is sensitive to electronics. Put you iPhone on the seat and it will go off. Put a half gallon of milk and it will not.

Ya, its not weight related so much as breaking the em field of the sensors....like electronic, metallic, or conductive devices such as cables will do.

You can put a whole case of water there and not set it off, but a cell phone charger cable, cell phone, RFID badge, and other such non sense will set it off.

Think about it like traffic loops in the road....the light knows to change because the em field that the loop creates is interrupted by vehicles.

This explains why my Uncle Jed
With the metal plate in his head
Always gets stuck on red!

:thanks: I'll be here all weekend. Don't forget to tip your waitresses.

Uncle Jed must have a head the size a smart car.

This was covered a long while back. Don't put electronics on the seat. The sensor isn't weight sensitive it's sensitive to electrical fields....like the one in my bum.

Like the others have said it's electrical. Plug your phone into the car charger and set it on the seat and it goes off; unplug the charger and it's all good again.

Its so sensitive to electrical fields that you can trigger it simply by placing your hand half an inch to an inch above the seat and never touch it...Did it driving down the freeway tonight...made me chuckle

My girlfriends 15lb dog doesn't make it go off... I should probably get it checked..

Its the survival of the douchest my friend. You should had slightly braked a bit and scare the living shit out of them. Worse case scenario they hit you, and in a tailgate incident, the tailgators almost always fucked. Happy douching!

Yes I noticed this as well and the dealer confirmed it.

passenger seatbelt chime
 

Happens to me every time I lay my cellphone on the seat, or maybe a light bag of something. Just googled "frs passenger seatbelt warning" to see what came up and here you all are! Mine stated about 2/3 months ago. Car is a 2013 with about 22500 miles on it. Did anyone ask their dealer?

Dealer fix:



Buckle belt.




...i told em "no" because it looks like #foreveralone and that i'm trying too hard. Dealer won't take me serious no more. :(


All jokes aside, just buckle it in.



It is irritating when my Ipod cable sets it off or even a damn empty water bottle. Not sure if passenger fart lingering will too.

:bonk::bonk::bonk::bonk::laughabove::iono:


So if it goes off alone......does that mean ghosts are around???!!!

As it says several times here it is not broken or an issue. The sensor is not a weight trigger it is an electrical field sensor. Anything electronic or dense enough will trigger it. The ovious answer is don't put such things on the seat.

My Seat Belt warning light doesn't come on but my Airbag light will sometimes, when I put my backpack or camera there. haha

That's good to know 😂 now I know why 2gallon milk makes beep nonstop.

As I said there is no "weight threshold" it is not activated by weight. Two gallons of milk set it off because it is a liquid and the field detects it not because of it's weight.

Hehe good to know. Thanks Tcoat, I didn't bother reading anything after the first few posts. :D

time to buckle that belt in boys

You can have the sensor disabled at the dealership. It's an ECU config option. I also had them turn off the Daytime Running Lights at the same time as it's just another config option.

Its a ghost bro. Your car is haunted bro.

our cars have very strangely tempered sensors for the passenger seat. At first I thought it was weight triggered... but I've once had 20 pounds worth of bags in the seat and nothing.. I then thing that it's heat sensored, I placed my charging phone on the seat and it would continue to go off.

Dude there is no mystery here!

Didn't read the thread all the way through... :bonk:

I guess I was late to the party.

Pretty common error when it comes to this subject.
Someplace on here there is a 400 post thread about it and approximately every 5th one says how the system works. Those are then immediately followed by 4 people wondering why their bag of cabbage/jug of milk/plugged in phone/dead hooker's severed head or what not weigh enough to set off the alarm.

Heh, my old piece of crap phone never tripped the sensor but my new one does.

Started to freak out when the chime came on, then recalled reading this thread.

Are you sure it ain't a ghost?. #ghostslivesmatter

l latch my seat belt(passenger) when i find myself putting my phone and other stuff on the front seat while driving so i dont have to deal with the sensor going crazy

Pick up a hitchhiker. Problem solved.

Damn! I better remember that sets it off. Thanks for the "heads"-up!
