Actually it is intuitively obvious once you understand the Quest as well as most new vehicles have the second generation air bags whose deployment rely on the weight of the passenger. Also the consumer has been trained to believe these safety devices are always on. Meaning you and I have to do nothing. It makes perfect sense to have some type of indicator that shows this vital safety feature is not active. Similar to the ABS system. There is not light on when it is working properly. But bright ABS light will shine if something is wrong with the system. Also this is the case with most traction control systems. No light on when working properly. Shut off the traction control and it will tell.
 
Not sure why you don't understand this esp. when you mentioned that the seat belts work the same way. IF you have them buckled, you see nothing. If you don't have them buckled you see a bright light. Teh way Nissan has it set up seems perfectly logical to me. Let the driver know when the safety systems are off or inactive by shining a light.
 
Yes the light stays on at night but trust me with all the other lights on the Quest console, you barely notice that small light.

your explaination is consistent with my understanding, and what my vehicle does.
 
please if you re-read post 1128, I believe you will also conclude that the poster's car behavior does not support what you expect, and perhaps what your car does.

I agree with the other Quest owners on the air bag off light. It makes sense.
Normal situation = airbag on = NO warning light.
Abnormal situation = airbag OFF = YES warning light.
The airbag is off when the seat is registering as below weight or empty.

it's the "even empty" part I don't understand. if the seat is empty, what is the alert for? the alert is supposed to indicate that something below weight is in the seat and the system had de-activated the passenger airbag.
 
a light on the dash at night to alert you to a "normal" condition like the seat being empty is not intuitive. sure i'd learn to pay no attention to it also, but that is indicative of a bad alert system design (my opinion).
 
alerting systems are suppose to draw your attention to an anomoly (like the gas tank empty, the high-beams left on, the seatbelt not buckled, a door ajar...)

I understand your thought process better now. Don't necessarily agree with it but I do understand.
 
I think it all depends what we expect. The airbags are suppose to act automatcially without driver input or action. We are now condiditoned as drivers and passengers that the airbags are there when we need them. The light lets you know that the bags are inactive. Not the normal situation we are conditioned to expect. In other words an anomoly. Also what if for some reason you need your child to sit inthe front seat (i.e. need to haul something and both 2nd and 3rd row are folded), you now see all the time that the bag is inactive. If it were to flash and then go off, you might not see the flashing or forget it is inactive. Plus I am sure Nissan planned it this way to cover themselves in case of lawauit.
 
The more i think about it we are on the same wavelength (scary).

well, we could ask any honda owner, and we could probably ask any sienna owner and at least for the former (i know because i drive an odyssey), the light would be on when your child was in the front seat, to let you know the system has de-activated the airbag because the passenger is too light.
 
it also happens when I toss some stuff like my laptop bag on the seat.
 
it is off when my wife is in the seat or i'm in the seat or there is no one in the seat.
 
now then - how'd you like a light on in a vehicle for every seating position if it had an airbag, and the airbag was disabled at that position because no one was in the seat?
 
alerting systems are designed to draw your attention to the discrepant. the no one is in the seat condition isn't discrepant, its a normal situation. the abnormal situation is someone does not weigh enough to warrent the system enabling the bag.
 
any sienna owner reading the forum that can tell us how your van treats this case?

Prior to the passenger seat recall the air bag icon never came on. I suppose that was at least part of the reason for the recall. After the recall, the "air bag off" light remains on when no one is seated there as it appears is the way it is supposed to function.
 
However, when my wife (122 lb.) is seated in the front passenger seat, the light is also frequently on. We returned to the dealer who made some adjustment, but the light still comes on when my wife is seated there, just not as frequently. By deliberately pressing down on the seat the light will go out only later to come on again.
 
My understanding is that the air bag should be off only when a child weighing less than 50-55 lbs. is seated there. I would like to know if others have observed this air bag off problem for passengers weighing more than 55 lbs.
 
I plan to ask the dealer to have the seat replaced rather than try more adjustments.

i'd have the dealer fix this immediately. if your wife's weight isn't being sensed properly for the bag to be enabled, then she's not protected (obviously).
 
curious, does your manual tell you how the light is supposed to function?

Re: Air bag warning lights [user777] by vonbill3
Apr 07, 2005 (9:07 am)
There are 2 warning lights: One for the passenger front seat and one for the rest of the bags (Supplemental warning light). In my manual ( pages 1-29 and 1-30) the function explanation for the supplemental light is clear. There is no info at all concerning operation of the passenger bag.
 
The confusing info is that the manual states that the system needs servicing if the supplemental light remains on after 7 seconds; flashes intermittantly; does not come on at all. It's confusing because the light-on condition for the passenger bag means that all is well when no one is seated in the passenger seat. In other words, light-on has 2 interpretations in the Quest depending on which light is on. I agree with some of the postings that the light-on condition should be a warning and not that all is well. At a minimum this should be discussed in the manual.
 
As I stated, in my previous posting we will push to get the seat replaced. For just this one problem we have made 5 trips to the dealer.

TSP 04141: A fix for bad windshield washers by vonbill3
Apr 07, 2005 (12:34 pm)
It's taken 1-1/2 years but Nissan finally got around to providing a fix for the poor windshield washers some of us had to contend with on our 2004 models. Check out the Quest TSB 04141 at the Nissan help site. The TSB provides specific instructions to measure washer performance. Depending on results, a set of shims are available to improve performance. The shims are in 3 sizes depending on how bad or good the washers perform. If needed, the dealer will do the modification at no cost.
 
I had the work done and the washers are now almost acceptable. The fix includes a modification to the nozzle which making them spring loaded so I can tweek the mounting to get better performance.
