Well, while starting the car, the airbag sign should light up for a few seconds and then go off, which should indicate that the airbag system is fine. BUT - thats not a guarantee that airbags are gonna deploy. The light only ensures you of the fact that the total airbag system is ok.

@blackasta
So in that case, the seatbelt light also lights up and goes off when you fasten the seatblet. Does it mean the seat belt is also working fine??

These kinda things are unpredictable. But IMO, seatbelts fail much less than the ABS or the airbags.

I guess the seatbelt sign is a reminder for the driver/passenger to fasten the seatbelt. I do not think it has anything to do with seatbelt/pretensioner functioning properly. On the other hand the airbag indicator light is directly related to checking that the airbag deployment system (accelerometers - ECU - Airbags) is on.

Airbags and seatbelts have been around for decades now. Almost every failure condition in these systems have been found and addressed. Stop worrying about these things and enjoy the drive.

Can you guys check that in your car and reply if it happens in your car seat belts too? If it does, then is the seat belt faulty? Or how else can we check? Is hand tugging the only way to check the seat belts?
I was in same dilemma, one month back, out of curiosity I asked the Service Manager and he showed me how it works by applying immediate jerk (same as mentioned by others). He explained, when somebody meets with accident there is sudden braking or sudden impact which gives the sudden force in forward direction, which results in locking (tightening) of seat belt.

If you can move your body at the same speed as when you tug the seat belt, then the seat belt will hold you from moving forward. It is practically not possible to move your body at the "Tug" speed. Try it and see.
