I checked in my friends car these lights are ON all the time when seat not occupied
Thanks
you either have it turned off (as it states) or you have a faulty sensor , if they are staying on when your driving .
they will come on when you start the car as it does a systems check.
and understand the car checks for weight in the seat to detect a person, if its below a certain amount but above zero, it will disable as it thinks its a child etc..
all models are different but to be honest i dont understand what your even asking anymore because your now talking about another car and you say it goes off when u drive etc etc
the photo you attached “clearly” shows the airbag as OFF

Yep sorry have not been very clear
I used to have the Airbag OFF light on all the time when driving and with no passenger. Then when an adult was sitting the light went off.
Now, when driving I have no lights at all with or without passenger. Just when starting the car all lights are on and in 2 secs they go off

my car c63s coupe same as my friend´s ..
Hope its clerarer now
Many thanks!
ok , so normal mod typically is, if no passenger or low weight in seat the light for airbag will lighten to show airbag is OFF. ( on center dashboard ) like in the pic.
if the seat is empty and your driving and that light is NOT illuminated , you have 1) either turned it off 2) have a faulty switch in the seat for the detection , those are my few cents worth of knowledge.
did you put anything heavy in the passenger seat ? etc ?

Ok, yes that make sense
How could it actually been turned off? Do not remember doing anything that could cause that.Also nothing heavy on passenger seat as I recall
My main worry is that passenger airbag is not working so not ready to deploy...

from mb,
now its possible the switch is in the glove box or someplace if yours has it.
Safety ranks among the core values of the Mercedes-Benz brand, which once again takes the lead by pioneering a host of innovative developments. One such development is the adaptive front-passenger airbag in the new C-Class.
The front passenger seat can be fitted with automatic child seat recognition, which dispenses with the existing transponder and instead works with a weight mat. This enables any child seat to be used. The airbag is automatically deactivated in this case and reactivated once the child seat has been removed. Mercedes-Benz is setting new standards with this system. Unlike systems offered by competitors, which often use a key switch to deactivate the airbag, this system prevents the user from operating the airbag incorrectly. Users often forget to manually activate the front passenger airbag when removing the child seat. In the event of an accident this can place adult occupants in considerable danger since the front passenger airbag and the seat belts work in tandem and can only achieve the necessary protective effect for adults by operating together. The system presented here prevents this by automatically activating the front passenger airbag when the child seat is removed.

Self-test of automatic front passenger front airbag shutoff
When the ignition is switched on, a self-test is performed during which the two PASSENGER AIR BAG ON and OFF indicator lamps light up simultaneously.
The status of the front passenger front airbag is displayed after the self-test:
PASSENGER AIR BAG ON lights up for 60 seconds, subsequently both indicator lamps are off (PASSENGER AIR BAG ON and OFF): the front passenger front airbag is able to deploy in the event of an accident.
PASSENGER AIR BAG OFF lights up continuously: the front passenger front airbag is disabled.It will then not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front passenger front airbag. The PASSENGER AIR BAG OFF indicator lamp may be lit continuously or be off.

Thanks
Your friend definitely needs to have this checked. The warning lamp to the right of the AIRBAG OFF light is the restraint system warning lamp. If that is lit, it indicates an issue with the restraining system. The airbag status and functions are all explained in the owner's manual with several consideration regarding child seats and stature of adults.

Thanks superwiss
So conclusion is all lights must be off when driving, no matter if an adult is seating on passenger seat or not
Lights just will lit for a moment when starting the car

No, that's not quite correct. The OFF should be lit if there is no adult sitting in the passenger seat and OFF should not be lit if there is an adult in the passenger seat. If OFF is lit, that means the passenger airbag won't deploy in case of a collision.

Also, consideration needs to be given to small stature adults like my wife who is a tiny Asian woman. At least some of my past cars had trouble deciding if she's an adult or a child . They recommend that if you have a small stature adult in the passenger seat and OFF is not lit, meaning the airbag will deploy that they move the seat as far back as possible to avoid potentially getting injured by the airbag explosion.

Haha yep I read about that
In my case the strange thing is Airbag OFF light is always off, even without adult in the seat...

Sorry, I take back what I said above. I just checked it out in my car. I've never really paid close attention to this and the owner's manual is clearly confusing, but the way it works in your friend's car is correct. Those lights stay on if there is nobody in the passenger seat. I tried to buckle the passenger seat belt, but that doesn't make a difference and I didn't have anybody handy to play passenger, but I'm assuming the appropriate lights will go out once somebody actually sits in the passenger seat and buckles the seat belt. I'm pretty sure if an adult sits in my car then all the lights go off. I took a quick video of the startup sequence. There's one light that goes off after the self-check, but the remaining ones stay on if there is nobody in the seat.

I assume if something was wrong I would get a passenger airbag error on the display?
Not necessarily. If the weight sensor is malfunction it might just think somebody is sitting there when in fact nobody is. That's what appears to be happening in your car. I would definitely have it checked out, because if the OFF light goes out, it means the airbag will deploy in case of an accident.

Yes, pretty sure is the weight sensor. But my main worry is airbag not deploying in case of accident...
