HELLO ALL

Just a quick question. When someone sits in the passenger seat it seems that the Airbag light on the dash flashes. This dose not occur all the time. I can stop the engine fire it up again and it would then go out. It never at any time flashes on when I am driving on my own.

IT ONLY WHEN I HAVE FRONT SEAT PASSENGER

Any help I would be grateful.

Are they wearing their seatbelt?

Sorry wrong Car

If the passenger shifts thier weight forwards or physically moves forward towards the dash then the sensor picks up that something is too close to the airbag for it to deploy.

 

[jamiewilson]

Really? Thought it was a simple weight on seat, seatbelt on airbag active. Where is the proximity sensor as it seems overly complex and begging for failure, what happens if the occupant stretches their arm out before an accident, does the airbag fail to deploy?

The XK8/R has proximity sensors mounted on the inside of the B pillar and in the roof console. Can't remember if there's one on the A pillar, too, but I've only had the car two and a half years.

 

[OLDJAGMAN]

Yes there are wearing the seatbelt at all times. Strange this but have to get it sorted.

 

[jamiewilson]

well never knew that. clever yet annoying technology it would seem.

There is a sensor on the A pillar, a sensor in the center console just above the touchscreen, & a sensor in the roof just behind the sunroof.
They are all occupancy sensors for the airbag system. Ultrasonic I believe...

Oldjagman, how heavy is your passenger? If they are the right weight they can confuse the system.
The airbag doesn't deploy if the weight in the seat is too low with the seatbelt in use. For example with children or skinny birds.

Well I got a right plump one that sits in the passengers seat and is always moving about and moaning that the seat belt is trying to strangle her (belt pretensioners) and this seems to keep triggering the airbag light on her side all the time. Wish I could just dart her and load her in the car....It would also be quieter too.

Have you tried a cg lock, nice item that keeps the tension adjusted without compromising safety.

 

[OLDJAGMAN]

I am not sure what a CG lock is. Can you enlighten me Thanks.
