How do you know it works fine?

 

I've been through this with 08' and yes the disable function is gone. There is no light and actually no electronics going into the passenger seat. Jeep went to a dual stage airbag in 08' and it appears scrapped the disable all together. Sorry I was not happy either. My manual says if you need to put a child or small adult in the front seat to move the seat as far back as possible, I guess the farthest seat setting must be out of the airbags range ?

 

Here's an excerpt from Saftey.com about airbags and children.

Keeping Safe With Airbags
While it is clear that airbags can be hazardous to children, a study by the Insurance Institute for Highway Safety found that use of proper restraints makes all the difference. A child seated in the upright position with a shoulder/lap belt, and as far away from the dashboard as possible, is in the safest position for a young passenger. This seating minimizes the risk of injury from airbag deployment.

It is critical for parents and caregivers to monitor their child's seating position. It may be difficult to safely seat young children in the front of the car due to their small size. For this reason, it is recommended that children under 13 always sit in the rear. Rear seats provide good restraint without the risk of airbag injury.

Changes in air bag design will also reduce hazards to children. Car manufacturers are developing 'smart' air bags. These devices monitor seat belt use, passenger size and proximity, and tailor the rate and force of deployment.

Until improved technology becomes available, however, the best protection for your child is either to use a correctly positioned seat belt or to make your child sit in the backseat. In this way, air bags may serve their original purpose: keeping passengers safe.

 

Mine seems to work as intended...just today, I had an item that weighs 24 lbs in the seat that disables the air bag...when the item is lifted the airbag is enabled. I have no problem with this...
