RE: SRS/Airbag Light
We have the booster seat made for MB by Britax. In our case there is a sensor in the seat that looks for a signal from the device( a magnet) in the booster seat. When it sees that signal the SRS is automatically turned off for the front passenger area.
I know you are a long term member with tons of knowledge, but I am pretty sure that the Babysmart system is activated only by babyseats or booster seats that comply with the Babysmart system's electronics on board the truck in the seat's sensor. I looked at the wiring diagram on this a few years ago and it only showed the Babysmart sensor in a 99 ML 430. Nothing else in the circuit that would use weight as a means to shut off the SRS.
The Babysmart system is in many vehicles like BMW, Volvo, Saab and others. At stores that sell car seats or boosters it is very hard to find the Babysmart compliant seats, but they are out there.
Here is one tidbit of safety info on the system.
Now here is where the weight of a passenger comes into play on different "smart systems.
"Next is, don't put your kids in the front seat. Since the most common type of crash is frontal, the rear seat is the safest place for children to ride. A study by the Insurance Institute of Highway Safety (IIHS) showed that children under 13 are up to 36-percent less likely to die if they are seated in the rear seat. Despite this, an estimated one-third of children ride improperly restrained in the front seat. Front airbags don't protect children, either, because they were designed for adults. According to the National Safe Kids Campaign, 141 children have been killed by passenger airbags as of January 1, 2004. The federal government now requires auto manufacturers to begin phasing in "advanced," or third-generation, airbags that deactivate if the front passenger is too light. But this is intended more to protect smaller adults. So don't give in to the whining of your "I'm too big to sit in the back" kid." (source Edmunds.com)
