ML-320 Child Safety Seat

[SmithIns]

We have a child safety seat mounted in the 2000 ML-320 in the center rear position.

Center belt is lashed down tight to hold the seat in position as well as the tether over the back into the safety clip behind the seat.

Could this cause SRS light to come on from time to time. I'm not clear on how the seat sensors works or if there are seat sensors looking for body weight.

Can someone explain please.

Thanks
