Summary
Due to a vehicle side logic change for the vehicles listed above, the seat warming and seat ventilation systems will no longer automatically turn on when the vehicle is started using the MMS accessory. Both features will now require a manual setting every time the vehicles are restarted after being turned off. Refer to the vehicle owner�s manual for more details on proper seat warmer/seat ventilation operation.
