DESCRIPTION
Some customers may complain that their seat warmers or seat ventilation do not turn on when the engine is
restarted after being left on when turning off the engine. The logic has changed from previous Mazdas
where the seat warmers and seat ventilation automatically turned on when the engine was restarted.
NOTE: Customers in cold weather are more likely to complain about this if their vehicle is equipped with
Mazda Mobile Start (MMS) (not available on Mazda3 or CX-30) because the MMS accessory instructions
state the seat warmers WILL turn on when the engine is restarted. The same can happen in the hotter
weather with the seat ventilation. This information is incorrect for these vehicles. Both features will now
require a manual setting every time the vehicles are restarted after being turned off. Consult the vehicle’s
owner’s manual for more details on proper seat warmer/seat ventilation operation.
