If the engine falls below 350 rpm while the cooled seats are on, the
feature will turn itself off and will need to be reactivated.
Note: When the heated/cooled front seat is active, you will be able to
hear the fan operating inside the seat. This is normal.
Heated and cooled seat air filter replacement (if equipped)
The climate controlled seat system includes air filters that must be
replaced periodically. Refer to Scheduled maintenance information.
The filters are located under each front seat and can be accessed from
the 2nd row foot-well area. Move the front seats all the way forward and
to the full up positions to ease access.
