Seat Cushion: Description and Operation
HEATER-CUSHION PAD
DESCRIPTION
Vehicles equipped with the optional heated seat system have two, carbon fiber heated seat elements, located in each front seat. One heating element is
used for each seat cushion and another for each seat back.
Each of the heated seat elements consists of multiple heating circuits operating in parallel throughout the carbon fiber element. The heated seat elements
are captured between the leather trim cover and the seat cushion assembly. If a malfunction occurs in one or more of the individual carbon fiber circuits,
the others will continue to provide heat.
The heated seat elements cannot be repaired. If found to be damaged or inoperative, a new heating element assembly must be installed.
OPERATION
One end of the heated seat element is connected to ground at all times through a splice under the seat. Battery current is directed to the other end of the
heated seat element by the heated seat module. The heated seat module will energize the heated seat element when the heated seat switch is depressed in
the Low or High position.
As electrical current passes through the heated seat element, the resistance of the wire used in the element disperses some of the electrical current in the
form of heat. The heat produced by the heated seat element then radiates through the underside of the seat cushion and seat back trim covers, warming
the seat cover and its occupant.
