DescriptionThe front seats may be optionally fitted with a special heating system (consisting of two heater elements located in the cushion and squab): these heat the seat to ease the discomfort of entering a cold passenger compartment in very cold weather, e.g. when the car is left outside for long periods during winter.The heating device located on each seat consists of two resistors operated by a switch located on the side of the seat.Once a certain temperature is reached, the heating action is automatically suspended by a thermal contact inside the device. An LED indicates when the heater is on.The seat heating circuit is protected by a special fuse and is controlled by a relay. Both are located on the fuse and relay bracket in the boot, on the right.The seat heating operates only whe the key is turned to MAR.
Functional description The seat heating relay J62 controls the circuit in question. The coil of relay J62 is energized by the ignition-operated line (INT/A) of the relay R1 protected by the fuse F9 : both are contained in the junction unit B1 . The supply to the relay's contact comes directly from the battery from the specific fuse B20 . This supply reaches the switches located on the seats through the connection D70 B (left seat) and D71 B (right seat): when the switch on the seat is pressed, the resistors of the heaters in the right and left seats, connected in parallel, are supplied until a thermal contact in the heaters disconnects the resistors when the temperature exceeds a certain limit. An ignition-operated led (INT/A) - line protected by fuse F5 of the junction unit B1 - illuminates the switch.
