The 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 in each seat
consists of two resistors operated by a switch located on the outside
of each seat.Once a certain temperature is reached, the
heating action is automatically cut off by a thermal contact inside
the device.An LED located in the actual switches indicates
when the resistors are switched on.The seat heating circuit is controlled by
two dedicated relays, located near the operating switches.The circuit is protected by a specific fuse
and operated by the services relay for the junction unit under the
dashboard: the power supply is available both with the ignition
ON and with the ignition OFF: during starting, this relay is temporarily
deactivated, whilst with the ignition OFF, the Body Computer keeps
the relay activated for 3 minutes, but deactivates it 30 seconds
after one of the doors is opened.
