HEATED SEATS - Description

Description

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.
