Heated seats
The heated seat system is available on both manual seats and electric seats. The electrical sub-system consists of
the following components:
l
Seat heater switches.
l
Seat heater elements.
l
Temperature control unit (if electric seats are fitted).
l
Temperature sensor (if electric seats are fitted).
l
Thermostat (if manual seats are fitted).
Seat heater switches
The seat heater switches supply an ignition feed to either the temperature control unit (vehicles with electric seats) or
directly to the seat heater elements (vehicles with manual seats). When a seat heater switch is operated, current flows
to the seat heater elements causing them to heat the seat.
The ignition feed comes from fuse 15 in the passenger compartment fuse box.
Seat heater elements
The seat heater elements are located in the seat cushion and squab. The cushion and squab heater elements are
wired in series. Total power consumption at 13.5 volts is approximately 115 Watts.
The cushion heater element has an input feed from the temperature control unit or heater switch and an output to the
squab heater element, which outputs to earth.
