Arrangement of elements
Review
Since 2007, cars have been equipped with a new seat system. The front seats are manually adjustable in the longitudinal plane and inclination. Some cars can be equipped with heated front seats. The front seat heating only works when the ignition is on.
The second row of seats is divided in a 60/40 ratio; these seats fold down to increase rear cargo space. Defender 110 estates are equipped with 2 forward-facing third row seats. The third row seats can be folded and stowed to increase rear cargo space. For more information on folding the seats, please refer to the Owner's Manual.
Operating principles
Heated front seats
When the ignition switch is set to position II (ignition on), power is supplied via the central fuse block (CJB) to the winding of the window lift relay. The ground loop of the relay winding is created by the left (LH) and right (RH) seat heating switches. When either switch is pressed, the relay is activated and supplies battery voltage to the heating elements of the corresponding seat. Both seats are equipped with 2 heating elements: 1 in the seat cushion and 1 in the backrest; they are connected in series.
The heating elements in the front seat cushions are equipped with a thermostat. When the temperature of the heating element in the seat cushion reaches 37±3°C, the thermostat stops supplying power to the heating elements in the cushion and seatback. When the temperature of the heating element in the seat cushion drops below 28±3°C, the thermostat resumes supplying power to both heating elements.
