DESCRIPTION AND OPERATION Heated front seats are a new feature for 2002MY and are available as part of a cold climate pack on Td5 engine
variants only. The heated seats system comprises, two latching switches, a seat relay and heater elements.
The latching switches are located in the fascia. Each switch individually controls its related seat heater elements.
Each switch contains a tell tale lamp to indicate when the seat heaters are active. There is no timer function for the
seat heater operation and the seat heaters will remain active for as long as the switch is latched in and the ignition
is in position II.
The seat heater relay is located in the passenger compartment fuse box and shares its supply and operation with
the front window lift system. The relay receives a permanent battery voltage supply via fusible links 1 and 3 in the
under seat fuse box and fuse 28 in the satellite fuse box. The relay coil is connected to the ignition switch via fuse
7 in the passenger compartment fuse box and an earth point. When the ignition switch is moved to position II, the
relay coil is energised and the contacts close. Power is supplied from the relay to each of the seat heater
switches.
The heater elements are fitted in the seat cushion and squab on the drivers and passenger front seats and are
wired in series. The wiring looms for the elements is long enough to allow the seat squab to be lifted for access to
the under seat fuse box or the storage bin/battery without straining the wiring. The centre seat, if fitted, does not
have heater elements.
The cushion element receives the feed from the switch and contains a thermostatically controlled switch. When
the element temperature reaches 37±3°C (98±3°F) the thermostat cuts the supply to the cushion and squab
elements for that seat. As the temperature of the element falls to 28±3°C (82±3°F), the thermostat will close the
switch contacts allowing power to flow to both elements causing them to heat up again. In this way the thermostat
maintains the cushion and squab element temperatures between the figures stated.

DESCRIPTION AND OPERATION Electric window lift is a new feature for 02MY. The electric windows are only available on the front driver and
passenger doors. Rear passenger doors retain the manual window lift regulator mechanism.
The window lift system comprises a window motor in each front door, two window lift switches located in the fascia
switch panel and a relay, located adjacent to the passenger compartment fusebox. The windows are only
operative when the ignition switch is in position II.
Each window lift motor is located in the door, behind the trim casing. The motor and regulator form a handed
assembly and are not available separately as serviceable items.
The window lift relay receives a permanent battery feed via fusible links 1 and 3 in the under seat fuse box. The
relay coil has one side connected to earth with the other side receiving a feed from the ignition switch position II.
When the ignition is in position II, the relay is energised and battery voltage is supplied to each of the window lift
switches. On vehicles with heated seats, the relay is shared with the heated seat circuit.
Each switch has two wires to its applicable motor. When the switch is operated in either the up or down position,
one wire is supplied with a feed and the other is connected to earth as applicable for the selection made.
Each motor has thermal cut-out protection. If the window reaches the top or bottom limit of its travel or an object
obstructs the window, the thermal cut-out will sense the increased load on the motor and cut the power supply to
the motor brush contacts.
The cut-out time is between 3.5 to 5.0 seconds, with a time to restart of between 1 to 10 seconds. These figures
are based on an ambient temperature of 20°C (68°F) and a voltage of 13.5V.
