DESCRIPTION
Individually controlled, electrically heated front
seats are available as a factory-installed option on
some DR models. Vehicles with this option can be
visually identified by the leather trim seats and two
separate heated seat switches mounted in the lower
center of the instrument panel. The heated seat sys-
tem allows the front seat driver and passenger to
select from two different levels of electrical seat heat-
ing, or no seat heating to suit their individual com-
fort requirements. The heated seat system for this
vehicle includes the following major components,
which are described in further detail later in this sec-
tion:
• Heated Seat Switches - Two heated seat
switches are used per vehicle. One switch is used for
each front seat. The switches are mounted in the
instrument panel, below the radio (Fig. 1). Each
switch also includes two Light-Emitting Diode (LED)
indicator lamps and an incandescent back lighting
bulb.
• Heated Seat Module - also referred to as the
Seat Heat Interface Module (SHIM), this module con-
tains the solid state electronic control and diagnostic
logic circuitry for the heated seat system. One heated
seat module is used per vehicle and is mounted
under the drivers front seat cushion (Fig. 1). Refer to
the Electronic Control Modules section of the service
manual for additional heated seat module informa-
tion.

• Heated Seat Elements - Four heated seat ele-
ments are used per vehicle. One element is used for
each front seat back and one element and sensor
assembly is used for each front seat cushion (Fig. 1).
The heating elements are integral to the individual
front seat and seat back cushions and cannot be
removed once installed at the factory. Replacement
seat heating elements are available, without having
to replace the entire seat cushion or trim cover. Refer
to the detailed procedure later in this section.
• Heated Seat Sensors - Two heated seat sen-
sors are used per vehicle. One heated seat tempera-
ture sensor is used for each front seat cushion. The
sensors are integral to the individual front seat cush-
ion heating elements (Fig. 1) and cannot be removed
once installed at the factory. Replacement seat heat-
ing elements with the sensors are available, without
having to replace the entire seat cushion or trim
cover. Refer to the detailed procedure later in this
section.
Following are general descriptions and operations
of the major components in the heated seat system.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the heated seat system. Refer to Wiring for the
location of complete heated seat system wiring dia-
grams.
