Electrically Heated Seats are standard equipment on this model. Each seat has a separate control switch (1) and
(2) located in the Center Console. Each seat has individual heating elements, one set within the seat cushion, and
the other within the seat back. The heated seat system features two heating stages. Each control switch (1) and (2)
contains 2 LED lights that indicate the heating stage the switch is in. Stage one (1 LED) is for normal heating
operation and stage two (2 LEDs) is for quick heat-up.

OPERATION

The Heated Seat System will operate only when the Ignition Switch is in the ACC or ON/RUN position. The Heated
Seat Module receives switched power through Fuse 1 and non-switched power through Fuse 24 in the Underhood
Accessory Fuse Block. Individual illuminated Heated Seat Switches control each seat and are designed as toggle
switches that return automatically to their original position after being pressed. The switches and control module for
the heated seats are consolidated into a block with other switches to form a Switch Group. Switch illumination is
provided through instrumentation lighting. The Heated Seat Control Module controls the differing electrical power
consumption requirements of the heated seats in each heating stage and heating time.

The heated seats are switched from heating stage two
to heating stage one automatically after 5 minutes and
completely switched off after approximately 30 minutes
of continuous operation. Heating stage one (1) is indi-
cated by a single LED being illuminated within the
switch and heating stage two (2) is indicated by two
LEDs being illuminated. If the battery voltage drops
below 11 volts, the heated seats are deactivated auto-
matically and are prevented from being activated
again until sufficient battery voltage is available. This
state is indicated by a flashing LED in the Heated
Seat Switch. The heated seat elements are bonded to
either the seat cushions or seat covers and are ser-
viced only with their respective assemblies.

DIAGNOSIS AND TESTING

Before testing the individual components of the Heated Seat System, ensure the battery is fully charged, then check
the following:

•

If the Heated Seat Switch LED indicators do not illuminate with the Ignition Switch in the ACC or ON/RUN
position and the switch pressed, check Fuse 1 and Fuse 24 in the Underhood Accessory Fuse Block. If OK,
see Heated Seat Electrical Diagnostics in this section. (Refer to 8 - ELECTRICAL/HEATED SEATS - SCHE-
MATICS AND DIAGRAMS). If not OK, repair the shorted circuit or component as required and replace the
fuse.

•

If the Heated Seat Switch LED indicators illuminate but the heating elements do not heat, inspect the heated
seat system harness connections for looseness or corrosion. Clean and tighten all the connections to ensure
proper circuit continuity and ground paths as necessary, then retest the system. For complete heated seat
diagnosis, see Heated Seat Diagnostics in this section. (Refer to 8 - ELECTRICAL/HEATED SEATS - SCHE-
MATICS AND DIAGRAMS).

Note: The Heated Seat System utilizes a unique low voltage cut-off feature. This feature deactivates the
power seat system anytime the available system voltage is below 11 volts. Be certain to check the vehicle
electrical system for proper operation anytime the heated seat system appears inoperable.
