Driver Seat Module - Memory Seat
The power driver seat, power outside rear view mirrors and power adjustable pedals are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option. The DSM is located on the driver seat track.

This system allows automatic positioning of the driver seat to 2 programmable positions.
- A power driver seat position can be stored at any time. The driver must move the seat to the desired position using the driver seat switch assembly. The driver must then depress the memory SET switch which activates the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out), the driver must select a memory position. Memory 1 is selected by depressing memory switch 1. Memory 2 is selected by depressing memory switch 2.
- If no memory switch input is received within the 5-second time limit, the operation is aborted and the memory seat position switch (set switch) LED is turned OFF. This also occurs if one of the following inputs is received during the 5-second programming limit:
- Driver seat control switch
- Memory seat position switch (set switch)
- Power adjustable pedal switch

A programmed seat position can only be recalled when the transmission selector is in PARK or NEUTRAL with the ignition switch in the RUN position. A position may be programmed at any time.

Easy Entry/Easy Exit
The driver power seat easy entry/easy exit feature can be enabled/disabled. Refer to Information Bus (Module Communications Network) or the owner's literature.

Heated Seats
This system allows independent seat electrical heating of each front seat on demand.

The components of the system are:
- the seat heater mats located in the seat cushion and backrest.
- the dual heated seat module located on the passenger seat track.
- the heated seat switches, located on the electronic automatic temperature control (EATC) module.
- temperature sensors, located in the seat cushion heater mats.

Climate Controlled Seats
The climate control seat system is able to heat and cool the front seats. Each climate controlled seat is operated by push-buttons on the EATC module located on the instrument panel. Each front seat temperature is then monitored and controlled by the dual climate control seat module (DCSM) located on the passenger front seat track.

The climate controlled seat system contains the following components:
- EATC module
- DCSM
- Thermo-electric device (TED) and blower assembly within each front seat cushion and backrest
- Air filter (attached to each TED and blower assembly)
- Cushion and backrest manifolds
- Cushion and backrest foam pads
- Cushion and backrest trim covers

Manual Lumbar
The manual front seat backrest lumbar is adjusted by a knob mounted on the side of the seat cushion side shield.

Power Lumbar
The driver seat has an electro-mechanical backrest pad adjuster. The lumbar switch adjustment is on the side of the seat cushion side shield and is part of the seat control switch.

Manual Recline
The manual recline can be adjusted by a handle mounted on the outboard side of the cushion side shield.

Manual recliners are only serviceable by installing a new backrest frame assembly.

Power Recline
The driver seat has an electro-mechanical backrest adjuster. The backrest adjustment switch is located on the side of the seat cushion side shield and is part of the seat control switch.

Power recliners are only serviceable by installing a new backrest frame assembly. However, the recliner motor can be serviced separately.

Seat Side Air Bags
The driver and passenger seat side air bags are attached to the seat backrest frame.

Occupant Classification Sensor (OCS) System
The OCS system is standard equipment on all front passenger seats. For diagnosing or servicing the OCS system, refer to Air Bag Systems.

Rear Seats
These seats are a 60/40 split folding backrest. The 60 percent has a fold down armrest and may be equipped with cup holders. Each backrest is held in place at the top with its own latch attached to the package tray sheet metal and a striker attached to each backrest frame. The rear seat backrest latch release handles are located in the luggage compartment.
