Seats: Description and Operation

SEATS

Front Seats

NOTE:
- The high speed controller area network (HS-CAN) circuits that pass through the passenger seat harness are part of the main HS-CAN LOOP. If the front passenger seat-to-floor connectors are disconnected, a NO START condition will result.
- The medium speed controller area network (MS-CAN) circuits that pass through the driver seat harness are part of the main MS-CAN LOOP. If the front driver seat-to-floor connectors are disconnected, various MS-CAN modules will not be able to communicate.

The front seats can be equipped with the following systems:
- Two-way manual seat track (passenger only)
- Four-way manual seat track (driver only)
- Six-way power seat track
- Manual recline
- Power recline
- Backrest, without fold flat
- Backrest with fold flat (optional, passenger only)
- Heated seats
- Heated/cooled climate controlled seats
- Memory driver seat
- Manual lumbar (driver only)
- Power lumbar
- Adjustable head restraints
- Seat side air bags (standard)
- Occupant classification sensor (OCS) system on passenger seat

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 on the seat cushion and backrest.
- the heated seat module located on the passenger power seat track and cushion frame on manual seat track.
- the heated seat switches, located on the electronic automatic temperature control (EATC) module.
- temperature sensors, located in the seat cushion heater mats.

A new heater mat will come assembled on a new foam pad.


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 electronic automatic temperature control (EATC) module located on the instrument panel. Each front seat temperature is then monitored and controlled by the climate control seat module (CCSM) located on the front passenger seat track.

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

Manual Lumbar
The front seat manual lumbar is adjusted by a handle 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.

Front Seats Without Backrest Fold Flat
Manual recliners on seats that do not fold flat are only serviceable by installing a new backrest frame assembly.

Passenger Seats With Backrest Fold Flat
Front passenger seats can come with a backrest that folds flat, when optioned with manual recline. The recliners on this backrest will recline the backrest back or fold the backrest forward. Pull up on the recliner handle allowing the backrest to recline forward. When the backrest reclines fully forward, if the recliner handle is held up, the backrest will continue to fold forward until it reaches the fold flat position. Manual recliners on seats that fold flat are serviced separately from the backrest frame assembly.

Power Recline
The front seats can come with 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 serviced separately from the backrest frame assembly. The recliner motor can also be serviced separately.

Rear Seats
The rear seats are a 60/40 split folding/reclining backrest design. The recliner release handle will allow the backrest to recline as well as fold the backrest forward. When the backrest is folded forward, the front legs of the seat will fold down (kneel) creating a level load floor with the luggage area. The 60 percent seat has a fold down armrest with cup holders. The armrest latches to a wire striker in the backrest frame.

The rear seats can be equipped with the following systems:
- Power fold backrests
- Heated seats

Do not remove the recliner-to-backrest frame bolts or the recliner-to-floor anchor assembly bolts. These parts are assembled on a fixture and if the bolts are removed and installed without a fixture, recliner binding or backrest latching/releasing failure can occur.

Power Fold Backrest
The optional power fold backrest, in addition to functioning with the manual recline handle, has a convenient power fold seat control switch mounted in the LH rear quarter trim panel rear hatch area. When the switch is pushed, left or right, an electro-mechanical motor releases that seat's recliners, through a cable attachment, and a spring load folds the backrest down and kneels the front legs. The seat backrest must then be manually lifted upright to the seating position with the recliners locked in place.

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

The components of this system are:
- the seat heater mats located on the seat cushion and backrest.
- the heated seat module located under the 60 percent seat.
- the heated seat switches, located in the LH and RH rear doors.
- temperature sensors, located in the seat cushion heater mats.

A new heater mat will come assembled on a new foam pad.
