SEATS

Front Seats
The front seats can be equipped with the following systems:
- Two-way manual seat track
- Four-way manual seat track
- 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
- Power lumbar
- Adjustable head restraints
- Seat side air bags (standard)
- Occupant classification sensor (OCS) system on passenger seat

Memory Recall - Remote Keyless Entry (RKE)
When the vehicle is equipped with a memory driver seat, the remote keyless entry (RKE) can be used with a key that includes an integrated keyhead transmitter (IKT). A personality or memory position for the driver seat and exterior rear view mirrors can be assigned to an IKT. Up to 2 personalities can be assigned, 1 per IKT. If the remote memory has been activated and that IKT has been assigned a personality, pushing the button to unlock the vehicle doors will recall the memory seat and exterior rear view mirror positions.

For information on diagnosing a RKE concern or associating an IKT to a memory position, refer to Locks.

Easy Entry/Easy Exit
The driver power seat easy entry/exit feature can be enabled/disabled using a scan tool. When enabled, the feature becomes a user accessible item on the message center allowing the user to turn the feature on and off. Refer to the Owner's Literature or Instrument Panel, Gauges and Warning Indicators for information on the message center.

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 HVAC 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 controlled seat system is able to heat and cool the front seats. Each climate controlled seat is operated by push-buttons on the HVAC 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 front passenger seat track.

The dual climate controlled seat system contains the following components:
- HVAC 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 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 can have an electromechanical 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 can 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 electromechanical 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

WARNING: Synchronize the seat recliners following the steps in the seat removal and installation procedure any time the seat is removed for service. The following actions may result in the loss of recliner synchronization that cannot be corrected and may cause the seat back to fail in a crash:
- Dropping the seat
- Sitting on the seat when removed
- Applying any load to the seat when removed
- Removing or loosening any recliner fasteners except for the safety belt buckle bolt

Install a new seat back frame assembly if the seat recliners cannot be synchronized. Failure to follow these instructions may result in serious personal injury to the vehicle occupant(s) in a crash.

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 striker in the backrest frame.

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

When the rear seats are removed from the vehicle, the inboard and outboard recliners must be synchronized before installing the seat back into the vehicle. If the recliners are not synchronized, carry out the synchronization steps in Seat - Rear, 40 Percent or Seat - Rear, 60 Percent. The recliners must not be moved from this synchronized position until all the seat-to-floor retainers are tightened to specification. Synchronizing the recliners may require the recliners to be released. Care must be used when working with the recliners as they are spring loaded and release with high force.

The 60 percent and 40 percent seat backrest frame assemblies include the backrest frame, anchor brackets and recliners (inboard and outboard). These parts must be serviced as an assembly. To prevent loss of recliner synchronization, recliner binding or backrest latch/release failure, the recliner bolts must never be loosened or removed, except for the safety belt buckle bolt. The backrest frame assemblies are assembled on a fixture not available for service.

The safety belt buckle bolt is the only bolt on either 40 or 60 percent seat recliner that may be removed for service. To service the safety belt buckle, refer to Seat Belt Systems.

Power Fold Down Backrest

NOTE: The smart junction box (SJB) may also be identified as the generic electronic module (GEM).

The optional power fold down 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 electromechanical 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 the 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.
