For a detailed list of front seat serviceable parts, refer to Seat - Exploded View, Front in this section.

Driver Memory Seat

When equipped with the memory option, the seat is controlled by the Driver Seat Module (DSM).

The system contains the following serviceable components:

• DSM, mounted to the seat track
• Memory SET switch, located on the driver cushion side shield
• Power seat track
• Power recline motor
• Seat control switch

Heated Seat System

The system contains the following serviceable components:

• Seat heater mats located on the seat cushion and backrest
• Heated seat buttons, located on the Front Controls Interface Module (FCIM)
• HVAC module

Climate Controlled Seat System

The system contains the following serviceable components:

• Thermo-Electric Device (TED) and blower assembly, located within each front seat cushion and backrest
• Air filter attached to each TED and blower assembly (for cushion TED filter, turn to the left to remove) (backrest TED filter is not serviceable, but can be removed)
• Cushion and backrest foam pads
• Cushion and backrest trim covers
• Climate controlled seat buttons, located on the FDIM (touchscreen)
• Dual Climate Controlled Seat Module (DCSM), mounted to the bottom of the front passenger seat

Remote Start Climate Operation (if equipped)

The customer can select different climate control modes/preferences when the vehicle is started using the remote start feature. This can be accessed through the message center. For additional information on how to set the remote start preferences, refer to the Owner's Literature. When the driver seat and/or passenger seat is set to AUTO mode, the driver/passenger climate controlled seat activates in full heat mode when the outside temperature is less than 0ºC (32ºF) and full cool mode when outside temperature is greater than 27ºC (80ºF) any time the vehicle is started using the remote start feature. No climate controlled seat adjustments are recognized during remote start operation. When the ignition is cycled to the ON position after a remote start event, the climate-controlled seat switches off.

Power Recliner

The driver and passenger front seats are equipped with a backrest adjuster. The backrest adjustment switch is part of the seat control switch assembly. The recliner assembly is mounted to the seat backrest and cushion frame. The motor and shafts are mounted in the backrest frame.

Front Seat Track Motor

There are 3 front seat track motors present on power seat tracks. The horizontal (fore/aft) front seat track motor is the only seat track motor which can be serviced separately from the seat track assembly. All other seat track motors (front up/down, rear up/down) are serviced as part of the seat track assembly.

Front Seat Motor Cable

The horizontal (fore/aft) front seat track motor rotates 2 cables which drive each side of the seat track uniformly. The outboard (long) cable can be serviced separately from the horizontal front seat track motor.

Power Lumbar With Cushion and Backrest Massage (14-Way Seat)

NOTE: Allow a few seconds for any switched lumbar or massage selection to activate.

NOTE: Lumbar air bladder deflation is normal before starting backrest massage.

The system contains the following serviceable components:

• Power lumbar with massage assembly, attached to each front seat backrest
  • includes the lumbar control module, air pump, 3 inflatable air bladders and hoses
• Seat cushion massage assembly, attached to each front seat cushion
  • includes 4 inflatable air bladders and hoses
• Seat control switch, attached to the cushion side shield

Vehicles equipped with front power lumbar and massage may also be referred to as a multi-contour seat or 14-way seat. The seat control switch commands the system.

Seat Control Switch with Power Lumbar and Massage

1. Massage control button
2. Lumbar air bladder control button
3. Seat track control button
4. Recline control button

• Push button 1:
  • forward for cushion massage or rearward for backrest massage
  • either way to turn off the massage
• Push button 2:
  • up or down to select top, middle or bottom lumbar air bladder
  • forward to inflate or rearward to deflate a lumbar air bladder; hold the button until the desired pressure is reached (each bladder must be selected and inflated/deflated individually)
  • forward or rearward while the cushion or backrest massage is on and the massage will turn off
• Push button 3:
  • in any of 6 positions to adjust the seat track
• Push button 4:
  • forward or rearward to adjust the backrest

When massage is selected, one bladder at a time inflates and deflates in the backrest or cushion. The backrest and cushion massage cannot operate at the same time. Backrest or cushion massage times out after 20 minutes.

When the backrest massage is turned off, the lumbar control will default to the middle bladder. If unsure which bladder is being controlled, 2 pushes up or down will always select the top or bottom bladder. The lumbar bladders can hold pressure while the cushion massage is on. After turning the backrest massage off, the pressure in each of the lumbar bladders will automatically return to their previous pressures before the massage was turned on, as long as voltage and ground remain at the module. Lumbar pressures will automatically reset after temperature fluctuations or when the vehicle has been turned off for a while.

When the backrest or cushion massage is on and the engine is turned off, the system will turn off and the module will not bleed off pressure in the bladders that are inflated. When the vehicle is turned on again, the Electronic Control Unit (ECU) defaults to off and deflates all bladders that were being used in the previous massage cycle. If the backrest massage was on when the engine was turned off, the pressure in each of the lumbar bladders will automatically return to their previous pressures before the massage was turned on.

When the cushion massage is turned off with the seat control switch, the bladders will deflate. The cushion bladders cannot be selected to hold pressure individually like the backrest bladders.

Refer to the Owner's Literature for additional information.
