Front Seats - Overview: Overview

Driver Power Memory Seat 

The power driver seat is controlled by the DSM. The DSM is located on the driver seat track. PMI is required when a new DSM is installed. The DSM hard stop/soft stops must be set/reset any time a new DSM, driver seat track or driver seat backrest is installed. This system allows automatic positioning of the driver seat to 1 of 3 programmable positions. For information on programming memory positions or recalling a stored memory position, refer to the Owner's Literature.

The driver power seat is equipped with the following motors:

• Front height motor (serviced with seat track assembly)
• Rear height motor (serviced with seat track assembly)
• Horizontal motor (serviced separately from the seat track assembly)
• Recliner motor (serviced with seat backrest assembly)
• Lumbar motor (serviced with power lumbar assembly)

Passenger Power Seat - Without Redundant Seat Control Switches 

The seat control switch contains normally closed contacts which are grounded. An individual circuit is switched to voltage when a specific adjustment position is selected. The seat control switch is hard-wired directly to the applicable seat motors. The motor direction is determined by the polarity of voltage supplied from the seat control switch.

The 10-way passenger power seat is equipped with the following motors:

• Front height motor (serviced with seat track assembly)
• Rear height motor (serviced with seat track assembly)
• Horizontal motor (serviced separately from the seat track assembly)
• Recliner motor (serviced with seat backrest assembly)
• Lumbar motor (serviced with power lumbar assembly)

Passenger Power Seat - With Redundant Seat Control Switches 

The seat control switch contains normally closed contacts which are grounded. An individual circuit is switched to voltage when a specific adjustment position is selected. The seat control switch is hard-wired directly to the seat motors. The motor direction is determined by the polarity of voltage supplied from the seat control switch.

The driver or rear seat passenger(s) can position the passenger front seat forward/backward and also adjust the recline position by using the redundant seat control switches located on the inboard side of the passenger seat backrest. The redundant seat control switches are hard-wired directly to the seat control switch to operate the horizontal and recliner motors.

The 10-way passenger power seat is equipped with the following motors:

• Front height motor (serviced with seat track assembly)
• Rear height motor (serviced with seat track assembly)
• Horizontal motor (serviced separately from the seat track assembly)
• Recliner motor (serviced with seat backrest assembly)
• Lumbar motor (serviced with power lumbar assembly)

Heated Seats 

This system allows on-demand, independent, electrical heating of each front seat.

The heated seat system consists of the following components:

• Seat cushion heater mat
• Seat backrest heater mat
• The FDIM

Climate Controlled Seats 

This system allows on-demand, independent, electrical heating/cooling of each front seat.

The climate controlled seat system consists of the following components:

• Blower motor, located within each front seat cushion and backrest
• Air filter attached to each blower motor assembly (not serviceable)
• Climate controlled seat buttons, located on the FDIM (touchscreen)
• SCME, mounted to the bottom of the front passenger seat
• Cushion and backrest manifolds
• Cushion and backrest foam pads
• Cushion and backrest trim covers

Remote Start Climate Operation 

Different climate control modes/preferences can be selected 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 heated/climate controlled seat activates in full heat mode when the outside temperature is less than 0 ° C (32 ° F) and full cool mode (climate controlled seats only) when outside temperature is greater than 27 ° C (80 ° F) any time the vehicle is started using the remote start feature. No heated/climate controlled seat adjustments are recognized during remote start operation. Once the ignition is cycled ON, the heated/climate controlled seat returns to the previous settings (last ignition ON cycle) and adjustments can be made normally. If the previous setting was off, the heated/climate controlled seat turns off.

Multi-Contour Front Seats 

This system allows on-demand, independent, lumbar adjustment and/or massage of each front seat. PMI is required when a new SCMG or SCMH is installed.

The multi-contour front seat system consists of the following components:

• SCMG, attached to the backrest of the front driver seat
• SCMH, attached to the backrest of the front passenger seat
• Multi-contour seat buttons, located on the FDIM (touchscreen)
• Multi-contour seat control switch (part of the seat control switch)
• Front seat cushion adjuster, attached to each front seat frame (includes 6 inflatable air bladders and hoses)
• Front seat power lumbar assembly, attached to each front seat backrest (includes air pump, 5 inflatable air bladders and hoses)
