Seat Identification

1991 Cadillac Seville STSSECTION Seat Identification

Seats are identified by option code. The 3 options available are the AQ9 Bucket Seat, AR9 Bucket Seat or the AM6 Split Bench Seat. Refer to the vehicle body number plate or the service parts identification label to verify the specific seat option code. The AQ9 bucket seat provides power recliners, wing and thigh support, and also has a manual head rest. In addition, the AQ9 offers a six way power seat adjuster for the driver and a manual adjuster for the passenger. A 6-way power seat adjuster is optional for the passenger seat. The AR9 bucket seat and the AM6 split bench seat both offer two way, manual driver and passenger seat recliners. In addition, both seats offer a 6-way power seat adjuster for the driver and a manual adjuster for the passenger.

A 6-way power seat adjuster is optionally available for the passenger seat. The three-motor, direct drive, low profile seat adjuster assembly, is used on all seats. All folding seats are equipped with inertia seatback locks which are an integral part of the recliner assembly. This feature allows the seatback to move freely without requiring the occupant to release a lock lever for access to the rear seat area. On sudden stops, deceleration, or if the front of the vehicle is declined 20 degrees or more, with the seatback in an upright position, the seat back will lock in it current position. A seatback lock release lever is provided to allow manual release of the inertia lock when the front of the vehicle is, declined 20 degrees or more. The release lever is located on the lower, outboard corner of the seatback.
