Front Seat

The front seats are bucket seats.

The driver and the front passenger seats have the following features:

    • Inertia seatback locks
    • Manual seatback recliners
    • Manual seatback adjuster

For the driver's seat only, the following features can be ordered:

    • A 4-way manual seat adjuster
    • A 6-way power seat adjuster

Also, both driver and front passenger seats can be ordered as pneumatic seats. Pneumatic seats have an adjustable thigh support. For Pontiac only, inflatable lumbar and lateral support bladders can be ordered.

The seatback and the cushion have formed foam pads that fit the contours of the seatback and the seat cushion frames.

Front Seatback

Bucket seats have a tubular frame seatback and a standard manual seatback recliner. The recliner control is mounted on the outboard side of the seat. The recliner control operates the seatback angle. The inner hinge arm bolt acts as a pivot point for the seatback. The recliner control has an inertia seatback lock that lets the occupant move the seatback without the lever.

The inertia seatback lock locks the seatback. Use the emergency release lever in order to move the seatback if the following conditions occur:

    • If the vehicle stops or slows suddenly
    • If the vehicle is declined 20 degrees or more

Lift the reclining control handle in order to change the seatback angle. Lifting the recliner control handle releases the lock bars and lets the seatback pivot forward and rearward. Releasing the recliner control handle lets the cam plate move counterclockwise. This causes the lock bar teeth to lock the seatback in a new position. The recliner control handle should return automatically to its original position.
