Bucket Seats

If your vehicle has bucket seats, you can adjust the seats several different ways.

Fore-and-Aft Adjustment

Caution: You can lose control of the vehicle if you try to adjust the seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver's seat only when the vehicle is not moving.


Object Number: 829580  Size: A2

The fore-and-aft adjustment lever is located underneath the front of the seat.

To slide the seat forward or rearward, move the lever toward the driver's side of the vehicle. The seat will lock in at 1/2 inch (1.5 cm) increments.

Lumbar Adjustment


Object Number: 810961  Size: A3

The lumbar adjustment knob is located on the seatback, on the inboard side of the driver's seat and on the outboard side of the passenger's seat.

For more support to your lower back, turn the lumbar adjustment knob clockwise. To decrease the amount of lumbar support, turn the knob counterclockwise.

Seatback Adjustment


Object Number: 829577  Size: A3

The seatback adjustment knob is located on the inboard side of the driver's and passenger's seat cushions.

Caution: If either seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatbacks to be sure they are locked.

To tilt the seatback rearward, turn the knob counterclockwise. Turn the knob clockwise to tilt the seat forward.
