Front Seats Bucket Seats On vehicles with bucket seats, you can adjust the seats several different ways. Fore-and-Aft Adjustment { WARNING: 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. 1-2

You can adjust the seat forward or rearward with the bar located under the front of the seat cushion. Lift the bar to unlock the seat. Slide the seat to where you want it and release the bar. Try to move the seat with your body to be sure the seat is locked in place. Lumbar Adjustment Your seats may have this feature. 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. 1-3

Seatback Adjustment { WARNING: You can lose control of the vehicle if you try to adjust a manual driver's 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. { WARNING: 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. The recline lever is located on the outboard side of the driver's and passenger's seat cushions. To recline the seatback, do the following: 1. Lift the recline lever. 2. Move the seatback to the desired position, then release the lever to lock the seatback in place. 3. Push and pull on the seatback to make sure it is locked. To return the seatback to an upright position, do the following: 1. Lift the lever fully without applying pressure to the seatback and the seatback will return to the upright position. 2. Push and pull on the seatback to make sure it is locked. 1-4

{ WARNING: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt cannot do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly. Do not have a seatback reclined if your vehicle is moving. 1-5

Split Bench Seat (80/20 Split) If your vehicle has a split bench seat, the passenger seat is not adjustable. There is a storage area underneath the seat cushion. See Storage Areas on page 2‑50. Air Suspension Seats Your vehicle may have a low-back or high-back air suspension seat. There are several ways to adjust the seat. Fore-and-Aft Adjustment If your vehicle has this lever it is located underneath the front of the driver's seat. To slide the seat forward or rearward, move the lever toward the outboard side of the seat. The seat will lock in at 1/2 inch (1.5 cm) increments. Try to move the seat with your body to be sure the seat is locked in place. Height Adjustment Seat Height Adjustment Lever On a vehicle with an air suspension seat height adjustment lever, it is located on the front inboard side of the seat. To adjust the height of the air suspension seat, pull the lever up to inflate. Push the lever down to deflate. Your seat cushion may also be able to be raised or lowered. 1-6
