Forward and Backward Adjustment

To move the seat forward or backward:

1. Pull up the seat slide adjustment lever and hold it.

2. Slide the seat to the desired position.

3. Release the lever and make sure the seat is locked in place. Try to move the seat forward and backward without using the lever. If the seat moves, it is not locked properly.

Seatback Angle

To recline a seatback:

1. Lean slightly forward and lift the seatback recline lever.

2. Carefully lean back and adjust the seatback to the desired position.

3. Release the lever and make sure the seatback is locked. (The lever MUST return to its original position for the seatback to lock.)

Reclining Seatback

Sitting in a reclined position while the vehicle is moving can be dangerous. Even when buckled up, the protection of your restraint system (seat belts and airbags) is significantly reduced if the seatback is reclined.

WARNING

NEVER sit behind the steering wheel with the seatback reclined while the vehicle is moving.

Riding with the seatback reclined increases the likelihood of serious or fatal injury in a collision or sudden stop.

Drivers and passengers must ALWAYS sit upright in their seats, properly wearing their seat belts, with the seatbacks in the upright position.

For proper operation, seat belts must fit snugly across the hips and chest. When the seatback is reclined, the shoulder belt cannot perform its function because it will not fit snugly against the chest. Instead, it will be in front of you. In an accident, you may slide under the seat belt, which may result in neck injury or other injuries.

The more the seatback is reclined, the greater the likelihood that the occupant's hips will slide under the lap belt, or that the occupant's neck will strike the shoulder belt.

Seat Cushion Height

To change the seat cushion height:

  • Pump the lever several times to lower the seat cushion.
  • Pump the lever up several times to raise the seat cushion.
