Manual Adjustment
Forward and Backward Adjustment

To move the seat forward or backward:
1. Lift 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. Turn the seatback recline knob rearward.
2. Adjust the seatback to the desired position.
Reclining Seatback
Sitting in a reclined position while the vehicle is moving can be dangerous. Even when buckled, the protection of your restraint system (seat belts and/or airbags) is significantly reduced by reclining the seatback.
WARNING
NEVER drive with the seatback reclined while the vehicle is moving.
Riding with the seatback reclined increases your chance of serious or fatal injury in a collision or sudden stop.
Drivers and passengers should ALWAYS sit comfortably in their seats, properly belted, with the seatbacks in the upright position.
The seat belts must fit snugly against the hips and chest to function properly. When the seatback is reclined, the shoulder belt cannot perform its function because it will not fit snugly against your chest. Instead, it will be positioned in front of you. In a collision, you may slide under the seat belt, resulting in neck or other injuries.
The more the seatback is reclined, the greater the chance that the passenger's hips will slide under the lap belt or the passenger'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.
- Pull the lever up several times to raise the seat cushion.
