How do I recline the car seat base?

The base has three recline positions. Position 1 is the least reclined position with no wedge attached. For position 2, attach the base wedge with the label marked '2' facing up. For position 3, attach the base wedge with the label marked '3' facing up. If needed, rolled towels may be placed under the base at the vehicle seat crease until the level line is level with the ground. (Pages 20-21)
