How do I install the Graco Extend2Fit in rear-facing mode?

Place the car seat in the back seat of your vehicle facing the rear, then secure it using either your vehicle's seat belt or LATCH system. Make sure the car seat is reclined at the appropriate angle for your child's age and size. Ensure the car seat is tightly secured and does not move more than an inch side-to-side or front-to-back.
