FIRST SETUP
HARNESS SETUP
1. Place your child in the seat. Make sure their back is flat
against the car seat back (this can be done in or out of
the car). Avoid bulky or heavy clothing because they
will prevent the harness straps from being tightened
properly at first fitment.
2. Place harness straps over child's shoulders and legs and
buckle. You will hear a "click" when buckle tongues are
securely attached. Pull up on each buckle tongue to
make sure it is securely attached.
3. Be sure the harness straps are at the proper height.
