Lost Manual need help converting to Booster

This car seat does not convert to a booster. It becomes a "Belt-positioning booster". The back and headrest remain while using as a booster. You remove the 5-point harness and use the car's shoulder strap seat belt.
The belt positioning is done by the plastic parts at the top on either side of the seat.

Hi,
please feel free to call at 1-800-544-1108 and they can send you a manual in case you dont have it.

*To convert the car seat into a booster seat, turn the car seat over and remove the pin that holds the base in place. tHEN REMOVE THE BELTS AND THE BUCKLE.
*To remove you need to bend/twist the keeper until you can push it UP through the seat and remove the belt/strap. It is now a booster seat for use with a lap/shoulder belt in the car. Store all the parts you removed in a ziploc bag for when your child outgrows it so it can be reused

PLEASE RATE MY HELP :)

Turn the booster seat around to the back and locate the metal splitter plate that the harness is attached to. Remove both harness straps from the splitter plate. Locate the TensionRight knob located on each side of the seat in the front by the baby’s foot area. Turn the TensionRight knob to the back as far as it will go to take up the slack on the splitter plate strap. Pull both harness straps through the seat back to the front of the seat. Remove the harness strap from both sides of the chest clip and from the buckle tongues. NOTE: Please leave the buckle tongues locked into the **** strap for storage. Remove the harness strap from the seat. NOTE: Reattach the chest clip to the harness strap so they don’t get lost. Turn the booster seat upside down and locate the metal harness anchor. Turn the metal anchor sideways and push it through the slot to the front of the seat.

To change it into a belt positioning booster seat, you remove the harness straps completely and use the positioning clips on the side of the carseat (up by the head) to position the automobile's seat belt to the appropriate position.

The base is what makes it a booster seat. Some seats the back is removed but if yours is the one in the picture, it looks like you have a belt positioning booster seat (much better than a regular booster). You would remove the harness straps completely and place the automobile's seatbelt through the appropriate slots on the side of the carseat up by the shoulder/head and feed it across your child rather than through the seat. For best use, look in your owner's manual for instructions. If you no longer have it, generally you can download one on-line from the manufacturer at no charge.
