Product Overview
The Cosco Kids Finale DX 2-in-1 Booster Car Seat is a versatile child restraint system. It features a lightweight design for easy transfer between vehicles and a narrow profile that allows for three-across seating in most vehicles. Key features include a 5-point safety harness for younger children and a belt-positioning mode for older children, along with removable, dishwasher-safe cup holders.

Setup and Installation
Modes of Use:

- Belt-Positioning Booster: For children weighing 40-100 lbs and measuring 43.4"-52" in height.
General Installation Steps:
- Place the car seat on the vehicle seat, ensuring at least 80% of the car seat base is on the vehicle seat.
- Route the vehicle's seat belt through the designated belt path for the chosen mode of use.
- Buckle the vehicle seat belt and remove all slack to ensure a tight fit. The car seat should not move more than 1 inch side-to-side or front-to-back at the belt path.

Operating Instructions
Securing Your Child in Harness Mode:
- Place your child in the car seat with their back flat against the seat back.
- Bring the harness straps over your child's shoulders. Ensure the harness straps are at or above your child's shoulders for forward-facing use.
- Buckle the crotch buckle between your child's legs.
- Connect the chest clip at armpit level.
- Tighten the harness straps until snug. Perform the "Pinch Test": if you can pinch any excess webbing at your child's shoulder, the harness is too loose and needs further tightening.

Using in Belt-Positioning Booster Mode:
- Remove the 5-point harness system as instructed in the full product manual.
- Place your child in the booster seat.
- Route the vehicle's lap and shoulder belt over your child and through the designated belt guides on the booster seat.
- Ensure the lap belt lies low across the hips, touching the thighs, and the shoulder belt rests snugly across the center of the child's shoulder and chest.
- Buckle the vehicle seat belt and remove all slack.

Maintenance
- Seat Pad: The removable seat pad is machine-washable and dryer-safe. Refer to the care label for specific washing instructions.
- Cup Holders: The removable cup holders are dishwasher-safe for easy cleaning.
- Harness Straps: Wipe harness straps with a damp cloth. Do not machine wash or immerse in water, as this may weaken the webbing.
- Plastic/Metal Parts: Wipe plastic and metal parts with a damp cloth and mild soap.

Troubleshooting
- Car Seat is Loose After Installation: Ensure all slack is removed from the vehicle seat belt. Press down firmly on the car seat while tightening the belt. Re-check for movement (should not move more than 1 inch).
- Harness Straps are Difficult to Adjust: Check for any twists in the harness webbing. Ensure the harness adjuster strap is pulled straight out from the car seat.
- Child's Head is Slumping: Ensure the headrest is adjusted to the correct height for your child. For forward-facing, the harness straps should be at or above the shoulders.
- Cup Holder Not Fitting: Ensure the cup holder is correctly aligned with its slot and pushed firmly into place.
