Setup and Installation
Proper installation is crucial for your child's safety. Always refer to the full user manual (PDF link provided at the end of this document) for detailed instructions specific to your vehicle and child's weight/height.
Stage 1: Forward-Facing Harness (22-65 lbs)
For children weighing 22-65 lbs, the car seat should be used in the forward-facing harnessed mode. Ensure the 5-point harness is properly adjusted and snug against your child.

Stage 2: High-Back Belt-Positioning Booster (40-100 lbs)
Once your child outgrows the harnessed mode (or reaches 65 lbs), convert the seat to a high-back belt-positioning booster. The vehicle's lap and shoulder belt will be used to secure your child.

Stage 3: Backless Belt-Positioning Booster (40-100 lbs)
For older children, the back of the car seat can be removed to use it as a backless belt-positioning booster. Ensure the vehicle's lap and shoulder belt are correctly positioned across your child's body.

Maintenance and Care
Regular cleaning and maintenance will help prolong the life of your car seat and ensure continued safety.
Cleaning Instructions:
- Seat Cushion: The seat cushion is machine-washable. Refer to the care tag for specific washing instructions.
- Metal and Plastic Parts: Clean with mild soap and cool water.
- Buckle: May be cleaned with a damp cloth. For thorough cleaning, remove the buckle from the car seat by pushing the retainer through the harness strap slot. Place the buckle in a cup of warm water upside down and gently agitate, pressing the red button several times. Do not submerge harness webbing and do not use soaps or lubricants. Rinse with warm water, shake out excess, and air dry. Reattach the buckle into the same slot and re-check installation before use.
- Harness Straps: May be spot cleaned only. Do not machine wash or immerse harness straps in water, as this may weaken them.
