Important Safety Guidelines

Always read and understand the complete instruction manual before installing or using your car seat. Improper installation or use can lead to serious injury or death. Follow all weight and height limits for each mode of use. Never leave a child unattended in the car seat. Register your car seat to receive important safety updates and recall information.

Setup and Installation

Proper installation is crucial for your child's safety. This car seat can be installed using your vehicle's LATCH system or the vehicle's seat belt.

Rear-Facing Installation (5-40 lbs)

For infants and toddlers weighing 5-40 lbs. and up to 40 inches tall. Ensure the car seat is reclined to the appropriate angle for rear-facing use, typically indicated by a level indicator on the seat. The child's head must be at least 1 inch below the top of the car seat shell.

Forward-Facing Installation (22-65 lbs)

For children weighing 22-65 lbs. and 28-50 inches tall. The top of the child's ears must be below the top of the car seat's headrest. Use the vehicle's LATCH system or seat belt, along with the top tether strap.

Belt-Positioning Booster Installation (40-110 lbs)

For children weighing 40-110 lbs. and 44-57 inches tall. The car seat is used without the internal harness, positioning the vehicle's seat belt correctly over the child's shoulder and lap.

Operating Instructions

Harness Adjustment

The No Rethread Harness allows for easy adjustment of the shoulder straps to ensure a snug and proper fit as your child grows. Simply slide the harness straps up or down to the correct height without uninstalling the car seat.

Headrest Adjustment

The adjustable headrest can be moved up or down with one hand to provide optimal head and neck support for your child at every stage.

Buckle Pockets

Utilize the integrated Buckle Pockets to neatly tuck away the buckle tongues when not in use. This prevents hot buckle burns and makes it easier to place and remove your child from the seat.

Removable Head & Body Pillows

The positionable head and body pillows offer additional comfort and support, especially for smaller infants. These can be removed as your child grows and no longer requires the extra padding.

Maintenance and Care

Regular cleaning helps maintain the car seat's condition and hygiene.

Cleaning the Seat Pad

The seat pad is machine-washable. Refer to the care label on the fabric for specific washing instructions. Typically, it can be machine washed in cold water on a delicate cycle and tumble dried on low heat. Do not use bleach.

Cleaning the Harness and Buckle

Wipe the harness straps with a damp cloth and mild soap. Do not machine wash or submerge the harness straps, as this can weaken the webbing. Clean the buckle by rinsing it under warm water. Do not use detergents or lubricants on the buckle.

Cleaning Plastic and Metal Parts

Wipe plastic and metal parts with a damp cloth and mild soap. Do not use abrasive cleaners or solvents.

Troubleshooting

If you encounter issues with your car seat, refer to the following common solutions:

  • Difficulty Tightening LATCH: Ensure the LATCH connectors are fully engaged. Push down firmly on the car seat while pulling the LATCH strap to remove slack. The SureSafe system is designed to auto-tighten.
  • Harness Straps Not Adjusting Smoothly: Check for any twists in the harness webbing behind the car seat. Ensure the harness adjuster strap is pulled straight out from the front of the seat.
  • Buckle Sticking or Hard to Engage: Rinse the buckle under warm water to remove any debris. Do not use oils or lubricants. If the issue persists, contact customer support.
  • Car Seat Feels Loose After Installation: Re-read the installation instructions carefully. Ensure the car seat moves less than 1 inch side-to-side and front-to-back at the belt path. If using LATCH, ensure the top tether is also secured (for forward-facing).
