2. Setup and Installation

Proper installation of the Diono Connect3 R booster seat is crucial for child safety. Always refer to your vehicle's owner's manual for specific car seat installation instructions and locations.

High-Back Booster Installation:

  1. Place the booster seat firmly on the vehicle seat. Ensure the booster head support or backrest contacts the vehicle seat head support or seat back.
  2. To secure the child, thread the vehicle's shoulder belt through the upper belt guide located on the booster's headrest.
  3. Route the vehicle's lap belt under the belt guide on the booster seat.
  4. Then, route both the lap and shoulder belt under the belt guide closest to the buckle and buckle the seat belt. Ensure the belt is snug across the child's hips and shoulder.

3. Operating Instructions

Using the High-Back Booster:

Ensure your child is properly seated with their back against the booster seat. The vehicle's lap belt should lie low across the hips, touching the thighs, and the shoulder belt should rest across the center of the child's shoulder and chest, not on the neck or off the shoulder. Adjust the headrest to ensure the shoulder belt guide is positioned correctly above your child's shoulders.

Converting to Backless Booster:

The Connect3 R can be converted to a backless booster for older children. To convert, detach the backrest from the booster base. The backless booster mode includes a shoulder belt positioning clip to ensure the vehicle's shoulder belt is correctly positioned across your child's shoulder. A carry handle is integrated for portability.

Adjusting the Headrest:

The headrest can be adjusted to 11 different positions to accommodate your growing child. To adjust, locate the adjustment lever or button, typically at the top or back of the headrest, and raise or lower it to the desired height. Ensure the shoulder belt guide is slightly above your child's shoulders.

Using the Cupholder:

The removable cupholder can be attached to either side of the booster seat. For a 3-across fit, the cupholder is designed to nest between Connect3 seats. When not in use or for travel, it can be stored conveniently under the booster seat.

4. Maintenance and Care

Regular maintenance ensures the longevity and cleanliness of your booster seat. The seat cover is made of polyester and can be removed for cleaning. Refer to the care label on the seat cover for specific washing instructions. Typically, machine wash cold on a delicate cycle and air dry. Do not use bleach or harsh detergents.

Periodically inspect the booster seat for any signs of wear or damage, including cracks in the plastic, frayed straps, or loose components. If any damage is found, discontinue use and contact Diono customer support.

5. Troubleshooting

If you encounter any issues with your Diono Connect3 R booster seat, please review the following common concerns:

  • Loose Installation: Ensure the booster seat is placed firmly on the vehicle seat and the vehicle's seat belt is routed correctly and pulled taut. The booster should not move more than one inch side-to-side or front-to-back at the belt path.
  • Seat Belt Twisting: Always ensure the vehicle's seat belt is flat and untwisted when routing it through the booster's belt guides and buckling.
  • Headrest Adjustment Difficulty: Check for any obstructions and ensure the adjustment mechanism is free of debris. Apply gentle, even pressure when adjusting.
  • Cupholder Issues: Ensure the cupholder is correctly inserted into its designated slot. If it feels loose, re-insert it firmly.

For issues not covered here, or if problems persist, please contact Diono customer support.
