2. Safety Information

Important Warning: This product is suitable for children with a height between 126 cm and 150 cm. Installation must always be forward-facing. The child is secured using the vehicle's 3-point seat belt. While Isofix connections are available and recommended for stability, the child car seat can also be secured solely with the 3-point belt. Always read the instruction manual carefully before use.

Ensure the booster seat is always correctly installed and the child is properly secured with the vehicle's 3-point belt. Never leave a child unattended in the booster seat.

3. Setup and Installation

The Osann Junior Isofix i-Size Booster Seat offers flexible installation options to suit various vehicles.

3.1. Installation with Isofix and 3-Point Belt

For optimal stability and ease of installation, use the integrated Isofix connectors in conjunction with the vehicle's 3-point seat belt.

  1. Locate the Isofix anchor points in your vehicle's back seat.
  2. Extend the Isofix connectors on the booster seat by pressing the release buttons (refer to Figure 3).
  3. Align the Isofix connectors with the vehicle's anchor points and push the booster seat firmly until you hear an audible 'click' on both sides, indicating a secure connection.
  4. Push the booster seat firmly against the vehicle seat back to ensure a snug fit.
  5. Once the child is seated, route the vehicle's 3-point seat belt through the designated belt guide on the booster seat and buckle it securely. Ensure the lap belt is low across the hips and the shoulder belt crosses the chest and shoulder, not the neck.

3.2. Installation with 3-Point Belt Only

If your vehicle does not have Isofix anchor points, or if you prefer, the booster seat can be secured solely with the vehicle's 3-point seat belt.

  1. Place the booster seat firmly on the vehicle seat.
  2. Once the child is seated, route the vehicle's 3-point seat belt through the designated belt guide on the booster seat and buckle it securely. Ensure the lap belt is low across the hips and the shoulder belt crosses the chest and shoulder, not the neck.
  3. Always double-check that the belt is not twisted and fits snugly against the child's body and the booster seat.

4. Operating the Booster Seat

Using the Osann Junior Isofix i-Size Booster Seat is straightforward, focusing on securing your child comfortably and safely with the vehicle's 3-point seat belt.

  1. Ensure the booster seat is correctly installed in the vehicle (refer to Section 3).

  3. Pull the vehicle's 3-point seat belt across your child and through the red belt guide located on the booster seat (refer to Figure 4).
  4. Buckle the seat belt securely.
  5. Adjust the lap belt so it sits low across your child's hips, not across the stomach.

5. Maintenance

Proper maintenance ensures the longevity and hygiene of your Osann Junior Isofix i-Size Booster Seat.

5.1. Cleaning the Cover

The comfort cover of the booster seat is designed for easy removal and cleaning.

  1. Carefully remove the fabric cover from the booster seat frame.
  2. Machine wash the cover at 30°C on a delicate cycle.
  3. Do not bleach, tumble dry, iron, or dry clean the cover.
  4. Allow the cover to air dry completely before reattaching it to the booster seat.

6. Troubleshooting

If you encounter any issues with your Osann Junior Isofix i-Size Booster Seat, please refer to the following common solutions:

  • Booster seat feels loose after installation: Ensure the Isofix connectors are fully engaged (if applicable) and pushed firmly against the vehicle seat. If using only the 3-point belt, pull all slack out of the belt to ensure a snug fit.
  • Seat belt does not fit correctly: Double-check that the vehicle's 3-point belt is routed through the red belt guide on the booster seat and is not twisted. Adjust the belt to ensure it crosses the child's shoulder and chest, not the neck, and the lap belt is low across the hips.
  • Difficulty removing the cover: Refer to the detailed instructions in Section 5.1. If still having trouble, gently check for any hidden clips or fasteners.

If the problem persists or if you have any other concerns, please contact Osann customer support.
