Setup and Installation
Vehicle Compatibility
The Osann Swift360 S i-Size is designed for vehicles equipped with ISOFIX anchor points and a Top-Tether attachment point. Refer to your vehicle's owner's manual to confirm compatibility and proper installation locations.
Installation Steps
- Prepare the Seat: Ensure the seat is in the correct orientation (rear-facing for 76-105 cm, forward-facing for 76-150 cm).
- Extend ISOFIX Connectors: Press the release buttons to extend the ISOFIX connectors from the base of the car seat.
- Attach ISOFIX: Align the ISOFIX connectors with the ISOFIX anchor points in your vehicle and push firmly until they click into place. Green indicators will confirm correct attachment.
- Secure Top-Tether: Route the Top-Tether strap over the back of the vehicle seat and attach the hook to the designated Top-Tether anchor point in your car. Tighten the strap until the indicator turns green (if applicable) and the seat is firmly secured.
- Verify Installation: Gently pull on the car seat to ensure it is securely fastened and does not move excessively.

Operating Instructions
360-Degree Rotation
The Swift360 S i-Size features a convenient 360-degree rotation function. To rotate the seat, ensure the child is not in the seat and disengage any locking mechanism (refer to specific lever/button on the base). Rotate the seat to face the car door for easy child placement or removal, then rotate it back to the desired driving position (rear-facing or forward-facing) until it locks securely.

Headrest and Harness Adjustment
The headrest is 12-way height adjustable, allowing the seat to grow with your child up to 150 cm. The harness system automatically adjusts with the headrest. To adjust, locate the headrest adjustment lever (usually at the top or back of the headrest) and pull it up or push it down to the desired height. Ensure the shoulder straps are at or just below the child's shoulders when rear-facing, and at or just above when forward-facing.

Recline Positions
The seat offers 5 recline positions for optimal comfort and safety. To adjust the recline, locate the recline adjustment handle (typically at the front or side of the base) and pull it while simultaneously tilting the seat to the desired position. Ensure the seat clicks into place in the chosen recline setting.

Magnetic Belt Holders
For easier placement of your child, the seat includes magnetic holders for the shoulder belts. When placing the child in the seat, attach the shoulder belts to the magnetic points on the sides of the seat to keep them out of the way. Once the child is seated, release the belts from the magnets and buckle them securely.

Maintenance and Care
Cleaning the Cover
The seat cover is made of 100% polyester and can be removed for cleaning. It is machine washable at 30 degrees Celsius on a gentle cycle. Do not tumble dry, bleach, or iron the cover. Allow it to air dry completely before reattaching it to the seat frame.
Cleaning the Frame
The plastic and metal parts of the seat frame can be wiped clean with a damp cloth and mild soap. Avoid using abrasive cleaners or solvents. Ensure all parts are dry before reassembly or use.
Troubleshooting
- Seat not rotating smoothly: Check for any obstructions around the base or if the rotation lock is engaged. Ensure the seat is not under tension from the vehicle's seatbelt if not using ISOFIX.
- Harness difficult to tighten/loosen: Ensure the harness straps are not twisted. Check for any debris in the buckle mechanism.
- ISOFIX indicators not turning green: Re-engage the ISOFIX connectors firmly until you hear a click and the green indicators are visible. Ensure no fabric or other items are obstructing the connection.
- Top-Tether not tightening: Verify the Top-Tether strap is correctly routed and the hook is securely attached to the vehicle's anchor point. Pull the strap firmly to remove slack.
