The Evenflo Symphony DLX supports three modes of use. Always refer to your vehicle's owner's manual for specific car seat installation instructions and LATCH system weight limits.
4.1. Rear-Facing Mode (Infant)
For infants weighing 5-40 lbs and measuring 19-40 inches in height. The car seat must be installed rear-facing in the back seat of the vehicle.
- Ensure the car seat is reclined to the appropriate angle for a rear-facing infant.
- Use either the vehicle's seat belt or the Sure LATCH connectors for installation.
- When using Sure LATCH, simply click the connectors onto your vehicle's lower anchors and push the car seat firmly into place. The self-tightening mechanism will secure the seat in approximately 60 seconds.
- Verify the car seat is securely installed and does not move more than one inch side-to-side or front-to-back at the belt path.
4.2. Forward-Facing Mode (Toddler)
For toddlers weighing 22-40 lbs and measuring 28-50 inches in height. The car seat must be installed forward-facing in the back seat of the vehicle.
- Adjust the car seat to the upright forward-facing recline position.

- Position the car seat in the vehicle's back seat.
- Route the vehicle's lap and shoulder belt correctly through the designated guides on the booster seat and across the child.

7. 문제 해결
If you encounter any issues with your Evenflo Symphony DLX car seat, please consult the following common solutions:
- 조절하기 어려운 하네스: Ensure the harness straps are not twisted. Check for any obstructions in the harness adjustment mechanism.
- 차량용 시트를 설치한 후 헐렁한 느낌이 듭니다. Re-read the installation instructions carefully. Ensure Sure LATCH connectors are fully engaged and the seat belt is tightened correctly. Apply firm pressure to the car seat while tightening.
- Child's head slumps forward: In rear-facing mode, ensure the car seat is reclined to the correct angle. A rolled towel or pool noodle can be used at the vehicle seat crease to achieve the proper recline angle, as permitted by the full instruction manual and your vehicle's manual.
