Safety First: Important Warnings and Precautions

Prioritize safety! Always read the owners manual completely before installing or using the Evenflo Symphony. Incorrect installation can significantly reduce the car seat’s protective capabilities. Never use the car seat if it has been involved in a moderate to severe accident.
Regularly check the harness straps for wear and tear, and ensure they are properly adjusted to your child’s size. Do not add any aftermarket products or padding that did not come with the seat.
Proper disposal of the car seat is also crucial; Evenflo requests appropriate disposal of the product when it is no longer usable. Refer to the PDF manual for detailed safety guidelines.
Component Identification
Familiarize yourself with the Evenflo Symphony’s parts. Key components include the base, harness straps, buckle, recline mechanism, and headrest. The owners manual details each part’s function and adjustment features.
Understanding the harness system parts – chest clips, shoulder straps, and crotch buckle – is vital for secure restraint. The base provides a stable foundation, while the headrest offers adjustable support as your child grows.
Refer to the PDF manual for detailed diagrams illustrating each component. Correct identification ensures proper installation and usage, maximizing the car seat’s safety benefits.
Identifying the Base Components
The Evenflo Symphony base features several key elements for secure installation. Locate the LATCH connectors and tether strap attachment points – crucial for both rear and forward-facing modes. Examine the recline indicators, ensuring proper angle adjustment for infant safety.
Identify the belt-locking mechanism, used for installation with vehicle seatbelts. The base also includes leveling indicators to confirm a stable and secure fit. Refer to the owners manual for specific base component diagrams.
Understanding these base components is essential for correct installation, as detailed in the PDF manual, guaranteeing optimal protection for your child during travel.
Recognizing the Harness System Parts
The Evenflo Symphony’s harness system comprises several vital components. Identify the five-point harness straps – shoulder belts and the crotch buckle – ensuring they are free from twists. Locate the harness adjuster, used to tighten or loosen the straps for a snug fit.
Familiarize yourself with the buckle release button, for easy child removal. Note the chest clip’s position, maintaining proper strap placement. The owners manual details re-threading instructions for adjusting harness height as your child grows.
Correctly recognizing and utilizing these parts, as illustrated in the PDF manual, is paramount for optimal safety and restraint during every journey.
Installation Guide: Rear-Facing Mode
Rear-facing installation is the safest position for infants and young toddlers. Begin by securely installing the base, utilizing the vehicle’s lower anchors or the seatbelt, following the owners manual’s detailed instructions. Ensure the base is level; adjust the recline indicator accordingly.
Thread the harness straps through the correct slots, confirming they are not twisted. Always use the harness adjuster to achieve a snug, yet comfortable fit. Refer to the PDF manual for specific weight and height limits for rear-facing mode.

Double-check all connections before each ride, prioritizing a stable and secure installation.
Proper Base Installation Techniques
Secure base installation is paramount for child safety. Utilize either the vehicle’s LATCH system or the seatbelt, ensuring a tight fit – movement should not exceed one inch side-to-side or front-to-back. Consult the owners manual for vehicle-specific compatibility.
Employ the recline indicator to achieve the correct angle for your child’s age and weight, as detailed in the PDF manual. Verify the base is level using a bubble level if available. Always double-check the belt path when using the seatbelt installation method;
A properly installed base forms the foundation for a safe ride.
Harness Adjustment for Infants

Infant harness adjustment requires meticulous attention. Always use the lowest harness slots, positioned at or below the infant’s shoulders for rear-facing mode, as outlined in the owners manual. Ensure the harness straps are snug – you should not be able to pinch any excess webbing at the shoulder.
The chest clip should be positioned at armpit level to properly distribute impact forces. Regularly check the harness tightness as the infant grows; refer to the PDF manual for re-threading instructions when necessary.
A secure, properly fitted harness is vital for infant protection.
Installation Guide: Forward-Facing Mode
Transitioning to forward-facing requires careful attention to the Evenflo Symphony’s installation. Ensure the base is securely installed, following all instructions in the owners manual. Always utilize the top tether strap; it significantly reduces head excursion during a crash, enhancing safety.
Verify the car seat doesn’t move more than one inch side-to-side or front-to-back when tested at the belt path. Refer to the PDF manual for specific tether anchor point locations in your vehicle. Regularly check installation tightness as the child grows.
Proper installation is paramount for forward-facing safety.
Using the Tether Strap for Enhanced Safety
The tether strap is a critical safety component when using the Evenflo Symphony in forward-facing mode. It minimizes forward movement during a sudden stop or collision, reducing the risk of head injury. Always connect the tether to the designated anchor point in your vehicle – consult your vehicle’s owners manual for its location.
Ensure the tether is snug, but not overly tightened, allowing for slight movement. A properly secured tether significantly improves the car seat’s performance in a crash. Refer to the PDF manual for detailed illustrations and instructions on tether strap usage and adjustment.
Adjusting Harness and Recline Positions
Proper adjustment of the harness and recline is vital for your child’s comfort and safety within the Evenflo Symphony. Regularly check the harness straps to ensure a snug fit – you should not be able to pinch any excess webbing at the shoulder. Adjust the harness height as your child grows, utilizing the designated slots.
Recline positions should be appropriate for your child’s age and size; refer to the owners manual or PDF manual for guidance. Avoid overly reclined positions in forward-facing mode. Always double-check these adjustments before each journey to guarantee optimal protection.
Booster Mode Setup

Transitioning to booster mode with the Evenflo Symphony offers continued safety as your child grows. The Symphony functions as both a high-back and backless booster. For the high-back configuration, ensure the headrest is adjusted to the correct height, positioning the vehicle seat belt across your child’s shoulder and chest – never the face or neck.
When utilizing backless booster mode, confirm the vehicle’s seat has a headrest or high seatback for adequate protection. Always consult the owners manual or PDF manual for specific height and weight requirements before switching to booster mode.
High-Back Booster Configuration
Setting up the high-back booster involves several key steps for optimal safety. First, ensure the headrest is adjusted to the appropriate height, positioning the vehicle’s three-point seat belt correctly across your child’s shoulder and chest – crucially, not across the face or neck.
Refer to the Evenflo Symphony owners manual or the downloadable PDF manual for detailed illustrations and weight/height limits. Proper belt fit is paramount. The high-back provides added side impact protection. Regularly check the adjustment as your child grows, maintaining correct positioning for every ride.
Backless Booster Mode Instructions
Transitioning to backless booster mode requires removing the high back, ensuring proper vehicle seat compatibility. Always consult the Evenflo Symphony manual or PDF guide before making this change. Verify your vehicle’s seat is designed to accommodate a backless booster safely.
The vehicle’s three-point seat belt must fit correctly across your child’s upper thighs and shoulder. Never allow the belt to cross the neck or face. Regularly check the belt positioning as your child grows. This mode is suitable only for older, larger children meeting the specified height and weight requirements detailed in the owners manual.
Harness Adjustment and Re-Threading
Adjusting the harness is vital as your child grows. The Evenflo Symphony features a no-rethread harness, simplifying adjustments. Locate the adjustment strap near the headrest and pull to tighten or release. Ensure the harness straps are snug, allowing no more than one finger’s width of space between the strap and your child’s collarbone.
If re-threading is ever necessary (consult your owners manual for specific scenarios), carefully follow the illustrated instructions in the PDF manual. Incorrect re-threading compromises safety. Always double-check the harness lock-off mechanism after any adjustment or re-threading to confirm secure installation.
Cleaning and Maintenance

Maintaining your Evenflo Symphony ensures longevity and hygiene. For fabric care, remove the cover and hand wash with mild soap and water. Air dry thoroughly – do not machine dry. Regularly check for any tears or damage to the fabric.
Plastic components can be cleaned with a damp cloth and mild detergent. Avoid abrasive cleaners, as they may damage the surface. Inspect the buckle and harness regularly for wear and tear. Refer to the owners manual or PDF manual for detailed cleaning instructions and proper care to keep your car seat safe and clean.
Fabric Care Instructions
To clean the Evenflo Symphony’s fabric cover, carefully remove it from the car seat frame. Hand wash the fabric using lukewarm water and a mild, gentle detergent. Avoid using bleach or harsh chemicals, as these can damage the material and compromise safety.
After washing, rinse thoroughly to remove all soap residue. Gently squeeze out excess water – do not wring. Lay the fabric flat to air dry completely. Do not place in a dryer, as heat can shrink or distort the fabric. Regularly inspect for wear and tear, referencing the PDF manual.
Plastic Component Cleaning
To maintain the Evenflo Symphony’s plastic components, wipe them down regularly with a damp cloth and mild soap solution. Avoid abrasive cleaners, as they can scratch or damage the plastic surfaces. Pay particular attention to areas that frequently come into contact with hands, like the buckle and adjustment buttons.
Ensure all soap residue is removed with a clean, damp cloth. Allow the plastic to air dry completely before reassembling or using the car seat. Inspect for cracks or damage regularly, consulting the owners manual for guidance. Proper cleaning ensures longevity and safety.
Troubleshooting Common Issues
Experiencing difficulties? If the harness straps become twisted, re-thread them following the manual’s instructions. For base installation problems, double-check the LATCH connectors or belt path, ensuring a secure fit. If the recline adjustment isn’t working, verify it’s not obstructed.
Difficulty locating the correct tether attachment point? Consult your vehicle’s owners manual. If you’re unsure about any issue, don’t hesitate to contact Evenflo Customer Service for assistance. Always prioritize safety and refer to the PDF manual for detailed guidance.
Understanding the Symphony’s Height and Weight Limits
Crucially, the Evenflo Symphony All-in-One car seat has specific height and weight limits for each mode – rear-facing, forward-facing, and booster. Always consult the owners manual or PDF manual for the most up-to-date specifications. Exceeding these limits compromises safety.

Recent updates may have increased height limits; verify this information. Ensure your child hasn’t outgrown the seat before each stage transition. Regularly check height and weight to maintain optimal protection. Prioritize adherence to these guidelines for your child’s wellbeing.
