Locate the harness adjustment slots on the back of the car seat. To raise the harness‚ depress the red release button and simultaneously pull the shoulder straps upwards through the desired slots.
To lower the harness‚ depress the release button and push the shoulder straps downwards. Ensure both sides are adjusted to the same height‚ maintaining a level position. The straps should be at or slightly above your child’s shoulders when in rear-facing mode‚ and at or below their shoulders when forward-facing. Regularly check and adjust the harness height as needed for a secure fit.
Buckle and Strap Adjustments for Proper Fit
Achieving a snug and secure fit with the harness is paramount for child safety. Begin by ensuring the buckle clicks firmly together. The chest clip should be positioned at armpit level‚ helping to keep the harness straps properly positioned on your child’s shoulders. To tighten the harness straps‚ pull the adjustment strap located near the buckle.
The straps should be snug enough that you cannot pinch any excess webbing at the shoulder. However‚ avoid overtightening‚ allowing a comfortable fit. To loosen the straps‚ press the red release button on the buckle. Regularly check the fit‚ especially after adjusting clothing. A properly adjusted harness minimizes movement in a crash‚ maximizing protection.

Usage by Child Weight & Height
The Evenflo Symphony adapts to your growing child‚ offering distinct modes – rear-facing‚ forward-facing‚ and booster – based on weight and height guidelines.
Rear-Facing Mode Guidelines
Rear-facing is the safest position for infants and toddlers‚ and the Evenflo Symphony allows for extended rear-facing use. Always ensure your child meets the minimum weight requirement for this mode‚ typically starting from 5 pounds.
Proper recline adjustment is crucial for optimal head and spine support. Utilize the recline indicator to achieve the correct angle. The harness straps must be positioned at or below the child’s shoulders. Regularly check the harness tightness; it should be snug enough that you cannot pinch any excess webbing at the shoulder.
Never place rear-facing car seats in front of active airbags. Continue rear-facing as long as your child hasn’t reached the height or weight limit specified in the manual‚ maximizing their protection during potential impacts.
Forward-Facing Mode Guidelines
Transitioning to forward-facing should only occur when your child exceeds the rear-facing height or weight limits‚ as indicated in this manual. Ensure the harness straps are correctly routed through the designated slots‚ positioned at or above the child’s shoulders.
Always use the top tether strap when forward-facing; it significantly reduces head excursion during a crash. Verify the tether is securely attached to the vehicle’s anchor point. Regularly check the harness tightness – a snug fit is essential.
Never allow your child to lean forward or side-to-side while restrained. Continuously monitor your child’s growth and adjust the harness height accordingly‚ maintaining proper strap placement for optimal safety.

Booster Mode Guidelines
Booster mode is appropriate when your child has outgrown the forward-facing harness restraints‚ meeting the minimum height and weight requirements detailed within this manual. The Evenflo Symphony functions as both a high-back and backless booster.

Always ensure the vehicle’s seat belt lies across your child’s upper thighs‚ not the stomach or neck. The shoulder belt should comfortably cross the center of the shoulder. Never allow the belt to cut into the face or neck.
Maintain proper positioning throughout the ride. Regularly check the belt fit as your child grows. A properly fitted seat belt is crucial for effective protection in a collision.

Maintenance & Cleaning
Regular inspection for wear and tear‚ alongside proper cleaning of the car seat cover‚ is vital for maintaining the Evenflo Symphony’s safety and longevity.
Cleaning the Car Seat Cover
Maintaining a clean car seat cover is crucial for hygiene and extending the product’s life. The Evenflo Symphony’s cover is typically removable and machine washable‚ offering convenience for parents. Always refer to the manual for specific washing instructions‚ as water temperature and detergent types can vary.
Before washing‚ ensure all buckles and straps are detached. Use a mild detergent and avoid bleach or harsh chemicals. After washing‚ allow the cover to air dry completely before reinstalling it onto the car seat frame. Never place the car seat frame itself in the washing machine. Spot cleaning with a damp cloth and mild soap is recommended for minor stains on the frame. Regular cleaning helps prevent the buildup of dirt and grime‚ ensuring a comfortable and safe ride for your child.
Inspecting for Wear and Tear
Regularly inspecting your Evenflo Symphony for wear and tear is vital for continued safety. Carefully examine the harness straps for any fraying‚ cuts‚ or weakening of the material.

Pay close attention to the LATCH connectors and seatbelt paths‚ ensuring they are free from debris and operate smoothly. If any damage is detected‚ discontinue use immediately. Even seemingly minor wear can compromise the car seat’s protective capabilities. Refer to the manual for replacement part information and contact Evenflo customer support if needed. Prioritize safety by proactively addressing any signs of deterioration.
Replacing Parts
Genuine Evenflo replacement parts are crucial for maintaining the safety and integrity of your Symphony car seat. Never use aftermarket or non-approved components‚ as they may not meet safety standards. Harness straps‚ buckles‚ and LATCH connectors are common parts requiring replacement due to wear or damage.
Contact Evenflo customer support or visit their website to order the correct replacement parts for your specific model and manufacturing date. Always follow the instructions in the user manual when installing new parts‚ ensuring a secure and proper fit. Do not attempt to repair damaged components – replacement is the only safe option. Maintaining a properly functioning car seat relies on using authentic parts.

Safety Features & Considerations
The Evenflo Symphony incorporates side-impact protection and energy-absorbing foam‚ prioritizing your child’s safety. Always adhere to expiration dates for optimal performance.
Side Impact Protection
The Evenflo Symphony is engineered with robust side impact protection features‚ designed to significantly reduce the risk of injury during a collision. This crucial safety element incorporates specially designed head restraints and energy-absorbing materials strategically positioned to shield your child’s head‚ neck‚ and torso.
These components work in tandem to distribute crash forces away from the child‚ minimizing the potential for serious harm. The car seat’s structural integrity‚ combined with the advanced side impact technology‚ provides an extra layer of security‚ particularly important in angled collisions. Regularly inspect the side impact components to ensure they remain securely in place and function as intended‚ contributing to a safer travel experience for your little one.
Energy-Absorbing Foam Construction
The Evenflo Symphony utilizes advanced energy-absorbing foam throughout its construction‚ a critical component in maximizing child safety during a vehicle impact. This specialized foam is strategically integrated into the headrest‚ seat shell‚ and harness straps‚ working to compress and dissipate crash forces before they reach your child.
This innovative design significantly reduces the peak forces experienced during a collision‚ minimizing the risk of serious injury. The foam’s composition and density are carefully calibrated to provide optimal protection across a range of impact scenarios. Regularly inspect the foam components for any signs of damage or compression‚ ensuring they maintain their protective capabilities and contribute to a secure ride for your precious passenger.
Understanding Expiration Dates
