Installation Guide
Secure installation is crucial; utilize either the LATCH system or vehicle seat belts‚ ensuring a proper fit and recline angle for optimal safety․
LATCH System Installation
Utilizing the LATCH (Lower Anchors and Tethers for CHildren) system offers a convenient and secure installation method․ Begin by locating the lower anchors in your vehicle’s seat bight – the space between the seat cushion and backrest․ Connect the Evenflo Symphony DLX Platinum’s lower anchor connectors‚ ensuring they click firmly into place․
The Symphony DLX features an EasyClick Latch system‚ providing simplified tightening․ After connecting the lower anchors‚ pull the LATCH strap to remove any slack‚ achieving a snug and stable fit․ Remember to also utilize the top tether strap when in forward-facing mode; this significantly reduces head excursion in a crash․ Verify the installation by firmly grasping the car seat near the belt path – it should not move more than one inch side-to-side or front-to-back at the belt path․
Belt-Installed Installation
When LATCH installation isn’t feasible‚ or vehicle manufacturer restrictions apply‚ utilize the vehicle’s seat belt system for secure installation․ Route the vehicle’s seat belt through the designated belt path on the Evenflo Symphony DLX Platinum car seat‚ following the diagram in the manual․ Ensure the belt lies flat and isn’t twisted․
To tighten the seat belt‚ push down firmly on the car seat while pulling the shoulder belt to remove any slack․ A locking latch plate is crucial for maintaining tightness; consult your vehicle’s manual to determine if your seat belts are locking latch plate type or switchable․ Always verify a secure installation by attempting to move the car seat side-to-side and front-to-back at the belt path – movement should be minimal (less than one inch)․
Proper Recline Angle Adjustment
Achieving the correct recline angle is vital for infant safety‚ ensuring the baby’s airway remains open․ The Evenflo Symphony DLX Platinum features adjustable recline positions․ For newborns and smaller infants in rear-facing mode‚ a more reclined position is necessary․ Consult the integrated recline indicator to confirm the appropriate angle is achieved; this indicator visually confirms correct positioning․
To adjust the recline‚ locate the recline mechanism‚ typically at the base of the car seat․ Follow the instructions in the manual to adjust to the desired angle․ Regularly check the recline angle as the child grows‚ adjusting as needed to maintain proper support and safety․ Incorrect recline can compromise the car seat’s protective capabilities․

Usage Instructions
The Evenflo Symphony DLX Platinum adapts to your growing child‚ offering rear-facing‚ forward-facing with harness‚ and booster modes for extended use․
Rear-Facing Mode (Weight & Age Limits)
Rear-facing is the safest position for your child as long as possible․ The Evenflo Symphony DLX Platinum allows for extended rear-facing use‚ accommodating infants and toddlers․ This mode is suitable for children weighing between 5 and 40 pounds‚ and with a height up to 40 inches․ Always ensure the harness straps are at or below the child’s shoulders when rear-facing․
Proper installation and recline angle are crucial for safety in this mode․ Refer to the installation guide for detailed instructions on achieving the correct recline․ Regularly check the harness tightness to ensure a snug and secure fit․ Never place the car seat in the front seat with an active airbag․ Prioritize rear-facing until your child reaches the maximum weight or height limit․
Forward-Facing Mode with Harness (Weight & Age Limits)
Transitioning to forward-facing should only occur when your child has reached the maximum rear-facing weight or height limit․ The Evenflo Symphony DLX Platinum supports forward-facing mode for children weighing between 22 and 50 pounds‚ and up to 57 inches in height․ Ensure the harness straps are at or above the child’s shoulders in this configuration․
Always utilize the top tether strap when forward-facing to minimize head excursion during a crash․ Double-check the installation’s security and recline angle․ Regularly inspect the harness for proper tightness and adjust as needed for growth․ Remember‚ keeping your child in a harnessed seat for as long as possible is the safest option before moving to a booster seat․

Booster Mode (Weight & Age Limits)
The Evenflo Symphony DLX Platinum transitions to a high-back booster seat when your child exceeds the forward-facing harness limits․ Booster mode is appropriate for children weighing between 40 and 100 pounds‚ and standing between 43 and 57 inches tall․ It’s crucial your child is mature enough to remain seated properly with the vehicle’s seat belt․
Always ensure the vehicle’s shoulder belt lies across the middle of your child’s shoulder and chest‚ and the lap belt rests low and snug across the upper thighs․ Never allow the shoulder belt to cross the face or neck․ Regularly check the belt fit as your child grows․ A properly fitted booster seat significantly enhances vehicle safety․

Adjusting the Harness and Headrest
Proper adjustment of the harness and headrest is vital for optimal safety and comfort as your child grows within the Evenflo Symphony DLX Platinum․
Harness Height Adjustment
Adjusting the harness height is crucial as your child develops to ensure proper shoulder positioning and maximum safety within the Evenflo Symphony DLX Platinum car seat․ Locate the harness adjustment slots behind the headrest; these allow for multiple height settings․
To raise the harness‚ simultaneously depress the red release buttons on both sides of the headrest and reposition it to the next higher set of slots․ Ensure both sides are adjusted to the same height․ Lowering the harness requires the same process‚ selecting a lower slot position․
The harness straps should always be at or 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 to maintain this correct positioning for optimal protection during every journey․
Harness Tightening and Loosening
Proper harness tightness is paramount for child safety in the Evenflo Symphony DLX Platinum․ To tighten the harness‚ pull the adjustment strap located at the child’s hips․ Continue pulling until the harness is snug – you should not be able to pinch any excess webbing at the child’s shoulder․
To loosen the harness‚ locate the same adjustment strap and press the red release button while simultaneously pulling on the strap․ This will release tension‚ allowing for easier adjustments․ Always re-tighten the harness after adjusting to ensure a secure fit․
Remember‚ a properly tightened harness minimizes forward movement in a crash․ Regularly check harness tightness‚ especially after adjusting the headrest or adding bulky clothing․
Headrest Adjustment
Adjusting the headrest on the Evenflo Symphony DLX Platinum is crucial as your child grows‚ ensuring optimal safety and comfort․ The headrest features multiple positions to accommodate varying heights․ To adjust‚ locate the adjustment lever – typically found at the back of the headrest․
Squeeze the lever and simultaneously raise or lower the headrest to the appropriate position․ Ensure the headrest is positioned so that the harness straps exit at or slightly above the child’s shoulders in forward-facing mode‚ and at or below the shoulders in rear-facing mode․
Regularly adjust the headrest to maintain proper harness positioning as your child develops․ A correctly adjusted headrest provides vital side-impact protection․

Maintenance and Cleaning
Regular maintenance ensures longevity and safety․ Clean the cover and harness routinely‚ inspect for wear‚ and replace damaged parts promptly for optimal performance․
Cleaning the Cover and Harness
Maintaining a clean car seat is crucial for hygiene and longevity․ The Evenflo Symphony DLX Platinum cover is typically removable and machine washable – always check the manual for specific fabric care instructions before washing․ Use a mild detergent and cold water‚ avoiding bleach or harsh chemicals․ Allow the cover to air dry completely before reinstalling it on the car seat base․
For the harness‚ gently hand wash with mild soap and water․ Avoid abrasive cleaners that could damage the webbing․ Rinse thoroughly and allow to air dry‚ ensuring all moisture is gone before use․ Regularly inspect the harness for any signs of fraying or damage‚ and replace it if necessary․ Proper cleaning extends the life of your car seat and ensures a safe‚ comfortable ride for your child․
