Setup and Installation
Proper installation is crucial for the safety of your child. The Evenflo Gold SensorSafe SecureMax Smart Infant Car Seat can be installed using either the LATCH system or the vehicle's seat belt. Always refer to your vehicle's owner's manual for specific instructions regarding car seat installation points.
Harness Adjustment
The car seat features an easy-to-adjust, no-rethread harness system. To adjust the harness height, simply pull up on the headrest. Ensure the harness straps are at or below your child's shoulders when rear-facing.

SafeZone Load Leg Technology
The car seat base includes SafeZone Load Leg Technology for enhanced stability. This load leg extends to the vehicle floor, reducing rotation in the event of a frontal collision. Ensure the load leg is properly extended and locked into position according to the indicators on the base.

Operating the SensorSafe Smart Chest Clip
The SensorSafe smart chest clip and wireless receiver connect to an app on your phone, providing real-time updates on your child's comfort and well-being. This system is designed to alert you to potential safety concerns.
SensorSafe Alerts
- Unbuckled Alert: Notifies you if your child unbuckles themselves from the car seat.
- Temperature Alert: Alerts you if the car seat environment becomes too warm.
- Movement Alert: Informs you if your child has spent too much time without movement in the car seat.
Ensure the SensorSafe app is installed on your smartphone and properly paired with the car seat's receiver for these features to function.

Maintenance
Regular cleaning and maintenance will help prolong the life of your car seat. Refer to the care labels on the fabric for specific washing instructions. Typically, fabric covers can be machine washed on a gentle cycle with cold water and mild detergent, then air-dried. Plastic and metal parts can be wiped clean with a damp cloth and mild soap. Do not use abrasive cleaners or solvents.
Removable Inserts
The car seat includes removable inserts for custom comfort and fit, especially for newborns. These inserts can be removed as your child grows. Follow the same cleaning instructions for the inserts as for the main fabric cover.

Troubleshooting
If you encounter issues with your Evenflo Gold SensorSafe SecureMax Smart Infant Car Seat, please review the following common troubleshooting tips:
- SensorSafe App Not Connecting: Ensure your smartphone's Bluetooth is enabled and the SensorSafe receiver is properly plugged into your vehicle's OBD2 port. Restart the app and try re-pairing.
- Harness Difficulty: If the harness is difficult to tighten or loosen, check for any twists in the straps or obstructions in the harness path. Ensure the chest clip is positioned at armpit level.
- Car Seat Wobbles After Installation: Recheck the installation method (LATCH or seat belt) to ensure it is tight and secure. The car seat should not move more than one inch side-to-side or front-to-back at the belt path. Ensure the load leg is fully extended and locked.
