4. Setup and Installation
Follow these steps for secure installation of the accessory base in your vehicle. Always ensure your vehicle is parked on a level surface.
- Position the Base: Place the accessory base on the vehicle seat in the desired rear-facing position. Ensure it sits flat against the vehicle seat back and cushion.
- Engage LockStrong™ System: Route the vehicle's seat belt or LATCH connectors through the designated belt path on the base. Engage the LockStrong™ belt tensioning system to tighten the belt. This system is designed to provide a solid, secure installation.
- Check Indicators: Verify that the installation indicators on the base show a 'green' or 'secure' status. These indicators provide visual confirmation of proper installation. If the indicator is not green, re-adjust the belt tension until it is.
- Test for Movement: Once installed, firmly grasp the base at the belt path and attempt to move it side-to-side and front-to-back. The base should not move more than one inch (2.5 cm) in any direction.
- Attach Infant Car Seat: Refer to your Evenflo infant car seat manual for instructions on how to properly attach and secure the car seat to the installed accessory base.



5. Operating the Accessory Base
The accessory base is designed to simplify the transfer of your compatible Evenflo infant car seat between vehicles.
- Attaching the Car Seat: Align the infant car seat with the base and firmly press down until you hear an audible click, indicating it is securely latched. Always check the car seat's indicators (if applicable) to confirm proper attachment.
- Detaching the Car Seat: Locate the car seat release handle or button (typically on the car seat itself) and activate it while lifting the car seat upwards from the base.
- Vehicle Swapping: With an accessory base installed in each vehicle, you can quickly and easily move your infant car seat from one car to another without needing to reinstall the base each time.

- Cleaning: Clean the plastic parts of the base with mild soap and water. Do not use abrasive cleaners or solvents. Allow to air dry completely.
