How to tighten the straps on Evenflo 4-in-1 car seat

After placing the child in the seat, it’s now time to tighten those straps around him.

The harness straps must fit snugly against your child’s body. There should be no slack on the straps when tightened correctly.

Just follow these steps and you will be able to safely achieve a snug-fitting harness that’s not too loose or too tight either.

Step 1. Insert both buckle tongues into the buckle.

Step 2. Pull up on the harness strap to check that the buckle tongues are fastened and to remove any slack from the webbing around the child’s legs.

How to store the UAS straps on Evenflo 4-in-1?

According to the car seat manual, not storing the LATCH/UAS straps can lead to serious complications such as strangulation or injuries. 

You must always store the unused LATCH/UAS straps, with all slack removed, in the storage areas on the sides of your seat. 

To do that, roll or fold the excess LATCH/UAS strap and secure it with a rubber band then store it in the designated area on the sides of the seat.
