Learn how to adjust the Evenflo GoTime Sport Booster Car Seat for a safe and comfortable fit. Follow these steps for height and harness adjustments.
Quick answer
Adjust the GoTime Sport Booster by repositioning the headrest to match your child's shoulder height and ensuring the lap and shoulder belt lie flat across their body.
Why Proper Adjustment Matters
A booster seat that is not adjusted correctly can leave your child unprotected in a crash. The GoTime Sport is designed for children from 40 to 120 lb, 44 to 57 inches tall, and at least 4 years old. Getting the fit right ensures the vehicle seat belt works as intended.
Before You Start
Check your vehicle owner's manual for booster seat guidelines. The GoTime Sport uses the vehicle's lap and shoulder belt, not a harness, so proper belt routing is critical.
Step-by-step adjustment guide
- Position the booster on the vehicle seat: Place the GoTime Sport on a forward-facing vehicle seat with a lap and shoulder belt. Ensure the booster sits flat against the seat back. Common mistake: using a lap-only belt. The booster requires a shoulder belt.
- Adjust the headrest height: Lift or lower the headrest so the top is just above your child's shoulders. The shoulder belt should cross the middle of the shoulder, not the neck or arm. Checkpoint: the headrest should be at or above the child's shoulders, not below.
- Have your child sit properly: Your child should sit all the way back with their bottom against the seat back and knees bent over the seat edge. Common mistake: slouching or leaning forward, which reduces belt effectiveness.
- Route the lap belt: Pull the lap belt across the child's upper thighs, not the stomach. Buckle it and ensure it lies flat and snug. Checkpoint: the lap belt should be low on the hips, touching the thighs.
- Route the shoulder belt: Guide the shoulder belt through the belt guide on the side of the headrest. It should cross the chest and shoulder, not the face or neck. Common mistake: placing the shoulder belt under the arm or behind the back.
- Tighten and test the fit: Pull the shoulder belt to remove slack. Do a pinch test: at the collarbone, you should not be able to pinch any webbing. Final check: the belt stays tight and the child is comfortable. Recheck every ride.
