Installation
1. Forward-Facing Harnessed Booster Installation (22-40 lbs)
For children weighing 22-40 lbs, use the 5-point harness system and secure the car seat using the vehicle's LATCH system and top tether.
- Place the car seat forward-facing in an appropriate vehicle seating position.
- Locate your vehicle's lower LATCH anchors and attach the car seat's LATCH connectors. Ensure a tight connection.
- Route the top tether strap over the vehicle seat and attach it to the vehicle's top tether anchor. Tighten the tether strap.
- Press down firmly on the car seat while pulling the LATCH strap to remove all slack. The car seat should not move more than 1 inch side-to-side or front-to-back at the belt path.

2. High-Back Booster Installation (40-120 lbs)
For children weighing 40-120 lbs, the car seat converts to a high-back booster, using the vehicle's lap and shoulder belt to secure both the child and the booster seat.
- Remove the 5-point harness system according to the instructions in the "Maintenance" section.
- Place the booster seat forward-facing in an appropriate vehicle seating position.
- Position your child in the booster seat.
- Route the vehicle's lap and shoulder belt through the designated belt guides on the booster seat.
- Ensure the shoulder belt lies flat across the child's shoulder and chest, and the lap belt is low on the hips, touching the thighs. The RightFit headrest technology will help auto-adjust the vehicle belt for a proper fit.
- Buckle the vehicle belt.

Operating Instructions
Adjusting the Headrest (RightFit Technology)
The RightFit headrest is designed to auto-adjust the vehicle belt path as you adjust the headrest height, ensuring a proper fit for your child as they grow.
- Locate the headrest adjustment lever, typically at the top or back of the headrest.
- Squeeze the lever and slide the headrest up or down until the shoulder belt (in booster mode) or harness straps (in harnessed mode) are at or just above your child's shoulders.
- Release the lever to lock the headrest in place.

Securing Your Child (Harnessed Mode)
- Place your child in the car seat.
- Bring the harness straps over your child's shoulders and buckle the chest clip at armpit level.
- Insert the two buckle tongues into the crotch buckle until they click.
- Pull the harness adjustment strap at the front of the seat to tighten the harness until it is snug against your child's body. You should not be able to pinch any slack at the shoulder.

Maintenance
Regular cleaning will help maintain the longevity and hygiene of your car seat.
- Seat Pad: The comfortable, padded seat pad is removable and machine-washable. Use cold water on a gentle cycle and tumble dry on low heat. Do not use bleach.
- Harness Straps: Wipe harness straps with a damp cloth. Do not machine wash or submerge harness straps in water, as this can weaken the webbing.
- Buckle: Clean the buckle by wiping with a damp cloth. If the buckle is sticky, rinse it under warm water without soap.
- Plastic and Metal Parts: Wipe plastic and metal parts with a mild soap and water solution.
Troubleshooting
If you encounter issues with your Evenflo Chase Plus car seat, refer to the following common solutions:
- Car Seat Feels Loose After Installation: Ensure LATCH connectors and/or vehicle belt are routed correctly and pulled tight. Press down firmly on the car seat while tightening. Check your vehicle's manual for specific LATCH weight limits.
- Harness Straps Are Difficult to Tighten/Loosen: Check for twists in the harness webbing. Ensure the harness adjustment strap is not obstructed. Clean the buckle if it feels sticky.
- Child's Head Slumps Forward: Recline the vehicle seat slightly if possible and safe to do so (check vehicle manual). Ensure the headrest is adjusted to the correct height for your child.
- Buckle Not Latching: Ensure both buckle tongues are fully inserted into the crotch buckle until you hear a click. Clean the buckle if debris is present.
