Description

The Evenflo Big Kid Sport Booster Car Seat is engineered with both safety and comfort in mind. The high-back mode provides additional support and protection for younger children, while the backless mode offers more freedom as they grow older. The seat's ergonomic design ensures optimal positioning of the vehicle's seatbelt across the child's body, enhancing overall safety. Additionally, the cushioned headrest and side wings offer superior comfort during long car rides.

The seat also features a unique machine-washable pad that can be easily removed and cleaned, maintaining hygiene and freshness. The overall design is sleek and modern, blending well with most vehicle interiors.

How To Attach

Attaching the Seat Pad to the Base

1. Push the cup holders through the openings, one at a time.
2. Pull the seat pad down over the back of the cup holders.
3. Position seat facing up. Wrap the seat pad around the front of the seat. Make sure the seat pad is straight and positioned correctly on the seat.
4. Pull the rest of the seat pad down around the back of the seat, and attach to the hooks.

Assembling Backrest

1. Assemble the backrest. Insert three posts on the headrest into the backrest, as shown. Make certain the headrest locks securely into the backrest.
   Note: This is a one-time assembly and may require additional force to connect properly.
2. Install pull handle. Align tabs on pull handle with the slots on the back of the headrest. Press pull handle against the back of the headrest and slide upward until the tabs lock into place.

Attaching the Backrest Pad

Wrap the backrest pad around the back. Make sure the  pad is straight and positioned evenly on the seat.

1. Pull the headrest pad down over the top of backrest. Attach the headrest pad to the hooks.

   

2. Connect elastic loops to hooks  on the top of the headrest on both sides.
3. Connect elastic loops to hooks on the  middle of the backrest on both sides.

4. Pull the pad around the bottom corners and connect elastic loops to hooks.

   

Assembling Your Booster Seat

1. Install the backrest. Slide the backrest assembly into the base. Make certain the backrest locks into place.
2. Check your work. Inspect the booster seat to make sure that the headrest is securely attached to the backrest, the seat pad is hooked into place, and that the backrest assembly is securely locked into the base. Repeat any assembly steps as necessary.

When to Put Your Child in a Booster Seat

Booster seats raise the child up and help to position the vehicle lap and shoulder belt correctly. When the child is properly restrained in a booster seat, their risk of injury  in all types of crashes is reduced, as the lap and shoulder belt provides excellent restraint of both the upper and lower torsos. 
The child needs to sit properly within the vehicle seat belts. When the vehicle seat belt is buckled, the lap belt should be low on the hips, just touching the thighs, and the shoulder belt should lie across the middle of the shoulder.  If the child leans out or moves the belt behind the back or places it under the arm, it will not provide the intended restraint.   

There are a number of things to consider when deciding whether the child is ready to sit in a booster seat, including: the weight and height rating on their current child seat, the child’s own weight and height, their maturity, and the seating positions available in your vehicle.  
How is a booster seat used?
Using a booster seat is very similar to buckling yourself into the vehicle:

• Read the instruction manuals for both the booster seat and the vehicle before you start.
• Put the booster in the back seat in a location with a lap and shoulder belt. Never use a booster with only a lap belt, as this could cause serious injuries.
• After the child is in the booster, pull the lap and shoulder belt across him/her and buckle it.
• Check that the shoulder belt lies across the middle of the shoulder and that the lap belt is low on the hips, just touching the thighs.

How can you tell if your child is ready to transition to a booster seat?
You should consider using a booster seat if the following conditions apply:

• The child is mature enough to sit in the booster seat and not put the belts under their arm or behind their back.
• The child is approaching the weight or height limit of the child restraint they are currently using. (Even children who have not outgrown their toddler seat can benefit from the use of a booster seat, if it is used properly.)
• If you have a vehicle that does not have a tether anchorage but has lap/shoulder belts available in the back seat, a booster seat may provide better protection than an internal harness seat without the tether.

Using Your Booster Seat with the Backrest

Child Requirements

• Weight: 18 – 45.3 kg (40 – 100 lbs)
• Height: 112 – 145 cm (44 – 57 in.) and tops of the child’s ears are at or below the top of the booster seat headrest.
• Age: At least 4 years old

IMPORTANT: Once your child exceeds any of the size requirements above, you MUST discontinue use of this seat. Your child may be ready for use of the vehicle belt system only at this time.

Installation Checklist

1. Place the booster seat on the vehicle seat.
2. Set the child in the booster seat. Make sure the child’s back and bottom are flat against the back and bottom surfaces of the booster seat.

3. Adjust the back of the booster, if necessary. Adjust the backrest so the shoulder belt guides are level with the top of the child’s shoulders. This will cause the shoulder belt to properly lay midway between the child’s shoulder and neck (see Adjusting the Backrest, page “Adjusting the Backrest” on page 27).
   WARNING: The shoulder belt MUST NOT cross the child’s neck or fall off the child’s shoulder. If you can not adjust the shoulder belt to properly lay midway between the child’s shoulder and neck, try another seating location or do not use the booster seat. 

   

4. Secure the child and booster seat to the vehicle seat. Stretch the lap/shoulder belt across the child and fasten the buckle. Make certain the shoulder belt is threaded through the shoulder belt guide.
5. Check your work. Make sure the lap belt is stretched low and snug across the child’s hips, beneath the armrests (both Lap and Shoulder belts), and fastened into the buckle. The shoulder belt must cross the child midway between his/her shoulder and neck.
   IMPORTANT
   Always secure the booster seat with the vehicle seat belts when not occupied. An unsecured booster seat can fly into and injure other occupants in the event of a crash.

Safe Practices

• Everyone rides buckled up or the vehicle does not go. Make no exceptions for adults or children. If someone unbuckles, stop the vehicle.

• Put sharp or heavy items in the trunk. Anything loose can be deadly in a crash.
• Leather (not available on all models) can become very hot in direct sunlight. Cover your booster seat with a blanket in warm weather.
• In cold weather a child may need an extra blanket for warmth. Put the child in the booster seat and cover both the child and the booster seat with a blanket.
