CAR SEAT USE AFTER A COLLISION

The U.S. National Highway Traffic Safety Administration (NHTSA) recommends that car seats be replaced following a MODERATE OR SEVERE COLLISION in order to ensure a continued high level of collision protection for child passengers.
Car seats do not automatically need to be replaced following a MINOR collision.
NHTSA defines a MINOR collision as ALL of the following:

• The vehicle was able to be driven away from the collision site;AND
• The vehicle door nearest the car seat was not damaged;AND
• No vehicle occupants were injured;AND
• There is no visible damage to the car seat;AND
• The airbags (if present) did not deploy.

NEVER use a car seat that has been involved in a MODERATE OR SEVERE COLLISION.

VEHICLE SEATING LOCATIONS

The safest seating position is one that works best for your specific child restraint, family and vehicle model.
Before installing this child restraint you must determine the method of installation and the best vehicle seating position for that method.
When determining whether the child restraint can be used with vehicle LATCH anchors in the rear center seating position, it is critical that you refer to your vehicle owner's instruction book. If the child restraint does not install best in the rear center seating location, it is recommended to move to one of the outboard seating positions.

2. Attach the backrest hooks to seat mounting points.
   
3. Push down on seatback just above hooks until fully engaged.
   
4. Rotate seatback to an upright position while maintaining pressure just above the hooks. Finish by tucking any excess fabric up and under the fabric of the backrest.
   

INSTALLATION

Unsecured objects can become flying hazards and can cause serious injury in an accident. If your vehicle is equipped with lower anchors, Diono always recommends installation utilizing the LATCH connectors with this booster seat.

To improve safety and performance, this booster seat is equipped with a lower anchorage system that allows secure attachment to a vehicle's lower anchor locations.

1. Disengage LATCH connectors from storage slots and lay booster seat on its side. While depressing the cam lock lever, pull LATCH connectors away from the booster seat and extend both straps all the way. Do not overextend connector straps.
   
2. Attach both LATCH connectors to the vehicle anchors, starting with the connector that is furthest from you. For ease of use, make sure open end of hooks face upward during use.
   
3. While pushing booster against vehicle seat, pull one adjuster strap tight and then the other. Make sure that both LATCH connectors are securely attached to the vehicles lower anchors.
   

NOTE: Even with LATCH connectors properly attached and adjusted, child seat will still have movement against the vehicle seat back and bottom.

Do not use LATCH if installation interferes with vehicle seat belt.

When using booster seat in center seating position, make sure it is stable and does not rock from side to side.

ADJUSTING THE RECLINE ANGLE
This booster seat features a recline angle that can be adjusted to match that of the vehicle seat:

1. Push booster seat backrest backwards until you hear a click. Backrest will now pivot freely and does not need to click into another position.
   
2. Push seat bottom and backrest of booster seat down and back into vehicle seat until there is secure positioning with the booster seat and vehicle seat bottom and vehicle seat back. A gap is acceptable as long as the head support is touching the vehicle seat back or head rest.
   

It may also be necessary to adjust the recline angle of the booster seat to match that of the vehicle seat.

LOWER ANCHOR REMOVAL & ADJUSTMENTS

DISENGAGING LOWER ANCHOR INSTALLATION
Follow the previous instructions in reverse order.

1. Reach under the bottom of the booster seat and depress the cam lock lever while pulling the seat away from the vehicle seat back until the lower anchor straps are extended all the way.
2. Disconnect LATCH connectors from vehicle anchors.
3. Pull lower anchor adjuster straps to recess the LATCH connectors into the back of the booster seat bottom for safe storage.

Do not use LATCH if installation interferes with vehicle seat belt.

ADJUSTING THE HEAD SUPPORT
The head support height can be adjusted for best fit to your child and to ensure proper placement of the Vehicle Shoulder Belt. Squeeze the head support adjustment lever on the back of the booster seat while adjusting its height up or down to fit the child.

ADJUSTING BACKREST WIDTH
To adjust the width of the seat back, turn the dial on the back of the backrest clockwise to increase width. Turn counterclockwise to make the backrest narrower.
NOTE: It may be easier to adjust backrest width prior to securing the booster seat installation using LATCH.

SECURING THE CHILD

Use ONLY the lap and shoulder belt system when restraining the child in this booster seat. DO NOT use lap belt only.

1. Place booster seat on vehicle seat so it is resting firmly on vehicle seat bottom and touching the vehicle seat back. A gap is acceptable as long as the head support is touching the vehicle seat back or head rest.
   
2. Properly position child: sitting upright and seated all the way back in the booster seat.
   
3. Adjust head support to proper height: The RED shoulder belt guide should be slightly above the child's shoulders (at least 1 cm). Squeeze the head support adjustment lever on the back of the booster seat while adjusting it's height up or down to fit the child.
   
4. Feed the vehicle diagonal shoulder belt portion of the seat belt through the RED shoulder belt guide into the side of the seat opposite the seat belt buckle.
   
5. Fasten vehicle seat belt across child. The lap portion of the seat belt should rest within both lower belt guides. The diagonal shoulder belt portion should route inside the lower belt guide closest to the buckle and over child's shoulder.
   
6. Make sure the vehicle seat belt is not twisted and lays flat across child's lap, torso and shoulder.
   
7. Tighten the seat belt by pulling the diagonal shoulder belt portion in the direction of the arrows.
8. Confirm seat belt buckle is in correct position.

The Vehicle Shoulder Belt MUST route completely through the RED shoulder belt guide and not fall off the child's shoulder.

DO NOT position the Vehicle Lap Belt over the armrest. It MUST pass under the armrest.

When using the diagonal portion of the seat belt, it should lay over the shoulder and should NOT be touching the child's neck.

PROPER BUCKLE POSITION

After booster seat is installed and seat belt is fastened around child, it is important to confirm correct seat belt buckle position to ensure secure installation.

CORRECT SEAT BUCKLE POSITION
Buckle is on the outside of lower belt guide.

INCORRECT SEAT BUCKLE POSITION
If buckle is being pulled across the lower belt guide and into the seat, choose another seating position within the vehicle.

BACKLESS BOOSTER SEAT

While this booster seat is designed to offer advanced side-impact protection with its backrest section attached, the seat bottom can also be used alone as a backless booster.

1. Remove the seat back by reversing the steps shown in "Seat Assembly."
2. Make sure both LATCH connectors are securely attached to the vehicles lower anchors (see "Lower Anchor Installation"). While pushing booster against vehicle seat, pull the adjuster straps tight.
   
3. Place booster seat on vehicle seat so it is resting firmly on vehicle seat bottom and touching the vehicle seat back. The entire seat bottom should sit flat on the vehicle seat.
   Properly position child: sitting upright and all the way back in the booster seat.
4. Fasten seat belt across child.
5. Make sure seat belt is not twisted and lays flat across child's hips, torso and shoulder.
   
6. Tighten the seat belt by pulling the diagonal shoulder belt portion in the direction of the arrows.

NEVER position the shoulder belt loosely or under the child's arm or behind their back.

USING THE SHOULDER BELT GUIDE STRAP

1. Remove shoulder belt guide strap from storage area underneath seat.
2. Position child correctly in seat as per the prior instructions in the manual, making sure lap and shoulder belts are positioned properly across child.
3. Attach the red shoulder belt guide strap onto the diagonal shoulder belt.
4. Adjust strap to correct length, so that the red guide is just above shoulder.
   

If the diagonal seat belt portion does not correctly fit the child, then the seat must be used with the shoulder belt guide strap or with the seatback portion attached and properly adjusted to fit the child.

CUP HOLDERS

Cup holders are located on both sides of the seat bottom.
Swivel outward to the locked position for use.
Swivel inward to the recessed and locked position when not in use.

DO NOT use with hot liquids as this could burn a child.

Do not step on or put excess weight on the cup holder which could cause it to break.
