•

Use only in a rear-facing position when using restraint with

an infant weighing less than 20 pounds (9 kg). The American

Academy of Pediatrics recommends rear-facing until at least 1

year of age and 20 pounds.

•

Use only with children who weigh between 5 and 65 pounds

(2.3 and 29 kg) and whose height is 49 inches (124 cm) or

less. Rear facing 5–33 pounds (2.3–15 kg) and forward-facing

maximum 65 pounds (29 kg).

•

Snugly adjust the belts provided with this child restraint around

your child. A snug strap should not allow any slack. It lies in a

relatively straight line without sagging. It does not press on the

child’s flesh or push the child’s body into an unnatural position.

•

Secure the top anchorage strap provided with this child

restraint.

•

Secure this child restraint with the vehicle’s child restraint

anchorage system if available or with a vehicle belt.

•

Follow all instructions on this child restraint and in the written

instructions located on lanyard, under cover in front of seat.

•

Use vehicle belt (not LATCH connectors) for installations with

children weighing more than 48 pounds (21 kg). Refer to the

vehicle owner’s manual or contact the vehicle manufacturer for

the maximum weight rating for their LATCH anchors. Unless

specified otherwise by the vehicle manufacturer, assume a 48-

pound child is the vehicle LATCH anchor limit.

•

Discontinue use of a child restraint that is older than six years or

has been in a severe crash to prevent injury due to deterioration

or hidden damage.

•This child restraint must not be used in the home, in boats, or

other non-certified applications.

•

Based on crash statistics, the National Highway Traffic Safety

Administration recommends that parents select the rear seat

as the safest location for a properly installed child restraint.

Please study the section on Vehicle Safety Belts in this booklet

to ensure the child’s safety. If in doubt about installing the child

restraint, consult the vehicle owner’s manual.

•

Secure this child restraint even when it is not occupied. In a crash,

an unsecured child restraint may injure vehicle occupants.

•

When using in vehicle with air bags, refer to the vehicle

owner’s manual for child restraint installation instructions and

precautions.

•

Restraint must be in the full upright position when installed in

forward-facing mode with children over 33 pounds (15 kg).

•

Never use the adjuster strap to lift or carry this child restraint. Doing

so could cause damage to the harness adjuster and webbing.

Always carry this child restraint by the shell or tether straps.

•

The primary protection for occupants of a vehicle in a collision

is the structure of the vehicle itself; a child restraint will not

protect a child when the vehicle is seriously impacted. However,

correctly installed, a child restraint will substantially improve the

chances for survival in most crashes. Make sure that all users

fully understand the correct ways to use this child restraint in

a vehicle.

Safety Information

Safety Information

IMPORTANT

•

Verify that the child restraint is secure and that the harness is

properly adjusted around the child each time the child restraint

is used.

•

Adjust the harness to fit the clothes the child is wearing. The fit

for a child in winter clothes will differ from a child in summer

clothes.

•

Cover the restraint when the vehicle is parked in direct sunlight.

Parts of the child restraint could become hot enough to burn the

child.

•

Store the child restraint in a safe place when it is not being used.

Avoid placing heavy objects on top of it.

•

Do not leave children alone in a vehicle, even for a short time.

•

Do not, except as described in this booklet, attempt to disassemble

any part of the child restraint or change the way its harness or the

vehicle restraint belts are used.

•

Do not leave loose objects, e.g. books, bags, etc., in the back of

a vehicle. In the event of a sudden stop, loose objects will keep

moving, potentially causing serious injuries.

•

Do not leave folding vehicle seats unlatched. In the event of a

sudden stop, a loose seat back could prevent the child restraint

from protecting the child as well as it should.

•

Do not allow children to play with the child restraint.

•

Do not use anything to raise the restraint off the vehicle seat. In

an crash, it could slide and may not protect the child as well as it

should.

NOTE: The information in this section applies

only to installation with vehicle belts.

IMPORTANT: Some vehicles have no seating

positions which are compatible with this

child restraint, or any other child restraint. If

in doubt, contact the vehicle manufacturer

for assistance.

The following types of vehicle belts are not

compatible with this child restraint:

Front vehicle belts with top or bottom

anchorage points in the door.

Motor driven automatic vehicle belts.

Three-point belts that have separate

retractors for the shoulder section and

the lap section.

Non-locking (ELR) two-point vehicle

belts.

The owner's manual for your vehicle will

have information on the types of vehicle belts in your vehicle. If your

belt type is listed above, select another seating position or use LATCH

(Lower Anchors and Tethers for Children) connectors.

This child restraint can fit securely in most vehicles using the existing

vehicle belts. However, some types of vehicle designs prevent a secure

fit of the child restraint due to the position of the vehicle belt lower

anchorage points.
