Your child’s height, weight, and age determine how the car seat
should be placed in the vehicle.
Children vary widely in body size, shape, and temperament—please
consult your doctor before switching between any modes within
the limits and fit requirements of the car seat.
State Laws
Please be certain to follow your state’s laws regarding car seat use.
American Academy of Pediatrics Recommendations
Infants and Toddlers
Should ride in a rear-facing car seat as long as possible, until they
reach the highest weight or height allowed by their car seat.
Toddlers and Preschoolers
Once they are facing forward, children should use a forward-facing car
seat with a harness for as long as possible, until they reach the height
and weight limits for their car seats.
School-Aged Children
Once they have outgrown their forward-facing car seat, children should
use a belt-positioning booster seat until the vehicle’s lap and shoulder
seat belt fits properly. This is often when they have reached at least 4
feet 9 inches in height and are 8 to 12 years old.
Older Children
All children younger than 13 years should be restrained in the rear
seats of vehicles for optimal protection.
Measure your child’s weight and height
(DO NOT guess) before choosing this car seat’s mode.

Failure to fasten and tighten the harness system correctly
may allow the child to be ejected from the child restraint in
a crash or sudden stop causing serious injury or death.
DO NOT mistake comfort for safety. The harness system
MUST be snugly adjusted.
DO NOT put snowsuits or bulky garments
on your child when placing them in the
child restraint.
Bulky clothing can prevent the harness
straps from being tightened properly.
To Remove Child from Car
Seat:
1. Loosen Harness Strap
2. Unbuckle Harness
3. Release Chest Clip
4. Remove Child
Troubleshooting
1. If the buckle or harness
release lever sticks: DO NOT
lubricate. Check for dropped
food, sticky spilled drinks, dirt,
leaves, etc.
Clean with warm water and/
or remove the object with
tweezers. If you cannot get the
harness to adjust and remain
tight with the buckle securely
locked, DO NOT use this car
seat.
2. If your harness twists:
Straighten the harness each
time you put your child in the
car seat. Lock the buckle and
tighten the harness so it will
be ready for next use.
WARNING:
FINISHED!
Your child is now secured in the car seat.
Check your child’s fit often and make any
needed adjustments to the car seat as they
grow.
Position Chest Clip
Pull the harness covers
down on the child.
Place the chest clip on the
lower part on the harness
cover so that the harness
covers are between your
child and the chest clip.
Position it at mid-chest
(even with armpits) and
away from your child’s neck.
Unfasten the harness covers.
Try to pinch the harness
at the shoulders vertically
between index finger and
thumb as shown.
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.
Check Harness
Tightness
If your fingers slip off, the harness is tight enough.
If you can pinch the harness strap, tighten more.
Fasten the harness covers.
