Harness Covers (on select models)
For Use in Rear-Facing Mode or Forward-
Facing Mode
The harness covers help provide comfort to your
child’s neck.
If the harness covers will not allow proper positioning
of the chest clip or interfere with getting a tight
enough harness fit for a smaller infant, remove and
do not use. Store until your child is large enough to use the harness
covers while maintaining a properly fitting harness.
To remove, pull the fastening strips apart and pull the harness covers
off of the harness straps.
3Accessory Use
Body Pillow (on select models)
For Use in Rear-Facing Mode Only
To remove, slide it out from behind the harness
straps.
Removable Cup Holder(s) (on select models)
For Use in All Modes
The cup holder(s) is top-rack dishwasher safe.
To remove cup holder, twist the cup
holder counterclockwise. Pull it out of the
slot in the car seat.
Buckle Cover (on select models)
For Use in Rear-Facing Mode or
Forward-Facing Mode
To remove, undo the buckle and pull
the buckle cover off of the buckle.

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.
