3Accessory Use
Removable Cup Holder
(on select models)
For Use in Rear-Facing
Mode or Forward-Facing
Mode
The cup holder is top-
rack dishwasher safe.
The cup holder can be attached
to either side of the car seat.
Pull the pad off the corner of the
car seat.
Align the symbol on the cup
holder with the symbol on the
car seat.
Hook the bottom of the cup
holder under the edge of the car
seat.
Snap the top of the cup holder
over the edge of the car seat.
Replace the pad.

Head Pillow
(on select models)
Only For Use in
Rear-Facing Mode
To remove, from the back of
the head pillow gently pull the
fabric tabs out of the shoulder
harness slots.
To attach, slide the fabric tabs
into the shoulder harness slots.
4
Harness Covers
(on select models)
For Use in Rear-Facing Mode or
Forward-Facing Mode
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 baby, remove
them and DO NOT use.
Store them 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.

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.
