To remove back pillow, loosen the
harness straps and slide pillow out
from behind the harness straps.
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.
Small Infant Positioning Pillow
Only For Use in Rear-Facing
Mode
When using the small infant
positioning pillow, you must also

This pillow helps position your infant in the seat in order to
achieve proper harness fit.
To determine if the pillow is needed:
1. Place headrest in lowest position.
2. Place infant in car seat without the pillow.
3. Make sure the infant’s bottom and back are flat against
the car seat.
Check often to see how much your infant has grown.

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.
Remove the infant pillow once they can sit in the car seat
without the infant pillow and the harness slots are at or
below their shoulders AND you can still achieve a snug
harness fit.
To remove, lift the infant pillow up and pull the buckle &
buckle cover down out of the buckle slot in the infant pillow.
To install, feed the buckle & buckle cover up into the 1st or
2nd buckle slot in the infant pillow, matching the buckle slot

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.

The lower anchors of LATCH (Lower Anchors and Tethers for
CHildren) is a universal system for installing car seats
without using vehicle seat belts. The LATCH: lower anchor
belt can ONLY be used in vehicles that have the lower
anchor bars installed in designated seating positions. Most
vehicles manufactured after September 2002 are equipped
with LATCH: lower anchor bars. Check your vehicle owner’s
manual to see which seating positions may be equipped with
LATCH: lower anchor bars.

To Store Lower Anchor Belt
The lower anchor belt MUST be properly stored in its
storage location when:
• using the vehicle belts to install the car seat; OR
• using the Booster Seat Mode; OR
• the car seat is not installed in a vehicle.
Secure the connectors to the attachments in the storage
location as shown. Gently tighten the belt to remove slack.
To Remove Lower Anchor Belt from
Vehicle’s Lower Anchor Bars
1. Remove the tension from the belt by pushing down on the
side of the car seat with the adjuster.
2. Then press the adjuster’s button to loosen the belt.
3. Press the release button on each connector, then pull the
connectors out of the vehicle seat.
DO NOT use both the lower anchor belt and vehicle belt at the same time.
WARNING:
53
54
You MUST Review Your
Vehicle Owner’s Manual
Your vehicle owner’s manual
will let you know which vehicle
belts and seating positions car
seats can be installed in.
1
Your vehicle’s features may be considerably different
than those pictured here.
If LATCH: lower anchors are not an option or if your child
weighs more than 40 lb (18 kg), you MUST use the vehicle
seat belt system to install the car seat.
Not all vehicle belts and seating positions will work
with car seats. Please go through the following steps to
understand how to lock a car seat in
Rear-Facing Mode
or Forward-Facing Mode with a vehicle belt.
Vehicle Belts
continued on next page
32
The vehicle belt MUST NOT
loosen after tightening.
This means there needs to be
a way to lock the vehicle belt.
The ways this can be done are:
• By using the seat belt’s
retractor (see step 3); OR
• By using the seat belt’s latch
plate (see step 4).
Retractors pull seat belts
into stored positions
and lock the belt to hold
passengers in place.
See the next page for
some common types of
vehicle belt retractors
that will work with
this car seat.
Check How This Car Seat Will Be Locked Into Place Check Retractor
55
56
Types of Retractors
Automatic Locking Retractor
This retractor always locks.
It will automatically lock after slowly
pulling the seat belt out at least halfway
and letting the belt go back into the
retractor 1-2 in. (2.5-5 cm).
Emergency Locking Retractor
See Step 4
“Check Latch Plates”
If the retractor does not lock, it is most
likely an Emergency Locking Retractor.
These retractors only lock during a
sudden stop or collision.
You will need to determine if your seat
belt’s latch plate can lock the belt. See
step 4, “Check Latch Plates”.
Switchable Retractor
(most vehicles have this type)
This retractor can be switched to a
locking mode.
You MUST have the retractor in the
locking mode to use the seat belt with
this car seat.
Switching to locking mode: Slowly pull
the shoulder belt all the way out, then let
it go back in 1-2 in. (2.5-5 cm).
As it goes back in, you will most likely
hear a ratcheting sound.
Gently pull the belt to see if it has
locked. You will not be able to pull any
more belt out if the lock has engaged.
continued on next page
Latch plates are the part of the seat belt
that goes into the buckle.
To see if the latch plate locks:
1. Buckle Vehicle Belt
2. Firmly Tug Lap Portion of Seat Belt
While Pulling It Up
If the vehicle belt does not slide through
the latch plate, it’s locked.
If the latch plate slides up and down the
vehicle belt, it is a sliding latch plate.
Sliding latch plates easily slip between
the lap and shoulder portions of the
belt.

Your vehicle’s features may be considerably different
than those pictured here.
When anchors are available, you MUST always attach,
adjust, and secure the tether (top anchorage) strap
when installing the car seat in the Forward-Facing Mode
with internal harness. Tethers improve the installation and
stability of car seats and reduce the risk of injury. Attach
the tether hook to the tether anchor designated by your
vehicle manufacturer for that seating position. Check your
vehicle owner’s manual for more information. If the seating
position does not have a tether anchor, use a different
seating position or see your dealer or a qualified mechanic
and have one installed.
Storing Top Tether Strap
The tether strap MUST be properly stored
in its storage location when:
• installing in Rear-Facing Mode; OR
• using the Booster Seat Mode; OR
• the car seat is not installed in a vehicle.
Attach the tether hook to its storage
location as shown. Gently tighten to
remove slack.
Top Tether
Using this child restraint without the tether strap
anchored as required by the manufacturer would be a
misuse of the child restraint and, in a sudden stop or
crash, could result in serious injury or death.
DO NOT fasten multiple tether hooks on the same
tether anchor in the vehicle.
WARNING:
Child Restraint Use
NEVER take your child out of the child restraint
while the vehicle is moving.
NEVER leave your child unattended. Placing your
child in a hot child restraint may result in burns.
DO NOT use a child restraint with damaged or
missing parts.
DO NOT use a child restraint with cut, frayed, or
damaged harnesses.
DO NOT substitute parts or try to modify the child
restraint in any way. DO NOT lubricate buckles
and fasteners.
DO NOT use any child restraint accessory except
those approved by Dorel Juvenile Group.
NEVER allow any child to play with this child
restraint; it is not a toy.
DO NOT remove or cover up any of the warning
labels or other labels on the child restraint.
This child restraint has been certified for use in
passenger vehicles. DO NOT use in a boat, on a
motorcycle or in a cargo van or bus where there
are no seat belts or tether anchors.
Read all instructions for additional warnings.
WARNING:
59
60
NEVER place a child rear-facing
in a seating position with an active
frontal air bag.
Check the vehicle owner’s manual for more
information about air bag/child restraint use.
Use the child restraint only on
vehicle seats that face forward.
DO NOT use on seats that face the
sides or rear of the vehicle.
For vehicles without a back seat,
refer to your vehicle owner’s manual.
Children are safer when
properly restrained in rear
seating positions than in the
front seating positions.
According to accident statistics, children in rear
seating positions are statistically safer, whether
you have air bags, advanced air bags, or no air
bags at all.
If you are not sure where to place the car seat in
your vehicle:
• Consult your vehicle owner’s manual; OR
• Contact Dorel Juvenile Group Consumer Care
Department; OR
• Visit your local Child Passenger Inspection Station. Go
to https://www.nhtsa.gov/equipment/car-seats-
and-booster-seats to find your closest station.
Vehicle Seating Position
WARNING:
Installation in Vehicle
Check the vehicle belt or lower anchor belt
before each use. Use only if the belt can be
tightened properly and locked securely in place.
Even when unoccupied, this child restraint
MUST be firmly secured to the vehicle with the
lower anchor belt or with the vehicle seat belt.
Even when unoccupied, this booster seat MUST
be firmly secured to the vehicle with the vehicle
seat belt.
In a crash or sudden stop, an unsecured child
restraint or booster seat could injure occupants.
To avoid your child being seriously burned, take
the following precautions:
• Park in the shade or where the sun does not directly
hit the car seat.
• Cover the car seat with a sheet or blanket when not
in use.
• Check for hot seat and buckles before placing child in
car seat.
To help protect your vehicle seat’s upholstery
from damage:

DO NOT risk your child’s safety.
To keep your child as safe as possible, Dorel Juvenile Group
strongly recommends replacing the car seat even after a minor
crash; even if it was not occupied at the time.
Replacement After a Minor Crash
The National Highway Traffic Safety Administration states
that for a crash to be considered minor ALL of the following
MUST be true:
• Vehicle able to drive away from the crash site; AND
• Vehicle door nearest the car seat was not damaged;
AND
• No passengers were injured; AND
• Airbags did not deploy; AND
• There is no visible damage to the car seat.
If the crash your car seat was involved in meets ALL the
criteria, you may not need to replace the car seat.
If one or more of these criteria are not true or if you are
uncertain of any of your answers, replace the car seat
immediately.
Replacement After a Moderate to Severe Crash
You MUST replace this car seat if it has been in a moderate
to severe car crash.
This car seat is intended to protect a child in a single crash.
During a crash, the car seat and all of its parts absorb crash
energy which can deform or weaken it. Damage is not always
visible. A damaged car seat MUST be replaced immediately.
Expiration
On the side of the car seat there is a date
of manufacture label as shown.
DO NOT use this car seat more than 10
years after the date of manufacture.
