temperament—please consult your doctor before
switching between any types or modes of a car seat
within the limits and fit requirements of the seat.

(1.8-13.6 kg) and 32 inches (81.3 cm) or less in height.
NEVER leave child unattended. Always keep child within
arm’s reach.
Suffocation Hazard: Infant carrier can roll over on soft
surfaces and suffocate child. NEVER place
carrier on beds, sofas or other soft surfaces.
Strangulation Hazard: Children have STRANGLED in
loose or partially buckled harness straps. Fully restrain the
child even when carrier is used outside the vehicle.
Fall Hazard: Child’s activity can move carrier. NEVER
place carrier on counter tops, tables,
or any other elevated surface.
The carrier can fall from the shopping
cart. Do not use on shopping cart.

Adjustment Strap Loop
to Shell

If you can pinch the harness strap, tighten more.
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.

on your child when placing them in the child
restraint. Bulky clothing can prevent the
harness straps from being tightened properly.

LATCH: Lower Anchor Use
Your vehicle’s features may be considerably different
than those pictured here.
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.

When used correctly the lower anchor belt or vehicle belts
are equally safe.

To Remove Lower Anchor Belt
from Vehicle Lower Anchor Bars:
Press the red release button on each
connector, then pull the connectors out
of the vehicle seat bight.
To Store Lower Anchor Belt:

Vehicle Belts
Your vehicle’s features may be considerably different
than those pictured here.
If lower anchors are not an option, 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 with a vehicle belt.
Lap/Shoulder Belts

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.
Determine How This
Car Seat Will Be Locked
Into Place
The vehicle belt must not
loosen after tightening. This
means there needs to be a
way to lock the vehicle belt.
• By using the seat belt’s retractor (see step 3); OR
• By using the seat belt’s latch plate (see step 4).
The ways this can be done are:

63
3
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.
Types of Retractors
Check Retractor
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.

64
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
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”.
See Step 4, “Check Latch
Plates”.

4
Locking Latch Plate
Check Latch Plates
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.
65

66
Emergency Locking
Retractor with a
Sliding Latch Plate
Sliding latch plates easily slip
between the lap and shoulder
portions of the belt.
If you have an Emergency
Locking Retractor with a
Sliding Latch Plate, you must
use a locking clip.
Please contact us for one.
See page 81.
Never Use the Following With
This Car Seat:
• Emergency Locking Retractor Lap Only Belt
• Inflatable Seat Belts

Replacement and
Expiration of Car Seat
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 back of the car seat there is
a date of manufacture label as
shown.
Do not use this car seat more than 8
years after the date of manufacture.

71
WARNING:
Vehicle Seating
Position
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.

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.

continued on next page
72
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.

73
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: you may use an accessory approved by Dorel
Juvenile Group or a single layer towel underneath and
behind car seat.
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.
In a crash or sudden stop, an unsecured child restraint
could injure occupants.
Installation in Vehicle
WARNING:

1. If the child restraint buckle or harness release lever
sticks or you cannot get the straps tight enough around
child:
DO NOT LUBRICATE. Check around lever and retractor for
dropped food, sticky spilled drinks, dirt, leaves, etc. Clean
with warm water and/or remove object with tweezers. If you
cannot get the harness to adjust and remain tight with the
buckle securely locked, do not use the child restraint.
2. If your harness twists:
Straighten the harness each time you put your child in the
child restraint to help prevent twisting. Lock the buckle and
tighten harness so it will be ready for next use.

Thank you for choosing this car seat, also known as a child
restraint. The DJG family is committed to creating car seats
with the most comfort and convenience available today.
Remember, parents are a child’s first teachers and examples.
If you always buckle your seat belt, your child will think it is
the natural thing to do. Make it a firm rule that the vehicle
does not go until everyone is buckled up. Make no exceptions.
No one can predict if use of a car seat will prevent injury or
death in a particular crash. However, when combined with
careful driving, proper use of a car seat can lower a child’s
risk of injury or death in most crashes.
If you have questions or any concerns with this car seat,
please contact our Consumer Care Department:
