A. Before You Begin
Thank you for choosing this child restraint.The DJG family
is committed to creating child restraints with the most
comfort and convenience available today.
Remember,parents are a child’s first teachers and ex-
amples.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 child restraint will prevent
injury or death in a particular crash. However,when com-
bined with careful driving,proper use of a child restraint
can lower a child’s risk of injury or death in most crashes.
Your child’s safety is worth the time it will take to read and
follow these instructions.After reading, if you still have

C-12 Accessories on Select Models D-1 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 infor-
mation 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.
Use the center seating position if possible.
For vehicles without a back seat,refer to
your vehicle owner’s manual.
If you are not sure where to place the child restraint in your vehicle,
consult your vehicle owner’s manual,contact Dorel Juvenile Group
Consumer Care Department or visit your local Child Passenger
Inspection Station.Go to http://www.safercar.gov/cpsApp/cps/index.
htm to find your closest station.
Children are safer when prop-
erly restrained in rear seating
positions than in the front
seating positions.
According to National HighwayTraffic SafetyAdministra-
tion information, children in rear seating positions are
statistically safer,whether you have air bags,advanced air
bags,or no air bags at all.
To avoid your child being seriously burned, take the fol-
lowing precautions:
1. Park in the shade or where sun does not directly hit the child
restraint.
2. Cover the child restraint with a sheet or blanket when not in
use.
3. Check for hot seat and buckles before placing child in child
restraint.
To help protect your vehicle seat’s upholstery from damage, use
a single layer towel underneath and behind child restraint.
To Remove Head/Hip Roll
Undo the fastening strips and
pull the head/hip roll out from
behind the harness straps.
To Attach Head/Hip Roll:
Undo the fastening strips and
fit the head/hip roll behind
the harness straps.
Refasten the fastening strips.
For Smaller Infants
If your infant is small for its
age, place the head roll on the
outside of the pillows. This
will provide a snug fit for your
infant.
As your child grows, remove
the pillows.
For larger infants, the hip/
head roll/pillows can be
removed altogether.

The LATCH System
The lower anchors of LATCH (Lower Anchors andTeth-
ers for CHildren) is a universal system for installing child
restraints without using vehicle seat belts.
The lower anchor system can ONLY be used in vehicles that
have the lower anchor bars installed and designated LATCH
seating positions.
Most vehicles manufactured after September 2002 are
equipped with lower anchor bars.
Check your vehicle owner’s manual to see which seating
positions may be equipped with the LATCH system.
Lower Anchor Bars
Seat Bight
Your vehicle’s features may be considerably different than
those pictured here.
Vehicle Belts
If lower anchors are not an option,you must use the ve-
hicle seat belt system to install the child restraint.
There are some vehicle belts that will not work with a child
restraint or will require special attention.
Check your vehicle owner’s manual for specific instruc-
tions.
WARNINGS: When used correctly the lower anchor belt
or vehicle belts are equally safe. Do not use both the lower
anchor belt and vehicle belt at the same time.
Your vehicle’s features may be considerably different than
those pictured here.
D-2 Choosing Lower Anchor or Vehicle Belts

35 36
D. General Vehicle Information
1.You MUST ReviewYour
Vehicle Owner’s Manual
Your vehicle owner’s manual
will let you know what vehicle
belts and seating positions child
restraints can be installed in.
2. Determine How the Child
RestraintWill 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.
3. Check the Retractor
Retractors pull seat belts into
stored positions and lock the belt
to hold passengers in place.
A retractor is most likely how you
will be locking a child restraint into
place.
The ways this can be done are:
• By using the seat belt’s retractor; or
• By using the seat belt’s latch plate.
Not all vehicle belts and seating positions will work with
child restraints. Please follow the following steps to under-
stand how to lock a child restraint with a vehicle belt.
See the next page for some common types of vehicle belt retrac-
tors that will work with this child restraint.
D-3 Knowing Your Vehicle Belts
Switchable Retractor
(most vehicles have this type)
Automatic Locking Retractor
Emergency Locking Retractor
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 child restraint.
Switching to locking mode: Slowly pull the shoulder belt
all the way out,then let it go back in an inch or two.
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.
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
an inch or two.
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 the Latch Plates,” on next
page.

the Latch Plates,”

D. General Vehicle Information
D-4 Aircraft Information
This restraint is certified for aircraft use.
Install the child restraint in a window seat to
avoid blocking the aisle.If the aircraft lap belt
is too short,ask the flight attendant for a belt
extender.
Use only on forward facing aircraft seats.
Contact the airline for their specific policies.
Locking Latch Plate
Emergency Locking
Retractor with a
Sliding Latch Plate
4. Check the Latch Plates
Latch plates are the part of
the seat belt that goes into the
buckle.
Hold the lap belt with one hand
and with your other hand grasp the
tongue of the latch plate (the part
that goes inside the buckle).Pull
the latch plate straight out in line
with the lap belt.
If the latch plate does not slide up
and down the vehicle belt,it is a
locking latch plate.
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 por-
tions of the belt.
If you have an Emergency Lock-
ing Retractor with a Sliding Latch
Plate,you MUST use a locking clip
to install the child restraint.See
pages 52-54.

Some airlines may ask to see a
label stating that this child restraint

There is an airplane certification
label located on the back of this
child restraint as shown.
