REAR FACING
5-40 lb (2.3-18 kg)
19-40 in. (48-101.6 cm)
Children up to 1 year of age must ride rear facing.
The American Academy of Pediatrics recommends
that children remain rear facing until they are at
least 2 years old.
In this child restraint, your child can remain rear facing
up to 40 lb (18 kg) and up to 40 in. (101.6 cm).
FORWARD FACING
22-40 lb (10.1-18 kg)

The American Academy of Pediatrics recommends
that children remain in a five-point harness until
they outgrow their forward-facing harnessed child
restraint.
This typically occurs around age 4, but some children
outgrow them sooner and others not until later.

from the child’s neck.
6. Check Harness
Tightness
Try to pinch the
harness at the
shoulders vertically
between index finger
and thumb as shown.
If your fingers slip off, the harness is
tight enough.
If you can pinch the harness strap,
tighten more. The harness strap should
be snug throughout its length.
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.

WARNINGS: Failure to fasten
and tighten the harness system
correctly may allow the child to
be ejected from the child restraint

serious injury or death.
Do not mistake comfort for safety.
Harness system must be snugly
adjusted.
DO NOT put snow-
suits or bulky
garments on your
child when
placing them in the
child restraint.
Bulky clothing can
prevent the harness straps from

more information about air bag/child
restraint use.
Use the child restraint
only on vehicle seats
that face forward.

If you are not sure where to place the
child restraint in your vehicle, consult
your vehicle owner’s manual,contact
Dorel Juvenile Group Care Department
(see page 57),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
properly
restrained in
rear seating positions than in the
front seating positions.
According to National Highway
Traffic SafetyAdministration
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 following precau-
tions:
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.
Choosing Lower Anchor or Vehicle Belts
The LATCH System
The lower anchors of LATCH
(LowerAnchors andTethers
for CHildren) is a universal
system for installing child re-
straints 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.

When installing this child restraint with vehicle
belts, the lower anchor hooks and belt MUST be
properly stored.
Storing Lower Anchor Belt:
When used rear facing, thread lower anchor
belt through forward-facing belt path as shown.
Then attach hooks to attachments near rear-facing
belt path as shown. Gently pull free end of belt to
remove slack.
When used forward facing, thread lower anchor
belt through rear-facing belt path. Then attach
hooks to attachments near rear-facing belt path as
shown. Gently pull free end of belt to remove slack.
LowerAnchor
Hooks
Adjuster Vehicle Belts
If lower anchors are not an
option, you must use the
vehicle 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
instructions.
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.

31 32
Knowing Your Vehicle Belts
continued on next page
1.You MUST Review
Your 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 Restraint
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.
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 understand how to lock a child restraint
with a vehicle belt.
3. Check the
Retractor
Retractors pull seat
belts into stored
positions and lock
the belt to hold pas-
sengers in place.
A retractor is most likely how you will be
locking a child restraint into place.
See the following“Types of Retractors”
section for some common types of
vehicle belt retractors that will work with
this child restraint.
Switchable Retractor
(most vehicles have this type)
This retractor can be switched to a lock-
ing 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.
Types of Retractors

33 34
This retractor always locks.
It will automatically lock after slowly pull-
ing 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 sud-
den stop or collision.
Automatic Locking
Retractor
Emergency Locking
Retractor See Step 4
“Check the
Latch Plates”
Locking 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.
Emergency Locking
Retractor Lap Only Belt
Inflatable Seat Belts
Never UseWith This Child
Restraint
You will need to determine if your seat
belt’s latch plate can lock the belt. See
Step 4,“Check the Latch Plates.”
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 vehi-
cle belt,it is a sliding
latch plate.
Sliding latch plates
easily slip between
the lap and shoulder
portions of the belt.
If you have an Emer-
gency Locking Retrac-
tor with a Sliding Latch
Plate,you MUST use
a locking clip to install
the child restraint.See
pages 55-56.
