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.

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 child restraints. Please
go through the following steps to understand how to lock a child restraint in
Forward-Facing Mode with a vehicle belt.
Vehicle Belts
continued on next page
Vehicle 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.
Check 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.
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.
1 2
15 16
continued on next page
Check
Retractor
Retractors pull
seat belts into
stored positions
and lock the belt
to hold passengers in place.
See the following section, for some
common types of vehicle belt
retractors that will work with this
car seat.
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
3
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).
If the retractor does not lock, it is most
likely an Emergency Locking Retractor.
These retractors only lock during a
sudden stop or collision.
Automatic Locking
Retractor
Emergency Locking
Retractor
See Step 4,
Check Latch
Plates.
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. Slowly pull up on
the lap portion of
the vehicle belt.
You will need to determine if your seat
belt’s latch plate can lock the belt. See
step 4, Check Latch Plates.

17 18
Emergency Locking
Retractor Lap Only Belt
Inflatable Seat Belts
Never Use With This
Car Seat
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.
Sliding Latch
Plate
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 60.
Tether Use
Your vehicle’s features may be
considerably different than those
pictured here.
Tether Anchors
For Forward-Facing
Mode Only
When anchors are available, you must alwaysattach, adjust, and secure the top anchorage (tether)
strap when installing the child restraint in the Forward-Facing Mode with internal harness. Tethers
improve the installation and stability of child restraints 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.
WARNING
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.
Serious injury can include paralysis and/or permanent brain injury.
DO NOT fasten multiple tether hooks on the same tether anchor in the vehicle.

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.
If one side of the harness is tighter than
the other, lengthen the tighter side by
pulling up the harness near the hip slot.

WARNING
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.
Vehicle Seating Position
According to accident
statistics, children are
safer when properly
restrained in the rear seating positions
than in the front seating positions.
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 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 https://www.nhtsa.gov/vehicle-safety/
car-seats-and-booster-seats to find your
closest station.
WARNING
To avoid your child being seriously
burned, take the following precautions:
• Park in the shade or where sun does
not directly hit the child restraint.
• Cover the child restraint with a sheet or
blanket when not in use.
• Check for hot seat and buckles before
placing child in child restraint.
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 LATCH belt
before each use. Use only if the belt
is tightened properly and locked
securely in place.
Even when unoccupied, this child
restraint MUST be firmly secured to the
vehicle with a 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.

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.
52
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 child restraint there is a date of manufacture
label as shown. DO NOT use this child restraint more than 10
years after the date of manufacture.

Troubleshooting
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 and it will be ready for next use.

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 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.
