Choosing Car Seat Mode
5
Measure your child’s weight and height
(do not guess) before choosing the car seat’s mode.
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 of these
modes within the limits and fit requirements of the 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 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 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.
FORWARD-FACING MODE
22-65 lb (10.1-29 kg) and 29-49 in. (73.6-125 cm)

• Weight Limit: 65 lb (29 kg); OR
• Height Limit: 49 in. (125 cm); OR
• Forward-Facing Child Fit requirements, see page 10
REAR-FACING MODE
14-40 lb (6.4-18 kg) and 40 in. (101.6 cm) or less
Children under 1 year of age must ride Rear-Facing.
In this car seat, your child can remain Rear-Facing until
they outgrow any one of the following:

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.
Do not use both the lower anchor belt and vehicle belt
at the same time.

To Store Lower Anchor Belt
When using the vehicle belts to install
or when the car seat is not installed in

properly stored.
Thread the lower anchor belt through the
Rear-Facing Belt Path then attach the
connectors to the storage attachments as
shown. Gently tighten to remove slack.
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 steps following steps to understand
how to lock a car seat in Rear-Facing Mode or Forward-
Facing Mode with a vehicle belt.
Lap/Shoulder Belts

continued on next page
2019
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.
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.
Automatic Locking Retractor
Emergency 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).
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”.
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.

Retractor with a
Sliding Latch Plate
Emergency Locking Retractor Lap Only Belt
Inflatable Seat Belts
Never Use With This Car Seat
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.
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 61.
Your vehicle’s features may be considerably different
than those pictured here.
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.
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.
