Harmony Juvenile Products recommends keeping your
child in a forward-facing car seat with a harness unl
they reach the top height or mass limit allowed by your
car seat’s manufacturer. Once your child outgrows the
forward-facing car seat with a harness, it’s me to travel
in a booster seat, but sll in the back seat.
Transport Canada recommends that children under the
age of 13 years be placed in the back seat of the vehicle
and away from acve front air bags.
According to accident stascs, CHILDREN ARE SAFER
WHEN PROPERLY RESTRAINED IN THE REAR SEATING
POSITIONS THAN IN THE FRONT SEATING POSITIONS.
Please study the secon “Vehicle seang posions”.
Many local police and re departments frequently hold
safety inspecon events to ensure that booster seats are
properly installed. Please contact your local emergency
services department to see if and when they oer this
service.
! DO NOT allow others to install or use this booster seat
unless they read and understand all the instrucons
and labels.
! DO NOT GIVE THIS BOOSTER SEAT to someone else
without also giving them this instrucon manual.
Addional instrucon manuals can be downloaded
directly from www.harmonyjuvenile.com.
! To ensure proper booster seat use, keep and store this
instrucon manual and refer to it when necessary.
! DO NOT LEAVE A BOOSTER SEAT UNSECURED IN YOUR
VEHICLE. In a collision, sharp turn or sudden stop, an
unsecured booster seat can injure other occupants.
Remove it or make sure that it is securely aached
with the vehicle seat belt or UAS, even when not in
use.

ENOUGH TO BURN THE CHILD IF LEFT IN THE SUN.

touch the surface of any metal or plasc parts before
pung your child in the booster seat. Cover the
booster seat with a towel or blanket when the vehicle
is parked in direct sunlight.
! Use ONLY the vehicle’s 3-point lap-and-shoulder belt
system when restraining a child in this booster seat.
