Vehicle Seating Position
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 properly
restrained in rear seating
positions than in the front seating
positions.
According to National Highway Traffic Safety Administra-
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
following precautions:
1. Park in the shade or where sun does not directly hit the
booster seat.
2. Always use the booster seat with the seat pad.

Troubleshooting

hands on training on how to use your booster seat:
Visit your local Child Passenger Inspection Station or go to
http://www.safercar.gov/cpsApp/cps/index.htm to find your
closest station.
WARNING: NEVER place the shoulder belt behind

Thank you for choosing this booster seat.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.
No one can predict if use of a child restraint will prevent
injury or death in a particular crash. However,when
combined with careful driving,proper use of a booster seat
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
questions or have any concerns with this booster seat,
