Special BabySmart
TM compatible child 
seats, designed for use with the

Infants and small children should never 
share a seat belt with another occupant. 
During an accident, they could be crushed 
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is 
significantly increased if the child restraints 
are not properly secured in the vehicle and 
the child is not properly secured in the child 
restraint.
Adjust the passenger seat as far as possible 
rearward from the dashboard when the seat 
is occupied.
Warning!
G
Children too big for child restraint systems 
should use regular seat belts. Position the 
shoulder belt across chest and shoulder, not 
face or neck. A booster seat may be neces-
sary to achieve proper belt positioning for 
children from 41 lbs. until they reach a 
height where a lap/shoulder belt fits proper-
ly without a booster.
When the child restraint is not in use, re-
move it from the vehicle or secure it with the 
seat belt to prevent the child restraint from 
becoming a projectile in the event of an ac-
cident.
Do not leave children unattended in the ve-
hicle; even if the children are secured in a 
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause serious 
personal injury.
