decelerates or accelerates rapidly in a
lateral direction on the side opposite to the
impact.
R in certain situation swhere the vehicle rolls
over if the system determines that it can
provide additional protection.
If the ETDsa re deployed, you will hear abang,

Child restraint systems
Important safety notes G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible.R egardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchor sand
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children ,should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child. 56
