Kia Rio 2006 Owner's Manual page 48

We strongly recommend that the driver and all
passengers be properly restrained at all times by
using the safety belts provided with the vehicle.
Proper use of the safety belts decreases the risk of
severe injury or death in accidents or sudden
stops. In most states, and in Canada, the law
requires their use.
Inertial locks in the safety belt retractors allow all of
the lap/shoulder safety belts to remain unlocked
during normal vehicle operation.
This allows the occupants some freedom of move-
ment and increased comfort while using the safety
belts. If a force is applied to the vehicle, such as a
strong stop, a sharp turn, or a collision, the safety
belt retractors will automatically lock the safety
belts.
Since the inertial locks do not require a collision to
lock up, you may become aware of the safety belts
locking while braking or going around sharp
corners.
Whenever possible, use the center rear seat posi-
tion to install your child restraint. The center rear
seat is the safest position for a child to sit in. If the
center seat is unavailable, a child restraint system
may be installed in an outboard rear seat position.
Never install a rear-facing infant seat in the front
passenger position, as an inflating air bag could
cause serious or fatal injury to a child in that posi-
tion.
