5. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the
lap portion of the belt, and feed the shoulder
belt back into the retractor. When installing a
forward-facing child restraint, it may be helpful to
use your knee to push down on the child restraint as
you tighten the belt.
If the child restraint has a top tether, follow the child
restraint manufacturer's instructions regarding the
use of the top tether. See Lower Anchors and
Tethers for Children (LATCH) on page 1-43.
6. Push and pull the child restraint in different
directions to be sure it is secure.

To remove the child restraint, unbuckle the vehicle safety
belt and let it return to the stowed position. If the top
tether is attached to a top tether anchor, disconnect it.
Securing a Child Restraint in the
Right Front Seat Position
This vehicle has airbags. A rear seat is a safer place to
secure a forward-facing child restraint. See Where to
Put the Restraint on page 1-42.
In addition, the vehicle has a passenger sensing system
which is designed to turn off the right front passenger
frontal airbag under certain conditions. See Passenger
Sensing System on page 1-64 and Passenger Airbag
Status Indicator on page 3-36 for more information,
including important safety information.
A label on the sun visor says, "Never put a rear-facing
child seat in the front." This is because the risk to
the rear-facing child is so great, if the airbag deploys.
