6. 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.
Try to pull the belt out of the retractor to make sure
the retractor is locked. If the retractor is not locked,
repeat Steps 5 and 6.
7. Before placing a child in the child restraint, make
sure it is securely held in place. To check, grasp
the child restraint at the safety belt path and
attempt to move it side to side and back and forth.
When the child restraint is properly installed, there
should be no more than 2.5 cm (1 in) of movement.
If the airbags are off, the off indicator in the passenger
airbag status indicator will come on and stay on when
the vehicle is started.
If a child restraint has been installed and the on
indicator is lit, see If the On Indicator is Lit for a Child
Restraint under Passenger Sensing System on
page 2 65 for more information.
To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position.
