on the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the

your knee to push down on the
child restraint as you tighten
the belt.

retractor to make sure the
retractor is locked. If the
retractor is not locked, repeat
Steps 5 and 6.
SEATS AND RESTRAINTS
7. Before placing a child in the
child restraint, make sure it is
securely held in place. Refer to
your child restraint manufacturer
instructions.
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 0 83.
To remove the child restraint,
unbuckle the vehicle seat belt and let
it return to the stowed position.
