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

installed, there should be no
more than 2.5 cm (1 in) of
movement.

indicator in the passenger airbag
status indicator will come on and
stay on when the vehicle is started.

and the on indicator is lit, see If the
On Indicator Is Lit for a Child
Restraint under Passenger Sensing
System 0 73.
To remove the child restraint,
unbuckle the vehicle's safety belt
and let it return to the stowed
position.
