2-52 Seats and Restraints
If the child restraint does not have
the LATCH system, you will be using
the safety belt to secure the child
restraint in this position. Be sure to
follow the instructions that came
with the child restraint. Secure the
child in the child restraint when
and as the instructions say.
If more than one child restraint
needs to be installed in the
rear seat, be sure to read Where
to Put the Restraint on page 2-43.
1. Put the child restraint on the seat.
2. Pick up the latch plate, and run
the lap and shoulder portions of
the vehicle's safety belt through
or around the restraint. The child
restraint instructions will show
you how.
3. Push the latch plate into the
buckle until it clicks.
If the latch plate will not go fully
into the buckle, check if the
correct buckle is being used.
Position the release button
on the buckle so that the safety
belt could be quickly unbuckled
if necessary.
4. Pull the rest of the shoulder belt
all the way out of the retractor to
set the lock.
