3-56 Seats and Restraints
If the position you are using
has a fixed headrest or
head restraint and you are
using a single tether, route
the tether over the headrest
or head restraint. If the position you are using
has a fixed headrest or
head restraint and you are
using a dual tether, route
the tether around the
headrest or head restraint.

anchor (A). Make sure that
you secure the top tether to
the top tether anchor and
not to the seatback
latch (B).

seatback until it locks into
its upright position. Push

does not have lower

restraint with the top tether and
the safety belts. Refer to the
child restraint manufacturer
instructions and the instructions
in this manual.
