Seats and Restraints 73
{Warning
To reduce the risk of serious or fatal
injuries during a crash, do not attach
more than one child restraint to a single
anchor. Attaching more than one child
restraint to a single anchor could cause
the anchor or attachment to come loose
or even break during a crash. A child or
others could be injured.
{Warning
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck. The shoulder belt can
tighten but cannot be loosened if it is
locked. The shoulder belt locks when it is
pulled all the way out of the retractor.
It unlocks when the shoulder belt is
allowed to go all the way back into the
retractor, but it cannot do this if it is
wrapped around a child’s neck. If the
shoulder belt is locked and tightened
around a child’s neck, the only way to
loosen the belt is to cut it.(Continued)
Warning (Continued)
Buckle any unused seat belts behind the
child restraint so children cannot reach
them. Pull the shoulder belt all the way
out of the retractor to set the lock, and
tighten the belt behind the child restraint
after the child restraint has been
installed.
Caution
Do not let the LATCH attachments rub
against the vehicle’s seat belts. This may
damage these parts. If necessary, move
buckled seat belts to avoid rubbing the
LATCH attachments. Do not fold the rear
seatback when the seat is occupied. Do
not fold the empty rear seat with a seat
belt buckled. This could damage the seat
belt or the seat. Unbuckle and return the
seat belt to its stowed position, before
folding the seat.
If you need to secure more than one child
restraint in the rear seat, see Where to Put
the Restraint 068. 1. Attach and tighten the lower
attachments to the lower anchors. If the
child restraint does not have lower
attachments or the desired seating
position does not have lower anchors,
secure the child restraint with the top
tether and the seat belts. Refer to the
child restraint manufacturer instructions
and the instructions in this manual.
1.1. Find the lower anchors for the desired seating position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments on the child restraint
to the lower anchors.
2. If the child restraint manufacturer recommends that the top tether be
attached, adjust the top tether to its full
length and attach it to the anchor. Refer
to the child restraint instructions and the
following steps:
2.1. Find the top tether anchor.
2.2. Route, attach and tighten the top tether according to your child
restraint instructions and the
following instructions:
