5. To make the lap part tight, pull
up on the shoulder belt. To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
Always stow the safety belt slowly.
If the safety belt webbing returns
quickly to the stowed position, the
retractor may lock and cannot be
pulled out. If this happens, pull the
safety belt straight out firmly to
unlock the webbing, and then
release it. If the webbing is still
locked in the retractor, see your
dealer.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.
Shoulder Belt Height Adjuster The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger seating
positions.
Adjust the height so the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt
should be close to, but not
contacting, the neck. Improper shoulder belt height adjustment
could reduce the effectiveness of
the safety belt in a crash. See How
to Wear Safety Belts Properly 0 71 .
Press the release button and move
the height adjuster to the desired
position. The adjuster can be moved
up by pushing the slide/trim up.
After the adjuster is set to the
desired position, try to move it down
without pushing the release button
to make sure it has locked into
position.

Seats and Restraints 99Caution (Continued)restraint. Use the window lockout
button on the driver door to
prevent adjustment of the seat
whenever a child restraint is
installed.
CautionDo not let the LATCH
attachments rub against the
vehicle ’ s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.

child restraint in the rear seat, see

This system is designed to make
the installation of child restraints
easier. When using lower anchors,
do not use the vehicle's safety belts.
Instead, use the vehicle's anchors
and child restraint attachments to secure the restraints. Some
restraints also use another vehicle
anchor to secure a top tether.

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 safety belts. Move the head
restraint up if needed to get a
tight installation. Refer to your
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,
attach and tighten the top
tether to the top tether anchor,
if equipped. Refer to the child
restraint instructions and the
following steps:
2.1. Find the top tether anchor.
2.2. Open the top tether
anchor cover to expose
the anchor.
2.3. Route, attach, and tighten
the top tether according to
your child restraint
instructions and the
following instructions:
