5. To make the lap part tight, pullup 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
front outboard 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 059.
Press down on 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.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety
belts during the early stages of a

Seats and Restraints 89
{Warning
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
To reinstall the head restraint:
1. Insert the head restraint posts into the holes in the top of the
seatback. The notches on the
posts must face the driver side
of the vehicle.
2. Push the head restraint down.
If necessary, press the height
adjustment release button to
further lower the head restraint.
See Head Restraints 050.
3. Try to move the head restraint to make sure that it is locked in
place.
Replacing LATCH System
Parts After a Crash
{Warning
A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint,
resulting in serious injury or even
death in a crash. To help make
sure the LATCH system is
working properly after a crash,
(Continued)
Warning (Continued)
see your dealer to have the
system inspected and any
necessary replacements made as
soon as possible.
If the vehicle has the LATCH system
and it was being used during a
crash, new LATCH system parts
may be needed.
New parts and repairs may be
necessary even if the LATCH
system was not being used at the
time of the crash.
Securing Child Restraints
(Rear Seat)
When securing a child restraint in a
rear seating position, study the
instructions that came with the child
restraint to make sure it is
compatible with this vehicle.
If the child restraint has the LATCH
system, see Lower Anchors and
Tethers for Children (LATCH
System) 082 for how and where to
