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. SeeHow
to Wear Safety Belts Properly on
page 3‑14.
Press the release button (A) 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
moderate to severe frontal and near
frontal crash if the threshold
conditions for pretensioner
activation are met.
Pretensioners work only once. If the
pretensioners activate in a crash,
the pretensioners and probably
other parts of the vehicle's safety
belt system will need to be replaced.

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,
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) on page 3‑44 for how and
where to install the child restraint
using LATCH. If a child restraint is
secured in the vehicle using a
safety belt and it uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) on
page 3‑44 for top tether anchor
locations.
