3-14 Seats and Restraints
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 on
page 3 11.
To move it down, press the release
button (A) and move the height
adjuster to the desired position.
After the adjuster is set to the
desired position, try to move it down
without pressing the release button
to make sure it has locked into
position.
Safety Belt Pretensioners
This vehicle may have 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, near
frontal, side, or rear crash if the
threshold conditions for pretensioner
activation are met.
Pretensioners, if equipped, work
only once. If the pretensioners
activate in a crash, the
pretensioners and probably other
new parts of the vehicle's safety belt
system will need to be replaced.

Parts after a Crash on page 3 18.
