To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
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
belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger 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 3‑25.
Squeeze the buttons (A) on the
sides of the height adjuster and
move the height adjuster to the
desired position.
The adjuster can be moved up just
by pushing up on the shoulder belt
guide.
After the adjuster is set to the
desired position, try to move it
down without squeezing the buttons
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, near frontal, or rear crash
if the threshold conditions for
pretensioner activation are met.
And, if the vehicle has side impact
airbags, safety belt pretensioners
can help tighten the safety belts in
a side crash or a rollover event.
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.

Parts After a Crash on page 3‑38.
