Squeeze both sides of the release button
and pull outward. Then move the height
adjuster up or down to the desired position
and release the button.
After the adjuster is set to the desired
position, try to move it up or down without
squeezing the release button to make sure it
has locked into position.
Seat Belt Pretensioners
If the vehicle has seat-mounted side impact
airbags and roof-rail airbags, it also has seat
belt pretensioners for the front outboard
occupants.
Although the seat belt pretensioners cannot
be seen, they are part of the seat belt
assembly. They can help tighten the seat
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
roof-rail airbags, seat belt pretensioners can
help tighten the seat 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 seat belt system will need to
be replaced. See Replacing Seat Belt System
Parts after a Crash 0 35.
Do not sit on the outboard seat belt while
entering or exiting the vehicle or at any
time while sitting in the seat. Sitting on the
seat belt can damage the webbing and
hardware.

This vehicle may have rear seat belt comfort
guides. The guides may provide added seat
belt comfort for older children who have
outgrown booster seats and for some adults.
When installed and properly adjusted, the
comfort guide positions the shoulder belt
away from the neck and head.
The comfort guides for the right rear
outboard seating positions of
three-passenger bench seats are stored in a
pocket on the side of the seatback.
Adjustable comfort guides may be available
through your dealer for the left rear
outboard seating positions of the
three-passenger bench seats and for the
