object toward a person. This could cause
severe injury or even death. Secure
objects away from the area in which an
airbag would inflate.

50 Seats and Restraints
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 seat belt in a crash. See
How to Wear Seat Belts Properly046.
To move the shoulder belt height adjuster
down, push up on the release button and
move the height adjuster to the desired position. You can move the height adjuster
up by pushing up on the shoulder belt
guide.
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.
Seat Belt Pretensioners
This vehicle has seat belt pretensioners for
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. Seat belt pretensioners can also 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 052. 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.
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may provide
added seat belt comfort for older children
who have outgrown booster seats and for
some adults. When installed on a shoulder
belt, the comfort guide positions the
shoulder belt away from the neck and head.
Comfort guides are available through your
dealer for the rear outboard seating
positions. Instructions are included with the
guides.
Seat Belt Use During Pregnancy
Seat belts work for everyone, including
pregnant women. Like all occupants, they
are more likely to be seriously injured if
they do not wear seat belts.
