3-18 Seats and Restraints
2. Attach the adjustable comfort
guide to the anchor loop by
threading the hook through
the loop.
3. Place the guide over the belt,
and insert the two edges of the
belt into the slots of the guide.
4. Be sure that the belt is not
twisted and it lies flat. The
elastic cord must be under the
belt and the guide on top.
5. The elastic cord on the comfort
guide is adjustable. Make it
longer or shorter by squeezing
both ends of the plastic adjuster
and pulling on the elastic cord or
the guide.
6. Adjust the guide 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 comfort guide
adjustment could reduce the
effectiveness of the safety belt in
a crash.
Warning
A safety belt that is not properly
worn may not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. The shoulder
belt should go over the shoulder
and across the chest. These parts
of the body are best able to take
belt restraining forces.
