WARNING! Do not wear the shoulder belt under
your arm or otherwise out of position. In a crash
your body would move too far forward, increasing
the chance of head and neck injury. Also, the belt
would apply too much force to the ribs, which are
not as strong as your shoulder bones, and could
cause you to suffer internal injuries. Wear the
shoulder belt over your shoulder (see “Safety
Restraint Belts” on page 44).
WARNING! Do not twist the belt in the process of
putting it on. A twisted belt will not work as well
to protect you. In a crash, the full width of the
belt would not be protecting you. A twisted belt
could cut into your body and cause serious inju-
ries. Straighten the belt before buckling it. If you
are unable to wear it without twisting it, have
your dealer or service person repair it as soon
as possible.
Safety Restraint Tips
• Anyone riding in your vehicle should wear a seat belt. A
responsible operator sees to it that everyone in the vehi-
cle rides safely—and that means with a seat belt.
• Do not strap in more than one person with each belt.
• Do not wear a belt over rigid or breakable objects in or on
your clothing, such as eye glasses, pens, keys, etc., as
these may cause injury in an accident.
• Several layers of heavy clothing may interfere with
proper positioning of belts and reduce the overall effec-
tiveness of the system.
• Keep belt buckles free of any obstruction that may pre-
vent secure locking.
• Damaged or worn belts, subjected to excessive stretch
forces from crashes, cuts or tears, or normal wear, must
be replaced—they may not protect you if you have an
accident.
• If belts show damage to any part of assembly, such as
webbing, bindings, buckles or retractors, they must be
replaced.
• Do not allow safety belts to become damaged by getting
caught in door or seat hardware, or rubbing against
sharp objects.
• The belts must be kept clean or the retractors may not
work properly.
• Never bleach or dye seat belts: chemicals can weaken
them. Do, however, keep them clean by following the
care label on the belts. Let them dry completely before
allowing them to retract.
