Q: If my vehicle has airbags, whyshould I have to wear safety
belts?
A: Airbags are supplemental
systems only. They work with
safety belts —not instead of
them. Whether or not an airbag
is provided, all occupants still
have to buckle up to get the
most protection.
Also, in nearly all states and in
all Canadian provinces, the law
requires wearing safety belts.
How to Wear Safety Belts
Properly
This section is only for people of
adult size.
There are special things to know
about safety belts and children, and
there are different rules for smaller
children and infants. If a child will be
riding in the vehicle, see Older
Children 099 orInfants and Young
Children 0101. Follow those rules
for everyone's protection. It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are
wearing safety belts.
There are important things to know
about wearing a safety belt properly.
.
Sit up straight and always keep
your feet on the floor in front
of you.
. Always use the correct buckle
for your seating position.
. Wear the lap part of the belt low
and snug on the hips, just
touching the thighs. In a crash,
this applies force to the strong pelvic bones and you would be
less likely to slide under the lap
belt. If you slid under it, the belt
would apply force on your
abdomen. This could cause
serious or even fatal injuries.
. Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best
able to take belt restraining
forces. The shoulder belt locks if
there is a sudden stop or crash.
{Warning
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
. Never allow the lap or
shoulder belt to become
loose or twisted.
. Never wear the shoulder
belt under both arms or
behind your back.
. Never route the lap or
shoulder belt over an
armrest.

80 Seats and Restraints
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt except for
the center front passenger position,
if equipped, which has a lap belt.
SeeLap Belt 085.
If you are using a rear seating
position with a detachable safety
belt, and the safety belt is not
attached, see Third Row Seats 076
for instructions on reconnecting the
safety belt to the mini-buckle.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see
“Seats” in the Index.
2. Pick up the latch plate and pull
the belt across you. Do not let
it get twisted.
The lap-shoulder belt may lock
if you pull the belt across you
very quickly. If this happens, let
the belt go back slightly to
unlock it. Then pull the belt
across you more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be
engaged. If this happens, let
the belt go back all the way
and start again. Engaging the child restraint
locking feature in the front
outboard seating position may
affect the passenger sensing
system. See
Passenger
Sensing System 093.
For front seating positions,
if the webbing locks in the latch
plate before it reaches the
buckle, tilt the latch plate flat to
unlock.
