This section describes how to use the
seat belts properly. It also describessome of the things not to do when
using seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and
make sure all passengers have fas-
tened their seat belts before starting
any trip. Air bags are designed tosupplement the seat belt as an addi-
tional safety device, but they are not
a substitute. Most counties require all
occupants of a vehicle to wear seat
belts.
SSEE AA TT BB EELLTT SS
Seat belts must be used by ALL
passengers whenever the vehi-
cle is moving. Take the followingprecautions when adjustingand wearing seat belts:
ALWAYS properly restrain
children under age 13 in therear seats.
(Continued)
WARNING
(Continued)
NEVER allow children to ride
in the front passenger seat. If
a child age 13 or older must be
seated in the front seat, move
the seat as far back as possi-
ble and properly restrain themin the seat.
NEVER allow an infant or child
to be carried on an occupant’slap.
NEVER ride with the seatback
reclined when the vehicle is
moving.
Do not allow children to share a seat or seat belt.
Do not wear the shoulder belt
under your arm or behind your
back.
Always wear both the shoul-
der portion and lap portion ofthe lap/shoulder belt.
Do not use the seat belt if it is
twisted. A twisted seat belt
will not protect you properlyin an accident.
(Continued)
(Continued)
Do not use a seat belt if the
webbing or hardware is dam-
aged.
Do not latch the seat belt into
the buckles of other seats.
NEVER unfasten the seat belt
while driving. This may cause
loss of vehicle control result-ing in an accident.
Make sure there is nothing in
the buckle interfering with the
seat belt latch mechanism.
This may prevent the seat belt
from fastening securely.
No modifications or additions
should be made by the user
which will either prevent the
seat belt adjusting devices
from operating to remove
slack, or prevent the seat belt
assembly from being adjusted
to remove slack.
