Seat Belts and Supplemental
Restraint System (SRS)
Your vehicle is equipped with seat
belts for all seats, emergency
tensioning retractors for the front seats,
as well as airbags and knee bolsters for
driver and front passenger.
Seat Belts
Important!
Laws in most states and all Canadian
provinces require seat belt use.
All states and provinces require use of
child restraints that comply with U.S.
Federal Motor Vehicle Safety Standard
213 and Canadian Motor Vehicle
Safety Standard 213.1.
We strongly recommend their use.
Warning!
Never ride in a moving vehicle with
the seat back reclined. Sitting in an
excessively reclined position can be
dangerous. You could slide under
the seat belt in a collision. If you
slide under it, the belt would apply
force at the abdomen or neck. That
could cause serious or even fatal
injuries. The seat back and seat belts
provide the best restraint when the
wearer is in an upright position and
belts are properly positioned on the
body.
Seat Belt Warning System
With the key in steering lock position
2, an audible warning sounds for a
short time if the driver's seat belt is not
fastened.
If you are ever in an accident, your
injuries can be considerably more
severe without your seat belt
properly buckled. Without your seat
belt buckled, you can hit the interior
of the vehicle or be ejected from it.
You can be seriously injured or
killed.
In the same crash, the possibility for
injury or death is lessened with your
seat belt buckled.
