out of P (Park). This feature may not allow
the vehicle to shift out of P (Park) if an
object, such as a briefcase, handbag, grocery
bag, laptop, or other electronic device, is on
the front passenger seat. If this happens,
remove the object from the seat or buckle
the seat belt to shift out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains unbuckled,
the DIC message will turn off after several
seconds and the vehicle can be shifted out
of P (Park). See“Seat Belts”and“Child
Restraints” in the Index for information
about the importance of proper
restraint use.
If the driver seat belt, and in some vehicles
the front passenger seat belt, is unbuckled
when driving, the seat belt reminder chime
and light(s) will come on. See Seat Belt
Reminders 093. This feature may not
function properly if the airbag readiness
light is on. See Airbag Readiness Light 094.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
in the vehicle, see Older Children058 or Infants and Young Children
060. Review
and follow the rules for children in addition
to the following rules.
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 seat belts.
There are important things to know about
wearing a seat belt properly.
.Sit up straight and always keep your feet
on the floor in front of you (if possible).
.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 seat belt
properly.
