Questions and Answers About
Safety Belts
Q:Will I be trapped in the vehicle after an
accident if I am wearing a safety belt?
A:Youcouldbe — whether you are wearing a
safety belt or not. But you can unbuckle a
safety belt, even if you are upside down. And
your chance of being conscious during and
after an accident, so youcanunbuckle and get
out, ismuchgreater if you are belted.
Q:If my vehicle has airbags, why should I
have to wear safety belts?
A:Airbags are in many vehicles today and will be
in most of them in the future. But they are
supplemental systems only; so they workwith
safety belts — not instead of them. Every
airbag system ever offered for sale has
required the use of safety belts. Even if you
are in a vehicle that has airbags, you still
have to buckle up to get the most protection.
That is true not only in frontal collisions,
but especially in side and other collisions.
Q:If I am a good driver, and I never drive far
from home, why should I wear safety belts?
A:You may be an excellent driver, but if you are
in an accident — even one that is not your
fault — you and your passengers can be hurt.
Being a good driver does not protect you
from things beyond your control, such as
bad drivers.
Most accidents occur within 25 miles (40 km)
of home. And the greatest number of
serious injuries and deaths occur at speeds
of less than 40 mph (65 km/h).
Safety belts are for everyone.

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are part of the safety belt
assembly. They help tighten the safety belts
in a moderate to severe frontal or near frontal
crash if the threshold conditions for pretensioner
activation are met. And, if your vehicle has
side impact rollover airbags, safety belt
pretensioners can help tighten the safety belts
in a side crash or a rollover event.
Pretensioners work only once. If they activate
in a crash, you will need to get new ones,
and probably other new parts for your safety belt
system. SeeReplacing Restraint System Parts
After a Crash on page 91.
Safety Belt Extender
If the vehicle’s safety belt will fasten around you,
you should use it.
But if a safety belt is not long enough, your dealer
will order you an extender. When you go in to
order it, take the heaviest coat you will wear,
so the extender will be long enough for you.
To help avoid personal injury, do not let someone
else use it, and use it only for the seat it is
made to t. The extender has been designed for
adults. Never use it for securing child seats.
To wear it, just attach it to the regular safety belt.
For more information see the instruction sheet
that comes with the extender.

{CAUTION:
Children who are up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer protection for
adults and older children, but not for
young children and infants. Neither the
vehicle’s safety belt system nor its airbag
system is designed for them. Young
children and infants need the protection
that a child restraint system can provide.
47

Where to Put the Restraint
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding
in a booster seat.
If your vehicle has a rear seat that will
accommodate a rear-facing child restraint, a label
on your sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk
to the rear-facing child is so great, if the
airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates.
CAUTION: (Continued)
CAUTION: (Continued)
This is because the back of the
rear-facing child restraint would be very
close to the inating airbag.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
If you need to secure a forward-facing
child restraint in the right front seat,
always move the front passenger seat as
far back as it will go. It is better to secure
the child restraint in a rear seat.
54

If your vehicle does not have a rear seat that
will accommodate a rear-facing child restraint,
never put a child in a rear-facing child restraint
in the right front passenger seat unless the
passenger airbag status indicator shows off and
the airbag is off. Here is why:
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag.Be sure the airbag is off
before using a rear-facing child restraint
in the right front seat position.
CAUTION: (Continued)
CAUTION: (Continued)
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be
transported in vehicles with a rear seat
that will accommodate a rear-facing child
restraint, whenever possible.
If you need to secure a forward-facing
child restraint in the right front seat,
always move the front passenger seat as
far back as it will go. It is better to secure
the child restraint in a rear seat.
Wherever you install a child restraint, be sure to
secure the child restraint properly.

Securing a Child Restraint in the
Center Rear Seat Position
Many child restraints are too wide to be correctly
secured in the center rear seat, although some
of them will t there. If the center seat position is
too narrow for your child restraint, secure it in
a rear outside seat position.
If you secure a child restraint in the center seat
position, follow the instructions inSecuring a
Child Restraint in a Rear Outside Seat Position
on page 63.
Securing a Child Restraint in the
Right Front Seat Position
Your vehicle has a right front passenger’s
airbag. A rear seat is a safer place to secure
a forward-facing child restraint. SeeWhere to
Put the Restraint on page 54.
In addition, your vehicle has a passenger sensing
system. The passenger sensing system is
designed to turn off the right front passenger’s
frontal airbag when an infant in a rear-facing infant
seat or a small child in a forward-facing child
restraint or booster seat is detected. See
Passenger Sensing System on page 82and
Passenger Airbag Status Indicator on page 202
for more information on this including important
safety information.
