Questions and Answers About
Safety Belts
Q:
Will I be trapped in the vehicle
after a crash if I am wearing a
safety belt?
A:Youcouldbe — whether you are
wearing a safety belt or not. But
your chance of being conscious
during and after an accident, so
youcanunbuckle and get out, is
muchgreater if you are belted.
And you can unbuckle a safety
belt, even if you are upside down.
Q:If my vehicle has airbags,
why should I have to wear
safety belts?
A:Airbags are supplemental
systems only; so they workwith
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. 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 a crash — even
one that is not your fault — you
and your passenger(s) 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.
How to Wear Safety Belts
Properly
This section is only for people of
adult size.
Be aware that 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, seeOlder Children on
page 1-25orInfants and Young
Children on page 1-28. 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.
Occupants who are not buckled up
can be thrown out of the vehicle in a
crash. And they can strike others
in the vehicle who are wearing
safety belts.
1-14 Seats and Restraint System

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger seating
positions.
Adjust the height so that the shoulder
portion of the belt is centered on the
shoulder. The belt should be away
from the face and neck, but not
falling off of the shoulder. Improper
shoulder belt height adjustment
could reduce the effectiveness of the
safety belt in a crash.
To move it down, press the release
button (A) and move the height
adjuster to the desired position.
You can move the height adjuster up
just by pushing up on the shoulder
belt guide.
After the adjuster is set to the desired
position, try to move it down without
pushing the button to make sure it
has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for the front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety belts
during the early stages of a moderate
to severe frontal, near frontal, or rear
crash if the threshold conditions for
pretensioner activation are met. And,
for vehicles with side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
they will need to be replaced, and
probably other new parts for the
vehicle’s safety belt system. See
Replacing Restraint System Parts
After a Crash on page 1-60.
1-22 Seats and Restraint System

Infants and Young
Children
Everyone in a vehicle needs
protection! This includes infants
and all other children. Neither the
distance traveled nor the age and
size of the traveler changes the
need, for everyone, to use safety
restraints. In fact, the law in every
state in the United States and in
every Canadian province says
children up to some age must be
restrained while in a vehicle.
{CAUTION
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and
the safety belt continues to
tighten. Never leave children
unattended in a vehicle and never
allow children to play with the
safety belts.
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.
Every time infants and young
children ride in vehicles, they should
have the protection provided by
appropriate child restraints.Children who are not restrained
properly can strike other people, or
can be thrown out of the vehicle.
{CAUTION
Never do this.
Never hold an infant or a child
while riding in a vehicle. Due to
crash forces, an infant or a child
will become so heavy it is not
possible to hold it during a crash.
For example, in a crash at only
25 mph (40 km/h), a 12 lb (5.5 kg)
infant will suddenly become a
240 lb (110 kg) force on a
person’s arms. An infant should
be secured in an appropriate
restraint.
1-28 Seats and Restraint System

{CAUTION
Never do this.
Children who are up against, or
very close to, any airbag when it
inates can be seriously injured or
killed. Never put a rear-facing
child restraint in the right front
seat. Secure a rear-facing child
restraint in a rear seat. It is also
better to secure a forward-facing
child restraint in a rear seat. If you
must secure a forward-facing child
restraint in the right front seat,
always move the front passenger
seat as far back as it will go.

seat; an older child riding in a booster
seat; and children, who are large
enough, using safety belts.
A label on the sun visor says, “Never
put a rear-facing child restraint 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
airbag inates. This is because
the back of the rear-facing child
restraint would be very close to
the inating airbag. A child in a
forward-facing child restraint can
be seriously injured or killed if the
right front passenger airbag
inates and the passenger seat
is in a forward position.
(Continued)
CAUTION (Continued)
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though it is
turned off.
Secure rear-facing child restraints
in a rear seat, even if the
airbag is off. If you 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.
SeePassenger Sensing System
on page 1-54for additional
information.When securing a child restraint in a
rear seating position, study the
instructions that came with the
child restraint to make sure
it is compatible with this vehicle.
Wherever a child restraint is
installed, be sure to secure the
child restraint properly.
Keep in mind that an unsecured
child restraint can move around in
a collision or sudden stop and injure
people in the vehicle. Be sure to
properly secure any child restraint in
the vehicle — even when no child
is in it.
