or the safety belts!
With safety belts, you slow down as
the vehicle does. You get more
time to stop. You stop over more
distance, and your strongest bones
take the forces. That is why
safety belts make such good sense.
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.
Seats and Restraint System 1-17

You can move the height adjuster
up 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 1-62.
Rear Safety Belt Comfort
Guides
Rear shoulder belt comfort guides
may provide added safety belt
comfort for older children who have
outgrown booster seats and for
some adults. When installed on a
shoulder belt, the comfort guide
positions the shoulder belt away
from the neck and head.
There is a guide for each
outboard passenger position
in the second row seat and all
passenger positions in the third row.Here is how to install a comfort
guide to the safety belt:
1. For the outboard positions,
remove the guide from its storage
clip on the interior body.
For the third row center position,
locate the comfort guide which
is located in a storage pocket,
at the top of the seat, under
the headrest on the driver’s
side of the vehicle.Outboard Positions
Seats and Restraint System 1-25

CAUTION (Continued)
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
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.
Seats and Restraint System 1-31

{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.
{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.
Q:What are the different types of
add-on child restraints?
A:Add-on child restraints, which are
purchased by the vehicle’s
owner, are available in four basic
types. Selection of a particular
restraint should take into
consideration not only the child’s
weight, height, and age but also
whether or not the restraint will be
compatible with the motor vehicle
in which it will be used.
1-32 Seats and Restraint System

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 1-55for 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.
1-36 Seats and Restraint System

Securing a Child
Restraint in the Right
Front Seat Position
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint
on page 1-35.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right
front passenger frontal airbag and
seat-mounted side impact airbag
under certain conditions. See
Passenger Sensing System on
page 1-55andPassenger Airbag
Status Indicator on page 3-36
for more information, including
important safety information.
A label on the 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
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.
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.
(Continued)
CAUTION (Continued)
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 1-55for additional
information.
If the child restraint has the LATCH
system, seeLower Anchors and
Tethers for Children (LATCH) on
page 1-37for how and where to
install the child restraint using
LATCH. If a child restraint is secured
using a safety belt and it uses a top
tether, seeLower Anchors and
Tethers for Children (LATCH) on
page 1-37for top tether anchor
locations.
Seats and Restraint System 1-45

Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with
the child restraint say that the top
strap must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether
be attached.You will be using the lap-shoulder
belt to secure the child restraint
in this position. Follow the
instructions that came with
the child restraint.
1. Move the seat as far back as it
will go before securing the
forward-facing child restraint.
When the passenger sensing
system has turned off the
right front passenger frontal
airbag and seat-mounted side
impact airbag, the off indicator on
the passenger airbag status
indicator should light and stay lit
when the vehicle is started.
SeePassenger Airbag Status
Indicator on page 3-36.
2. Put the child restraint on
the seat.3. Pick up the latch plate, and run
the lap and shoulder portions of
the vehicle’s safety belt
through or around the restraint.
The child restraint instructions
will show you how.
4. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
